Key Highlights
- Brad Gerstner from Altimeter Capital predicts Anthropic could achieve $80B–$100B ARR by late 2026
- Current ARR has surpassed $30B, a massive jump from $9B recorded at 2025’s close
- Claude’s daily active user count more than doubled between February and March 2026
- The company now serves over 1,000 enterprise clients spending $1M+ annually
- March data shows ChatGPT losing ground while Claude and Gemini capture increasing market share
The artificial intelligence company Anthropic is experiencing what Brad Gerstner describes as one of technology’s most rapid revenue expansions ever witnessed. The Altimeter Capital founder shared during a weekend podcast that the firm’s annual recurring revenue could surge to somewhere between $80 billion and $100 billion before 2026 concludes.
This projection represents approximately a threefold increase from current levels. Anthropic’s ARR has already crossed the $30 billion threshold, marking a significant leap from the roughly $9 billion reported when 2025 ended. Just months ago in early 2026, that number stood at approximately $15 billion.
The company had initially set its sights on reaching between $20 billion and $26 billion in ARR for the entire year. Those targets have been decisively exceeded.
According to Gerstner, Anthropic has experienced a dramatic “rebound” during the last three months following a period where it received less attention throughout 2025. He now believes the company is moving faster than OpenAI, which currently reports ARR estimated at $24 billion to $25 billion.
Business Customers Driving Massive Expansion
Anthropic now counts more than 1,000 corporate clients who each spend in excess of $1 million annually on its services. The company’s Claude AI models have found widespread adoption across software development, workflow automation, and API integration applications.
The AI firm introduced Claude CoWork at the start of 2026 and recently rolled out an innovative AI model named Mythos. These product launches have maintained strong industry attention on the company’s offerings.
To accommodate this explosive expansion, Anthropic has partnered with Google and Broadcom on building out 3.5 gigawatts of computational infrastructure. Gerstner emphasized that reaching the $100 billion ARR milestone will demand substantial infrastructure investments.
Market Share Shifts Favor Claude
Recent analytics from BNP Paribas reveal that Claude’s portion of chatbot website traffic nearly doubled, climbing from 3.6% in February to 6.6% by March’s end. The platform’s average daily active users increased from 0.8% to 1.8% during the identical timeframe.
Google’s Gemini chatbot also posted gains, with its website visit percentage advancing from 26.2% to 28% in March.
While ChatGPT continues holding the leading position among AI chatbots, it experienced declines in both web traffic and mobile application usage during March, based on analysis from BNP researchers headed by Nick Jones.
Amazon received mention in the BNP analysis as well. Uber recently broadened its deployment of Amazon’s Gravitron4 and Trainium3 chip technology. Amazon’s CEO Andy Jassy revealed that AWS AI-related ARR has reached $15 billion, while chip-focused ARR stands at $20 billion.
Meta’s newly launched Muse Spark AI model triggered a significant spike in downloads for the Meta AI application. BNP researchers indicated this release demonstrates Meta’s advancing capabilities in artificial intelligence development.
Anthropic ranks among multiple private technology firms potentially planning initial public offerings in 2026, with market observers estimating its valuation near $300 billion.
