Broadcom vs Marvell: One of These AI Chip Stocks Is a Clear Winner
Broadcom and Marvell both just reported blowout AI chip quarters, but the gap between them runs far deeper than raw revenue numbers. Picking the right one depends on what kind of risk you are actually willing to take.

Broadcom (NASDAQ: AVGO | AVGO Price Prediction) and Marvell Technology (NASDAQ: MRVL) just delivered back-to-back AI chip earnings that told very different stories. Broadcom posted $29.59 billion in fiscal Q3 revenue on September 2, 2026, powered by custom XPUs. Marvell reported $2.739 billion on August 27, 2026, with a Google warrant reshaping its story. Both lean on hyperscalers, yet the scale gap is enormous.
Custom Silicon Booms for Both, but Broadcom Is Playing a Bigger Game
Broadcom’s AI semiconductor line hit $16.70 billion, up 221% year-over-year, with CEO Hock Tan telling investors “Q3 demand was simply hot and we’re just getting started.” XPUs made up 73% of AI revenue, with Google’s Ironwood TPU v7 shipping in volume and OpenAI’s Jalapeno accelerator ramping. Q4 AI guidance of $21.70 billion implies 236% growth. That is a staggering setup.
Marvell’s Data Center segment reached $2.17 billion, up 46% year-over-year and now 79% of total revenue. Matt Murphy said “AI-related bookings remain exceptionally robust.” An expanded Google agreement, tied to a warrant for up to 7% of Marvell’s shares, cements a multi-year custom silicon relationship spanning inference accelerators, storage controllers, and memory interfaces.
Scale Fortress vs. Pure-Play Accelerator
| Lens | Broadcom | Marvell |
| Market cap | ~$1.70T | ~$196B |
| FY guide reach | $115B AI revenue FY27 | ~$12B FY27 total |
| Free cash flow | $13.66B (46% of revenue) | $605.5M operating |
| Core edge | XPUs plus VMware software | Optical DSPs, 1.6T scale-out, custom |
Broadcom’s VMware business added $8.8 billion at a 94% gross margin, a moat Marvell simply does not have. Yet Marvell owns leadership in 800G and 1.6T optical interconnects, and its scale-up optics opportunity keeps expanding.
Next Catalysts Sit Weeks Apart
I will be watching Marvell’s October 6, 2026 Investor Day, where management is expected to quantify custom revenue through fiscal 2029 and reset the $10 billion-plus long-term target. For Broadcom, the December quarter report and any update on the $230 billion fiscal 2028 AI framework will matter more. Supply of substrates, HBM, and data-center shells could throttle either name.
Why I Lean Broadcom for Quality, Marvell for Torque
If you want the durable compounder, I lean Broadcom. Its 15th consecutive dividend raise, elite cash generation, and locked-in TPU pipeline with Google, Meta, OpenAI, and Anthropic suggest a lower-risk AI exposure profile. But Marvell’s 163.44% year-to-date move already reflects real momentum, and the Google warrant changes the ceiling. Marvell offers sharper upside variance for those tracking it. Conviction on either would weaken if hyperscaler capex signals crack. Right now, neither picture does.
