1 account bought into the 「GPT-5.6 Not Yet Released by June 28, 2026」 narrative.

According to PolyBeats monitoring, on the prediction market Polymarket, a new account has placed a $5200 bet on "Will GPT-5.6 still not be released by June 28, 2026?" with an average buy-in probability of 41.6%. The current probability for "Yes" is 67.3%.

OpenAI's latest ChatGPT update, released on the 18th, mainly involves World Cup information, pronunciation guidance, chat summarization, sharing features, in-app linking controls, and iOS image upload speed improvements, with no mention of GPT-5.6. In OpenAI's model release history, the most recent explicit model-level update remains the GPT-5.5 Instant tweak on May 28th.

Previously, researchers briefly spotted a GPT-5.6 label in the Codex backend mapping, but the related records later disappeared, with the initial discoverers considering it more of an accidental exposure. Model traces in backend routes, test codes, and closed environments can only suggest that OpenAI is testing future models.
