Grok 4.4 released by 2026?

Platform comparison

Market context

xAI has confirmed that Grok 4.4, a 1-trillion-parameter model, will arrive within roughly two to three weeks from Elon Musk’s latest public schedule, with training data finalised through early April 2026[1]. This follows a clear progression: Grok 4 launched in July 2025 after a two-week tease, and Grok 4.1 rolled out immediately to all users shortly after[6][10]. The current 0% crowd-implied probability for public release by June 2026 appears inconsistent with this timeline, given that Grok 4.5 is already in private beta at SpaceX and Tesla as of late June 2026, and Grok 4.4 is expected to follow within weeks[3]. Historical launch patterns suggest xAI moves swiftly from announcement to deployment, often within 10–14 days, making a mid-2026 public release for Grok 4.4 highly plausible[6].

Traders should monitor xAI’s official changelog and Musk’s X posts for the exact Grok 4.4 launch window, which is pegged to roughly two to three weeks from his last update[1]. Key dependencies include the completion of supervised fine-tuning and alignment work, which typically takes 4–6 weeks post-pre-training, but xAI has compressed this cycle in recent releases[4]. The rollout of Grok Voice and Grok Imagine 1.5 Preview in early June 2026 signals that infrastructure is ready for broader deployment, and Grok 4.4’s public release is expected to follow the same rapid cadence as Grok 4 Fast, which launched live on grok.com and in mobile apps within days of announcement[2][5]. No confirmed date exists yet, but the infrastructure and team momentum strongly support a public release before the settlement deadline.

Can I import form data and lineups?

This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
