PendingQ1 2026 (ended March 31) closed with no Grok 5 release. The Information reported Nov 14, 2025 that xAI had pushed Grok 5 to the following year, and as of June 2026 it remains unreleased — missing Musk's stated 'Grok 5 is Q1' target. The Information — xAI Delays Grok 5 Release to Next Year (Nov 14 2025) ↗
After missing his August 2025 promise that Grok 5 would ship 'before the end of 2025' (tracker entry #107), Musk moved the goalpost to Q1 2026 on the Moonshots podcast. Q1 2026 ended with Grok 5 still training on the Colossus 2 supercluster; as of June 2026 xAI was pointing to a Q2 window. Related iconic claim: Musk's verified Oct 18, 2025 tweet 'My estimate of the probability of Grok 5 achieving AGI is now at 10% and rising' (https://x.com/elonmusk/status/1979431839824777673).
