GPT-5.6 released by July 7, 2026?

What is happening now

The Polymarket event “GPT-5.6 released by…?” tracks whether OpenAI will make its next-generation model publicly available by specific dates. As of July 5, 2026, GPT-5.6 remains unavailable to the general public despite entering a limited preview on June 26, 2026. That preview was restricted to approximately 20 government-approved partner organizations under a safety review process requested by the White House, explicitly not qualifying as public access under market rules.

OpenAI’s official position states the model will reach general availability “in the coming weeks” following the preview period. The company has not announced a specific public release date, leaving the timeline uncertain beyond the government-gated rollout.

How the market is structured

This is a date ladder consisting of 20 separate binary markets, each asking whether GPT-5.6 will be publicly released by a specific deadline. Markets are grouped under one event but resolve independently. Each market offers Yes/No outcomes with prices representing the crowd-sourced probability of public availability by that date.

Ten markets have already closed in the “No” direction as dates passed without public release. Ten active markets remain, with the following key probabilities:

• July 6: 99.1% No (resolves tomorrow)
• July 7: 94% No
• July 8: 86% No
• July 9: 68.5% Yes
• July 10: 73.5% Yes
• July 13: 80.5% Yes
• July 15: 84.5% Yes
• July 17: 90.8% Yes
• July 24: 93.2% Yes
• July 31: 97.7% Yes (current leading outcome)

Path to the leading outcome

For the July 31 market to resolve “Yes” at 97.7%, OpenAI must make GPT-5.6 publicly accessible by that date. This requires either:

• An explicit public announcement with open signup or open beta access
• Public availability through ChatGPT or API without invitation restrictions
• Clear labeling on OpenAI’s website indicating general-public availability

The model cannot resolve “Yes” through the current government-vetted partner preview, which the contract explicitly excludes as “closed and private access.” Any release must be genuinely open, not gated by federal approval or limited to pre-approved organizations.

What could change the pricing

Several developments could shift market probabilities:

• Early public release: An announcement before July 9 would boost earlier markets while potentially capping later ones if the model launches sooner than expected
• Delayed rollout: Official communication pushing general availability beyond July 31 would drive the leading market toward “No”
• Government extension: If the preview period extends longer than anticipated, it would reinforce “No” pricing across near-term markets
• Technical issues: Problems during the preview phase could delay public availability, affecting mid-July markets most directly
• Regulatory changes: New government requirements or modified oversight could push release dates further out

The July 6 market resolves tomorrow at 99.1% No, providing an immediate data point. If that resolves as expected, attention will shift to July 7-8 markets, where “No” probabilities of 86-94% suggest traders expect at least another week before public availability.

Editorial read

The market reflects a fundamental tension between OpenAI’s stated timeline and the reality of government-mandated oversight. Traders have priced in approximately two weeks of continued restricted access following the June 26 preview, with the probability curve steepening significantly after July 8.

Total volume of $2.78 million across all markets indicates substantial engagement, though liquidity varies considerably. The July 31 market holds $285K in liquidity with 97.7% probability, suggesting strong consensus around a late-July public release. However, this pricing assumes the government review process concludes as described and doesn’t become a recurring bottleneck.

The critical risk factor is whether the current preview structure represents a one-time accommodation or a new standard for frontier AI releases. OpenAI has indicated the gated approach isn’t their preferred long-term model, but regulatory pressure could extend similar restrictions to future model launches, making the “in the coming weeks” timeline less certain than current pricing implies.

With the July 6 market resolving imminently and no public release yet announced, the next 48 hours represent a key inflection point. A “No” resolution there would likely push July 7-8 markets even further toward certainty, while maintaining the steep probability curve that currently favors mid-to-late July for actual public availability.
