When will GPT-5.6 be released?

Market context

OpenAI’s next model release is the real-world event that matters here: whether a product explicitly called GPT-5.6 becomes generally available before the market closes on 28 June 2026. The crowd is pricing a near-certainty the other way, which only makes sense if traders think the naming, launch channel, or timing will slip beyond the settlement window rather than if the model is absent altogether.[1][7]

The useful historical frame is OpenAI’s recent compression in release cadence. GPT-5.1 arrived in November 2025, GPT-5.2 in December 2025, GPT-5.4 in March 2026 and GPT-5.5 on 23 April 2026, so a late-June follow-up would fit a roughly six-week rhythm rather than a traditional quarterly cycle.[3][7] That sequence matters because this market does not care about a new flagship label in general; it resolves only if OpenAI uses the GPT-5.6 designation, or a clearly recognised direct successor such as GPT-5.7 or GPT-5.8, for public availability.[2]

Catalysts are likely to be product notes, API model listings, and any ChatGPT rollout announcement, especially if OpenAI repeats the pattern seen around GPT-5.5, when release notes updated first and the broader rollout followed quickly.[7] Secondary signals include backend routing logs and Codex references, which have already been cited as evidence that GPT-5.6 was in testing before any formal launch post.[1][4] If OpenAI chooses to package the release as a task-specific or cost-efficient variant, that would still count under the market rules, but a fresh flagship name would not.[2]

Methodology

We track When will GPT-5.6 be released? on the five venues with material liquidity for prediction markets. Live odds come from the Polymarket Polygon order book — the only source that ships real-time data under an open licence. For Kalshi, Betfair and Manifold we list platform attributes (fee, KYC, settlement, payment) instead of fabricated odds, because their APIs use non-comparable contract definitions.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
