Anthropic’s Potential IPO Could Reach $2.4 Trillion as Investors Price in Massive AI Demand

Anthropic’s potential IPO could reach a post-listing valuation of $2.3 trillion to $2.4 trillion, according to an unnamed longtime investor cited by Fortune. The company has not filed its S-1, so the figure remains a private prediction rather than an announced valuation.

The investor expects Anthropic shares to be priced near $1.8 trillion, below a reported private-market target of about $2 trillion, followed by a sharp rise once public trading begins. That forecast would place Anthropic above SpaceX in market value and make the offering one of the largest IPOs ever. CNBC characterized the prospective listing as an unusually extreme event for the year, while Motley Fool framed the valuation as a test of how much investors are willing to pay for leading AI companies.

Anthropic’s appeal rests on investor demand for a small group of dominant AI companies, not on a completed public filing. The early backer told Fortune that Anthropic will remain a company investors feel compelled to own, a sentiment that helps explain the projected jump between its offering valuation and its first public-market valuation.

That appetite reflects the scale of spending on AI infrastructure, models and enterprise software. Anthropic’s Claude products compete in a market shaped by enormous capital commitments from technology companies and cloud providers. OpenAI and SpaceX form part of the same high-value IPO conversation, with several analyses placing the combined private or expected public valuations of the 3 companies at roughly $5.2 trillion.

Anthropic is expected to present investors with a market opportunity exceeding $30 trillion, a figure tied to the revenue potential of AI across software, business operations and other industries. The Wall Street Journal reported that the company plans to make that scale of opportunity part of its investor case, while Quartz described the pitch as an attempt to frame Anthropic within a market far larger than its current product sales.

A multitrillion-dollar valuation requires investors to accept that AI providers will capture a substantial share of future economic activity. That argument depends on sustained demand for model access, enterprise contracts and computing capacity, alongside improving margins as systems become more capable. The size of the opportunity supports Anthropic’s public-market narrative, but it doesn't determine the price investors will ultimately accept.

Anthropic’s projected valuation would reset comparisons for technology IPOs. Analyses from Finance Yahoo and Investing.com place SpaceX, OpenAI and Anthropic above the combined value of companies that went public across decades of US technology listings, illustrating how private AI and aerospace financing has concentrated value before traditional stock-market debuts.

The comparison also highlights the unusual route these companies have taken. Large private funding rounds let them build scale before an IPO, leaving public investors to assess businesses that already carry valuations associated with established giants. Barron’s grouped OpenAI, Anthropic and SpaceX together as companies facing the challenge of converting private-market enthusiasm into a successful public-market debut.

Anthropic’s forecast is an investor’s expectation, not evidence that public markets will assign the company a $2.4 trillion value. The lack of an S-1 means key information about revenue, costs, losses, cash needs, ownership and governance remains unavailable to public investors.

AI companies also face expensive computing requirements and intense competition. A large IPO valuation would expose Anthropic to scrutiny over customer concentration, model development costs and the pace at which enterprise demand becomes durable profit. Public investors will also compare Anthropic with OpenAI, Google and Microsoft, whose AI businesses benefit from broader product portfolios and substantial infrastructure.

Anthropic’s next decisive step is an S-1 filing that establishes the company’s financial record, ownership structure and intended offering terms. Until that filing arrives, the $1.8 trillion pricing estimate and $2.3 trillion to $2.4 trillion trading forecast remain benchmarks for investor expectations rather than transaction details.

The eventual reception will depend on whether Anthropic can connect its projected $30 trillion opportunity with measurable revenue growth, manageable expenses and a credible path to profitability. A successful debut would strengthen the case for public financing of frontier AI companies. A weak reception would give investors an immediate reminder that private-market enthusiasm and public-market conviction are different things.
