Custom silicon and mission-critical software are brutally hard to replace.

✦ The bottom line
Broadcom's moat is entrenchment. Its custom chips are co-designed into a customer's product over years; its software (VMware) runs the world's data centers. Both let it keep 68¢ of every dollar.

Cents kept per dollar of sales
Of every $1 of revenue, the cents kept before overhead. When customers can't easily switch — because your chip is baked into their product, or your software runs their whole operation — they pay up, and the margin shows it.
Wall Street calls this
Gross margin
A *68¢* gross margin across both chips and software is the entrenchment, measured in money.
The moat, measured · gross margin
~68
¢
Of every dollar Broadcom sells, it keeps about 68¢ before overhead — proof customers can't easily walk away.
That margin isn't from one clever chip — it's from a strategy: buy entrenched franchises, then run them for cash. Broadcom is less an invention machine than an acquisition machine, assembling businesses that customers can't live without. Here's how today's Broadcom got built.
How the empire was assembled
2009
Avago (chip maker from HP's roots) goes public.
2016
Buys Broadcom and takes its name — a chip powerhouse forms.
2018-19
Buys software firms CA and Symantec — adds sticky enterprise software.
2023-now
Buys VMware for ~$69B; pivots chips hard into *custom AI silicon*.
The moat, in the AI numbers
Broadcom achieved record first quarter revenue on continued strength in AI semiconductor solutions. Q1 AI revenue of $8.4 billion grew 106% year-over-year … driven by robust demand for custom AI accelerators and AI networking.
↳ 'Custom' is the moat word: these chips are co-designed for one customer over years, so they can't be swapped for an off-the-shelf rival. That lock-in is why margins hold.
