# Current state
OpenAI completed its restructuring into a Delaware public-benefit corporation (Oct 2025) and confidentially filed for an IPO in mid-2026, but has not yet gone public as of the latest data (Aug 2026). CFO Sarah Friar is now targeting a 2027 listing (having slipped from earlier 2026 chatter) at a target valuation "up to $1 trillion" — this is a stated ambition, not a locked resolution outcome; the market requires an actual IPO by Dec 31, 2027 AND a first-day closing cap >$1T.

# Event
Will OpenAI's IPO-day closing market capitalization exceed $1 trillion (resolves No if no IPO by Dec 31, 2027)?
# Outcomes to forecast
Yes / No
# Kalshi market anchor
No distinct Kalshi-direct feed was returned for this ticker; the only direct order-book data available is from Polymarket on this identical market: **YES currently ~75.5%**, up from a 90-day low of 69% (30-day trend +3.5%, 7-day flat), volume ~$1.05M. Treat this as the primary consensus anchor in absence of Kalshi-specific pricing.
# Sub-question answers
1. **P(IPO by Dec 2027)** — Confidential S-1 filed (mid-2026); CFO targets 2027; but CNBC reports the timeline slipping from 2026 to 2027 amid market jitters post-SpaceX IPO. No explicit probability given by sources; consensus market (Polymarket) implicitly embeds a high joint probability via the 75.5% price.
2. **Latest valuation & growth needed** — $852B as of Apr/Aug 2026 (post $122B round + $7B buyback). To clear $1T pre-IPO needs only ~17-20% further growth, achievable within a year at OpenAI's recent pace (Wikipedia/ibtimes).
3. **Executive statements** — Altman rejected lowering the $1T target for a faster listing; Friar reaffirmed 2027 timeline and downplayed racing Anthropic to IPO (Forbes, Fool, freepressjournal).
4. **Historical IPO pop base rate** — n=13 mega-IPOs (Alibaba, Aramco, ARM, Facebook, etc.): mean first-day pop +30.5%, median +10%, only 15.4% popped ≥100%; pop alone rarely bridges a large valuation gap — sustained pre-IPO valuation growth is the dominant lever (code_execution analysis).
5. **Related markets** — Same Polymarket market at 75.5% YES. Kalshi related market "OpenAI or Anthropic IPO first" shows Anthropic favored at 93% (up from 71%), implying market expects Anthropic to list before OpenAI, indicating possible timeline risk for OpenAI's own IPO. No Kalshi valuation-ladder market for OpenAI found.
6. **Macro/AI valuation trend** — Sector extremely bullish: Anthropic reportedly eyeing a $2T IPO; Nvidia/Microsoft/Amazon making massive AI infrastructure commitments; but skepticism exists (Ed Zitron pieces, SpaceX's post-IPO price decline, OpenAI's large operating losses) suggesting bubble-repricing risk.

3. [Leaked financials via news] 2025 booked revenue $13.1B vs. operating loss $20.9B.
4. [CNBC/Quartz] OpenAI reportedly leaning toward 2027 rather than 2026 listing.

# Cross-market signals
- Kalshi related: "OpenAI or Anthropic IPO first" favors Anthropic (93%), suggesting timing risk for OpenAI relative to peers.
- Polymarket: This exact market trading at 75.5% YES, modest uptrend.
- Sportsbook implied: N/A.
# Analyst opinions and speculation
- FutureSearch quant model: central estimate IPO ~mid-2027, projected 90-day post-IPO cap ~$1.2T (bullish).
- Skeptics (Ed Zitron): question OpenAI's financial sustainability given massive losses.
- Advisers reportedly cautious post-SpaceX's volatile IPO debut, favoring delay over rushed mega-listing.
# Directional lean per outcome
- **Yes**: Strong revenue growth (~$40B run-rate), rapid valuation escalation ($500B→$852B in ~1yr), Altman's firm $1T target, confidential filing already underway, bullish AI sector comps (Anthropic targeting $2T) support hitting $1T handily if IPO occurs on schedule.
- **No**: Heavy operating losses, IPO timeline repeatedly slipping (2026→2027), macro caution post-SpaceX's rocky debut, execution/regulatory restructuring risk (California/SEC scrutiny), and historical base rate showing IPO-day pops are usually modest (median +10%) — closing >$1T requires both timely IPO execution and valuation holding up, a conjunction of uncertain events.
# Gaps / unknowns
- No confirmed exact IPO date, share count, or float size.
- Code-model P(IPO by 2027) estimates (15-40%) appear conservative vs. Polymarket's 75.5%, unclear reconciliation — possible market is also pricing in a longer runway/optimism about eventual completion beyond nominal caution in single quant model.
- No genuine Kalshi order book price returned for this specific ticker.
# Calibration anchors
- Polymarket YES price (proxy anchor): 75.5%, trending up over 30 days.
- Quant model (FutureSearch) blended estimate: P(YES) ≈ 13-21% under conservative assumptions — a significant divergence from market price, suggesting real uncertainty in specific probability estimation methods.
- Historical base rate: only ~15% of mega-IPOs pop ≥100% on debut day; valuation growth pre-IPO (not the pop) is the key lever.
