Market rules
Criterion: The market resolves to "Yes" if xAI officially releases the Grok 5 model to the public (API, X/Grok app or web chat) by September 30, 2026, 12:00 UTC inclusive. Threshold: a full public release is required, not a closed beta/waitlist/early access for select users. Source: official release notes page of xAI (docs.x.ai/developers/release-notes) and official xAI/x.ai channels. Edge case: an announcement of the release date without actual public access to the model at the time of resolution counts as "No."
