Grok AI Stats October 2026 – Market Share, User Numbers, and More.

Grok’s story in 2026 has been less about the chatbot and more about the company behind it. xAI no longer exists as a separate business: it’s now SpaceXAI, the AI division of a publicly listed SpaceX, and its numbers now show up in quarterly SEC filings rather than leaks and estimates.

Those filings reveal a business growing fast on revenue – mostly from selling compute rather than Grok subscriptions – while Grok’s consumer market share has drifted rather than climbed. On the product side, SpaceXAI has shipped three new Grok models since July, bought Cursor for $60 billion and launched an agent, Grok Bot, that’s growing quickly in enterprise.

Here are the latest Grok AI stats available as of October 2026.

Grok AI Stats – The Key Numbers, October 2026

• 117 million people used Grok’s AI features monthly as of March 31, 2026, up from 89 million at the end of 2025 (SpaceX SEC filings)
• SpaceX’s AI segment generated $2.56 billion in revenue in Q2 2026, up 247% year on year
• The AI segment hit positive adjusted EBITDA of $1.15 billion in Q2 2026 – but still posted a $1.26 billion operating loss
• Grok holds 2.4% of global AI web traffic, down from a peak of around 4% earlier in 2026 (Similarweb)
• Grok Bot, SpaceXAI’s agent product, reached 418,000 users within about a month of launch
• SpaceXAI released Grok 4.5 (July), Grok 4.6 (August 12) and Grok 4.7 (September 21) – with Grok 5 planned before the end of 2026
• SpaceX agreed to buy Cursor for $60 billion, closing the deal in August 2026
• Compute capacity reached 1.4 GW at the end of Q2 2026, up from 0.4 GW a year earlier

Grok User Stats

117 million monthly active users of Grok features (March 31, 2026). SpaceX’s S-1/A filing reports 117 million MAUs using Grok’s AI features, up from 89 million at December 31, 2025.

Takeaway: Grok added 28 million monthly users in a single quarter – a 31% jump.

Around 21% of X’s 550 million monthly users use Grok. The same filing says Grok and X together had 1.3 billion accounts active in the 12 months to March 2026.

Takeaway: almost four in five X users still haven’t touched Grok – that’s SpaceXAI’s biggest built-in growth opportunity.

1.9 million paying SuperGrok subscribers, alongside 4.4 million X Premium subscribers, per the SpaceX filing as reported by Social Media Today.

Takeaway: under 2% of Grok’s users pay for it – consumer monetisation is still Grok’s weak spot.

Grok Bot reached 418,000 users by September 14, 2026, around a month after its August 11 beta launch, growing 24% week on week, per Bloomberg reporting via Yahoo Finance.

Takeaway: Grok’s newest growth engine is enterprise agents, not the chatbot.

Grok Market Share Stats

2.4% of global AI web traffic. Similarweb’s latest update (September 7, 2026) puts Grok in fifth place, behind DeepSeek’s 3.4%. Grok was at 3.7% six months earlier.

Takeaway: Grok’s web share has slipped back below where it was a year ago (2.6%).

AI Platform	6 Months Earlier	Latest (Aug 2026 update)
ChatGPT	56.7%	55.5%
Gemini	25.4%	25.6%
Claude	6.0%	9.3%
DeepSeek	3.4%	3.4%
Grok	3.7%	2.4%
Copilot	1.9%	1.6%
Perplexity	1.6%	0.9%

Takeaway: Claude has pulled well clear of Grok – the two were neck and neck at the start of 2026.

Grok sits in the “under 5%” group of AI assistant apps globally (Sensor Tower, May 2026), alongside Perplexity, DeepSeek and Meta AI.

Takeaway: outside of X, Grok hasn’t broken into the top tier of standalone AI apps.

grok.com traffic peaked at 326.3 million visits in March 2026, then fell to 244.8 million by May (Similarweb via DemandSage).

Takeaway: Grok’s web traffic is volatile and tends to spike around model releases.

SpaceXAI Revenue & Financial Stats

SpaceX’s Q2 2026 earnings release is the most detailed look we’ve ever had at Grok’s business.

$2.56 billion in AI revenue (Q2 2026), up 213% on Q1 and 247% year on year.

Takeaway: SpaceXAI’s revenue has more than tripled in one quarter.

$2.19 billion of that came from AI solutions and infrastructure, driven by $14.1 billion of new cloud compute contracts. Advertising (mainly X) brought in $367 million.

Takeaway: most of SpaceXAI’s money comes from renting out compute, not from Grok users.

AI adjusted EBITDA of +$1.15 billion, versus -$609 million in Q1 – though the segment still made an operating loss of $1.26 billion.

Takeaway: Grok’s parent business is closing in on profitability faster than OpenAI or Anthropic.

$15.8 billion of AI capex in a single quarter.

Takeaway: SpaceXAI is spending on compute at a pace few companies on earth can match.

1.4 GW of compute capacity at the end of Q2 2026, up from 1.0 GW in Q1 and 0.4 GW a year earlier, as Colossus 2 continues to scale.

Takeaway: SpaceXAI has more than tripled its compute in a year – the foundation for Grok 5.

SpaceX’s IPO raised ~$85.7 billion when it listed on Nasdaq (SPCX) on June 12, 2026. The company is now valued at around $2.16 trillion, per INDmoney.

Takeaway: Grok is now part of one of the most valuable public companies in the world.

Grok Product & Model Stats

Three new flagship models in three months: Grok 4.5 (July 2026, built on a 1.5 trillion-parameter foundation model), Grok 4.6 (August 12) and Grok 4.7 (September 21).

Takeaway: SpaceXAI is shipping faster than any other frontier lab right now.

Grok 4.6 API pricing: $2 per million input tokens and $6 per million output tokens, with a 500,000-token context window (per OrcaRouter).

Takeaway: Grok is competing hard on price, particularly for developers.

Cursor acquisition: $60 billion, closed August 14, 2026. Grok 4.6 is integrated across all Cursor plans.

Takeaway: with Cursor, SpaceXAI bought instant reach into one of the biggest developer audiences in AI.

Grok 5 is planned before the end of 2026, after missing earlier Q1 and Q2 targets.

Takeaway: the long-awaited Grok 5 remains the biggest potential catalyst for Grok’s user numbers.

Summing Up Grok AI Stats: October 2026

As of October 2026, Grok is a tale of two businesses. The consumer chatbot has 117 million monthly users but a shrinking slice of AI web traffic and very few paying subscribers. The wider SpaceXAI business, meanwhile, is booming – driven by compute contracts, the Cursor acquisition and a rapid-fire model release schedule.

The next catalyst to watch is Grok 5. Until then, expect Grok’s growth to come from X, Cursor and enterprise agents rather than head-to-head wins against ChatGPT, Gemini or Claude.
