The April 2026 scoreboard for AI infrastructure stocks is in, and the gap between the leaders is wider than most expected. Marvell Technology (NASDAQ:MRVL | MRVL Price Prediction) stock ran away with the month, posting a 67% gain from the March 31 close of $99 to the April 30 close of $165.15.
Arm Holdings (NASDAQ:ARM) stock finished second with a 39% April advance, climbing from $151.28 to $210.32. Vertiv (NYSE:VRT) stock took third at 31%, moving from $250.58 to $328.49.
All three rode the same artificial intelligence (AI) capital expenditure (CapEx) wave, but different business models translated that tailwind into very different April returns. The scoreboard hints at which approach converts AI spending into shareholder gains fastest.
Three Different Business Models
There’s an AI-tech connection here, but these are three distinct businesses addressing different niches. Marvell designs custom application-specific integrated circuits (ASICs) for hyperscalers and high-bandwidth data center networking silicon. Arm licenses central processing unit (CPU) architecture intellectual property (IP) to chip designers.
Meanwhile, Vertiv sells power and thermal management gear for data centers, a direct hardware beneficiary of dense graphics processing unit (GPU) deployments. The Vertiv model converts AI demand to revenue through longer product cycles than ASIC volume ramps.
Why Marvell Won April
Marvell’s win came from custom silicon programs converting from design wins to volume production. The Google TPU partnership narrative caught fire on April 19, when Reddit’s WallStreetBets surfaced reporting that “Google in talks with Marvell to build new AI chips for TPUs, aiming to rival Nvidia GPUs.”
That post drew 534 upvotes and 92 comments, and Marvell sentiment hit very bullish readings of 85 to 86 earlier in the month. CEO Matt Murphy has framed the company as “uniquely positioned at the center of this transformation” as the industry shifts to custom AI infrastructure.
Marvell’s last reported quarter showed data center revenue up 76% year-over-year (YoY) to $1.44 billion, reinforcing the ASIC volume thesis. The result underscores how custom silicon volumes are scaling alongside hyperscaler deployments.
Why Arm Came in Second
Arm benefits from the same hyperscaler custom silicon trend, but indirectly. Every Graviton, Cobalt, or Grace chip that ships pays Arm a royalty, yet the IP model captures less per dollar of silicon than direct ASIC design work.
Arm’s last filed quarter showed royalty revenue of $737 million, up 27% YoY, with Armv9 adoption and AI demand as the cited drivers. The royalty model produces beautiful operating leverage, but the revenue capture lags the immediate volume ramp at ASIC designers.
Year-to-date (YTD) through April 30, ARM stock gained 92.41%, nearly matching Marvell’s pace over the longer window. The royalty engine continues to compound even when monthly performance trails peers.
Why Vertiv Was Third
Vertiv’s third-place April finish disguises an enormous year. Vertiv stock is up 256% over one year and 103% YTD, so April’s 31% gain partly reflects digestion after extreme outperformance.
Q1 2026 results, filed April 22, were strong. Vertiv reported adjusted earnings per share of $1.17 against a $1.01 consensus, revenue of $2.65 billion (up 30.1% YoY), and Americas organic sales up 44%.
Vertiv’s management raised the full-year outlook to $13.5 billion to $14 billion in net sales with adjusted EPS of $6.30 to $6.40. CEO Giordano Albertazzi noted Vertiv is “positioned to be the partner customers need to bring their most ambitious projects to life, at scale.” The story is intact, but VRT’s product cycle converts to revenue more slowly than ASIC shipments.
What to Watch in May
Investors should watch hyperscaler capex commentary on Q1 calls, Marvell’s next update on custom silicon design win conversion, Arm’s royalty growth metrics, and Vertiv’s deployment data. Prudent investors may consider moderate position sizing rather than chasing Marvell stock after a 67% month.
Keep an eye on whether MRVL stock can hold its April gains as the late-month Reddit sentiment turned bearish on April 28. The next major catalyst will likely be the cluster of hyperscaler earnings reports through early May.
