xAI released Grok 4.7 today, September 21, 2026, driving the near-certain market consensus on an immediate launch. The model features a larger 2.1-trillion-parameter base, extended reinforcement learning on complex tasks, improved self-verification, and a new safeguard stack, delivering gains on coding benchmarks like CursorBench 4.0 and Terminal-Bench while matching Grok 4.6 pricing and speed. It is live now via the xAI API, Cursor, Grok Build, and third-party platforms with no waitlist, following multiple prior timeline adjustments. Traders see negligible odds for any delay because official documentation, API endpoints, and contemporaneous announcements confirm availability, though an unforeseen infrastructure outage remains a theoretical, low-probability disruptor before market resolution.
