Marvell Technology is set to be added to the S&P 500 index on June 22, replacing PoolCorp, after clearing a key profitability requirement fueled by rising demand linked to artificial intelligence applications.
- Marvell replaces PoolCorp in S&P 500 on June 22
- Shares rose nearly 6% in after-hours trading
- Forecasts custom chip revenue over $10 billion by fiscal 2029
What happened
Marvell Technology will officially join the S&P 500 index on June 22, following the company’s successful demonstration of sustained profitability, a key criterion for addition to the benchmark. The chipmaker outperformed expectations, reporting GAAP profits in the recent quarter and cumulatively over the last four quarters, a threshold it previously had not met. The move will see Marvell replace PoolCorp, a distributor in a completely different sector.
This announcement triggered a nearly 6% jump in Marvell’s shares during after-hours trading, reflecting the market’s positive reception. The stock has surged over 200% so far in 2026 amid a wave of enthusiasm for semiconductor stocks tied to increasing artificial intelligence workloads and cloud infrastructure demand.
Why it matters
Marvell’s ascent into the S&P 500 highlights how the AI boom is reshaping major U.S. equity indices by elevating companies that supply custom chips for cloud computing and data centers. These sectors are critical as large technology firms seek more tailored alternatives to Nvidia’s expensive and limited AI processors, thereby boosting companies like Marvell and Broadcom.
Inclusion in the S&P 500 also brings tangible financial effects, as many index funds and ETFs must purchase shares to mirror the index’s holdings, potentially adding to Marvell’s stock momentum. It underscores investor confidence in the company’s long-term growth potential driven by AI and cloud demand.
What to watch next
Investors and analysts will be monitoring Marvell’s trajectory toward its fiscal 2029 revenue target of over $10 billion from its custom chip business. Achieving this would confirm the company’s status as a major player enabling the cloud and AI ecosystem, potentially driving further stock appreciation and market share gains.
Additionally, the impact of Marvell’s S&P 500 inclusion on index funds and ETFs will be observed closely, as buying pressure could influence short-term price movements. Stakeholders will also watch how competitors like Broadcom respond to intensifying competition within this high-growth space.
