Akamai Signed an $11.6 Billion Contract With Anthropic. Its Stock Jumped 20% in After-Hours Trading.

Akamai Technologies signed an $11.6 billion, seven-year computing agreement with Anthropic on Thursday, and its stock responded by jumping more than 20% in after-hours trading. Wall Street doesn't usually reward a content delivery network with that kind of pop for a services contract. But Akamai isn't really pitching itself as a CDN company anymore.

What Changed

The core commitment is $11.6 billion in CPU workloads, delivered through Akamai's globally distributed network of thousands of points of presence. Anthropic can add up to $9 billion more under an expansion option, which would push the total toward $20 billion over the life of the contract. Akamai says the buildout tied directly to this deal will cost roughly $5.5 billion in capital expenditures, on top of about $1.7 billion in additional 2026 spending meant to secure supply chain components before they get scarcer.

There's an equity piece too. Anthropic received warrants convertible into up to approximately 5% of Akamai's common stock, exercisable at $111.33 a share. Roughly 2% vests immediately, and the rest vests in increments tied to every additional $3 billion Anthropic commits under the contract. That structure ties Akamai's upside directly to how much compute Anthropic actually consumes, not just to the signature on the press release.

Akamai co-founder and CEO Tom Leighton said Anthropic chose Akamai's capabilities for building and operating AI infrastructure at scale. Akamai, notably, said the deal won't change its 2026 revenue guidance, a reminder that a multi-year commitment and near-term reported revenue are two different things. Cloud Infrastructure Services revenue came in at $99 million in the second quarter, up 39% year-over-year. This one contract, phased over seven years, is worth more than a decade of that current run rate.

Why It Matters

Anthropic has been actively diversifying who it buys compute from, and that pattern matters more than any single contract. In May, Akamai and Anthropic signed a smaller $1.8 billion agreement. This new deal is roughly six times that size four months later. Anthropic has also locked in a 20-year lease for 401 megawatts of power capacity at TeraWulf and struck supply agreements with Micron, whose stock has become a bellwether for the AI-driven memory chip supercycle.

Spreading commitments across multiple suppliers, rather than concentrating spend with one or two hyperscalers, gives an AI lab negotiating leverage and some insulation if a single vendor hits capacity constraints. Microsoft has run into exactly that kind of crunch, renting Amazon's cloud capacity just to keep some of its own services online while it builds toward a longer-term buildout target. Anthropic appears to be trying to avoid ending up on the wrong side of that dynamic.

The warrant structure fits a broader pattern taking shape across AI infrastructure deals this year. Nvidia has built a web of financing, investment, and supply arrangements with more than a dozen AI companies, some of which route its own capital back to itself as reported revenue. Akamai's warrants work differently, since Anthropic isn't handing Akamai cash upfront, but the underlying logic rhymes: equity and future revenue commitments are becoming as central to these contracts as the dollar figure in the headline.

What to Watch Next

Whether Anthropic actually exercises the additional $9 billion option will say a lot about how fast its own compute demand is growing relative to how fast supply comes online. Akamai's next earnings report should show whether Cloud Infrastructure Services revenue accelerates meaningfully beyond that 39% year-over-year pace, and whether the extra $1.7 billion in 2026 capex shows up as firm orders for chips, power, or networking gear. The cost of building a gigawatt of AI data center capacity has been climbing, and Akamai is now underwriting part of that buildout with its own balance sheet in exchange for warrants that only pay off if Anthropic keeps scaling.

Investors will also be watching whether other mid-size infrastructure providers try to strike similar deals. A 20% overnight stock move for landing one customer is a hard signal to ignore, and it raises the bar for what now counts as a credible AI infrastructure story.

The Pulse24 Take

This deal is really about who gets to be an AI compute supplier now that a handful of hyperscalers can't build capacity fast enough on their own. Akamai spent two decades as an unglamorous content delivery network, and now it's underwriting billions in AI infrastructure buildout with an equity stake tied to Anthropic's future spending. Both sides are making a bet: Akamai is betting Anthropic's demand keeps growing, and Anthropic is betting a diversified supplier base beats dependence on one or two giants. Neither bet is guaranteed to pay off, and the market's 20% reaction probably says as much about how starved investors are for AI infrastructure stories outside the usual handful of names as it does about certainty in the outcome. Worth watching whether Cloud Infrastructure Services revenue growth next quarter actually matches the enthusiasm of the stock move.
