Marvell targeting 20% market share of $75B+ data center TAM by calendar 2028; AI revenue alone expected to 'very significantly exceed' $2.5B in FY2026, implying custom+optics >$3.5B annualized run rate
“we're definitely gaining share from 23 to 24 and we'll definitely gain more share from 24 to 25...to get to that revenue target, you got to grow the share, right, from kind of 10%, let's call it, to 20%...certainly, if the market is bigger...the world has changed since [April 2024]...We just see the TAM and the opportunity for Marvell being way larger than it was when we looked at it almost a year ago”
Why it matters
Marvell's 2028 target of 20% share in a $75B+ TAM, combined with expected multi-generational XPU and custom CPU wins, implies sustained high-capex demand at TSMC (5nm, 3nm leading-edge nodes), advanced packaging (chiplets, CoWoS, advanced interconnects), and custom HBM supply partnerships. This is a multi-year supply chain expansion, not a transient spike.
Investment implication
TSMC will face sustained advanced node capacity pressure and may require capex acceleration beyond current guidance to serve Marvell, NVIDIA, AMD, and other custom silicon customers. Advanced packaging capacity at TSMC, ASE, Amkor will be strained. HBM supply (SK Hynix, Samsung) will remain tight. Semiconductor equipment vendors (ASML, LRCX, AMAT) will benefit from elevated fab utilization and conversion to next-node production.
