Anthropic has signed a $1.8 billion, seven-year cloud infrastructure deal with Akamai Technologies, according to Bloomberg. The agreement is the largest contract in Akamai’s 28-year history and the clearest signal yet that AI labs are buying compute from every available provider as demand for inference capacity outpaces supply.

Akamai disclosed the deal in its Q1 earnings release as a commitment from “a leading frontier model provider” without naming the customer. Bloomberg identified it as Anthropic. Both companies declined to comment officially. Akamai stock closed up 26.58% at $147.71 on Thursday, with late trading pushing the gain as high as 29.62%.

The Numbers

• Contract value: $1.8 billion over seven years
• Average annual revenue: approximately $257 million per year
• Revenue begins: Q4 2026, contributing $20-25 million in the initial period
• Akamai cloud segment current run rate: less than 9% of $4.5B total annual revenue
• The deal would more than double Akamai’s cloud division’s current annual revenue

At 80x year-over-year growth in Claude usage — a figure Anthropic CEO Dario Amodei disclosed at the “Code with Claude” developer conference in San Francisco this week — Anthropic is running out of capacity faster than any single provider can supply it. The Akamai deal is the third major compute commitment in a matter of weeks:

1. Google Cloud: access to up to one million TPU chips
2. SpaceX Colossus 1: 220,000 NVIDIA GPUs across 300+ megawatts of capacity
3. Akamai: $1.8 billion for edge-distributed cloud infrastructure

Why Akamai

Akamai is not a hyperscaler. It built its business on content delivery networks, caching web content close to end-users across thousands of points of presence. That edge topology is now the differentiating asset: running Claude inference closer to users reduces latency in ways AWS us-east-1 cannot.

The deal followed a February 2026 agreement Akamai signed with an unnamed U.S. technology company for a multi-thousand NVIDIA Blackwell GPU cluster, worth $200 million over four years. Combined, the two contracts represent $2 billion in committed cloud revenue from customers Akamai did not have two years ago.

The Concentration Risk

The deal transforms Akamai’s business profile, but concentrates risk in equal measure. If Anthropic’s growth plateaus or if the company follows through on reported plans to develop proprietary AI chips, seven years of committed spend starts to look different. The market’s 27% one-day move is a bet that the growth trajectory holds through 2033.

For Anthropic, the strategic logic is simpler: lock in capacity at current prices during a supply crunch. The company is also reportedly pursuing a funding round that could value it at $850-900 billion. Amazon and Google have invested billions and provide infrastructure, which creates vendor dependency Anthropic is explicitly working to dilute.

The Akamai deal’s first financial impact appears in Akamai’s Q4 2026 filings.
