VangAI analysis
VangAI edge: -78 pp
- xAI has not announced an official release date for Grok 5.
- Previously stated release timelines have been missed.
- The latest released model is Grok 4.7, released on September 21, 2026.
- xAI plans to release Grok 4.8 and 4.9 before Grok 5.
It's like a scheduled movie release that keeps getting postponed without a new premiere date.
Market rules
The market resolves to YES if xAI officially releases the Grok 5 model to the public (public release through the Grok app/website or API) by October 31, 2026, inclusive. The market resolves to NO if Grok 5 is not released to the public by this date. The release of interim models (Grok 4.5, Grok Imagine, etc.) or closed demos for a limited audience does NOT count as a basis for YES. As of August 19, 2026, Grok 5 remains in development, and the official release date is unconfirmed; previously stated deadlines (Q1 2026, Q2 2026) have been missed. Resolution is based on the official announcement by xAI on x.ai and/or the @xai account on X.
