Marvell Stock Soars on Nvidia Praise: Is It Overvalued?

Jun 18, 2026
Bobby Quant Team

💡 Key Takeaway

While Nvidia's endorsement fueled a massive rally, Marvell's current valuation appears stretched, making Nvidia the more compelling AI investment for now.

The Nvidia Endorsement That Lit a Fire

Marvell Technology's stock price skyrocketed more than 40% in June after receiving a stunning public endorsement from Nvidia CEO Jensen Huang. Huang went so far as to suggest Marvell could be on a path to becoming a trillion-dollar company, a bold statement for a firm currently valued around $270 billion.

This surge was fueled by Marvell's key role in the AI infrastructure ecosystem. The company is a critical partner for Nvidia in data centers, providing popular networking and connectivity hardware that ensures Nvidia's powerful chips can communicate effectively.

Interestingly, Marvell also operates as a competitor to Nvidia in one area: it designs custom AI chips called ASICs. These chips are tailored for specific tasks and can be more efficient and cost-effective than Nvidia's general-purpose GPUs for certain workloads.

Nvidia's willingness to praise a company that is both a partner and a potential rival in a core market makes the endorsement particularly noteworthy. It signals a high level of confidence in Marvell's technology and its role in the broader AI build-out.

The rally has pushed Marvell's valuation to new heights, raising immediate questions for investors about whether the stock has run too far, too fast based on this celebrity backing.

Valuation Reality Check in the AI Frenzy

For investors, this story is a classic case of separating compelling narrative from financial reality. A CEO's praise can drive short-term momentum, but long-term returns are dictated by growth, profitability, and price.

Marvell's business is fundamentally strong, with Q1 revenue up 28% year-over-year. However, for a stock priced for hyper-growth in AI, that pace is considered modest. Wall Street expects acceleration, but it may not be enough to justify the current premium.

The core issue is valuation. Following the surge, Marvell trades at a steep 76 times forward earnings estimates. This is more than triple the valuation of Nvidia, which trades at 24 times forward earnings.

This disparity matters because Nvidia is the undisputed leader in AI compute, with massive scale and profitability. Paying such a high premium for a smaller player like Marvell requires near-perfect execution and growth for years to come.

Ultimately, the news matters because it highlights the euphoria and potential froth in secondary AI stocks. While the partnership is real and beneficial, the market's reaction may have gotten ahead of the company's near-term financial prospects, creating a risky entry point for new investors.

Avoid chasing MRVL after its massive run; investors seeking AI exposure should favor the leader, NVDA, at its more reasonable valuation.

The endorsement is positive, but the stock's reaction has been extreme. At 76x forward earnings, MRVL needs flawless, hyper-fast growth for years to even approach its trillion-dollar hype, which is a high-risk bet. NVDA offers a better risk/reward profile as the profitable ecosystem anchor.

If you hold MRVL, consider taking some profits off the table after this sentiment-driven surge, as the valuation looks vulnerable if growth disappoints. Investors with exposure to the AI semiconductor sector should note that this event highlights the extreme valuations of some secondary players compared to the leader. Broad AI ETF holders may see volatility as the market grapples with these valuation disparities.

MRVL
Negative
The stock's 40% surge on Nvidia's endorsement appears to have fully priced in the positive news, leaving it trading at a demanding 76x forward earnings with growth that may not justify the premium.
NVDA
Positive
Positioned as the superior, more reasonably valued AI investment at 24x forward earnings. Its endorsement power also reinforces its central, kingmaker role in the ecosystem.
