Anthropic Files for IPO Near $1 Trillion as AI Cost Concerns Mount

Corporate buyers of artificial intelligence services are confronting higher bills than expected at the same moment one of the sector’s leading developers seeks public investors. Anthropic filed confidential paperwork for a U.S. listing this year after private investors valued the company above $965 billion, placing it ahead of OpenAI’s most recent mark of $852 billion. The filing arrives while companies that pay the largest invoices for models such as Claude report uneven returns and while data-center operators continue to expand capacity.

Nvidia chief executive Jensen Huang told an audience at Computex in Taipei that connectivity chips from Marvell Technology will be essential to the clusters now being built, calling Marvell the next potential trillion-dollar company. Marvell shares rose 22 percent in premarket trading the next morning. Alphabet separately disclosed plans to raise $80 billion for AI-related spending. Microsoft and other cloud providers are preparing customer demonstrations of new AI tools to coincide with the increased infrastructure outlays.

Anthropic’s revenue run rate reached nearly $50 billion in its latest private round, and the company recorded its first profitable quarter, according to the Wall Street Journal. It has also overtaken OpenAI in the number of business customers, per data from Ramp. OpenAI chief executive Sam Altman told CNBC that questions about AI costs represent the most substantive criticism the industry faces so far. A Bain survey of nearly 1,000 companies found that 40 percent realized cost savings below 10 percent after AI investments.

The listing will require Anthropic to publish detailed financials, including margins and customer concentration, that investors have not previously seen. Analysts at PitchBook and Hargreaves Lansdown noted that the prospectus will serve as an early benchmark for how public markets price generative-AI businesses. SpaceX is expected to test a comparable valuation in the same window, creating the largest simultaneous pre-IPO capital event on record.

Separate from revenue questions, local opposition to data-center construction has produced the first statewide moratorium attempt in Maine and a voter referendum blocking a project in Port Washington, Wisconsin. The environmental and power demands of the facilities remain subjects of ongoing utility-rate and water-use disputes in multiple states.
