Marvell and Flex Added to S&P 500
Marvell Technology and Flex will be added to the S&P 500 index on June 22, 2026, replacing Pool Corp and The Campbell’s Company. Marvell, a chipmaker supplying components used in AI infrastructure, has received a $2 billion investment from Nvidia and was singled out by Nvidia CEO Jensen Huang as a potential “next trillion‑dollar company.” Flex, a contract electronics manufacturer with customers including Apple and Nvidia, will also join the benchmark. Shares of Marvell and Flex rose in after‑hours trading following the announcement. The change underscores the growing weight of technology and semiconductor firms in major U.S. equity benchmarks and will affect index‑linked funds and passive flows.
Changes to the S&P 500 affect index composition, passive fund flows and visibility for the added companies; the inclusion of an AI-focused chipmaker highlights tech sector influence but is not industry‑shifting for AdTech/MarTech.
