Marvell to join S&P 500 after AI boom helps chipmaker pass profitability test

Marvell Technology is set to join the benchmark S&P 500 later this month, S&P Dow Jones Indices said on Friday, after the chipmaker cleared a key profitability hurdle riding an AI-fueled rally.

The company will replace swimming pool equipment distributor PoolCorp on the benchmark index before the start of trading on ‌June 22. Marvell ⁠shares ⁠jumped nearly 6% in extended trading.

The inclusion comes after the company reported a GAAP ​profit in the three months through December and over the sum of its ​most recent four quarters, overcoming a key barrier that had previously kept it out.


Marvell's shares have more than tripled so far this year, ​bolstered by a broader rally in chip stocks ⁠on hopes ‌for robust AI-related demand.

This week alone its shares have gained roughly 29%, partly due to Nvidia CEO Jensen Huang ⁠calling the chipmaker the "next trillion dollar company". The company's market value was $276.81 billion, as of Friday's close.

Marvell and larger rival Broadcom design custom chips for cloud-computing companies' specific data-center needs, a business that has grown rapidly as Big Tech looks to reduce reliance on Nvidia's costly and supply-constrained AI processors.

In its most recent quarterly earnings, Marvell forecast its custom chip business would ‌surpass $10 billion in revenue in fiscal 2029.

Its inclusion in S&P 500 reflects how the AI boom is reshaping major U.S. equity benchmarks, with chip and ⁠data-center infrastructure companies commanding increasingly large weights as investors bet on sustained demand from cloud providers and AI workloads.

The move would trigger buying from ​index funds and ETFs that track the S&P 500, as passive managers are required to hold constituents in line with their benchmark weights.

Separately, contract manufacturer Flex will also be added to the index, replacing packaged food company Campbell's.
