Pronóstico: GPT-5.6 released on 2026?

Platform comparison

Market context

OpenAI has announced the GPT-5.6 family on 26 June 2026, yet the model remains a limited preview for trusted partners via the API and Codex, with no general-availability date confirmed. The current crowd-implied probability of 0% YES on the Polymarket contract reflects this reality: the settlement window ends 31 July 2026, and while internal targets point to a 7–9 July rollout, full public access is still contingent on US regulatory approval. Historical precedents show that OpenAI often delays broad releases after government intervention, as seen with earlier flagship models where limited previews lasted weeks before wider access.

Traders should monitor announcements from OpenAI’s Deployment Safety Hub and updates from the US government regarding cybersecurity frameworks for AI models. Recent reports indicate OpenAI expects to expand access to more companies next week, but full rollout to ChatGPT users remains unconfirmed. A key catalyst is the removal of Anthropic’s Claude Fable 5 from subscription packages on 7 July, which may pressure OpenAI to accelerate its own release. However, as of 7 July, the July window appears to be an expansion to enterprise users rather than a full-scale public launch.

The on-chain mechanics of this Polymarket contract—settled in USDC on Polygon using conditional tokens—mean that any delay beyond 31 July will resolve the market as NO. With Polymarket prices previously showing a 68–74.5% probability for a 7 July release, the shift to 0% suggests growing scepticism about timely public access. Until OpenAI officially confirms a general-availability date, the market remains firmly in the NO zone.

FAQ

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

Do I need to KYC for this market?

On Polymarket directly, no — it's wallet-based. Intermediary brokers like Polymarket Qué Es trigger KYC only above $1,500 of lifetime trading volume; under that you trade pseudonymously with a single wallet address.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
