Will Grok 4.20 be released on January 4, 2026?

This market will resolve according to the date (ET) when xAI's Grok 4.20 model is made available to the general public. This market will resolve to "No release by January 31" if xAI's Grok 4.20 model is not made available to the general public by January 31, 2026, 11:59 PM ET. To qualify, Grok 4.20 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 xAI as being accessible to the general public. Grok 4.20 refers to a product explicitly named Grok 4.20, or one that is recognized as a successor to Grok 4.1, similar to the progression from Grok 4 to Grok 4.1. Products labeled as Grok 4.12 or similar will not count for this market's resolution. The primary resolution source for this market will be official information from xAI, with additional verification from a consensus of credible reporting.
