Akamai Rents Anthropic Its Spare CPUs

25SEP
$11.6B / 7 YEARSSPARE CPUs5% WARRANT

A twenty-eight-year-old CDN just signed an $11.6 billion, seven-year compute deal. No GPUs involved. Akamai stock jumped 20% after hours.

Anthropic is buying CPU capacity, not accelerators. The work is the unglamorous half of an AI company: data prep, evaluation harnesses, orchestration, serving glue. Akamai already has that hardware in thousands of edge locations.

The structure is the tell. Akamai issued a warrant for 7.7 million shares at $111.33, up to about 5% of common. Roughly 2% vests now. Another 1% vests per additional $3 billion Anthropic spends.

Anthropic holds an option to add $9 billion, taking the deal near $20 billion. Akamai guided 2026 capex up $1.7 billion, mostly pre-buying memory, and left revenue guidance untouched.

full brief & sources

⚡ Why this matters

  • Every compute story this year has been about GPUs. This one says the shortage has moved down the stack to ordinary processors.
  • Warrants tie a supplier's equity to a customer's spend. That is the Nvidia-OpenAI pattern arriving in the boring layer of infrastructure.
  • If Anthropic can rent CPU from a CDN's idle footprint, so can everyone else. Spare capacity in unfashionable places just became a market.

🔍 What happened

  • Akamai announced the agreement on September 24. Seven years, $11.6 billion committed, with an Anthropic option to add $9 billion.
  • The capacity is CPU-based compute across Akamai's distributed platform, not GPU training clusters. Anthropic keeps its GPU footprint with existing partners.
  • Akamai issued Anthropic a warrant for 7.7 million shares as-converted at $111.33 per share, up to roughly 5% of Akamai common. About 2% vests immediately; a further 1% vests for each incremental $3 billion of spend.
  • Akamai put total capex for the buildout near $5.5 billion and raised 2026 capex by about $1.7 billion, largely to pre-purchase memory ahead of price increases. It did not change 2026 revenue guidance.
  • Akamai shares rose about 20% in after-hours trading on the announcement.
  • Context: Anthropic committed about $1.8 billion to Akamai in May 2026, leased roughly 401MW at TeraWulf's Hawesville site, and closed a Series H alongside a Micron memory arrangement.

💬 Smart takes

  • Tom Leighton, Akamai co-founder and CEO: framed the deal as putting Akamai's distributed platform to work for frontier AI, not as a pivot away from delivery and security.
  • The warrant math: Anthropic gets cheap equity upside for being a large customer. Akamai gets a seven-year revenue floor. Both sides are betting the spend keeps climbing.
  • Skeptic: $5.5 billion of capex against revenue guidance that did not move. The cash goes out first and the margin story is a 2027 question.

🧭 Where this goes

  1. Likelyother CDNs and edge networks market spare CPU capacity to labs within two quarters.
  2. PossibleAnthropic exercises the $9 billion option in 2027, pushing Akamai's warrant vesting past 3%.
  3. Wild CardCPU capacity becomes the constrained resource in 2027 and GPU-only providers find they bought the wrong half of the stack.

🥄 The Spoon Take

The interesting number is not $11.6 billion. It is zero GPUs. Frontier labs spend enormous compute on work that never touches an accelerator, and nobody was pricing that. Akamai found revenue in hardware it already owned. Ask what idle capacity your own infrastructure is sitting on.

🤔 Pushback

Warrant-linked supplier deals inflate reported commitments. A seven-year number is a ceiling, not a contract you can bank, and Anthropic can slow its spend without penalty.
