Generac Holdings shares surged more than 40% in after-hours trading after announcing a long-term partnership to supply backup power systems for Amazon data centers. The initial commitment is valued at about $2.4 billion, with potential aggregate payments of up to $8 billion to Generac and its global affiliates. Amazon received warrants to purchase up to 1.69 million Generac shares, with vesting tied largely to qualifying purchases. The agreement highlights the growing demand for reliable power infrastructure as artificial-intelligence data centers expand. Intel shares also advanced amid reports that SK Hynix is considering leasing space at Intel's Ohio fabrication facility or forming a joint venture, although no agreement has been finalized. Lucid Group gained about 5.5% in premarket trading after announcing a partnership with Bolt to deploy at least 25,000 autonomous electric vehicles across Europe using Lucid's forthcoming Midsize platform and Nvidia's Hyperion technology. Nvidia rose more than 2% as technology stocks benefited from lower long-term Treasury yields and softer oil prices, while Nebius raised prices for access to some Nvidia processors. The Federal Reserve unanimously raised its benchmark rate by 25 basis points to a 3.75%-4.00% target range, its first increase since 2023; 16 of 18 policymakers projected at least one further increase before year-end.
