Brad Gerstner, founder of the investment firm Altimeter Capital, said Anthropic could triple its annual revenue run rate (ARR) in 2026. Speaking on a podcast on Saturday, Gerstner stated he would not be surprised if Anthropic exits the year with an ARR between $80 billion and $100 billion.

Anthropic Outpaces OpenAI Revenue Run Rate
Gerstner, a tech investor known for early bets on companies like Meta Platforms (META) and Uber Technologies (UBER), said Anthropic is gaining ground on OpenAI. The company’s ARR has now surpassed OpenAI’s estimated $24 billion to $25 billion range. That lead comes as Anthropic’s ARR climbed past $30 billion, up from about $9 billion at the end of 2025.
Earlier in 2026, the figure stood at around $15 billion, highlighting its rapid growth over a short period. As a result, Gerstner added that Anthropic has rebounded over the past 90 days after being largely overlooked last year and is outperforming OpenAI. He described the company’s revenue surge as one of the fastest in tech history.
Meanwhile, the company previously targeted an ARR of $20 billion to $26 billion for 2026, indicating current performance is already above expectations. Scaling toward Gerstner’s projected $100 billion run rate would require major computing capacity, which Anthropic is already addressing through partnerships with Google (GOOGL) and Broadcom (AVGO).
Anthropic AI Models Continue Driving Growth
Anthropic’s growth remains driven by enterprise demand, with its Claude AI models widely used in coding, automation workflows, and API-based services. As of April, more than 1,000 business customers are now spending over $1 million annually, highlighting strong adoption and expanding use cases.
The private company has also stayed in focus across the AI sector following a steady rollout of new tools, including Claude CoWork, launched in January 2026, and the Mythos AI model unveiled last week. Gerstner said Anthropic’s revenue surge reflects strong demand for its models, adding that enterprises are rapidly adopting the tools because they improve business performance.
Which Companies Are Going IPO in 2026?
Anthropic is among the private companies targeting a potential initial public offering (IPO) in 2026, with an estimated valuation of about $300 billion. Other possible listings include SpaceX, OpenAI, Databricks, Bytedance, and more. However, only SpaceX and OpenAI have made concrete steps towards a possible listing, with SpaceX reportedly planning a mid-2026 roadshow and OpenAI signaling a potential IPO in the second half of 2026.
