NVIDIA’s $2 billion investment in Marvell Technology has turned into one of the market’s loudest AI trades of the year. Since March 31, Marvell shares have climbed nearly 131%, while NVIDIA stock has also gained more than 29% as investors reassess both names.
The move matters now because Wall Street is still trying to decide whether the faster rerating belongs to Marvell or to NVIDIA. Marvell is trading around $228.46, about 28% below its 52-week high in June, but its one-year target of $245.94 implies only 7.77% upside from here. NVIDIA, by contrast, carries a one-year target of $305.94, which points to more than 36% upside. For investors searching Avgo today, that comparison has become the point.
The investment was announced on March 31 and was followed by a 12.42% one-day jump in Marvell shares. The reaction was not just about cash. It tied Marvell more closely to NVIDIA’s AI factory and AI-RAN ecosystem through NVLink Fusion, which is designed to let custom silicon from partners work with NVIDIA’s GPU infrastructure at rack scale. The partnership targets custom XPUs, NVLink Fusion-compatible networking and silicon photonics for 5G/6G AI-RAN deployments, giving Marvell a clearer role in the hardware stack that supports AI infrastructure.
Joel South, who has more than 15 years of experience as an investor and financial journalist, said the market is rewarding the stock that looks most directly attached to the next phase of AI buildout, but it has not stopped treating NVIDIA as the cleaner upside story. That is where the friction sits. Marvell’s consensus rating from 37 analysts is Moderate Buy, and the company’s full fiscal year 2026 revenue of $8.195 billion shows a business already anchored by data center demand, with that segment accounting for 73% of sales. Yet the rest of the business still depends on areas outside data center, and the company’s revenue remains heavily tied to a small number of hyperscalers, leaving it exposed if cloud capex cools.
Marvell also has 50+ new opportunities across 10+ customers in custom AI design activity, which supports the long-term case for the stock. But analysts are not chasing the same upside they see in NVIDIA, where 51 of the 53 analysts covering the stock assign it a Buy rating. That split leaves the market with an awkward message: the company that surged nearly 131% after NVIDIA’s investment is still not the one analysts think has the bigger runway. Investors now want to see whether NVLink Fusion design wins and Q1 FY2027 guidance can justify a richer path for Marvell, or whether the larger reward remains with NVIDIA itself.
