OpenAI's May 5 release of GPT-5.5 Instant—a smarter, more personalized large language model—has solidified trader consensus for GPT-6 arriving later in 2026, with market-implied odds at 95% by December 31 and just 6% by June 30, reflecting the firm's rapid iteration amid unmet April "Spud" launch rumors after March pre-training completion. Sam Altman's April 30 hint of GPT-6 "with extra goblins" fueled brief optimism, but competitive advances like xAI's Grok 4.20, Google's Gemini 3.1 Pro, and Anthropic's Claude 4.6 in early 2026 underscore intense frontier model pressure on benchmarks and agentic capabilities. Watch for OpenAI DevDay or Q3 earnings as potential catalysts shifting timelines.

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.
