Advanced Micro DevicesNarrow moat

AMD designs processors and manufactures none of them. Its products are the three kinds of silicon a computer can be built from: CPUs — the x86 processors it is one of only two companies licensed to make¹ — GPUs, from Radeon graphics cards to the Instinct accelerators chasing Nvidia in AI, and the adaptive chips (FPGAs) that came with the $49 billion Xilinx acquisition. Every one of them is fabricated by TSMC. AMD's business model is to keep the expensive part of its brain — architecture, chiplets, design — and rent the expensive part of its body, which makes it a royalty-free intellectual-property company that happens to book hardware revenue.

The money map has been redrawn twice in a decade. Of fiscal 2025's $34.6 billion in revenue, up 34%², Data Center contributed $16.6 billion — EPYC server processors plus Instinct AI accelerators, nearly half the company. Client — the Ryzen chips in desktops and laptops — added $10.6 billion; Gaming, which lives mostly inside Sony and Microsoft consoles, $3.9 billion; Embedded, the old Xilinx franchise selling into industrial, aerospace and telecom sockets, $3.5 billion. Then the map moved again: in the second quarter of 2026 revenue hit a record $11.5 billion, up 50%, with Data Center at $6.7 billion — 58% of the whole company — after more than doubling year over year³.

Look closely at how the profit arrives, because it explains the strategy. Trailing-year net income is about $6.4 billion on $41 billion of revenue — a mid-teens margin against Nvidia's fifty-plus — because the challenger prices to take share and carries a heavy amortization bill from the Xilinx deal. AMD earns like an insurgent: thin today, on the theory that volume and the AI ramp fatten tomorrow.

Two numbers frame the wager the stock actually represents. EPYC has taken roughly 40% of the server-CPU market from Intel — the proven campaign. In AI accelerators AMD holds under 10% against Nvidia⁴ — the unproven one, now underwritten by OpenAI's six-gigawatt commitment and the Helios racks built to deliver it. The market has chosen its answer in advance: at roughly $1.02 trillion and about 159 times trailing earnings — the richest multiple of any chip company in this collection⁵ — the price assumes the second campaign ends like the first.

That is the frame for everything that follows: a real, narrow moat — the x86 duopoly, the chiplet playbook, the embedded annuity — priced as if the AI war were already won. The Moat pages weigh what actually protects the franchise; the Future Bets pages track the OpenAI gigawatts, the racks, the 2-nanometer first and the sovereign venture that must now justify the multiple. Each of the four segments is taken in turn in The Revenue Lines.
