80% of Anthropic's Planned $518B Compute Spending Is Non-Cancelable

About 80% of Anthropic's planned $518 billion in cloud and compute spending over the next decade is non-cancelable or payable regardless of how much capacity it actually uses.
That implies roughly $414 billion of commitments could remain payable even if Anthropic ultimately consumes less compute than expected.
The structure highlights the enormous fixed financial obligations frontier AI companies are taking on as they race to secure long-term access to chips, cloud infrastructure and data-center capacity.
