The prediction market Polymarket shows a 45% chance that OpenAI's GPT-5.6 will be released by the end of June 2026, with $202,000 in total volume wagered on the outcome. The probability, hovering just below 50%, indicates that traders see the release as a coin flip, with no clear consensus on timing. This contrasts with the typical pattern for AI model launches, where markets often show higher confidence in near-term releases. The absence of data from other major platforms like Kalshi and Manifold limits cross-market comparison, but Polymarket's liquidity suggests active interest in the event. No specific external trigger, such as OpenAI announcements or industry reports, was identified in today's news flow to explain the current probability level. The 45% figure implies that traders are pricing in a roughly equal chance of the release occurring before or after the deadline, possibly reflecting uncertainty over OpenAI's development pace and potential regulatory or technical hurdles.
