Sub-questions (Fermi decomposition)

What is the current NPM Price / implied valuation for OpenAI shown on the Nasdaq Private Market page, and what is its recent trajectory?
What valuation is OpenAI's most recent or in-progress funding round / tender offer being priced at (e.g., $500B Oct 2025 secondary; reported $750B-$830B+ talks), and when will it close?
Is OpenAI planning an IPO or direct listing before December 31, 2026, and what valuation range ($1T+?) is being reported for it?
How does the NPM Price methodology work (secondary trade prices, fund marks, round pricing) and how quickly does it reflect new round valuations?
What are OpenAI's revenue run-rate and growth (2025 ~$13B, 2026 projections) and what revenue multiple would a $2T valuation imply relative to comparable AI/tech companies?
What do sibling Polymarket markets ($1T, $1.5T, etc.) and Kalshi OpenAI valuation/IPO markets imply about the probability distribution?

Planner reasoning

This is a Polymarket question on whether OpenAI's NPM Price-implied valuation reaches $2.0T by end of 2026. OpenAI was last valued around $500B (Oct 2025 secondary) with reports of fundraising talks at $750B-$830B+, so hitting $2T requires roughly a 2.5-4x jump within a year, most plausibly via an IPO. Key drivers are the current NPM print, the pace of primary/secondary rounds, IPO timing/valuation reports, and how NPM computes its price (secondary trades vs. round pricing).

# Event Will OpenAI's private/public market valuation reach or exceed $2.0T (as measured by Nasdaq Private Market's NPM Price, or post-IPO market cap) at any point before December 31, 2026? # Outcomes to forecast - Yes (valuation hits ≥$2.0T by Dec 31, 2026) - No (valuation stays below $2.0T through period) # Kalshi market anchor No kalshi_direct price was returned in this research pull (tool did not appear in raw output) — this is a gap. Best available cross-market proxy: **Polymarket "Will OpenAI's valuation hit (HIGH) $2.0T by December 31?" = 10.5% YES**, down 2.5pts over 7 days, flat over 30 days, range 6.5%-19.5% over 90 days, volume ~$142K. Treat this as the working consensus anchor in absence of direct Kalshi data. # Resolution source Fetched https://fe.secondmarket.com/companies/company-30839e0b-2730-4495-839f-1bf638fa9cca/data (NPM's official page) — page returned only the site name with no renderable valuation data (likely JS-gated). Cannot confirm current NPM Price from this fetch directly, but claude_news independently reports NPM's public-facing page (nasdaqprivatemarket.com/company/open-ai) showed **$733.97/share NPM Price as of ~Sep 4, 2026**, implying a valuation far below $2.0T (comparable Forge Price $721.85 on 9/19/2026; Yahoo Finance estimate ~$965B). Resolution condition is clearly NOT met as of latest available snapshot. # Sub-question answers 1. **Current NPM Price/trajectory** — NPM Price ~$733.97/share (~Sep 4, 2026), implying valuation well under $1T-$965B range per Yahoo Finance/Forge cross-checks [claude_news]. No NPM data confirms anything near $2T. 2. **Latest/in-progress round** — Confirmed: $122B round closed March 2026 at $852B post-money [Wikipedia, CNBC]. In-progress talks (Sept 2026): investors floated a $1.2T valuation for a new round; OpenAI not formally engaged as of mid-Sept [CNBC, Bloomberg]. $6.6B tender at $500B (Oct 2025) and $7B secondary sale (Aug 2026) also occurred [CNBC]. 3. **IPO plans** — Altman has ruled out a 2026 IPO citing AI-safety concerns; CFO Sarah Friar reportedly guiding toward a 2027 debut [claude_news/NYT via Benzinga]. Altman reportedly called any IPO valuation below $1T a "non-starter" — far below $2.0T threshold. No 2026 listing expected, reducing paths to hit $2T via public markets within this window. 4. **NPM methodology** — NPM Price is a proprietary daily estimate based on secondary trade activity, publicly-sourced valuation data, and other inputs [Wikipedia/tool description]; it updates daily (1pm ET next day) but tends to track secondary market pricing/fund marks rather than instantly jumping to headline primary round valuations — historically lags formal round announcements by weeks/months. 5. **Revenue/multiples** — Revenue run-rate ~$20B+ end-2025, >$40B annualized by Aug 2026 (~2x YoY) [Bloomberg/CNBC]. $2.0T valuation on ~$40-50B revenue implies ~40-50x revenue multiple — aggressive even vs. current ~20x ($852B/$40B) multiple; cash burn ~$27B (2026) and $63B (2027 est.) adds risk discount. 6. **Sibling markets** — Polymarket "$1T+ valuation in 2026" trades at 69.6% YES; "highest IPO market cap 2026 — OpenAI" only 0.6% (no 2026 IPO expected); Kalshi "OpenAI or Anthropic IPO first — Anthropic" at 94%. These imply markets see $1T as plausible but $2T/2026-IPO as very unlikely. # Key facts (high-confidence, factual) 1. [CNBC/Wikipedia] Last confirmed round: $852B post-money, March 2026. 2. [claude_news] Current NPM Price ≈$734/share (~Sep 2026), Forge Price ≈$722; both imply valuation well under $1T. 3. [Bloomberg/Benzinga] New funding talks (Sept 2026) discuss $1.2T valuation — still 40% below $2.0T target. 4. [claude_news/NYT] Sam Altman ruled out 2026 IPO; 2027 debut more likely per CFO guidance. 5. [Bloomberg] Revenue run-rate >$40B annualized by Aug 2026. # Cross-market signals - Polymarket (same question): 10.5% YES, downtrend. - Polymarket "$1T+ by 2026": 69.6% YES — shows market believes $1T achievable but doesn't extend confidence to $2T. - Polymarket "highest 2026 IPO cap — OpenAI": 0.6% — market assigns near-zero chance of an OpenAI IPO happening/dominating in 2026. - Kalshi related "OpenAI or Anthropic IPO first — Anthropic": 94% — reinforces no near-term OpenAI IPO. - No sportsbook signals applicable. # Analyst opinions and speculation - Bloomberg/CNBC reporting frames $1.2T as the most aggressive currently-discussed private valuation talk — still speculative, not closed. - Code-execution Monte Carlo model (trend + volatility extrapolation) estimates ~18-30% probability of touching $2.0T intra-period by Dec 31, 2026, requiring sustained 175-230% annualized valuation growth — a historically extreme but not unprecedented pace given 2024-25 trajectory, though deceleration signals are emerging. - Altman reportedly treats <$1T as a "non-starter" floor for any IPO — implicitly, market commentary treats $2T as aspirational multi-year target, not 2026-imminent. # Directional lean per outcome - **Yes**: Requires >2.7x jump from current ~$734/share NPM implied value (or from $852B/$1.2T talk-stage) within ~3 months of resolution window; no IPO before 2026 close (ruling out big public repricing); historical growth pace has been triple-digit % annualized, so not impossible, but no confirmed pathway or round currently priced near $2T. - **No**: Current NPM/Forge marks near $722-734/share level; most aggressive reported talks cap near $1.2T; IPO pushed to 2027; revenue multiple implied by $2T (~40-50x run-rate revenue) exceeds current ~20x; Polymarket and sibling IPO markets consistent with low probability. # Gaps / unknowns - No confirmed Kalshi YES price captured in this research pull (tool absent) — must be reconciled against live Kalshi order book before finalizing. - NPM resolution page itself returned no visible data (JS-rendering issue); relying on secondary reporting of NPM Price snapshot. - Whether the rumored $1.2T round closes, and at what final valuation, remains unresolved as of research date (mid-Sept 2026). # Calibration anchors - Polymarket YES price for identical event: 10.5% (proxy anchor, since Kalshi direct unavailable). - Sibling Polymarket "$1T by 2026": 69.6% — implies steep drop-off in probability mass between $1T and $2T buckets. - Monte Carlo/trend-based fair-value estimate: ~18-30%, moderately above the Polymarket price, suggesting Polymarket may be somewhat underpriced but still consistent with low-probability "No" lean.

The resolution source (NPM Price) sat at ~$734/share in Sep 2026, implying a valuation under $1T, and the last closed round was $852B (Mar 2026) with the most aggressive reported new-round talk at only $1.2T — 40% below the $2.0T threshold. Altman has ruled out a 2026 IPO, eliminating the public-market repricing path, and NPM Price historically lags primary-round headlines by weeks/months, so even a surprise $2T round would need to close early enough to be reflected before Dec 31. The sibling Polymarket '$1T by 2026' at ~70% versus this identical-event market at 10.5% shows a steep probability drop-off between $1T and $2T; the trend-extrapolation Monte Carlo (18-30%) ignores the deceleration and the resolution-source lag. I anchor on the Polymarket 10.5% proxy and shade slightly lower given no confirmed pathway near $2T within ~3 months.

The resolution source (NPM Price) sits at roughly $734/share as of early Sept 2026, implying a valuation well under $1T and requiring a ~2.7x repricing in about 3.5 months; NPM Price historically lags primary-round headlines rather than jumping to them. The most aggressive reported talks are for a $1.2T round that OpenAI has not even formally engaged in, Altman has ruled out a 2026 IPO (eliminating the public-market repricing path), and a $2T mark would imply a ~40-50x revenue multiple versus the current ~20x. The Polymarket proxy for the identical question is 10.5% and trending down, with sibling markets (69.6% for $1T, 0.6% for a 2026 OpenAI IPO) consistent with a steep probability drop-off above $1T. The trend-extrapolation Monte Carlo (18-30%) ignores the NPM lag and the absence of any concrete $2T pathway, so I shade modestly below the Polymarket price.

The resolution source (NPM Price) sits at ~$734/share as of Sep 2026, implying a valuation under ~$1T, and the most aggressive live funding talks are only at $1.2T — 40% short of the $2.0T threshold. Altman has ruled out a 2026 IPO, removing the main path to a sudden public-market repricing, and NPM Price historically lags primary-round headlines, so even a surprise $2T round late in the year might not register in NPM's daily estimate before Dec 31. Polymarket prices the identical question at 10.5% YES and trending down, while sibling markets ($1T at ~70%, OpenAI 2026 IPO near 0%) confirm a steep probability drop-off between $1T and $2T. A $2T valuation would imply ~40-50x run-rate revenue versus ~20x today, which is aggressive given $27B+ cash burn; I shade slightly below the Polymarket anchor given the NPM lag and short remaining window.

Yes	10%
No	90%

The 10.5% Polymarket YES price is the best available consensus anchor because no direct Kalshi price was retrieved. Current NPM and Forge pricing implies a valuation below roughly $1T, while the most aggressive reported financing talks concern only $1.2T, pointing strongly toward No with roughly three months remaining. A 2026 IPO has reportedly been ruled out, removing the clearest mechanism for a rapid repricing, while $2T would require an aggressive 40-50x revenue multiple despite substantial cash burn. I place YES slightly below the proxy anchor because NPM may lag headline rounds and no transaction near $2T is currently reported, though OpenAI's exceptional historical growth preserves a meaningful tail chance.

Yes	10%
No	90%

The best available consensus anchor is Polymarket’s 10.5% YES price, as no direct Kalshi price was retrieved. Current NPM and Forge prices imply a valuation below roughly $1T, while the most aggressive reported funding talks contemplate only $1.2T, so reaching $2T within about three months would require an extraordinary repricing. A 2026 IPO has reportedly been ruled out, removing the clearest mechanism for a rapid public-market revaluation, and $2T would imply an aggressive 40–50x revenue multiple. I therefore stay close to the market anchor and discount the higher trend-extrapolation estimates, while retaining some YES probability because OpenAI’s valuation has previously grown unusually quickly and NPM can react to private transactions.
