GPT-6 release date odds: what prediction markets say

By TomorrowAlpha Editorial Desk · Published · Updated

Short answer

OpenAI began rolling out GPT-6 Astra on 3 September 2026 to approved business users in its Daybreak program, with a version for paid ChatGPT users announced. Whether prediction markets resolve YES depends on their wording: Polymarket's 2026 market requires general public availability, so a closed or invitation-only rollout does not count.

Has GPT-6 been released?

Partially. On 3 September 2026 OpenAI said it had rolled out GPT-6 Astra to business users in its Daybreak program and planned a version with extra cybersecurity guardrails for paid ChatGPT users. Before that, OpenAI's newest public family was GPT-5.6 (July 2026).

How Polymarket and Kalshi decide if GPT-6 is 'released'

Polymarket's 'GPT-6 released by December 31, 2026' market resolves YES only if a model explicitly named GPT-6 (or a recognised GPT-5 successor) is available to the general public, including open beta or an open rolling waitlist. Closed betas and private access do not count, and 'GPT-5.5'-style names don't qualify. Kalshi's monthly contracts use their own rule text — always read it on the market page.

This is why GPT-6 odds can stay below 100% even after an announcement: traders are pricing whether the rollout meets the public-availability test before the deadline.
