Marvell Technology, Inc. (NASDAQ: MRVL) was added to the S&P 500 index effective June 22, 2026, a move that sent the stock up 10.4 % at the open. The inclusion follows a series of events that have driven Marvell’s share price higher in recent weeks.

The announcement was accompanied by a 14‑15 % jump in the stock price on the day the market learned of the change. According to Reuters, the shares were up 210 % year‑to‑date, a gain that has attracted attention from portfolio managers and institutional investors.

A key catalyst for the rally was Nvidia’s $2 billion investment announced on March 31, 2026. The deal, disclosed in a joint press release, creates a partnership that integrates Marvell’s custom AI chips and networking products with Nvidia’s AI infrastructure through NVLink Fusion and silicon photonics. Shares of Marvell rose nearly 13 % after the announcement, reflecting the market’s reaction to the partnership.

Marvell’s first‑quarter fiscal 2026 results, released in early May, showed revenue of $2.4 billion, exceeding consensus estimates. The company also issued guidance that points to higher revenue, driven by its data‑center business. The company’s focus on infrastructure‑level chips for AI, cloud, enterprise networking, 5G, and automotive markets is highlighted in the earnings report.

The S&P 500 inclusion is significant because it obliges passive index funds to buy the stock, creating a structural demand that can support the share price independent of market sentiment. The move also places Marvell among a group of companies that collectively account for a large portion of the U.S. equity market.

Marvell’s headquarters are in Santa Clara, California, and the company was founded in 1995. As of 2026 it employs approximately 7,500 people and holds more than 10,000 patents worldwide. According to its Wikipedia entry, the company reported an annual revenue of $8.2 billion for fiscal 2026.

The partnership with Nvidia is part of a broader trend of AI‑related infrastructure investment. Nvidia’s CEO, Jensen Huang, has been a prominent figure in the AI boom, and the company’s recent investments in silicon photonics and AI chips underscore its strategy to support the growing demand for AI compute.

Analysts note that Marvell’s focus on the “pipes” of the AI economy—high‑performance networking and data‑center chips—positions it to benefit from the continued expansion of AI workloads. The company’s guidance for the next quarter, which points to higher revenue, suggests that demand for its products remains strong.

At present, Marvell’s stock is trading above its 52‑week high, and the company is scheduled to report fiscal second‑quarter results on July 27, 2026. Investors will be watching the company’s data‑center revenue figures and guidance for the remainder of the fiscal year. The S&P 500 inclusion and Nvidia partnership are likely to remain key factors influencing the stock’s valuation.

In summary, Marvell’s addition to the S&P 500, combined with a substantial investment from Nvidia and strong first‑quarter earnings, has positioned the company as a notable player in the AI infrastructure space. The next earnings release will provide further insight into the company’s growth trajectory and the impact of its partnership with Nvidia.
