Anthropic Passes OpenAI in Valuation with $65 Billion Round

Anthropic has surpassed OpenAI's valuation after closing a funding round that BigGo Finance reports at $65 billion, a figure that reorders the top of the artificial intelligence industry in a single transaction.

The report, published by BigGo Finance under the headline "The AI Divorce: How Anthropic Surpassed OpenAI's Valuation with a $65 Billion Funding Round That Rewrote the Competitive Landscape," frames the deal as a turning point in the rivalry between the two leading US AI developers. The outlet casts the split between the companies — once close partners in building frontier AI — as a divorce whose financial consequences are now measurable in valuation terms.

What does the $65 billion round change?

The headline number itself carries the story. A round of that size puts Anthropic above OpenAI in market standing, according to BigGo Finance's account. That inversion matters for three reasons the report points to:

• Investor preference shifts. Capital that once defaulted to OpenAI is now flowing to its chief competitor at a scale large enough to flip the ranking. -- Competitive parity is gone. The two companies are no longer fighting from symmetric positions; one now holds the valuation lead.
• The market is consolidating around a two-horse race with a new leader. BigGo Finance describes the round as having "rewrote the competitive landscape" — its central claim.

Why does BigGo Finance call it a "divorce"?

The outlet's framing treats the relationship between Anthropic and OpenAI as a partnership that has fully unraveled. Anthropic was founded in 2021 by former OpenAI staff who left over disagreements about direction and safety. BigGo Finance's use of "divorce" extends that origin story to the present: the $65 billion round marks the moment the breakaway company no longer trails the firm its founders quit.

What is still unconfirmed?

The BigGo Finance dispatch is brief. It does not name the investors in the round, disclose a pre- or post-money valuation breakdown, or specify a closing date. It also does not state OpenAI's current valuation for comparison. Readers should treat the $65 billion figure as BigGo Finance's reporting rather than a confirmed term sheet.

What is clear from the report is the direction of travel: the gap in standing between the two companies has closed, and by BigGo Finance's account it has closed decisively. If the figure holds up as details emerge, the next question for the sector is whether OpenAI's own fundraising plans respond — and whether enterprise customers begin reweighting their AI supplier bets accordingly.
