OpenAI's accelerated monthly model releases, including GPT-5.4's rollout in early March 2026 with superior reasoning over rivals like Claude Opus 4.6, have solidified trader consensus that GPT-6—a next-generation large language model—remains on track for late 2026, pricing an 83% implied probability by December 31, 70% by September 30, and just 18% by June 30. Pre-training completion on the "Spud" model (likely GPT-5.5) as of March 25 signals an imminent April launch, further spacing out the GPT-6 timeline amid competitive pressure from xAI's Grok 5 beta and Anthropic's Claude Mythos. Traders eye Q2 earnings and developer conferences for timeline clues, with historical delays underscoring execution risks.

For this market to resolve to "Yes," GPT-6 must be launched and publicly accessible, including via open beta or open rolling waitlist signups. A closed beta or any form of private access will not suffice. The release must be clearly defined and publicly announced by OpenAI as being accessible to the general public.
GPT-6 refers to a product explicitly named GPT-6 (e.g. ChatGPT-6o would count), or one that is recognized as a successor to GPT-5, similar to the progression from GPT-3 to GPT-4. Products labeled as GPT-5.5 or similar will not count for this market's resolution.
The primary resolution source for this market will be official information from OpenAI, with additional verification from a consensus of credible reporting.
