OpenAI, 1455 3rd St, San Francisco, CA

OpenAI

开始于 2027/02/28预估可信度 67%A "by when" market with no scheduled event behind it. February 2027 carries the largest month-on-month jump among the rungs below that block — 12% before February 1 rising to 39% before March 1, 27 points — and a month-only date takes its last day. The April strike (70%) is quoted above both May (49%) and June (61%), so the top of the ladder is out of order and was not used. All figures are the chance the strike list shows, not the Yes price in cents.^[1]

Kalshi

On 20 September 2026 Kalshi put an official OpenAI IPO announcement at 5% before January 2027, 12% before February and 39% before March — a 27-point jump across February. The upper rungs did not run in order: the page showed 70% before April, then 49% before May and 61% before June.
