About this market
OpenAI’s release of GPT-5.5 (codenamed Spud) in April 2026, which incorporated many of the memory and agentic features previously teased for GPT-6, has shifted trader expectations for the next major numbered model to the second half of the year. No official architecture details, parameter counts, or timelines have been disclosed for GPT-6 itself, while recent model updates have focused on refining GPT-5.5 response quality rather than advancing a successor. Competitive pressure from other labs, ongoing Stargate-scale infrastructure builds, and the company’s pattern of shorter release cycles after GPT-5 support a base case of Q3–Q4 2026, with Polymarket-implied odds showing low near-term probability but rising conviction for a December 2026 launch. Upcoming developer events or earnings commentary could still introduce new signals.
