Anthropic IPO: $26B Backing from AI Giants, But Is It a Buy?

Anthropic, a leading artificial intelligence company, is set to go public next week in what could be one of the largest IPOs in history. The company is reportedly targeting a market capitalization of around $1.4 trillion, down from earlier estimates of $2 trillion. Ahead of the IPO, Anthropic released an updated prospectus revealing a massive $26 billion private placement from seven AI giants: Alphabet, Nvidia, Advanced Micro Devices, Broadcom, Micron, Microsoft, and Taiwan Semiconductor Manufacturing Company. These companies have committed to purchase Anthropic shares at the IPO price.

The investment is a major vote of confidence from some of the most influential players in the AI industry. Anthropic's revenue has been growing rapidly, reaching $33.2 billion in the nine months ended September 30, up 1,206% year over year. However, the company remains unprofitable, with an operating loss of $1.3 billion (improved from $5.2 billion a year earlier) and a net loss of $104 billion, largely due to non-cash charges related to convertible notes and other financial instruments.

The $26 billion cash infusion will help fund Anthropic's massive AI build-out, which requires significant capital. Beyond the immediate financial boost, the investment creates a symbiotic relationship: as Anthropic grows, it will demand more infrastructure from these backers, such as Nvidia's hardware and Google Cloud services. This could create a virtuous cycle benefiting both Anthropic and its investors.

Anthropic's annualized revenue run rate was $81 billion as of October. At a $1.4 trillion valuation, the stock would trade at about 17.3 times annualized revenue. If the valuation lands at $1 trillion, that multiple drops to 12.3 times, which may be more reasonable given the company's hyper-growth. However, the recent SpaceX IPO serves as a cautionary tale: despite strong financial results, SpaceX stock has not gained much because expectations were already baked into the price. Anthropic could face a similar fate.

The Anthropic IPO is significant because it represents the next major test of the AI investment boom. The $26 billion commitment from AI giants underscores their confidence in Anthropic's technology and its potential to generate substantial returns. For investors, this is a chance to own a piece of a company that is at the forefront of generative AI, a sector that is transforming industries.

However, the valuation is steep. Even at a $1 trillion valuation, Anthropic would trade at 12.3 times annualized revenue—a rich multiple for any company, even one growing as fast as Anthropic. The company's lack of profitability adds to the risk. While the losses are partly due to non-cash charges, the bottom line is still red, and the capital-intensive nature of AI development means more spending ahead.

The involvement of AI giants like Nvidia and Alphabet is a double-edged sword. On one hand, it provides validation and a financial safety net. On the other hand, it creates potential conflicts of interest and dependencies. For example, Anthropic's use of Google Cloud and Nvidia hardware means these companies have a vested interest in Anthropic's success, but they also have significant influence over its operations.

For the broader market, a successful Anthropic IPO could reignite enthusiasm for AI stocks, particularly those of its backers. Conversely, a disappointing debut could dampen sentiment and raise questions about the sustainability of the AI rally. Investors should watch the IPO closely as a bellwether for the AI sector.
