Less than three years ago, Anthropic was a scrappy AI safety lab running on idealism and a fraction of OpenAI’s budget. By June 2026, it may be worth more than its former parent.
The San Francisco-based company, founded in 2021 by former OpenAI research executives Dario and Daniela Amodei, closed a $30 billion funding round in February 2026 that valued it at $380 billion. Now, according to Bloomberg, investor demand has pushed proposed valuations past $800 billion, with reports pointing toward a potential $50 billion raise at roughly $900 billion. If that deal closes, Anthropic would overtake OpenAI as the most valuable private AI company on the planet.
The February round is confirmed
The $30 billion raise and $380 billion valuation are well-documented. Bloomberg and the Associated Press both reported the figures with direct attribution to company and investor sources. Federal securities records back them up: Form D filings on the SEC’s EDGAR system for entities labeled “Anthropic II Feb 2026” and “Anthropic PBC Jan 2026” confirm that securities transactions tied to the financing were formally reported to regulators.
The round, described as Series G funding, made Anthropic one of the most richly valued private companies in any industry. It also reflected a sharp acceleration: the company had raised roughly $15 billion across earlier rounds backed by Google, Amazon (which has committed upward of $8 billion), Salesforce Ventures, and other institutional investors.
The $900 billion figure is not yet a done deal
The leap from $380 billion to $900 billion is where the evidence thins. No SEC filing, official Anthropic statement, or named investor commitment confirms the higher number. Bloomberg’s reporting references investor offers at the $800 billion-plus level, but an offer is not a signed term sheet. There is a meaningful gap between investors expressing appetite at a given price and a company actually closing a round there.
Several pieces are still missing. No lead investors have gone on the record. Anthropic executives have not been quoted discussing the higher targets. And the institutional breakdown of who would participate in what would be the largest private funding round in history has not been disclosed by any primary source.
The math alone underscores how unusual the trajectory is. A jump from $380 billion to $900 billion in roughly two months would represent a 137 percent increase in implied value. Even by the standards of AI startups, which have seen wild valuation swings since 2023, that pace is extraordinary. Whether early-stage investor enthusiasm translates into a signed deal at those terms remains an open question.
Why investors are bidding this high
Two forces help explain the frenzy. The first is product momentum. Anthropic’s Claude model family has rapidly gained ground in enterprise settings, and the company’s annualized revenue has grown sharply over the past year as businesses adopt its AI assistants for coding, research, and customer-facing workflows.
The second is a high-profile vote of confidence from Wall Street itself. In early February 2026, Goldman Sachs announced a partnership with Anthropic to deploy AI agents that automate banking tasks. A Goldman deployment is not a startup pilot program. It signals that a major regulated institution trusts Anthropic’s technology enough to put it into production workflows, the kind of enterprise adoption that generates recurring revenue and gives later-stage investors a reason to pay a premium.
The OpenAI comparison
The headline claim hinges on where OpenAI’s valuation stands. OpenAI closed a funding round in late 2025 that valued it at roughly $300 billion, a figure reported at the time by Bloomberg and the Wall Street Journal with attribution to people familiar with the transaction. The company has since been navigating a complex corporate restructuring, shifting from its original nonprofit governance to a for-profit model, a process that has drawn scrutiny from regulators and former board members alike.
If Anthropic closes at $900 billion, it would not just edge past OpenAI. It would nearly triple the gap. That reversal would be remarkable given that Anthropic was founded by people who left OpenAI over disagreements about safety practices and commercialization speed. Dario Amodei, Anthropic’s CEO, has consistently argued that building powerful AI responsibly and building a commercially successful company are not mutually exclusive goals. A $900 billion valuation would be the market’s most emphatic endorsement of that thesis yet.
What to watch before the next round closes
For anyone tracking the AI funding race, the key question is timing and documentation. Anthropic’s February round is a matter of public record. The next round, at whatever valuation it ultimately closes, will produce its own SEC filings and formal disclosures. Until those documents appear, the $50 billion and $900 billion figures should be understood as reported investor appetite, not confirmed corporate milestones.
The gap between the two is where billions of dollars in implied value either materialize or evaporate. And in an industry where sentiment can shift with a single model release or regulatory ruling, nothing is final until the signatures are dry.
