Marvell shares jump after chipmaker wins spot in S&P 500

June 8, 2026 7:56 AM

June 8 (Reuters) - Marvell Technology shares ‌climbed more ​than 9% ​on Monday after the chipmaker was set to join the benchmark S&P 500 at the end of June, in the latest ‌boost to a stock that has surged recently.

Its shares have ⁠gained about 59% since May 27 after the company forecast its custom-chip business would surpass $10 ‌billion in revenue in fiscal ‌2029 and Nvidia CEO Jensen Huang called Marvell the next "trillion-dollar company."

The stock dropped 16.7% in regular trading on Friday amid a broader selloff that ​wiped out $1.3 trillion in market value for the chip sector. The company had a market value of about $230 billion as of last close.

Marvell and ⁠larger rival Broadcom design tailor-made chips for cloud companies' data centers, a market that has boomed as ​major technology firms seek alternatives to Nvidia's expensive and hard-to-source AI processors.

S&P Dow Jones Indices said late on Friday that ​Marvell will replace swimming pool equipment distributor Pool ‌Corp in the benchmark index. The changes will take effect before markets open on June 22.

Exchange-traded funds that track ⁠an index must adjust their portfolios to reflect any changes, requiring them to buy shares of newly added companies, a shift that can lift such stocks as fresh ⁠passive inflows come in around the time of inclusion.

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

Marvell's addition underscores how the ‌AI surge is reshaping major U.S. stock indexes. Chipmakers and data-center infrastructure firms are claiming bigger benchmark weighting on ‌the back of strong investor conviction.

Chip stocks remain higher, despite Friday's slump, with the ⁠broader Philadelphia Semiconductor Index up ‌more than 72% so ​far this year. Marvell has more than tripled in value to hit record highs.
