Akamai Technologies shares jumped more than 20% Friday after Anthropic formalized a seven-year, $11.6 billion agreement to secure CPU computing capacity through Akamai Cloud for artificial intelligence workloads. Expansion provisions could add another $9 billion, bringing the potential commitment close to $20 billion, while warrants could eventually convert into as much as 5% of Akamai's common stock. The deal strengthens Akamai's position in the AI infrastructure market beyond its traditional content-delivery and cybersecurity businesses. U.S. stocks also rose as AI enthusiasm offset 10-year Treasury yields above 5%; the Dow gained 0.93% to 51,828.62, the S&P 500 rose 0.51% to 7,743.41 and the Nasdaq added about 0.48%. Marvell gained 1.15% to $261.94 as demand for data-center networking, optical interconnects and custom silicon continued to support its AI infrastructure business.
