What happens next, by when, and how sure we are

Probability is how likely an outcome is by its deadline. Confidence, shown as bars, is how strong the evidence behind that number is. Estimates move only when verified evidence does, and every question is scored when it resolves.

Will xAI make Grok 5 generally available to the public by 2026-12-31?

Laurenceo estimate: 22% (Unlikely) by December 31, 2026. Last updated November 2, 2026.

How it resolves

Resolves YES if, on or before 2026-12-31, xAI makes a model officially named Grok 5 available to the public, through the Grok app, X or the xAI API (a paid tier counts; a closed preview for selected testers does not). Resolves NO otherwise.

Reasoning

Grok 5 has missed targets from late 2025 through the second quarter of 2026. The current flagship is Grok 4.7, released 21 September 2026, and Musk's September comments put Grok 4.8 and 4.9 ahead of Grok 5 with no date.

Evidence

  • Against. Grok 5 had not been released as of 11 October 2026 and was absent from the xAI API model list; earlier launch targets in late 2025 and the first half of 2026 all passed. zbuild
  • Against. Musk's September 2026 comments put Grok 4.8 and Grok 4.9 ahead of Grok 5, with no Grok 5 date. Izzedo
