Grok Hits 100M Monthly Active Users — xAI
Published · Updated · By Investus editorial desk (SUNRYU Partners)
xAI's Grok AI assistant has reached 100 million monthly active users, per Kalshi. Compared to ChatGPT (600M+) and Gemini (500M+) it is still in earlier stages, but growth velocity has been notable. X (Twitter) platform bundling and API access are the key user acquisition channels.
What happened
Kalshi reported that Grok, xAI's AI assistant, is approaching 100 million monthly active users. Grok is bundled into X Premium subscriptions and also operates a standalone API.
100M MAU is a meaningful milestone in the AI assistant market — ChatGPT is at 600M+, Gemini at 500M+. Grok has now entered the same conversation.
More detail
Grok's growth path differs from competitors. It benefits from X's 120M+ premium subscribers and 150M+ daily active users as a built-in distribution channel — the platform flywheel that ChatGPT and Gemini lack. Grok also has direct access to X's real-time data stream, giving it a time-sensitive information advantage over competitors with static training cutoffs.
With Elon Musk keeping open the possibility of an X/xAI merger, Grok's MAU trajectory is a key data point in any xAI valuation exercise.
Analyst and house views
xAI is private, with valuation estimates in the $80B–$120B range. 100M MAU provides a foundation for advertising monetization on X and API revenue scaling. Tesla ($TSLA) continues to function as an indirect play on xAI given Musk's controlling stake across both.
