U.S. AI-linked and optical communications stocks close broadly higher, led by Intel and Marvell
Wall Street’s main indexes finished mixed, while Nvidia-associated names including Intel, Marvell, IREN, Coherent, Corning, Lumentum and CoreWeave posted gains.
Fact Check
CNBC's premarket movers article directly confirms Marvell Technology was up 9% premarket on June 8, 2026 due to S&P 500 inclusion, matching the claim's headline figure. A separate CNBC article on the Marvell S&P 500 addition reports a ~10% jump, and Reuters reports 7.2% premarket — bracketing the >9% figure. CNBC also confirms Corning rose ~4% on an Amazon AI data center deal the same day, consistent with the claim's ~3% figure. While the exact premarket percentages for POET, AAOI, and Credo could not be independently verified from primary outlets, the broader optical-communications rally context aligns with Marvell's surge and these stocks frequently move sympathetically. The headline claim is well-supported.
Summary
U.S. stocks closed mixed, with the Dow Jones Industrial Average down 0.16%, the S&P 500 up 0.30% and the Nasdaq rising 0.86%. A basket of Nvidia-associated names finished broadly higher, led by Intel, which gained 11.19%, and Marvell, up 9.63%. IREN rose 8.91%, Coherent added 6.62%, Corning advanced 5.61%, Lumentum climbed 3.68% and CoreWeave gained 1.97%. The latest move updates earlier premarket strength in optical communications shares and shows the rally carried into the close for several AI infrastructure and networking-related stocks.
