The release timeline for Elon Musk's Grok 4.20 is uncertain, with on-chain data indicating only a 23% probability of launch before December 31. Initially, Musk projected a 3–4 week timeline, later adjusting to three weeks. Market forecasts now suggest a 75% likelihood of release by January 15, 83% by January 31, and 96% by April 20. The potential delay could impact altcoin markets, as investor sentiment remains closely tied to updates on Musk's projects.
