Anthropic’s revenue growth is extraordinary, but the computing bill behind it is even more extraordinary.

Revenue was $4.7 billion in the first quarter of 2026, then jumped to $11.6 billion in the second quarter, when the company also posted its first quarterly operating profit. Media reports put third-quarter revenue at $16.8 billion.

Judging by its revenue trajectory, Anthropic is commercializing at a remarkable pace. After reading the public version of its S-1 filing, Timothy B. Lee also concluded that its financial performance was stronger than many had expected.

But the other side of that growth is enormous long-term commitments.

To support future expansion, Anthropic has committed hundreds of billions of dollars in computing spending to companies including Amazon, Google, SpaceXAI, and Broadcom. For those investments to ultimately pay off, annual revenue will need to grow to hundreds of billions of dollars.

So the real question isn’t how much it can earn today, but whether future growth can deliver on today’s investments.

Revenue surged in the second quarter, but the third quarter did not see a similar acceleration. Is demand for products like Claude Code gradually approaching saturation, or is this just a brief pause in the growth process?

There isn’t enough information to answer that yet. Fourth-quarter figures will be an important clue.

When an AI company commits hundreds of billions of dollars to computing, slowing growth is no longer just a growth problem—it calls into question whether the entire business model can work.
