Claude Surpasses Grok and DeepSeek in Web Traffic for the First Time: AI Chatbot Market Enters Multi-Polar Era

According to SimilarWeb data, Anthropic's Claude surpassed both Grok and DeepSeek in daily web visitors for the first time in late February 2026. Claude.ai's daily visits surged to approximately 14 million, while Grok.com and DeepSeek.com remained in the 9-11 million range.

The competitive landscape among the third-to-fifth-place AI chatbots has shifted. While ChatGPT maintains its overwhelming lead, the reshuffling among challengers signals that the market is no longer static.

1. SimilarWeb Traffic Data: Claude 14M vs Grok 11M

The shift in SimilarWeb's daily visitor data for Claude.ai has been dramatic. Through mid-February, Claude.ai averaged 4-7 million daily visitors, while Grok.com and DeepSeek.com each maintained 9-11 million, comfortably ahead of Claude.

The turning point came around February 26. Claude.ai's daily visitors surged to approximately 14 million, overtaking both Grok and DeepSeek simultaneously. This acceleration built on an already impressive growth trajectory: monthly visits reached 176.12 million by December 2025, representing 10.3x growth in just seven months.

It's worth noting that this data reflects web traffic only and doesn't include mobile apps or API usage. While it has limitations as a measure of total user base, it serves as a meaningful indicator of consumer interest.

2. AI Chatbot Market Share: The End of ChatGPT's Dominance

Fortune's report on January 2026 SimilarWeb market share data reveals the bigger picture. ChatGPT's share stands at 64.6%, down 22 percentage points from 86.7% twelve months ago. Google's Gemini holds 22% in second place, followed by xAI's Grok at 3.5%, DeepSeek at 3.3%, and Claude at 2.1%.

Crucially, Claude's 2.1% reflects January data. The late-February surge hasn't been captured yet, and March figures are likely to show a meaningful increase in Claude's share.

ChatGPT's declining share isn't due to product deterioration. The market itself is becoming multi-polar. Gemini's steady growth, DeepSeek's open-source momentum, Grok's X (formerly Twitter) integration strategy, and Claude's performance-first positioning each carve out distinct user bases.

3. Claude's Growth Drivers: From Code to Enterprise

Multiple growth engines underpin Claude's traffic surge. The most prominent is Claude Code's explosive adoption. Anthropic's AI coding tool reached $1 billion in annual recurring revenue just six months after launch, with estimates placing it above $2 billion as of January 2026.

Anthropic's enterprise positioning is equally noteworthy. The company commands 33% of the enterprise AI market, ahead of OpenAI at 25% and Google at 20%. User engagement metrics tell a compelling story as well, with Claude averaging 34.7 minutes per day, the highest among competitors, suggesting deep rather than superficial usage.

The viral effect of hitting No. 1 on the App Store in late February, along with reflected interest from the Pentagon contract controversy, contributed to the short-term traffic spike. But beyond these event-driven effects, Anthropic's revenue trajectory from $1 billion in early 2025 to an estimated $9 billion by year-end reflects structural growth.

In Closing: The Era of Challengers Begins

Claude's first-ever overtaking of Grok and DeepSeek in web traffic is a milestone, not a victory declaration. ChatGPT still commands roughly two-thirds of the market and dominates in app downloads and API usage. But the trend from 86.7% to 64.6% market share over twelve months appears difficult to reverse.

The AI chatbot market is transitioning from a single-winner game to a multi-polar competition where each player leads with distinct strengths: performance (Claude), ecosystem (Gemini), open source (DeepSeek), and social integration (Grok). How far Anthropic, now valued at $350 billion, can climb in this landscape will be answered by the market data of the second half of 2026.
