Akamai will spend an estimated $5.5 billion building out compute capacity for Anthropic under a seven-year, $11.6 billion contract signed Sept. 24 -- the largest deal in Akamai's history, on top of a $1.8 billion contract the two companies signed earlier in 2026. The commitment can grow to roughly $20 billion if Anthropic keeps buying. What makes it unusual isn't the size -- multi-billion-dollar AI compute contracts are routine now -- it's who paid whom in equity. Akamai is handing Anthropic a warrant for up to 5% of its own stock. The vendor is compensating the customer, not the other way around.
The terms, filed with the SEC in an Akamai 8-K exhibit, are specific down to the vesting schedule. The base commitment immediately vests a warrant covering about 2% of Akamai's stock on an as-converted basis; each additional $3 billion Anthropic actually purchases beyond that -- up to $9 billion more -- vests roughly one more percentage point, capping the total at 5%, or about 7.7 million shares, exercisable at $111.33 apiece.
"Anthropic is advancing the AI revolution and we are thrilled they chose Akamai's capabilities for building and operating AI infrastructure at scale." -- Tom Leighton, Akamai co-founder and CEO
Akamai isn't a GPU cloud. Its business for two decades has been content delivery -- caching and routing internet traffic from thousands of points of presence close to end users, not training frontier models inside a handful of hyperscale campuses. The company's own language for what it's selling here is telling: 'compute from core to edge,' for Anthropic's CPU workload growth. Neither company has said publicly which of Claude's workloads that covers -- inference serving close to users is the obvious guess, given Akamai's edge footprint, but the release doesn't say so directly, and the honest answer is that detail isn't public yet.
What the $11.6 billion actually covers
Akamai's own numbers span several different things that are easy to blur into one headline figure. Here's what each one is, and isn't:
What the $11.6 billion Akamai deal covers, and what it doesn't
- $11.6B · 7-year term
- Committed CPU-compute purchase, Anthropic to Akamai
Includes: The base contractual commitment Akamai calls its largest deal ever, on top of a $1.8B contract the two signed earlier in 2026.
Excludes: The separate $9B expansion option -- not yet spent, not yet owed. - $9B · expansion option
- Additional purchases Anthropic could make, not yet committed
Includes: The ceiling that would bring the relationship to roughly $20B total.
Excludes: Any obligation -- Anthropic can decline it entirely, and nothing vests if it does. - $5.5B · Akamai's own capex
- What Akamai expects to spend building the capacity
Includes: Akamai's own estimate of its build-out cost tied to the $11.6B commitment -- more than six times its total 2025 capital spending.
Excludes: Revenue -- Akamai says the deal has no impact on 2026 revenue. - $1.7B · 2026 capex increase
- Akamai's separately guided rise in 2026 capital spending
Includes: Supply-chain components, including memory, tied to the broader buildout.
Excludes: A stated breakdown of how much of this sits inside the $5.5B figure versus alongside it -- Akamai's disclosures don't specify. - 5% · warrant, capped
- Maximum stake Anthropic can earn in Akamai
Includes: 7.7 million shares on an as-converted basis, exercisable at $111.33 each.
Excludes: Any cash payment from Akamai to Anthropic -- the entire consideration is equity, contingent on spending.
The gap between what Akamai is spending and what it expects to collect this year is the deal's real risk, not its size. The company's own estimate for building this out -- $5.5 billion -- is more than six times what Akamai spent on capital expenditures in all of 2025, and separately, Akamai's total 2026 capex guidance is rising by about $1.7 billion for supply-chain components, including memory. Akamai's own guidance says none of it moves 2026 revenue -- the infrastructure gets built well before Anthropic's payments catch up to it, and Akamai is carrying that gap on its own balance sheet in the meantime.
The vesting math, run for yourself
The mechanism is unusually legible for the kind of arithmetic that normally needs an analyst deck to reconstruct -- Akamai's own filing states the exchange rate outright: about one percentage point of the company for every $3 billion Anthropic spends past its initial commitment.

How Wall Street read it
Akamai's stock actually fell 6.8% the day the deal was announced after-hours Thursday, then swung hard the other direction Friday as the market had a full session to digest the terms. How hard depends on which snapshot you read -- outlets measured the same trading day at different moments and got different numbers:
Three analysts raised their price targets the same day, including J.P. Morgan Securities, up to $167 from $158. Some of the pop is plausibly mechanical rather than a fresh read on the deal's value: 19.02 million shares -- about 13.5% of Akamai's float -- were sold short heading into the announcement, a setup where a positive surprise can force short sellers to buy back stock and amplify the move.
The direction these deals usually run
Akamai paying Anthropic in equity isn't unprecedented, but it isn't the more common pattern either. AMD granted OpenAI warrants to buy its stock as part of a chips deal -- the same vendor-to-customer direction Akamai just used. (OpenAI has separately become one of AMD's largest shareholders through that arrangement.) The more familiar shape runs the other way: Anthropic's own November 2025 deal had Microsoft and Nvidia investing a combined $15 billion directly into Anthropic itself -- $10 billion and $5 billion respectively, at a $350 billion valuation -- in exchange for Anthropic committing $30 billion of Azure compute plus gigawatt-scale Nvidia hardware purchases. That's the customer's vendors buying into the customer. Akamai's warrant is the customer's vendor being paid by the customer's own future spending, in the vendor's stock instead of the customer's.
None of that makes the demand fake -- Akamai calls this the largest contract in the company's history, and the SEC filing puts a real, checkable vesting schedule behind it rather than a vague number in a press release. It does mean the 14% pop and the $20 billion headline are measuring two different things: one is a dated, mechanically verifiable contract; the other is Wall Street pricing in continued expansion Anthropic hasn't actually committed to yet.
- Akamai will supply Anthropic $11.6 billion of CPU compute over seven years, expandable to $20 billion.
- Akamai's largest deal ever, on top of a $1.8 billion contract the two signed earlier in 2026.
- Akamai pays Anthropic in stock: a warrant for up to 5% of shares, not a price discount.
- Akamai's stock closed up 14.2% on the news; heavy short interest complicates how durable that is.
- Caveat: Akamai says the deal won't move 2026 revenue -- the spending lands well before it does.
