Nvidia Weighs $10 Billion Anchor Investment in Anthropic IPO

Anthropic, one of the leading developers in generative artificial intelligence, is seeking public-market capital to expand model development and computing infrastructure. Nvidia has previously committed $10 billion to the company, while the two firms are conducting deep technical optimization for Nvidia’s new GPU architecture. The offering is therefore viewed as a major test of investor appetite for AI companies and the sustainability of the sector’s elevated valuations.

Anthropic has postponed the marketing phase of its initial public offering until mid-October, placing the roadshow shortly before the U.S. midterm elections. Investors are watching whether the revised timetable affects demand or pricing. Market expectations indicate that Anthropic could secure a valuation exceeding $2 trillion at its listing, a level that would make the transaction one of the largest technology IPOs on record.

Anthropic, a leading generative artificial intelligence startup, is competing with OpenAI and other developers for enterprise and consumer customers. A large revolving credit facility would give the company additional flexibility to fund operations and expansion. Such arrangements are also commonly finalized before a company formally appoints banks to underwrite an initial public offering, making the proposed increase a significant signal of Anthropic’s capital-markets preparations.

Anthropic plans to expand its revolving credit facility fivefold, to $15 billion from $2.5 billion, Bloomberg reported. The company is stepping up preparations for a potentially massive IPO whose fundraising target could match or surpass the record associated with SpaceX. Anthropic has not disclosed a formal listing date or named underwriting banks, leaving the transaction’s timing and final size subject to further negotiations and market conditions.

Anthropic, the developer of the Claude family of artificial-intelligence models, has emerged as one of OpenAI’s most closely watched rivals. Rapid adoption by corporate customers has strengthened the company’s revenue outlook and investor appetite. A listing at a valuation of as much as $2 trillion could eclipse SpaceX and become the largest initial public offering on record, underscoring Wall Street’s enthusiasm for generative AI.

Anthropic began preparations for an IPO in 2026 and could move ahead as early as the autumn. Second-quarter revenue increased fourteenfold and the company turned profitable, while annualized revenue climbed to $65 billion. The Wall Street Journal also reported that Anthropic’s internal projections put its long-term potential revenue above $30 trillion, an exceptionally bullish estimate helping support investor expectations for a record valuation.

Anthropic, developer of the prominent Claude AI model, has seen its secondary-market valuation surge 550% this year to $1.2 trillion, overtaking OpenAI and drawing intense market attention. With demand for its shares far outstripping supply, the frenzy has reportedly prompted some investors to sell their homes to buy stock and fueled gray-market trading, forcing the company to issue a warning. The activity underscores the powerful pull that leading AI unicorns exert on capital amid the global artificial intelligence boom.

Bloomberg reported that Anthropic could go public as early as October this year. Three major investment banks are actively arranging meetings between investors and the company's senior executives, while an investor meeting is reportedly set to take place soon. The developments suggest that the company's listing plan, with a valuation closing in on $1 trillion, has entered its final stages. The market is closely watching whether Anthropic can complete the listing in October.

Anthropic was founded by former OpenAI researchers in 2021 and is best known for Claude. Continued funding and cloud-computing support from Google and Amazon underscore the chips, data centers and vast amounts of capital needed to train frontier models. That backing has also made Anthropic a major competitor in the generative AI market.

As of July 2026, reports said Anthropic had completed a $65 billion Series H funding round at a post-money valuation of $965 billion, higher than OpenAI's. Samsung, SK hynix and Micron participated as strategic investors. The new capital will fund model development and computing infrastructure, with Anthropic's valuation closing in on $1 trillion.

Anthropic, the maker of the Claude artificial-intelligence models, has emerged as one of OpenAI’s strongest rivals in the enterprise market. Its “Computer Use” capability, which allows AI agents to operate software interfaces, has sharpened expectations for more autonomous systems. A public listing would test investor appetite for capital-intensive AI developers whose rapid growth is accompanied by heavy spending on computing infrastructure, talent and model training.

Anthropic has reportedly submitted a confidential S-1 filing and is discussing an initial public offering with Wall Street banks as soon as October 2026. Morgan Stanley and Goldman Sachs have been named in reports as lead underwriters. The company is targeting proceeds of more than $60 billion and a valuation of about $380 billion, though newer reports have cited substantially higher figures. The timing, valuation and offering size remain subject to market conditions and could change.

Nvidia is a major supplier of the computing chips OpenAI and Anthropic need to develop generative AI, and its equity investments have deepened its partnerships with both model developers. As the funding required for AI training rises, the investments are shaping the relationships among the three companies and reflecting the chip leader’s positioning ahead of potential listings by major AI companies.

Nvidia CEO Jensen Huang recently confirmed that the company had completed a $30 billion investment in OpenAI and a $10 billion investment in Anthropic. OpenAI is expected to go public by the end of 2026. Huang said these could be Nvidia’s final investments in the two companies before their listings, bringing further funding commitments to a close.
