Akamai agrees to provide cloud computing services to Anthropic under a multi-year contract, and the announcement is followed by a sharp rise in Akamai’s stock, as reported by MarketWatch and Quartz.

Quartz and MarketWatch both describe the deal as large and significant, with Quartz adding more detail on structure and potential size. The agreement is set for seven years and is described as starting around $12 billion, with an ability for the total value to rise to as much as $20 billion depending on scope. Quartz also says the terms include a warrant that could allow Anthropic to buy up to 5% of Akamai stock.

Both outlets frame the transaction as strengthening Akamai’s role in cloud-related services, particularly as Anthropic becomes a key customer. Differences are mainly in emphasis and specificity: MarketWatch highlights the deal’s market impact and comparative position versus cloud providers, while Quartz focuses on the contract’s duration, potential expansion, and the warrant terms.
