Anthropic's IPO Is Coming: 5 Key Numbers Investors Need to Know

Anthropic has filed its IPO, potentially making it the largest one ever and outpacing Space Exploration Technologies Corp (SPCX -2.25%). Before investing in the AI company's stock, there are several key numbers investors should consider. Anthropic's revenue has surged to $16.3 billion, marking a year-over-year increase of 1,300%.

However, investors would be paying a hefty premium for the stock, translating to an annual run rate of about $32 billion and a valuation of more than 60 times revenue. While Anthropic's operations are growing rapidly, the company is still not profitable, incurring a $693 million operating loss in the first two quarters of the year, compared to a $2.1 billion loss in the same period last year.

Concentration risk is a concern for investors, as approximately one-fifth of Anthropic's revenue comes from just two customers. Additionally, compute and infrastructure expenses have skyrocketed to $8.9 billion during the first half of the year, up from $7.3 billion in all of 2025. These expenses are expected to rise further, potentially leading to significant cash burn and the need for more stock offerings, which could dilute shareholders.

The high spending on compute may raise concerns among investors, especially with rising interest rates. Similar to SpaceX, Anthropic's IPO may initially garner strong interest but could face a sharp decline afterward. Despite its impressive growth, investors should approach the IPO cautiously, as purchasing the stock at such a premium may not be the best decision.
