AMD crossed the $1 trillion market-capitalization threshold this week after a near-200% year-to-date rally that made it the ninth-best performer in the S&P 500, but the valuation math suggests the market may have gotten ahead of the fundamentals.
The numbers behind the milestone
The stock rose 2.95% on the day the milestone was reached, outpacing the S&P 500's 0.73% gain and Nvidia's 1.34% advance. Companywide revenue climbed 50% year over year to $11.5 billion in the second quarter, driven by a 107% surge in data-center sales to $6.7 billion. The source notes that AMD has released several new GPUs and improved its programming software to challenge Nvidia's CUDA ecosystem, though it does not quantify any resulting market-share shift.
Nvidia still towers in the data center
Nvidia's data-center division generated $89 billion in the same quarter, up 117% year over year, more than 13 times AMD's equivalent revenue. Nvidia's total revenue rose 106% to $96.2 billion, aided by lighter exposure to consumer and original-equipment-manufacturer demand. At $5.5 trillion, Nvidia's market capitalization remains more than five times AMD's, and its data-center business is growing at a faster pace from a vastly larger base.
The valuation disconnect
The source argues that AMD's share-price appreciation owes more to multiple expansion than to operating performance. AMD trades at 158 times trailing earnings and 81 times 2026 estimates; even on 2027 projections the multiple sits near 40 times. Nvidia, by contrast, trades below 30 times trailing earnings and at 14.7 times forward earnings using the same 2027 denominator. If both companies were to converge around 30 times trailing earnings, the source calculates AMD would face roughly 25% downside while Nvidia could double.
What the market is pricing in
The disparity implies investors are valuing AMD as if it has already captured significant share from Nvidia, despite the source's observation that AMD "hasn't done anything to take market share from Nvidia quite yet." The next test will be whether AMD's product roadmap can translate into measurable revenue acceleration in the data center, or whether the current multiple proves to be a lead balloon.
