ANTHROPIC STORMS PAST OPENAI IN BUSINESS CUSTOMERS AS $900 BILLION VALUATION ROUND CLOSES The scoreboard just flipped. Anthropic now has more paying corporate customers than OpenAI for the first time in its history, with 34.4 percent of verified U.S. businesses reporting they pay for Anthropic services compared to OpenAI’s 32.3 percent, according to the latest Ramp AI Index. A year ago that number was 9 percent. Dario Amodei’s team has done something that was supposed to be impossible: out-executed the company that invented the modern AI industry. The timing lines up perfectly with Anthropic’s blockbuster fundraise. The company has agreed terms on a $30 billion financing round that pegs its valuation near $900 billion, a figure that would officially make it more valuable than OpenAI’s $854 billion March valuation. Sequoia, Greenoaks, Dragoneer, and Altimeter are each committing over $2 billion. Google has separately pledged up to $40 billion in cash and compute. What is driving this is not hype. Annualized revenue hit $30 billion in April 2026, up from $9 billion at year-end 2025, a climb that the company’s own projections failed to anticipate. Claude Code alone cleared $2.5 billion in run-rate revenue. The enterprise shift is real, the momentum is undeniable, and the AI race has a new leader at the top.
