Grok 4.6 released by 2026?

Platform comparison

Market context

SpaceX's xAI division must release a Grok model explicitly numbered 4.6 or recognised as its direct successor to the general public by mid-August 2026 for this market to settle affirmatively. The 0% crowd probability reflects scepticism that such a release will occur within the specified timeframe, despite xAI's track record of iterative updates to its flagship chatbot.

xAI released Grok 3 in early 2024, followed by Grok 4 later that year, and Grok 4.5 in late 2024. This cadence suggests roughly six-month intervals between major and point releases. However, the progression from 4.5 to 4.6 represents a minor version bump rather than a flagship leap, which historically carries lower urgency for public deployment. Comparable trajectories in the broader LLM market—such as OpenAI's GPT-4 to GPT-4 Turbo progression—show that point releases often remain restricted to API partners or premium tiers for extended periods. The zero probability priced across major books (Polymarket, Kalshi, Betfair, Smarkets) suggests traders view a public 4.6 release by August 2026 as substantially less likely than a 4.7 or 5.0 announcement instead.

Traders should monitor xAI's quarterly announcements and Elon Musk's public statements regarding product roadmaps. Kalshi's tighter KYC requirements and Betfair's decimal-odds format may appeal differently to those hedging against surprise acceleration in xAI's release schedule. Any formal commitment to a 4.6 timeline, or evidence of beta testing among external users, would constitute a material catalyst for repricing across all platforms.
