Polymarket traders price GPT-6 at 71.5% odds by Sept 30

Bettors on the prediction market give GPT-6 a 71.5% chance of launching by Sept. 30, down from 73.5% a day earlier, as Altman heads to Washington.

Polymarket traders are betting GPT-6 arrives this autumn, pricing a 71.5% chance the model ships by Sept. 30, 2026, and an 88.5% chance by Dec. 31. The “GPT-6 released by” event has become one of the platform’s most-watched AI contracts.

The most-traded deadline saw its YES token ease from 73.5c to 71.5c over the past 24 hours, the only deadline among the event’s contracts to register a clear move. A July 31 launch is treated as a long shot at roughly 1% (0.75c), while early-August contracts sit in the low single digits (Aug 7 ~1.5%, Aug 14 ~9%) before climbing into the low-teens-to-mid-20s by late August (Aug 21 13.5c, Aug 31 25.5c). The market spans seven separate release-date contracts, from a July 31 window to year-end.

The odds land as OpenAI CEO Sam Altman returns to Washington this week to brief Trump administration officials and lawmakers on the company’s latest advanced model, with a voluntary AI review framework set to close on Aug. 1.

What the GPT-6 Polymarket odds say

The “GPT-6 released by” event has drawn about $750,800 in total volume on Polymarket, with roughly $24,000 changing hands in the last 24 hours. The Sept. 30 deadline is the most active open contract, reflecting where traders expect the next flagship release to land.

Beyond the autumn target, bettors put an 88.5% probability on a 2026 year-end launch and just 1% on anything before August. The pricing curve points to a late-summer or early-fall debut rather than an imminent release, with the market treating near-term deadlines as increasingly unlikely. Traders are effectively rewarding patience: the further out the deadline, the higher the price, a pattern consistent with expectations that OpenAI will iterate through GPT-5.x refreshes before a true generational jump.

OpenAI has not confirmed a GPT-6 timeline. The company said in October 2025 that GPT-6 would not ship that year, and BleepingComputer later reported OpenAI relaxed usage limits on its GPT-5.6 Sol tier and upgraded GPT-5.5. Until OpenAI commits to a date, the Polymarket curve remains the loudest public signal of when the industry expects the next frontier model.

Why Altman’s Washington trip matters now

Altman is scheduled to meet Treasury Secretary Scott Bessent and Commerce Secretary Howard Lutnick, and to huddle with lawmakers including Sen. Mark Warner, as reported by POLITICO and Semafor. The trip is timed to the administration’s 60-day window to finalize voluntary review rules for advanced models, a process OpenAI, Anthropic and Google jointly weighed in on.

The White House order, signed June 2, asks companies to submit frontier models for safety testing 30 days before release. OpenAI previously amended the rollout of its ChatGPT-5.6 model to government-approved partners only, a move Altman called not the company’s “preferred” path. Altman has framed the staged rollout as a necessary trade-off while a more sustainable government process is built, per POLITICO’s reporting.

Polymarket has been busy beyond AI this month. The platform’s fed rate hike and July no-change odds have drawn heavy trading alongside the GPT-6 contract.
