S&P 500 Adds Another AI Giant: Marvell Technology Set to Join Index, Jumps 9% Premarket

TradingKey - AI chipmaker Marvell Technology ( MRVL) officially announced it will be included in the S&P 500 Index, with the stock rising nearly 9% in pre-market trading on Monday.

Founded in 1995 and headquartered in Santa Clara, California, Marvell Technology currently has a market capitalization exceeding $230 billion. The company specializes in high-performance chip R&D, with products widely used in cutting-edge sectors such as cloud computing, AI, enterprise networking, 5G communications, and automotive systems. Its inclusion in the S&P 500 marks the semiconductor firm's official entry into the ranks of the top 500 U.S. listed companies, reflecting broad market recognition of the robust growth momentum in its AI chip business.

As a core participant in AI infrastructure, the company's data center business has experienced explosive growth in recent years. Its newly released Q1 FY2026 earnings report shows revenue of $2.4 billion, exceeding the consensus estimate of market analysts. Management stated that strong demand from AI data centers for high-speed networking chips and custom computing chips continues to drive the company's business growth.

Notably, Marvell Technology's inclusion is widely seen by the market as a natural progression. The company's market cap has climbed to $230 billion, significantly exceeding the minimum market cap requirement of $22 billion for the S&P 500 Index.

Stephens analyst Melissa Roberts pointed out that Marvell's average market cap has consistently remained above $50 billion over the past year. This data provides strong evidence that its market value growth is not short-term hype but is based on solid business performance.

Inclusion in the S&P 500 means that Marvell Technology's stock will reach a broader range of investors, including passive funds tracking the index and actively managed funds with investment scope restrictions.

Market analysts noted that because a large number of passive funds and ETF products track the S&P 500, newly included companies typically receive passive capital inflows from index funds. This is of material significance for enhancing Marvell Technology's stock liquidity and valuation.

Just last week, Marvell Technology also received a public endorsement from Nvidia ( NVDA) CEO Jensen Huang. During Computex Taipei, Huang shared the stage with Marvell CEO Matthew Murphy, publicly praising Marvell as having the potential to become the "next trillion-dollar company."

In March of this year, Nvidia announced a $2 billion investment in Marvell Technology. The collaboration between the two parties will help customers more easily build AI infrastructure systems. This partnership not only further consolidates Marvell's market position in the AI chip sector but also injects strong momentum into its future development.

As AI technology continues to evolve, AI chips are transforming from traditional secondary roles into core components of AI infrastructure. With its deep expertise in high-performance chips and keen insight into the AI era, Marvell Technology is at the forefront of this industry transformation.
