Broadcom AI Revenue: Nearly Half the Company, Mix Still Hidden

Broadcom collected $100 in Q2 FY2026 revenue; about $49 came from AI semiconductors. Our source-derived bridge attributes roughly $89 of every $100 in year-over-year revenue growth to AI. The engine is visible; its product mix and margins are not.

Start with the denominator: $10.8B out of $22.2B

AI demand now explains most of Broadcom's growth. The unresolved question is whether a larger engine brings clearer product mix, durable margins, and less concentration. Ignoring the $10.8B understates the engine; treating every AI dollar as equally durable overstates the evidence.

Follow the extra $7.2B of company revenue

The issuer's own statement sets the factual boundary. Broadcom reported $10.8B of AI semiconductor revenue, up 143%, driven by custom AI accelerators and AI networking. It guided Q3 FY2026 AI semiconductor revenue to $16.0B.

The segment table adds the denominator: semiconductor solutions rose 79% to $15.009B, infrastructure software rose 9% to $7.178B, and total revenue rose 48% to $22.187B.

AI was about 72.0% of semiconductor revenue. Broadcom reports profitability only for the broader segment.

The 143% growth rate implies prior-year AI revenue of about $4.444B. AI added roughly $6.356B while total company revenue added $7.183B.

The calculated non-AI bucket grew about $0.827B, or 7.8%; it is not a reported segment.

Where the proof stops

The market question is whether a fast-growing but incompletely separated AI engine deserves durable credit beside a high-margin software business. No private consensus or price target is used.

Broadcom's $10.8B AI revenue is proven; its composition is not. The matched-boundary comparison shows why unlike AI figures cannot receive equal credit. The broader AI revenue reading guide explains how to keep reported results, narrow disclosures, and management targets in separate lanes.

Fast growth can still become harder to underwrite

Concentration is the strongest counterweight: one semiconductor distributor represented 42% of revenue, up from 29%, while the top 5 end customers were about 45% of first-half revenue. Margin mix is the second: GAAP gross margin was about 69% versus 68% a year earlier, and the filing says a higher semiconductor mix offsets some software-margin benefit.

A three-number rule for the next quarter

Broadcom guided Q3 FY2026 total revenue to $29.4B and AI semiconductor revenue to $16.0B. If both land, AI would be about 54.4% of the company.

The read strengthens if AI approaches $16.0B, gross margin stays above 68%, concentration falls from 42%, and product data improve. It weakens below $14.7B of AI revenue with total revenue near $29.4B, below 68% gross margin, or at 42% concentration or higher. The next filing must improve both measurability and quality.

Calculation notes and primary sources

Company results, SEC disclosures, guidance, calculations, and editorial thresholds are kept separate. AI share is $10.8B / $22.187B; the bridge infers $10.8B / 2.43 = $4.444B, then divides the $6.356B AI increase by the $7.183B company increase.
