67% — When will OpenAI IPO
Leader: Before Jun 1, 2027 at 67% · Kalshi 67% · 9 contracts · $2K volume · medium confidence
Updated 2026-07-24 01:59:40 UTC

Tracks the leading outcome in a winner-take-all prediction market set with 9 outcomes.

Why this matters:
Markets currently assess a 67% likelihood that OpenAI will complete an initial public offering before June 1, 2027. This probability reflects uncertainty around OpenAI's strategic timeline and regulatory environment. The market is pricing in a meaningful but not overwhelming chance of a near-term listing, with higher confidence in a pre-June deadline than a pre-February one (59% vs 32%). The main factors driving this estimate are OpenAI's financial performance, management statements about going public, and the broader regulatory climate for AI companies. Any official announcement or regulatory guidance about IPO timing would significantly alter these prices. Notably, the probability drops sharply for dates before October 2026, suggesting markets view that window as unlikely but not impossible.

Key factors:
- OpenAI has not publicly committed to an IPO timeline; any official statement would directly impact contract prices
- Market assigns 67% probability to a June 2027 deadline but only 6% to an October 2026 deadline, indicating skepticism about imminent listing
- The 59% price on a May 2027 contract versus 67% on June 2027 suggests traders expect resolution clarity closer to summer 2027
- Regulatory approval and SEC review processes would be critical path items; changes to AI regulation or OpenAI's compliance status could shift probabilities materially
- Private valuation trends and OpenAI's capital needs relative to its cash position would influence management's incentive to pursue public markets

## Methodology

SimpleFunctions aggregates live YES-side prices from Kalshi and Polymarket contracts bound to this question. For binary topics the headline is the liquidity-weighted mid-price (weight = log(1 + 24h volume) × freshness, where freshness is 1.0 if updated <24h, 0.7 if <7d, 0.4 otherwise). For multi-outcome (winner-take-all) topics the headline is the current leader's price — disjoint outcomes are never arithmetically averaged. Snapshots refresh every 5 minutes during market hours.
