Grok spent most of 2025 and early 2026 as the fastest-growing AI chatbot in percentage terms. That growth hit its first plateau in March, and the plateau has essentially held through June: Grok’s US mobile app share has stabilised rather than continued climbing, while xAI has kept shipping supporting products (voice, video generation, a coding agent) without landing the headline release everyone’s been waiting for, Grok 5.
The more interesting update is a data point almost nobody was tracking directly: SpaceX’s own IPO filing disclosed Grok’s monthly active user figures, and they’re considerably higher than previously reported ranges.
Grok AI Usage Stats – The Key Numbers, July 2026
- ~117 million monthly active users as of March 2026, per SpaceX’s IPO filing, up from 35 million in December 2025 and ~60 million in January 2026
- Grok’s global web traffic market share sits at ~2.8% (Similarweb, April to May 2026), holding roughly steady rather than continuing to climb
- Grok’s US mobile app DAU share has plateaued since March’s dip to 13.5%, with no clear rebound as of the June Apptopia data brief
- Grok 5 has not shipped as of July 1, 2026. Both the original Q1 2026 and the subsequent Q2 (May to June) target windows have now passed
- xAI shipped Grok Build (agentic coding CLI, May 29), Grok Voice (June 4), and Grok Imagine Video 1.5 (May 30/June 3) instead, plus a 1.5-trillion-parameter coding model, Grok V9-Medium, which finished training in June
- Colossus 2, xAI’s next-generation supercluster, completed its upgrade to 1.5 gigawatts and 550,000+ Nvidia Blackwell GPUs in late April 2026
- SpaceX itself has now IPO’d; some reporting puts its debut valuation above $2 trillion, with xAI (merged into SpaceX in February at a combined $1.25 trillion) now part of that public entity
JUST IN: 117 million monthly active users used Grok’s AI features as of March 31, 2026, out of 550 million total MAUs across Grok and X, per SpaceX’s S-1 filing.

Grok’s User Numbers:
Earlier estimates put Grok’s monthly active users in a wide, uncertain range of 50 to 64 million, reflecting genuine disagreement between third-party estimates (xAI itself doesn’t publish clean MAU figures, and Grok’s usage is entangled with X’s own userbase). That range now looks conservative.
SpaceX’s own IPO filing, a far more authoritative source than any third-party estimate since xAI is now a wholly owned SpaceX subsidiary, disclosed that Grok features hit approximately 117 million monthly active users in March 2026, up from 35 million in December 2025 and an estimated 60 million in January. That’s roughly a 95% increase quarter on quarter and puts Grok’s user base meaningfully ahead of where most independent trackers (DemandSage, SEOProfy, Business of Apps) had placed it.
This creates an interesting discrepancy worth flagging directly: DemandSage’s Semrush-based estimate for the same period was closer to 30 million unique visitors, while xAI’s own internal reporting (as previously cited by Business of Apps) suggested 64 million. The SpaceX filing’s 117 million figure is likely capturing a broader definition, “Grok features” across X, the standalone app, and web, rather than a narrower “chatbot app” measure, which is a useful reminder that Grok’s distribution through X makes clean user counting unusually difficult across the industry.
Grok’s Web Traffic:
Some earlier analyses (based on a single April snapshot from investor Rihard Jarc’s Similarweb-sourced reporting) put Grok’s global web traffic share at roughly 6%, level with Claude. More recent Similarweb-sourced tracking, using more granular monthly breakdowns, tells a different story:
Multiple analyses put Grok’s web traffic share at closer to 2.8% through April and May 2026, essentially flat month on month, and well below Claude’s 8.9% and DeepSeek’s 4.0%. The two readings aren’t necessarily contradictory (different panels, different measurement windows, and Grok’s numbers are among the noisiest in the dataset), but the more recent and more granular data suggests Grok’s web share has not kept pace with Claude’s. Grok.com itself continued setting traffic records into March (326.3 million visits, an all-time high), but that growth has since flattened.
| AI Platform | Global Web Traffic Share (May 2026) |
| ChatGPT | 52.7% |
| Gemini | 27.3% |
| Claude | 8.9% |
| DeepSeek | 4.0% |
| Grok | ~2.8% |
| Copilot | 2.0% |
| Perplexity | 1.3% |
Grok’s Mobile App Share:
March’s dip, Grok’s first monthly decline after fourteen straight months of growth, has not reversed as of the most recent Apptopia data:
| AI Platform (US Mobile) | Feb 2026 (peak) | March 2026 | Jun 2026 |
| ChatGPT | ~42% | 38.7% | Continuing to fall |
| Gemini | ~25% | ~25% | ~25% (steady) |
| Grok | 15.3% | 13.5% | Plateaued, no clear rebound |
| Claude | 4.0% | 10.0% | ~17% |
| Copilot | ~10% | ~10% | Down ~60% YTD |
Apptopia’s June 2026 brief doesn’t call out Grok’s share explicitly, but it does note that Claude is now gaining meaningful crossover interest from Grok’s own user base. The overlap between Grok and Claude users rose 171% year to date to 11.1%, while Grok’s overlap with ChatGPT has stayed flat. Read together, this suggests Grok’s growth engine (X integration) hasn’t stalled, but Grok may be losing some of the “second AI app” mindshare it briefly held to Claude specifically.
Grok 5: Still Not Here
As of July 1, 2026, xAI’s next flagship model, Grok 5, still hasn’t shipped.
What has shipped instead:
- Grok Build 0.1 (May 29, 2026): an agentic coding CLI with a 256,000-token context window, priced at $1/$2 per million input/output tokens, supporting up to eight parallel sub-agents
- Grok Voice (June 4, 2026): conversational spoken interaction, initially mobile-only
- Grok Imagine Video 1.5 Preview (May 30, API access from June 3): image-to-video generation with native audio, currently ranked #1 on the Image-to-Video Arena leaderboard
- Grok V9-Medium: a 1.5-trillion-parameter coding model (three times the size of its predecessor), trained on Cursor data, which finished training in June with a public release expected mid-June
None of these is Grok 5. The leading candidate for the actual Grok 5 release remains a rumoured 6-trillion-parameter mixture-of-experts model training on Colossus 2, potentially expanding Grok’s multi-agent system from 4 to 16+ agents. Prediction markets gave it roughly a one-in-three chance of shipping by June 30, 2026, a deadline that has now passed without a release, pushing realistic expectations for full API access into Q3 2026.
Have you noticed? Grok has now introduced weekly limits, even for SuperGrok users..

xAI’s Corporate and Infrastructure Story
- Colossus 2 completed its upgrade to 1.5 gigawatts and 550,000+ Nvidia Blackwell GPUs in late April 2026, with plans to expand toward 1 million GPUs and 2GW of capacity
- SpaceX, which acquired xAI in a $1.25 trillion combined-entity merger in February 2026, has since completed its own IPO. Some reporting places its debut valuation above $2 trillion, making it, and by extension xAI/Grok, part of one of the largest public companies in the world
- The Anthropic-Colossus 1 compute-sharing deal remains in effect: xAI continues selling spare Colossus 1 capacity to Anthropic, its most direct model rival, underscoring how compute scarcity is reshaping competitive relationships across the frontier AI industry
The Deepfake Scandal: Where Things Stand
No update has surfaced recently suggesting the underlying regulatory situation has meaningfully changed: investigations remain active in the UK, EU, France, Canada, India, Brazil, and Australia, and the lawsuits filed on behalf of affected minors remain unresolved. Apple’s approval of Grok’s updated app (following the January threat to remove it from the App Store) still appears to hold as of this update, though ongoing reporting suggests moderation gaps persist.
Summing Up Grok AI Usage Stats: July 2026
The picture that emerges is one of consolidation rather than continued explosive growth. Grok’s actual user base, per SpaceX’s own disclosures, is meaningfully larger than most third-party trackers had estimated (117 million versus the 50 to 64 million range previously reported), but its growth rate on both web traffic share and mobile app share has clearly slowed, and its marquee next-generation model, Grok 5, remains unreleased months after it was first expected. Meanwhile, xAI’s corporate story has only gotten bigger: folded into a newly public SpaceX valued north of $2 trillion, with a supercomputer buildout (Colossus 2) that now rivals anything in the industry.
The next real catalyst for Grok’s numbers is almost certainly the eventual Grok 5 launch. Until that ships, expect the current plateau to persist.
