Mean of 5 draws (0.12, 0.13, 0.24, 0.23, 0.24). (0) Not resolved: EDGAR shows no public OpenAI S-1 and the June 8, 2026 draft S-1 remains confidential and unamended; no IPO has closed. (a) About 15 months remain to the 2028-01-01 close, possibly less if the 'one year after issuance' clause sets expiration around late September 2027; OpenAI must both complete an IPO and give Altman a personal high-vote share class before initial closing. (b) Status quo: multiple 2025-2026 sources, including May 2026 court filings, say Altman holds zero OpenAI equity; the only super-voting instrument (Class N) belongs to the nonprofit Foundation; the IPO is being deferred, with Altman calling 2026 'ill-advised', a $30B+ private bridge round at ~$1.4T, and CFO readiness doubts. Nothing changing means No. (c) NO: the IPO slips past the window, or it closes with Foundation Class N control and Altman holding no personal high-vote stock. (d) YES: OpenAI lists in 2027 and the board revives the shelved 2024 equity discussion, granting Altman a founder high-vote class mirroring Anthropic's reported 50.1% co-founder voting bloc. I put P(IPO closes in window) at ~40-50% and P(personal super-voting grant | IPO) at ~20-25%, giving ~10%, nudged slightly up for confidential-S-1 unknowns. The Kalshi anchor is 31%, already falling from 41-47%, and I see no evidence supporting that level.

Planner reasoning
This is a Kalshi question, so kalshi_direct is the price anchor. The question depends on whether OpenAI IPOs before 2028 and on the share structure Altman holds after the PBC recapitalization. Related Kalshi and Polymarket markets on OpenAI IPO timing give a probability for the IPO gate. SEC EDGAR (any S-1) is the resolution source, Wikipedia provides background on the structure, and one targeted search checks reporting on Altman's equity and any dual-class plans.

Research loops, bottom lines
- current state: As of early October 2026, OpenAI's governance runs through the nonprofit Foundation's contractual board-appointment rights (not a dual-class super-voting share structure), Altman is consistently reported to hold zero direct OpenAI equity, and the IPO itself has been pushed to 2027 or later — so there is currently no disclosed mechanism, plan, or filing suggesting Altman would hold super-voting shares at an eventual IPO.
- base rate: The general tech-IPO base rate strongly favors founders retaining personal super-voting shares (roughly half of recent tech IPOs, and the norm among AI-lab peers like SpaceX/Musk and reportedly Anthropic), but OpenAI is a structural outlier: its only super-voting instrument (Class N) is institutionally held by the nonprofit Foundation, and Altman has consistently and repeatedly held zero personal equity, with a prior 7% grant proposal frozen rather than implemented — so the specific reference cl

- [2026-09-12] CEO Sam Altman told Fortune
"I actually think that, given everything happening with safety, right now would be an ill-advised moment to go public, and we don't feel pressure on that,"
and when pressed said 2027, not 2026, is the likely IPO year. https://fortune.com/2026/09/12/sam-altman-openai-ipo-delay-ill-advised-moment-safety-concerns/
- [2026-06-08] OpenAI confidentially filed a draft S-1 registration statement with the SEC, with Goldman Sachs and Morgan Stanley reportedly working on the offering, but no IPO date, structure, or share classes have been disclosed. https://smartasset.com/investing/openai-stock-ipo
- [2025-10-28] OpenAI completed its restructuring into "OpenAI Group PBC" (a Delaware public benefit corporation); the nonprofit "OpenAI Foundation" holds roughly a 26% equity stake and, per the Delaware AG, retains
"sole power to appoint and remove all PBC board members"
rather than via super-voting shares. (see Transformer News recap) https://www.transformernews.ai/p/what-you-need-to-know-about-the-openai-restructure-sam-altman-pbc-foundation
- [2025-10-28] Reporting on the restructuring states explicitly that
the foundation's board members — who largely defer to Altman — appointed to the board of the new PBC
, and separately that
"Altman is, reportedly, not taking equity in the new company."
https://www.transformernews.ai/p/what-you-need-to-know-about-the-openai-restructure-sam-altman-pbc-foundation
- [2026-09-03] A portfolio-tracking analysis citing May 2026 court filings concludes
"May 2026 court filings show Sam Altman holds no direct OpenAI equity, despite running the company that recently raised at a $730B valuation."
https://www.startuphub.ai/ai-news/ai-figures/2026/figure-sam-altman-venture-portfolio-breakdown-2026-05-27
- [2026-08-30] Governance explainer states control runs through the nonprofit Foundation's board-appointment power (not share classes):
"The board of the nonprofit OpenAI Foundation has 'special voting and governance rights' that allow it to appoint all members of the for-profit OpenAI Group's board of directors."
https://www.klover.ai/openai_ipo_governance_and_control_deep_dive_comprehensive_research_2026/
- [2026-08-30] Same source notes Altman's unusual compensation:
"Altman holds no direct equity in OpenAI and earned a salary of $66,000 in 2024."
https://www.klover.ai/openai_ipo_governance_and_control_deep_dive_comprehensive_research_2026/
- [2026-08-30] A recent ownership explainer confirms current cap-table composition post-recap: Microsoft ~27%, Foundation ~26%, employees/investors ~47%, and reiterates
"Sam Altman owns zero equity in OpenAI... Still true after the recap."
https://visionarytalks.com/who-owns-chatgpt-openai/
- [2026-07-02] Separately, Altman has proposed donating up to 5% of OpenAI's equity to a U.S. sovereign wealth fund/government vehicle; such reported talks involve ordinary (non-voting or passive) government stakes, not Altman personal super-voting shares. https://techcrunch.com/2026/07/02/openai-proposed-donating-5-of-its-equity-to-a-us-sovereign-wealth-fund/
- [2026-09-18] A revenue/ownership tracker reiterates the Foundation "controls" governance via board-appointment rights despite minority equity, with
"Its CEO holds no equity."
https://www.revenuememo.com/p/who-owns-openai
- [2025-09-26 reported] Historical reporting shows OpenAI once considered a 7% equity grant to Altman during the 2024 for-profit transition talks, but Altman denied plans at the time and no such grant was implemented; the later 2025 restructuring confirmed he took no equity. https://dc.fortune.com/2024/09/27/sam-altman-openai-billionaire-equity-stake
- [2026-10-01] An IPO tracker summarizes that OpenAI's current ownership table lists only common-type stakeholders (Foundation, Microsoft, employees, investors) with
"Venture capital investors include Tiger Global, Andreessen Horowitz, Sequoia Capital... CEO Sam Altman has said he does not own an equity stake."
https://accessipos.com/openai-stock-ipo/
BOTTOM LINE: As of early October 2026, OpenAI's governance runs through the nonprofit Foundation's contractual board-appointment rights (not a dual-class super-voting share structure), Altman is consistently reported to hold zero direct OpenAI equity, and the IPO itself has been pushed to 2027 or later — so there is currently no disclosed mechanism, plan, or filing suggesting Altman would hold super-voting shares at an eventual IPO.
NOT FOUND: No SEC S-1/F-1 or other registration-statement text (the filing remains confidential) describing planned share classes or voting structure for the IPO; no report of any board decision granting Altman equity (super-voting or otherwise) since the 2025 restructuring; no confirmed IPO date or closing to apply the "initial closing" test to.
report: base rate
- [2026-10-03 lookback, facts as of 2025-10-28] After OpenAI's recapitalization,
OpenAI said its Foundation retains full governance control over the for-profit group through ownership of Class N Common Stock, giving it the exclusive ability to appoint or remove board members and block changes to the for-profit's mission, charter or sale.
The super-voting instrument is held by the nonprofit Foundation entity, not by Sam Altman personally. (bankinfosecurity.com)
- [2026-07-22] Per Fortune commentary,
the OpenAI Foundation—still controls the company... its control derives from a special share of Class N stock through which the nonprofit has almost complete control over the composition of the company's board, as well as sole authority over all "safety and security decisions."
Altman sits on the Foundation board but is one of nine directors (eight independent), not the holder of the Class N share himself (medium.com/@cognidownunder, 2026 source).
- [2026-09-xx, multiple outlets corroborate] Reporting consistently states
Unusually for a tech CEO running a company valued in the hundreds of billions, Altman holds no equity in OpenAI.
This has been true since at least 2024 and remained so through 2026 court-filing disclosures.
- [2026-05] Court testimony/filings in the Musk v. OpenAI trial, reported by Forbes, confirmed
Altman holds no direct equity in OpenAI, per those same filings as reported by BanklessTimes, despite running a company that closed a $110 billion funding round at a $730 billion valuation in February 2026.
- [2024-09-27] Historical base rate for an equity grant to Altman: a 7% stake was floated but
Altman told OpenAI employees in an all-hands meeting Thursday that there are no plans to give him a "giant equity stake" in the newly for-profit enterprise.
That 7% proposal has remained frozen as of mid-2026 reporting.
- [2026-09-12] Altman has pushed the IPO timeline out:
OpenAI won't go public in this year as the artificial intelligence company focuses on addressing safety-related concerns... Altman said this year would be an "ill-advised moment" for initial public offering and that a listing won't take place until next year.
This extends the window before any resolution-relevant "initial closing" could occur, but still fits within the market's expiration window (14 days after shares trade or one year after issuance, by 2028-01-01 close).
- [Outside-view, tech-IPO reference class] Dual-class/super-voting structures are common at IPO generally:
only 15 per cent of the US Tech IPOs in 2012 featured dual-class share structures, this share increased to 50 per cent in 2022
, and peer "AI lab" comparables lean the same way — e.g.,
a two-tier structure would give select shareholders stock with extra voting power that would allow them to dominate decision making... allow insiders such as Musk to maintain control of the company even with a minority stake
for SpaceX, and Anthropic reporting indicates
the dual-class structure being prepared would solve that problem by design. Such structures are not unusual in technology companies: at Meta, Zuckerberg holds 60 percent voting control through super-voting shares despite owning a fraction of the company's economic interest.
So among "AI unicorn" IPO peers, founder super-voting personal shares are close to the norm — except OpenAI is structurally unusual.
- [Key distinguishing fact] OpenAI's control mechanism is institutional, not personal: the Class N super-voting share sits with the nonprofit Foundation (a 501(c)(3)), a structure the EyesOnOpenAI coalition calls
In OpenAI, investors aren't investing in a typical corporation—they're putting money into a company that's ultimately controlled by a 501(c)(3) charitable nonprofit. With this unconventional and unprecedented structure—OpenAI will be the first 501(c)(3) charity to take a controlled entity public.
This is categorically different from the Zuckerberg/Musk/Spiegel reference class where the founder personally holds the super-voting stock.
- [Historical base rate for "founder claims no equity, then gets a grant before IPO"] No confirmed precedent found of a major tech-company CEO who publicly held zero equity for years suddenly receiving personal super-voting shares immediately pre-IPO; the closest analog (Altman's own 2024 proposed 7% stake) was shelved rather than granted.
- [2026-08-19] Timeline context: OpenAI's CFO said
On August 19, 2026, CFO Sarah Friar told employees that OpenAI "will be a public company in 2027," or sooner if the business keeps accelerating.
Combined with the September "ill-advised" comments and the pursuit of a private $1.2T round instead, actual IPO timing is uncertain and could fall late in or after the market's 2028-01-01 window, though the contract's "no IPO" resolves No regardless.
BOTTOM LINE: The general tech-IPO base rate strongly favors founders retaining personal super-voting shares (roughly half of recent tech IPOs, and the norm among AI-lab peers like SpaceX/Musk and reportedly Anthropic), but OpenAI is a structural outlier: its only super-voting instrument (Class N) is institutionally held by the nonprofit Foundation, and Altman has consistently and repeatedly held zero personal equity, with a prior 7% grant proposal frozen rather than implemented — so the specific reference class for "this founder personally holds super-voting shares" argues against resolution, absent a late, unprecedented reversal before any actual IPO closes.
NOT FOUND: No primary SEC S-1/S-1 draft text (confidential, not public) detailing final share-class/voting structure for the OpenAI IPO; no confirmed report of any personal equity or super-voting grant to Altman since the 2024 proposal was shelved; no confirmed IPO date.
report: yes case
YES means: At the initial closing of OpenAI's eventual IPO, Sam Altman personally (or via a trust/entity he beneficially controls) holds a share class with more votes-per-share than the shares sold to the public — e.g., a founder "super-voting" class analogous to those at Meta, Alphabet, SpaceX, or Anthropic.
- [2026-09-xx/2026-10-01] The clearest live mechanism for YES is the Anthropic precedent that OpenAI's own bankers and lawyers are watching in real time: Anthropic's confidential S-1 (filed June 1, 2026, one week before OpenAI's own draft S-1) was followed by reporting that Anthropic is
preparing to give Amodei and other co-founders a special class of stock with enhanced voting rights, per Reuters reporting via The Information
, and a subsequently fetched tracker states Anthropic's "public IPO filing filed in September now locks in...a 50.1 percent voting bloc reserved for seven co-founders," confirming this moved from rumor to an actual filed structure at OpenAI's closest IPO-track peer. https://provenbrief.com/story/the-ai-lab-control-tracker-equity-vs-voting-power-at-openai-anthropic-meta-googl
- [2026-10-03, tracker] The same tracker, current as of today, frames the broader "AI lab control" reference class (Alphabet, Meta, SpaceX, Anthropic) as one where founder-held super-voting stock is the structural norm, with multiples (control premiums) ranging from about 2x to 4.7x votes-per-equity-unit, making OpenAI the current outlier rather than the expected end-state once it actually lists. https://provenbrief.com/story/the-ai-lab-control-tracker-equity-vs-voting-power-at-openai-anthropic-meta-googl
- [2024-09-26, still open as of 2026] OpenAI's own board chair Bret Taylor stated on the record that
"The board has had discussions about whether it would be beneficial to the company and our mission to have Sam be compensated with equity, but no specific figures have been discussed nor have any decisions been made"
— this discussion was never formally closed or rescinded; it was merely "frozen," leaving an open board-level channel through which a founder-equity/voting grant could still be adopted before an IPO closing.
- [2026-02-18] Reporting as recently as February 2026 continued to flag that any such Altman equity package would most plausibly be formalized around a liquidity event: Fortune noted the "AI boom is minting massive wealth" even as Altman's compensation stayed nominal, implying the natural trigger point for any grant is the IPO process itself, not the status quo. https://fortune.com/2026/02/18/openai-chatgpt-creator-record-million-dollar-equity-compensation-ai-tech-talent-war-career-retention-sam-altman-millionaire-staff/
- [2026-07-22] Separately from Altman's personal equity, OpenAI's actual Class N super-voting share already exists and is structurally capable of being reassigned or supplemented: Fortune commentary notes
"OpenAI's nonprofit—the OpenAI Foundation—still controls the company. Its control derives from a special share of Class N stock through which the nonprofit has almost complete control over the composition of the company's board, as well as sole authority over all 'safety and security decisions'"
— demonstrating OpenAI already operates a dual-class voting architecture into which a personal Altman super-voting instrument could be inserted without a wholesale restructuring.
- [2026-07] The same piece notes this Class N arrangement is unresolved and under active regulatory scrutiny, with a coalition explicitly flagging it as "unprecedented" and pushing the SEC to force fuller governance disclosure before any IPO — meaning the final, binding share-class structure for the IPO is not yet locked in and remains open to late changes, including changes that could add Altman personally to a high-vote class. https://fortune.com/2026/07/22/openai-foundation-class-n-stock-board-control-ipo/
- [2026-07-02] Altman has also been separately reported as negotiating non-standard equity arrangements (e.g., a proposed 5% donation to a U.S. sovereign vehicle) and, per an August 2026 report, privately discussed giving the government shares before reportedly souring on the idea — evidence that bespoke, non-public-market share arrangements involving Altman personally are actively being negotiated in parallel with IPO planning, the same kind of negotiation that could yield a personal voting-share grant. https://washingtonsun.com/technology/sam-altman-privately-rejected-open-ai-government-equity
- [2026-09-12 confirmed earlier, reaffirmed] The slipped IPO timeline (now 2027 at the earliest per Altman's own September 12 remarks) is not a bar to a YES outcome; it extends the window during which the board could still finalize and disclose a founder super-voting grant, since the Kalshi contract's resolution window runs to 2028-01-01 and measures votes only "at the initial closing" of whatever IPO eventually occurs.
BOTTOM LINE: The strongest case for YES is not that Altman currently holds equity (he does not), but that (1) OpenAI already operates a dual-class voting structure (Class N) that could be extended to Altman personally, (2) the board has an open, never-withdrawn discussion about compensating him with equity, and (3) OpenAI's closest IPO-track peer, Anthropic, moved from rumored to filed founder super-voting shares (a 50.1% co-founder voting bloc) in its own September 2026 S-1 — establishing a live, near-term precedent that could be mirrored in OpenAI's eventual registration statement before any IPO closing.
NOT FOUND: No OpenAI board resolution, compensation-committee filing, or draft S-1 excerpt (the filing remains confidential) showing any actual decision to grant Altman personal voting or economic equity since the 2024 proposal was shelved; no confirmed report that OpenAI is specifically modeling an Anthropic-style founder voting bloc for Altman.
report: no case
YES means: At the initial closing of a qualifying OpenAI IPO, Sam Altman personally (including via trusts/entities) holds shares carrying more votes per share than the shares sold to the public — i.e., a personal super-voting/dual-class stake, not merely board influence via the nonprofit Foundation.
- [2026-09-29/30] OpenAI is now pursuing a **private bridge round** of at least $30 billion at ~$1.4 trillion pre-money, explicitly "instead" of a 2026 public offering, with the round "designed to give OpenAI additional runway while it defers a public listing" — pushing any possible IPO closing further out and reducing near-term urgency to design (or disclose) a founder super-voting share class. (https://qz.com/openai-funding-round-30-billion-valuation-092926)
- [2026-09-29] Reporting states plainly this new capital is explicitly a "pre-IPO funding round," with Bloomberg describing it as "bridge financing after OpenAI pushed back plans for a public listing," reinforcing that no IPO closing (the resolution trigger) is imminent. (https://www.blockhead.co/2026/09/30/openai-seeks-at-least-30-billion-at-1-4-trillion-valuation-as-bridge-to-delayed-ipo/)
- [2026-10-01/02] A governance/IPO tracker updated October 2, 2026 confirms the corporate-control mechanism remains unchanged since the October 2025 conversion: control runs through the nonprofit's Class N Common Stock giving it "sole power to appoint and remove the entire PBC board at any time," with no new share class or personal Altman voting instrument disclosed in any subsequent filing or update. (https://www.useluminix.com/reports/company-overviews/what-do-we-know-about-the-openai-ipo)
- [2026-10-02] The same tracker notes "no public filing, amendment or withdrawal has been reported since" the June 8 confidential S-1 submission — meaning nine-plus months after the initial draft, there is still zero public text on any proposed share-class/voting structure for the eventual offering, let alone one granting Altman super-voting shares.
- [2026-09-12, reaffirmed 2026-09-29] Altman's own words — "I would say not 2026... We've got a lot of stuff to do" — combined with the pivot to private financing show deliberate IPO deferral, extending the status-quo period (zero personal equity, no super-voting instrument) well into the question's window before any "initial closing" could even occur. (https://www.blockhead.co/2026/09/30/openai-seeks-at-least-30-billion-at-1-4-trillion-valuation-as-bridge-to-delayed-ipo/)
- [2026-09-29] CFO Sarah Friar has "separately raised doubts about the company's readiness to meet public-market regulatory requirements on Altman's preferred IPO timeline," per WSJ reporting, an internal-readiness signal that further delays any IPO closing against which the super-voting test could even be applied. (https://qz.com/openai-funding-round-30-billion-valuation-092926)
- [2026-09-30] Competitive dynamics show Anthropic, not OpenAI, is the frontline IPO candidate — reporting describes "a leaked Anthropic prospectus set[ting] a $2 trillion bar for AI listings," while OpenAI opts to raise privately — consistent with OpenAI's IPO sliding later in (or past) the contract's window rather than imminently testing any share-class question. (https://www.blockhead.co/2026/09/30/openai-seeks-at-least-30-billion-at-1-4-trillion-valuation-as-bridge-to-delayed-ipo/)
- [2024-09-26/27, status quo unchanged through 2026] The only historical instance of a proposed personal equity grant to Altman — a floated 7% stake during the 2024 for-profit transition talks — was explicitly denied by Altman at the time ("there are no current plans here") and was superseded by the October 2025 restructuring in which he took zero equity; no subsequent proposal of any kind (super-voting or otherwise) has surfaced in over two years of reporting. (https://dc.fortune.com/2024/09/27/sam-altman-openai-billionaire-equity-stake)
- [Resolution-mechanics point] Because the contract requires measurement "at the initial closing of OpenAI's IPO" and resolves No "if no qualifying IPO closes by expiration," the combination of (a) a now-explicit private bridge round substituting for the IPO, (b) Altman's own "not 2026" framing, and (c) persistent CFO-level readiness concerns raises real odds that no qualifying IPO closing occurs inside the window at all — an independent path to No regardless of any future share-structure decision.
BOTTOM LINE: Every fresh September–October 2026 data point reinforces, rather than undercuts, the structural status quo: OpenAI is substituting a $30B private round at ~$1.4T for a near-term IPO, Altman continues to hold zero personal equity, the sole super-voting instrument (Class N) remains institutionally held by the nonprofit Foundation with no disclosed plan to change that, and the confidential S-1 has sat without amendment for four-plus months — all of which argue for No both on substance (no super-voting mechanism for Altman exists or is proposed) and on timing (IPO closing, the trigger event, is being actively deferred).
NOT FOUND: No public S-1 text or any report describing a contemplated share-class/voting structure for the eventual OpenAI IPO; no confirmed IPO date; no report since 2024 of any renewed proposal to grant Altman personal equity of any kind, super-voting or otherwise.

(a) About 15 months remain to the 2028-01-01 close, possibly less if the 'one year after issuance' clause sets expiration around late September 2027; OpenAI must both complete an IPO and give Altman a personal high-vote share class before initial closing. (b) Status quo: multiple 2025-2026 sources, including May 2026 court filings, say Altman holds zero OpenAI equity; the only super-voting instrument (Class N) belongs to the nonprofit Foundation; the IPO is being deferred, with Altman calling 2026 'ill-advised', a $30B+ private bridge round at ~$1.4T, and CFO readiness doubts. Nothing changing means No. (c) NO: the IPO slips past the window, or it closes with Foundation Class N control and Altman holding no personal high-vote stock. (d) YES: OpenAI lists in 2027 and the board revives the shelved 2024 equity discussion, granting Altman a founder high-vote class mirroring Anthropic's reported 50.1% co-founder voting bloc. I put P(IPO closes in window) at ~40-50% and P(personal super-voting grant | IPO) at ~20-25%, giving ~10%, nudged slightly up for confidential-S-1 unknowns. The Kalshi anchor is 31%, already falling from 41-47%, and I see no evidence supporting that level.

(0) Not resolved. EDGAR shows no public OpenAI S-1; the June 2026 draft remains confidential. Multiple 2026 sources, including May 2026 court filings, report that Altman holds zero OpenAI equity. Two things must still happen: a qualifying IPO must close before the window ends, and Altman must hold a personal high-vote class at that closing.
(a) About 15 months remain until the 2028-01-01 close. Altman says the IPO is not in 2026, and OpenAI is raising a ~$30B private bridge round at ~$1.4T instead. I put the chance of an IPO closing in 2027 at roughly 40-50%.
(b) Status quo is No. Control runs through the nonprofit Foundation's Class N share, not personal founder stock, and Altman owns nothing.
(c) NO scenario: the IPO slips past 2027. Or it lists with the Foundation's Class N as the only high-vote instrument, and Altman holds nothing or only ordinary common or unvested RSUs.
(d) YES scenario: before the IPO, the board revives the frozen equity-compensation discussion. It grants Altman a founder super-voting class, mirroring Anthropic's reported 50.1% co-founder voting bloc, and OpenAI lists in 2027.
A personal super-voting grant would clash with the nonprofit-control structure the Delaware AG approved. That makes it unlikely even if he gets equity; I put it at about 20-30% conditional on an IPO.
The Kalshi anchor is 31%, already down from 41-47%. I see no specific information supporting that level and price combined odds of roughly 10-15%.

Neither outcome is already established: the SEC search found no public OpenAI S-1, but that does not exclude the reported June 8 confidential submission, and no source documents an IPO closing or qualifying Altman holding. The rules impose expiration at the earlier of 14 days after IPO trading begins or one year after issuance, implying approximately late September 2027—about 12 months remaining if issuance coincided with opening—rather than the displayed January 2028 trading close. I anchor on Kalshi's live 31% YES price and reduce it to 24%, principally because that tighter contractual deadline and the September 29 Quartz report of private bridge financing instead of an imminent IPO suggest potentially underpriced timing risk. The status quo favors NO: October 2025 restructuring coverage and September 2026 reports citing May court filings say Altman holds no direct equity, while the Foundation's Class N board-appointment powers establish neither his beneficial ownership nor qualifying higher votes per share. A NO scenario is an IPO with that ownership structure unchanged, no qualifying closing before expiration, or no permitted source documenting a qualifying holding; Altman's September 12 Fortune comments favoring 2027 and the reported bridge financing support the delay pathway. YES requires a timely SEC-registered IPO plus an actual, settled holding for Altman, directly or beneficially, carrying more votes per common-share-equivalent than public investors receive at initial closing, documented by an allowed source before expiration with SEC filings taking priority. The historical equity-compensation discussions and reported Anthropic founder-voting structure provide a plausible route to YES, but neither establishes an OpenAI grant, and special board-election rights alone explicitly do not qualify. I retain substantial YES probability and only moderate confidence because the draft filing is unavailable, direct-equity reports do not exhaust beneficial-ownership possibilities, several governance claims rely on secondary trackers, and the issuance-date discrepancy leaves meaningful deadline uncertainty.

Neither outcome is established: the SEC EDGAR search found no public OpenAI S-1, which is compatible with the reported confidential June 8 submission, but no supplied source documents an IPO closing or qualifying Altman ownership. The rules allow roughly 12 months remaining—approximately September 30, 2027, or 362 days, if issuance coincided with opening—with potentially earlier expiration 14 days after first trading; the January 2028 trading close does not override the one-year limit. I anchor on Kalshi's live 31% Yes and adjust to 23%, principally for two potentially underweighted contractual distinctions: the shorter deadline and the exclusion of board-election rights that some research incorrectly treats as qualifying super-votes. If nothing changes, No wins: Transformer’s October 28, 2025 restructuring report says Altman took no equity, September 2026 secondary reporting reiterates zero direct equity, and control remains with the Foundation. Altman's Foundation directorship does not itself establish beneficial ownership of its shares or greater common-share-equivalent votes per share. A concrete No scenario is an IPO without a personal high-vote holding, or no qualifying IPO before expiration, with delay supported by Altman's September 12 Fortune comments and Quartz's September 29 report of a proposed $30 billion private bridge round. Yes requires a timely SEC-registered IPO and an actual direct or beneficial high-vote holding at initial closing, potentially through renewed founder-compensation negotiations and adoption of a peer-style dual-class structure, rather than merely an announcement or unexercised option. Confidence is limited because final ownership and voting terms remain confidential, peer precedents are weakly sourced, and qualifying ownership must be reported by an accepted source before expiration even if it exists in reality.

(0) The condition is not already met: the SEC EDGAR resolution-source search shows no public OpenAI S-1 or completed IPO, while reports of a confidential draft filing disclose neither share classes nor an Altman holding. (a) Roughly 12-15 months remain, depending on whether the operative outer deadline is one year after contract issuance in late September 2027 or the supplied January 1, 2028 close time; a qualifying IPO must close before the applicable expiration. (b) If nothing changes, the outcome is No because Altman currently holds no reported OpenAI equity, the Foundation—not Altman—holds the controlling Class N instrument, and no IPO by expiration also resolves No. (c) A straightforward No scenario is that the reported $30 billion private bridge round delays the IPO beyond expiration, or that an IPO occurs with the Foundation retaining its special governance rights while Altman receives no high-vote shares. (d) Yes requires the board to grant Altman beneficial ownership of a higher-vote class before the IPO's initial closing, potentially following Anthropic's founder-control precedent, and for that holding to appear in the priority SEC filings. Kalshi's current Yes price is 31%, but I move below it because the company-specific evidence is unusually adverse to personal founder super-voting ownership: repeated zero-equity reporting, a shelved prior grant, institutional rather than personal control, and fresh IPO deferral, though the confidential filing and unresolved final structure preserve meaningful upside.
