Anthropic's S-1: A Few Numbers More Worth Looking At Than the $80.7 Billion Loss

On October 26, Anthropic officially filed its S-1. The document is more than 400 pages long. X user Bojan Tunguz used Opus 5.5 to generate a video under 5 minutes that lists all the key points.

Several key numbers:

• Revenue: $41 million in 2023, $16.3 billion in the first half of 2026
• Net loss of $80.7 billion in the first half, mostly non-cash
• Founders control 50.1% of voting power
• A trust selects 4 of the 7 directors
• Risks: compute commitments, safety, conflict with the U.S. Department of Defense

Just seeing the words "$80.7 billion loss" can easily be frightening. But the S-1 explains that this loss mainly comes from paper losses on convertible notes. Some commenters pointed out that this portion actually corresponds to the shares Amazon will receive. When the company's stock price rises, a corresponding accounting loss appears. Simply put, it is not cash being burned.

But other replies dug up more less optimistic numbers from the S-1:

• Cumulative losses of $132.9 billion
• Convertible notes/debt liabilities of $108.57 billion
• Minimum cloud service commitments (Take-or-Pay): Amazon and Google combined at $224.5 billion, through 2033/2036
• SpaceX compute contract of $120.5 billion, at $3.1 billion per month starting December 2026

These are hard spending commitments. Revenue growth is indeed astonishing, but costs are also locked in.

Now look at control. Common stock has no voting rights. 50.1% of voting power is in Class F founder shares. Four of the seven board seats are selected by a trust associated with the effective altruism (EA) movement. The company is incorporated as a Delaware public benefit corporation (PBC), and its charter allows the board to be free from legal liability when deciding to cease operations.

Some replies pointed out: public investors put in money but have no voting rights. Others argued that the loss on convertible notes is not a real loss and that the financial data itself is strong.

For people focused on AI safety, this structure has its own logic. For ordinary investors, this is something they need to think through clearly.

A screenshot of a Fundrise investor document shows that Anthropic accounts for more than 20% of its innovation fund. Retail money is already betting on this IPO.

Anthropic's S-1 is just the beginning. What is worth watching next is how the market digests these 400 pages.
