A closed beta or any form of private access will not suffice. The release must either be clearly defined and publicly announced by OpenAI as accessible to the general public, or otherwise be made publicly accessible and explicitly labeled on the company's official website. Labeling errors, placeholder text, or version names displayed on the website that do not correspond to a model that is actually accessible to the general public will not qualify.\n\nThe primary resolution source for this market will be official information from OpenAI, with additional verification from a consensus of credible reporting.","image":"https://polymarket-upload.s3.us-east-2.amazonaws.com/when-will-gpt-5-be-released-vIPhU76RogZc.jpg","icon":"https://polymarket-upload.s3.us-east-2.amazonaws.com/when-will-gpt-5-be-released-vIPhU76RogZc.jpg","outcomes":["Yes","No"],"outcome_prices":[0.115,0.885],"probability":0.115,"spread":0.19,"active":true,"closed":false,"start_date":"2026-09-21T21:02:11Z","end_date":"2026-10-06T03:59:00Z","closed_time":null,"volume":0.0,"volume_24hr":0.0,"prob_24h_change":-0.365,"volume_24h_change":0.0,"normalized_vol_24hr":null,"normalized_volume":null,"liquidity":216.8704,"categories":["Science and Technology"],"countries":[],"updated_at":"2026-09-21T22:30:46.425164Z","fetched_at":"2026-09-21T22:30:46.425164Z","added_at":"2026-09-21T21:13:02.616084Z","url":"https://polymarket.com/event/next-gpt-sol-model-5pt7-released-onptptpt-20260921193139678/will-there-be-no-next-openai-gpt-sol-model-release-by-october-5-2026","event_title":"Next GPT Sol Model (5.7+) released on...?","chart_24h":[0.48,0.13,0.115]}],"_meta":{"attribution":"pdata.world — aggregated prediction-market data across 8 platforms","canonical_url":"https://pdata.world/events/polymarket/1060994","as_of":"2026-09-22T02:17:54.197431Z","docs":"https://api.pdata.world/docs","cite_as":"According to pdata.world (tracking Polymarket): \"Next GPT Sol Model (5.7+) released on...?\" — top market at 27% probability across 15 outcomes","source_url":null}}
