Akamai Technologies recorded its biggest single-day stock move in more than 22 years on Friday, closing up approximately 27% at $148.38 after the company disclosed a landmark $1.8 billion, seven-year cloud infrastructure commitment from an unnamed frontier AI model provider that Bloomberg subsequently identified as Anthropic, the company behind the Claude family of AI models.
The revelation transformed what would have been a routine quarterly earnings release into one of the most significant contract announcements in Akamai’s 28-year history.
Chief executive Tom Leighton described the agreement as the largest in the company’s existence during the earnings call, telling investors it validates Akamai’s strategic repositioning from a content delivery network into a serious player in AI cloud infrastructure.
First-quarter results for the period ended March 31, 2026, were broadly in line with analyst expectations. Revenue reached $1.074 billion, up 6% year-on-year, while adjusted earnings per share came in at $1.61, matching consensus forecasts precisely.
The headline numbers were unremarkable by themselves, but the composition of that growth told a more compelling story. Cloud Infrastructure Services revenue surged 40% year-on-year to $95 million, with the AI deal set to amplify that trajectory materially in the coming quarters.
Revenue from the Anthropic commitment is expected to begin flowing from the fourth quarter of 2026, contributing an estimated $20 million to $25 million to that quarter’s results. At full ramp, the seven-year deal will represent close to 6% of Akamai’s full-year revenue at current guidance levels, a meaningful concentration for a single customer relationship but one that investors appear to have received as a validation rather than a risk.
The Anthropic dimension adds further context to the deal’s significance. Dario Amodei, Anthropic’s chief executive, had separately disclosed to developers that the company experienced 80-times growth in annualised revenue and usage during the first quarter of 2026 and described the organisation as working “as quickly as possible” to bring additional computing resources online.
That framing positions the Akamai contract as one component of a broader scramble by Anthropic to secure capacity in a market where AI compute demand has consistently outpaced supply.
Akamai has now signed a $200 million Cloud Infrastructure Services agreement with a separate US technology company earlier in the year in addition to the Anthropic deal, suggesting the company’s pivot toward AI workload hosting is generating commercial traction well beyond any single counterparty.
For the second quarter, Akamai guided adjusted earnings of $1.45 to $1.65 per share on revenue of $1.075 billion to $1.1 billion, broadly meeting analyst expectations. Full-year 2026 guidance was set at adjusted earnings of $6.40 to $7.15 per share on revenue of $4.45 billion to $4.55 billion, with the revenue midpoint of $4.5 billion slightly above the $4.48 billion analysts had projected.
Akamai [NASDAQ: AKAM] shares had already gained around 65% over the prior 12 months before Friday’s surge, reflecting investor appetite for companies with credible infrastructure exposure to the AI build-out cycle. With a seven-year contracted revenue stream from one of the most prominent AI labs in the world now confirmed, the company enters the second half of 2026 with a degree of visibility that few of its peers in the content delivery and edge computing space can match.
Security revenue rose 11% to $590 million in the quarter, while the legacy delivery and cloud applications segment declined 7% to $389 million, underlining the ongoing structural shift in where Akamai’s growth is coming from.
