Marvell Technology (MRVL) shares soared 32.5% on Tuesday to a record close of $290.79, propelling its market capitalization to approximately $260 billion. The surge came after Nvidia (NVDA) CEO Jensen Huang publicly identified Marvell as a potential future trillion-dollar company, igniting a rally across the semiconductor sector.
During a keynote at Computex in Taipei, Huang praised Marvell's role in the AI ecosystem, highlighting its custom chip designs and optical networking solutions. The endorsement sent the Philadelphia Semiconductor Index up 5.9%, while the broader Nasdaq Composite remained nearly flat, gaining just 0.03%.
Investors are increasingly rotating capital into lesser-known AI infrastructure plays, particularly those involved in networking chips, optical interconnects, and specialized silicon. These components are critical for managing data flow between servers and processors in large-scale AI cloud projects. Marvell's custom chips and data-movement gear are seen as essential for the next wave of AI spending.
Marvell CEO Matt Murphy joined Huang on stage at Computex, underscoring the deepening partnership between the two companies. Nvidia invested $2 billion in Marvell earlier this year, further validating its strategic importance. Marvell reported a strong fiscal first quarter last week, with revenue rising 28% year-over-year to a record $2.418 billion. The company guided second-quarter revenue to $2.7 billion at the midpoint, citing exceptional AI-related bookings, and raised revenue targets for fiscal 2027 and 2028.
Despite the rally, Marvell still trades well below the trillion-dollar valuation Huang mentioned. To reach that level, the stock would need to multiply several times from current levels. However, the shares are already trading near 100 times earnings, leaving little room for error. Any slowdown in AI orders, delays in custom chip ramps, or margin compression could trigger a sharp reversal.
The broader market saw modest moves on Tuesday. The S&P 500 rose 0.13%, the Dow Jones Industrial Average added 0.45%, but the Nasdaq Composite was nearly flat. The Philadelphia Semiconductor Index's 5.9% gain reflected a massive dispersion within the AI infrastructure trade, as noted by Mike Dickson, head of portfolio management at Horizon Investments.
Broadcom (AVGO) also ended at a record high, as investors anticipate similar benefits from custom silicon and networking demand. The chipmaker is set to report earnings on Wednesday. The move underscores growing bets that AI data-center spending is broadening beyond Nvidia's core processors, with Broadcom seen as a top rival to Marvell in these markets.
Looking ahead, the key risk for Marvell is its elevated valuation. If cloud customers pull back on AI infrastructure spending, or if optical networking margins disappoint, Tuesday's re-rating could reverse quickly. Investors will be watching Broadcom's results and U.S. economic data on Wednesday for clues on whether the chip rally has run too far.
