Akamai’s cloud infrastructure deal with Anthropic gave the provider a 27% jump — its best day in 28 years

Akamai Technologies has signed a seven-year contract worth $1.8 billion with a company it did not name in its official press release, but Bloomberg quickly identified as Anthropic. This is one of the largest AI companies, a direct competitor to OpenAI in the development of large language models. The contract is the largest in Akamai's 28-year history and the first public disclosure of its real partner in the race for cloud infrastructure for AI. The news triggered a strong market reaction.

Who was hidden behind

Akamai's "leading frontier model provider"

In its official announcement, Akamai described its partner as a "leading frontier model provider," but sources immediately pointed to Anthropic. The company was founded in 2021 by former OpenAI employees, including Dario Amodei (currently CEO), his wife Daniela, and Sam Altman's sister. Since then, Anthropic has released the Claude family of models, which are rapidly gaining market share. The contract implies the delivery of comprehensive cloud infrastructure necessary for training and deploying models at Claude's level. The seven-year term indicates a long-term strategic partnership rather than a one-off deal. During this period, Akamai will provide computing resources, network infrastructure, distributed storage, and global traffic distribution to serve millions of Claude users.

Stock growth at 28-year maximum

When the news broke, Akamai's stock rose 27% in a single trading session — the best result in the company's history. For context: Akamai was founded in 1998 and over three decades has survived the internet boom, the dot-com crash, recovery, and competition with cloud giants Amazon, Google, and Microsoft. But it has never seen such jumps before. The market reacted to the news as a turning point. This reflects several key signals to investors:

• Demand for cloud infrastructure for AI is real and long-term, not a bubble
• Akamai has secured predictable revenue for seven years ahead
• This is recognition that Akamai remains a critically important player
• Infrastructure providers are winning in the AI race no less than model creators

Infrastructure as the main value

For many years, companies tried not to disclose their strategic partners when it came to critically important infrastructure. The fact that Akamai publicly (albeit indirectly) announced its partnership with Anthropic suggests that AI infrastructure is becoming mainstream, not a secret weapon. Behind this deal is simple, but increasingly expensive math: training a large language model requires petabytes of computing, exabytes of traffic, guaranteed reliability, and global reach. No model creator can do without specialized providers like Akamai, AWS, Google Cloud, or OCI. This creates a stable, growing market for auxiliary infrastructure.

What it means

The Akamai and Anthropic deal is not just a large contract. It's a signal that the AI race is moving from theory to real, long-term agreements with predictable revenue. Cloud providers and specialized infrastructure suppliers are becoming the main winners in the AI business — often not the model creators themselves, but their resource and tool suppliers.
