Thesis. AI revenue tripled to $16.7B with a roadmap to $115B in FY27 and $230B in FY28 across six custom-silicon customers. But Broadcom is now guaranteeing financing for two of them, and the stock sits 26% off its high on exactly that concern.
Reviewed 11 September 2026, after Q3 FY2026 results. Next review after Q4 earnings on 10 December 2026.
What it does
Three businesses under one roof, and the combination is the point.
Custom AI accelerators (XPUs). Broadcom co-designs the bespoke AI chips hyperscalers build instead of buying NVIDIA GPUs — Google's TPU, Meta's MTIA, OpenAI's Jalapeño, and Anthropic's silicon.
AI networking. The Tomahawk and Jericho switch chips that connect those accelerators to each other. Broadcom sells the pipes as well as the chips.
Infrastructure software. VMware, CA and Symantec — a $69B acquisition that produces sticky, extremely high-margin cash. CEO is Hock Tan.
An XPU is a custom accelerator built for one company's workload. It trades NVIDIA's flexibility for better cost per unit of work — and it's why Broadcom wins whether or not hyperscalers keep buying GPUs.
Bull case
- Q3 FY2026, reported 2 September: revenue $29.6B, up 86%, with record operating margin of 67.9% and non-GAAP gross margin around 75%
- AI semiconductor revenue $16.7B, up 221% year over year and 54% sequentially — beating Broadcom's own $16B target by $700M. Adjusted EPS $3.32
- The roadmap doubles twice. FY26 AI revenue raised to $58B, FY27 targeted at $115B, FY28 at $230B. That path implies over $30 of EPS in FY2028 against consensus near $25.86
- Six XPU customers, four of them named — Google with TPU v8i ramping to high volume, Anthropic, OpenAI with Jalapeño shipping, and Meta with MTIA in production for inference and recommendation
- Q4 guides AI to $21.7B, up 236%, with both XPUs and AI networking expected to triple year over year
- Software is a cash machine. $8.8B, up 29%, at an 84% operating margin
- Contracted work is enormous. Remaining performance obligations of $164.6B
- It returns capital, paying out 50% of prior-year free cash flow as dividends — rare for an AI name
Bear case
- Broadcom is financing its own customers. It may provide residual value guarantees on financing for two pre-profit AI labs, so part of its future revenue is underwritten by its own balance sheet. Vendor financing at cycle highs is a well-worn pattern
- Customer concentration is severe. Six XPU customers, and one programme delay is material to a quarter
- The rest of the business isn't growing. Non-AI semiconductors grew 5%, with wireless declining
- Custom silicon is contestable. Marvell competes for the same programmes, and any customer can move a design in-house
- Q4 revenue guidance of $34.8B came in below the $35.03B consensus, even as AI guidance beat
- The market has stopped rewarding beats. The stock is roughly 26% below its June high of $495 and up only about 6% year to date, trailing the semiconductor index badly
- Policy exposure — around 17% of FY25 revenue shipped to China and Hong Kong
- VMware price rises risk churn, and the acquisition debt is still being paid down
Major customers
Custom AI accelerators — six core customers, four publicly identified
- Google — TPU, the longest-running and largest programme
- Meta — MTIA, now in production shipments
- OpenAI — Jalapeño, shipping
- Anthropic
- Plus two unnamed
Networking silicon — Arista is a major buyer of Tomahawk and Jericho switch chips, as are Cisco, Juniper and the white-box ODMs including Celestica.
Non-AI semiconductors — Apple has historically been the largest single customer at around 20% of revenue for iPhone RF filters, though that figure needs verification against the current filing. Plus broadband and set-top operators and storage OEMs.
Infrastructure software — VMware, CA and Symantec sell to thousands of enterprise and government accounts, with minimal concentration.
Read-through — Broadcom touches this file from several directions at once.
It supplies ANET with switch silicon, so Broadcom's networking commentary leads Arista's revenue. It partners with CLS on the OpenAI accelerator programme. It competes with MRVL for custom silicon designs.
And it is now expanding into LITE and COHR's territory — investing in EMLs and CW lasers to meet its own demand. Broadcom is already a top-three EML supplier. Read that first as confirmation the laser shortage is real, and second as a competitive threat.
GOOG TPU volumes are a direct driver. Any shift of TPU design in-house, or share loss to another partner, hits Broadcom immediately.
What would change the view
- The residual value guarantees — size, disclosure, and whether the two AI labs reach profitability
- AI-semi revenue against the $115B FY27 path — the first checkpoint on a very ambitious plan
- New custom-silicon wins, and whether the two unnamed customers get disclosed
- Networking share as Tomahawk 6 and 7 ramp
- VMware retention through the price increases
- Non-AI semiconductors — whether the 5% growth ever recovers
- Hyperscaler capex generally, since six customers carry the story
Update log
- 11 Sep 2026 — Reviewed. Verdict held at Conviction on the business, with the multiple already compressed to around 12x the FY28 EPS target.
- 2 Sep 2026 — Q3 FY2026 results: revenue $29.6B (+86%), AI semiconductor revenue $16.7B (+221%), record 67.9% operating margin. FY27 and FY28 AI targets of $115B and $230B introduced. Customer financing flagged as the material new risk — residual value guarantees for two pre-profit AI labs. Broadcom's move into EML and CW lasers added as a new competitive vector against Lumentum and Coherent.
