AMD beat on revenue, beat on profit, beat on guidance, and its shares still got taken to the woodshed. On 4 August the company posted its second quarter, and on paper it was a rout in its favour. Record revenue of 11.5 billion dollars, up roughly 50 per cent on the year. Then the market did the opposite of applause.
The engine was the data centre segment, the bit that sells server chips (EPYC processors) and AI accelerators (Instinct GPUs) to the hyperscalers building out artificial intelligence. That line more than doubled to 6.7 billion dollars, up 107 per cent, and now makes up around 58 per cent of the whole company. Non-GAAP earnings (adjusted figures that strip out one-off costs) came in at 1.66 dollars a share against expectations nearer 1.61. Guidance for the current quarter, 12.7 to 13.3 billion dollars, sailed past the 12.5 billion the street wanted.
So why did the stock close the regular session up about 7 per cent near 519 dollars, then crater almost 9 per cent after hours, and fall another 5 per cent the next day?
Priced for a blowout, and then Musk spoke
Two reasons, and neither is really about the quarter. First, expectations. When a stock trades at roughly 48 times forward earnings, a beat is the entry fee, not the prize. One analyst put it plainly: it was priced for a blowout, and merely great is a disappointment. The gross margin (the slice of revenue left after the cost of making the chips) landed near 54 per cent on a GAAP basis, softer than some hoped, because ramping the new Helios AI systems costs money up front.
Second, and more colourful, Elon Musk. On SpaceX’s own call the same day, Musk said SpaceX would build exclusively on Nvidia’s coming Vera Rubin architecture, “because we think it is the best”. Back in May he had said his companies would keep buying from both AMD and Nvidia. So on the very evening AMD showed it could double its AI business, one marquee customer publicly picked the other horse. AMD shares fell about 7 per cent on the headline.
Lisa Su, AMD’s chief executive, brushed it off, noting the company has plenty of demand from everyone else. She is not wrong. But the episode is a neat lesson in how the AI trade actually prices risk in 2026. The hardware numbers can be spectacular and the shares can still drop, because the valuation already assumed spectacular, and sentiment now turns on which billionaire says what on a Tuesday night.
For everyone who is not a trader, the useful takeaway is simpler. AMD is genuinely taking AI share, its data centre business is real and growing fast, and Nvidia still sets the mood music for the entire sector. The gap between a good business and a good stock has rarely been this wide.
Did you know: AMD’s data centre revenue of 6.7 billion dollars in this single quarter is larger than the company’s total annual revenue as recently as 2018.
