Anthropic Surpasses OpenAI in Latest AI Funding Valuation

Anthropic has overtaken OpenAI to become the most valuable private artificial intelligence company, reaching a valuation of $965 billion in its latest Series H funding round [2]. The company secured $65 billion in new capital, surpassing the $852 billion valuation OpenAI achieved in March [2].

Key takeaways

• Anthropic’s $965 billion valuation makes it the most valuable private AI startup, moving ahead of OpenAI’s $852 billion valuation [2].
• Anthropic reported a $47 billion annualized revenue run rate, a significant increase from the $10 billion it recorded last year [2].
• While OpenAI is preparing for an IPO with a valuation target above $1 trillion, Anthropic has disclosed a profitable second quarter for 2026, projecting $559 million in operating profit [1].
• Approximately 85% of Anthropic’s revenue is derived from enterprise and developer customers, contrasting with OpenAI’s business model, which remains heavily tied to consumer subscriptions [1].

Diverging Paths to Profitability

The shift in valuation reflects a broader debate regarding the economics of artificial intelligence, specifically whether profitability is best achieved through consumer scale or enterprise revenue [1]. Anthropic’s financial structure is increasingly oriented toward business clients, with over 500 companies spending more than $1 million annually on its Claude platform [1]. This enterprise-heavy model has allowed Anthropic to project $10.9 billion in revenue for the second quarter of 2026, more than double its first-quarter performance [1].

In contrast, OpenAI’s revenue model remains largely dependent on ChatGPT consumer subscriptions, with roughly 95% of its users currently on free tiers [1]. As OpenAI prepares for a confidential IPO, it faces scrutiny over its high operational costs, with projected computing expenditures reaching $121 billion in 2028 [1]. While OpenAI aims for a public market valuation exceeding $1 trillion, it does not expect to reach positive cash flow until 2029 or 2030 [1]. Anthropic, meanwhile, has demonstrated the ability to generate operating profit at scale, though it notes that these figures exclude stock-based compensation [1].

Regulatory Hurdles and Market Momentum

Despite its financial growth, Anthropic has navigated significant regulatory challenges this year. In March, the Pentagon designated the company a "supply-chain risk," prohibiting contractors from using its AI models in work related to the War Department [2]. Anthropic has initiated a lawsuit to challenge this classification, a matter that remains pending in court [2].

The broader AI sector is bracing for a wave of public listings. In addition to OpenAI and Anthropic, Elon Musk’s AI venture housed within SpaceX is expected to pursue an IPO, with reports suggesting a target valuation of $1.5 trillion [2]. As these companies move toward public markets, investors are increasingly focused on the sustainability of AI business models, moving away from the "build-first" approach that characterized the industry's previous three years [1].
