Marvell Technology to join S&P 500 on June 22, shares jump after news
The chipmaker will replace Pool Corp after meeting S&P 500 profitability criteria, a change expected to drive passive fund buying as AI-linked companies gain more weight in the benchmark.
Fact Check
Multiple corroborating sources confirm the claim. The Kobeissi Letter post (the source link in the input) reports MRVL surging over 7% on S&P 500 inclusion news. WOLF Financial and many other X posts on June 5, 2026 confirm S&P DJI officially announced Marvell and Flex will be added to the index before market open on June 22, 2026, replacing Pool Corp and Campbell Soup. MarketWatch had reported one day earlier that the announcement was expected Friday and Marvell was the leading candidate due to its explosive 2026 stock surge tied to AI infrastructure demand. The price reaction and index-inclusion event are both well documented.
