Anthropic Weighs $50B Funding at $900B Valuation to Surpass OpenAI

Anthropic, the maker of the Claude AI assistant, is considering a massive new funding round that could raise up to $50 billion at a staggering valuation exceeding $900 billion, potentially making it the world's most valuable AI startup ahead of rival OpenAI. According to sources familiar with the matter cited by TechCrunch and Bloomberg, the company has received multiple preemptive offers in the $850 billion to $900 billion range, marking a sharp jump from its $380 billion valuation in a February 2026 round where it secured $30 billion from investors.

This prospective deal reflects the feverish investor interest in Anthropic amid the ongoing AI boom, with the company now weighing bids after initially resisting proposals around $800 billion earlier this month. As reported by TechCrunch, Anthropic faces pressure to lock in this capital, which could represent its final private fundraising before a potential initial public offering. A board meeting in May is expected to finalize decisions on the round's size—projected at $40 billion to $50 billion—and terms, though no formal offers have been accepted yet.

Major backers like Amazon and Google have already poured billions into Anthropic, providing indirect public market exposure through their shares. Bloomberg notes Amazon's aggressive stance, having invested $5 billion at a $350 billion valuation with plans for up to $20 billion more, while Google committed $10 billion at the same level, eyeing another $30 billion tied to performance milestones. It's unclear if these tech giants will participate in the new round, but their involvement underscores Anthropic's strategic importance in the race for advanced AI dominance.

The valuation surge positions Anthropic to surpass OpenAI, last valued near $852 billion in late March 2026, highlighting the breakneck pace of AI funding. Just months after its prior raise, this move signals sustained hype around generative AI tools like Claude, even as discussions remain early-stage. For investors and the broader market, the outcome could ripple through stocks like Amazon, Google, Microsoft, and Nvidia, amplifying AI's influence on global tech valuations.

Meanwhile, the AI funding frenzy extends beyond Anthropic. TechCrunch reported Parallel Web Systems, an AI agent startup led by former Twitter CEO Parag Agrawal, hitting a $2 billion valuation with a $100 million raise from Sequoia—its second such round in five months. Bloomberg detailed Flourish, a brain-inspired AI venture by Meta's former Neural Band leader Thomas Reardon, targeting $2.5 billion for energy-efficient systems. These developments illustrate how startups are capitalizing on AI's momentum.

What happens next remains pivotal: a successful close could fuel Anthropic's expansion in AI safety and capabilities, affecting competitors, users, and regulators worldwide. Developers, enterprises relying on Claude, and shareholders in backer companies stand to feel the impact, as this round tests the limits of private market enthusiasm before any public debut.
