Marvell Technology (MRVL) fell 7% then 20% on fears of losing Amazon and Microsoft to Broadcom or Alchip. Q4 data-center revenue hit $1.5B with 40% growth projected for fiscal 2027.
Marvell’s Q4 earnings showed strong 1.6T bookings and expanding design wins, proving hyperscalers are deepening commitments rather than defecting.

Two months ago, Wall Street analysts triggered a sharp sell-off in Marvell Technology (NASDAQ:MRVL) shares. Fears that the company could lose major hyperscaler customers such as Amazon (NASDAQ:AMZN) and Microsoft (NASDAQ:MSFT) to rivals sent the stock tumbling 7% in a single session. Over the ensuing weeks, MRVL shed roughly 20% of its value as concerns mounted.
With a fairly narrow customer base heavily weighted toward a handful of Tier 1 hyperscalers, the loss of even one major account could prove devastating to growth projections in the high-margin data-center segment. Yet, after Marvell’s fourth quarter earnings report, it seems all those worries were for nothing.
Marvell’s management delivered a clear message of confidence during the March 5 earnings call. “We are also seeing very strong bookings from multiple Tier 1 customers for our 1.6T solutions, which entered production in Q4 2026,” CEO Matthew Murphy stated. “Reflecting this demand and our first-to-market technology leadership, we expect our 1.6T revenue to ramp very rapidly in fiscal 2027, with substantial additional growth projected in fiscal 2028.”

The 1.6T products — high-speed optical and electrical interconnects critical for scaling AI training clusters — represent the next leap in data-center bandwidth. Marvell was the first to market 200 gigabytes per second (Gbps) per lane technology, enabling the transition to 1.6 terabits per second. Early shipments of 1.6T Coherent Light modules and the announcement of secure 1.6T ZR/ZR+ DCI modules powered by a new 2nm DSP underscore its technological edge. Bookings for these solutions are accelerating at a record pace across the entire data-center portfolio, with interconnect revenue now expected to grow more than 50% year-over-year in fiscal 2027.
Far from distancing themselves, Marvell’s hyperscaler partners are leaning in deeper. The company is engaged in “joint product roadmap discussions in full swing” with customers, giving it privileged insight into their evolving needs. Management highlighted more than 20 design wins or product sockets across the top four U.S. hyperscalers that are scheduled to enter production by fiscal 2028-2029. Diversification within each account is already substantial, spanning interconnect, switching, storage, and custom silicon.
In fact, Marvell expects to supply DCI modules to all five major U.S. hyperscalers in fiscal 2027. This breadth — combined with new wins in AEC/retimers and partnerships such as Celestial AI for photonic fabric — demonstrates that customers are not shopping for alternatives; they are expanding their reliance on Marvell’s ecosystem. CFO Chris Koopmans confirmed the supply chain is fully secured to support this multi-year ramp, removing any execution risk that could have fueled earlier skepticism.
The numbers tell the story of deepening entrenchment rather than defection. Data-center revenue reached $1.5 billion in Q4 alone and is projected to grow 40% year-over-year in fiscal 2027, while approaching 50% growth in fiscal 2028. The revenue mix is shifting decisively toward higher-value interconnect and custom solutions. Custom revenue, which scaled from zero to $1.5 billion in fiscal 2026, is now expected to grow more than 20% in fiscal 2027 and at least double in 2028, driven by lead XPU programs, follow-on XPUs, and accelerating CXL/NIC attach opportunities.
Interconnect, switching, and custom products together are propelling the segment toward an exit run-rate above $3 billion by the end of fiscal 2027. Rapid customer adoption and program scale-up are the clear drivers. Rather than contemplating exit strategies, hyperscalers are placing larger, longer-term bets on Marvell’s platforms. The earlier analyst narrative — that Amazon might hand Trainium designs to Alchip or Microsoft might pivot Maia-2 work to Broadcom (NASDAQ:AVGO) — has been overtaken by tangible evidence of multi-generational commitments.
Customer defections are always a possibility in the hyper-competitive semiconductor industry and cannot be dismissed outright. Hyperscalers themselves remain acutely concerned about single-supplier reliance, especially after recent industry-wide chip shortages. Prudent diversification across vendors is a logical risk-mitigation step.
Yet the evidence from Marvell’s Q4 report and forward guidance points to the opposite outcome: these customers are not leaving — they are doubling down. With first-to-market 1.6T leadership, diversified sockets inside each hyperscaler, and a clear line of sight to explosive growth in custom and interconnect revenue, Marvell appears firmly positioned to retain and expand its AI empire. Wall Street’s earlier panic looks increasingly overblown.
Wall Street is pouring billions into AI, but most investors are buying the wrong stocks. The analyst who first identified NVIDIA as a buy back in 2010 — before its 28,000% run — has just pinpointed 10 new AI companies he believes could deliver outsized returns from here. One dominates a $100 billion equipment market. Another is solving the single biggest bottleneck holding back AI data centers. A third is a pure-play on an optical networking market set to quadruple.
