GPT-5.6 released on 2026?

Platform comparison

Market context

OpenAI has confirmed a limited preview of GPT-5.6 Sol, Terra and Luna began on 26 June 2026, with general availability to the public expected within weeks, though no fixed date has been announced. The U.S. government requested this delayed rollout, restricting initial access to a small group of vetted partners whose details were shared with authorities, before broader release through ChatGPT, Codex and the API.

Historical release patterns within the GPT-5 generation show a consistent six-week cadence between flagship models: GPT-5.4 on 5 March, GPT-5.5 on 23 April, and GPT-5.6 now surfacing in late June. This rapid iteration, coupled with internal routing logs already showing GPT-5.6 before any official announcement, frames the current 0% crowd-implied probability as misaligned with observable development momentum and pre-launch consensus signals from Polymarket, which priced the 22–28 June window at 83–89% probability.

Traders should monitor OpenAI’s official communications for a general-availability date, track updates in Codex backend logs where version bumps typically appear first, and watch for the simultaneous release of the GPT-5.6 system card and deployment safety hub entry. As reported by Reuters, the delay was government-driven, not technical, meaning the path to public release remains clear once regulatory engagement concludes. The next catalyst will likely be an announcement confirming expanded access beyond the current limited preview group.

FAQ

Are prediction markets better than sports betting?

Prediction markets tend toward tighter odds than bookmakers because they use peer-to-peer exchange rather than bookmaker margin. On major matches, Polymarket quotes typically sit 2-5% closer to the true probability model than bet365 or DraftKings.

What are live sports odds on Polymarket?

Some top-tier matches stay open during play — you can trade the half-time probability in the 70th minute. Polymarket mid-prices update second-by-second; any frontend mirroring the order book shows the same movement.

Which sports markets are available?

Football (soccer) dominates — Champions League, World Cup, Premier League, La Liga, Bundesliga — followed by NFL, NBA, tennis Grand Slams, Formula 1, boxing/MMA. Resolution via official league source confirmation.

How fast do sports winnings settle?

Once the official league outcome is logged in the UMA Oracle (typically 1-2 hours after the final whistle), Polymarket's smart contract triggers USDC payout. To your wallet within minutes.

Can I import form data and lineups?

This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
