Marvell Technology Inc. stock climbed nearly 3% on Tuesday, driven by a risk-on session and an updated rating from KeyBanc. Analyst John Vinh maintained an Overweight rating and raised the price target to $400 from $385, citing momentum in the custom AI silicon business. The new target reflects confidence in Marvell's positioning within the data center and artificial intelligence infrastructure markets.

AI Silicon and Design Wins

KeyBanc highlighted specific growth drivers for Marvell, including expectations that Amazon.com Inc. will ramp its Trainium 3 program in the second half of 2026, with Trainium 3 Lite volumes increasing into 2027. Vinh also anticipates Marvell will supply a variant of Amazon’s next-generation Trainium 4 accelerator using network processing offload (NPO) technology.

Additionally, the firm noted a design win for Alphabet Inc.’s Google LPU, codenamed Merope, expected to launch in 2028 or 2029. KeyBanc estimates shipments of 2 million to 3 million units, representing $10 billion to $12 billion in revenue over the program’s lifecycle.

Technical Analysis

Marvell remains in a long-term uptrend, supported by a golden cross formed in October 2025. The stock is trading roughly 30.5% above its 100-day simple moving average and about 74% above its 200-day simple moving average. However, the short-term picture is mixed, with shares trading 16.2% below the 20-day SMA and 4.6% below the 50-day SMA. The MACD remains below its signal line, indicating weakened buying momentum.

Marvell Technology Inc. shares traded higher on Monday following reports of delays and cancellations within Nvidia Corp.'s artificial intelligence hardware roadmap, creating a competitive window for rival custom chipmakers. The stock rose 4.37% to $256.00 during premarket trading, outpacing gains in Nasdaq futures, which were up 1.27%, and S&P 500 futures, which gained 0.47%.

Nvidia's Kyber NVL144 Faces Setbacks

Research firm SemiAnalysis reported on Sunday that Nvidia's Kyber NVL144 architecture faces significant production hurdles. The architecture has reportedly encountered major setbacks just three months after Nvidia CEO Jensen Huang demonstrated it at GTC. SemiAnalysis stated that the launch is now delayed by more than 12 months to 2028. The firm cited manufacturing challenges with the PCB midplane and co-packaged optics (CPO) as primary drivers for the delay.

Alternative Architecture Canceled

SemiAnalysis also noted that Nvidia canceled its proposed alternative, the NVL72x2 back-to-back rack architecture. The design aimed to increase the copper NVLink scale-up size by placing two Oberon racks back-to-back. According to the firm, the project was canceled due to "heavy pushback from CSPs and hyperscalers over its odd design and heavy operational burden."

Market Implications For Competitors

The infrastructure delays leave Nvidia without a proven solution to expand the scale-up world size for its upcoming Rubin Ultra chip. SemiAnalysis noted this creates "a gap for competitors like AMD MI500X or TPUv8i Broadfly to gain scale-up advantages over Rubin Ultra." Additionally, the 4-compute-die Rubin Ultra has reportedly been canceled.

Marvell's Position In AI Infrastructure

The shifting roadmap underscores the growing demand for alternative AI infrastructure enablers. Marvell previously gained attention as investors rotated into optical networking providers. CNBC's Jim Cramer recently highlighted Marvell's role in the sector, noting that Huang previously predicted Marvell could achieve a trillion-dollar valuation.

Technical Analysis

MRVL is in a pullback inside an uptrend posture. It is trading 9.1% below its 20-day SMA ($282.05) but still 14.6% above its 50-day SMA ($223.63). The 50-day SMA often frames the next key trend support if selling returns. Longer-term trend structure remains constructive, with the stock 59.9% above the 100-day SMA ($160.28) and 109% above the 200-day SMA ($122.63). RSI at 46.40 points to neutral momentum.
