AMD's Capex Conundrum: When a Blowout Quarter Becomes a Harder Sell
Published on 08/06/2026 at 20:30 | Redaktion boerse-global.de
The arithmetic of AMD's latest earnings report is straightforward enough: revenue up 50 percent, data center sales more than doubled, and guidance comfortably ahead of Street expectations. The market's response, however, told a different story — one shaped less by what AMD delivered and more by what it now costs to keep the machine running.
Shares slid roughly 9 percent in after-hours trading between Tuesday and Thursday, a pullback that erased the glow from what was, on paper, a standout quarter. The culprit: capital expenditures of $808 million, nearly triple the $299 million analysts had modeled. A separate headline — Elon Musk's declaration that SpaceX would build its future AI infrastructure exclusively on Nvidia's "Vera Rubin" architecture rather than AMD chips — knocked another 6 percent off the stock in a single session. Friday brought some relief, with the shares recovering 2.36 percent, though the stock still sits 16.18 percent below its 52-week high.
The Numbers Were Never the Problem
For the second quarter of 2026, AMD posted revenue of $11.54 billion, up 50 percent year over year and ahead of the $11.31 billion consensus. Adjusted earnings per share came in at $1.66, topping the $1.62 analysts expected. The data center segment — powered by Instinct AI accelerators and EPYC processors — grew 107 percent to $6.7 billion, now representing 58 percent of total revenue. Third-quarter guidance of roughly $13 billion also exceeded the $12.53 billion previously anticipated.
The tension, then, is not whether AMD is growing. It clearly is. The question is whether the surge in capital spending represents a transitional investment phase — one that secures future capacity for Instinct accelerators — or a structural margin risk that will weigh on profitability before the AI business reaches full scale. How that question gets answered will determine whether the recent dip is a buying opportunity or the opening act of a longer consolidation.
Should investors sell immediately? Or is it worth buying AMD?
A Partnership Pipeline, and a Caveat
The bull case rests heavily on a flurry of recent deals. Microsoft announced on July 20 that it would deploy AMD Instinct and EPYC processors more broadly across Azure. Anthropic followed on July 22 with an agreement to use up to 2 gigawatts of Instinct MI450 GPUs for AI training and inference. A day later, AMD partnered with Cerebras on a low-latency inference solution. And on Monday, Core Scientific signed on for up to 2.5 gigawatts of data center capacity.
Wells Fargo responded to the quarter by raising its price target from $615 to $700, maintaining an Overweight rating and citing the long-term earnings potential of the AI business. Several other firms lifted targets into a range of roughly $500 to $685. Institutional investors, including Sapient Capital, added to their positions during the reporting period.
Yet even the partnership story carries a wrinkle. Anthropic, AMD's marquee customer, confirmed it is building an in-house team for custom AI chips — a move that could reduce its long-term reliance on external GPU vendors. It is not an immediate threat, but it is a reminder that the growth narrative may not run in a straight line forever.
The Bearish Counterweight
Mizuho's post-earnings note captured the skepticism. The firm raised its target from $615 to $625 and kept an Outperform rating, but explicitly warned about the implications of the capex spike for coming quarters. Nearly tripled investment versus model assumptions is not a rounding error; it could pressure margins just as competition for AI compute capacity intensifies.
Musk's pivot to Nvidia at SpaceX adds another layer — evidence that even close partners can defect when a rival's roadmap looks more compelling. Short interest in the stock hit a two-week high after the decline, suggesting a meaningful cohort is betting on further weakness. JPMorgan, meanwhile, kept its Neutral rating while lifting its target from $385 to $550, interpreting the conservative third-quarter guidance as a possible sign of internal uncertainty.

A Market Catching Its Breath
The stock's trajectory over the past year explains some of the post-earnings reaction. AMD shares have climbed 131.74 percent since the start of the year and 204.74 percent over twelve months. At that valuation, the bar for what constitutes good news is exceptionally high — and the recent pullback looks less like a rejection of the company's story than a market recalibrating expectations after a massive run.
The current price of 426.45 euros, up 1.78 percent on the day following a 419.00 euro close, remains far above the 52-week low. The rebound since the initial shock has been tangible, but the stock still trails its high by 16.66 percent in euro terms.
The next test comes on August 11, when AMD is scheduled to offer further insights at a corporate event. Until then, the capex question serves as the compass for investors navigating a stock that has delivered everything the market asked for — and been punished for what it now costs to deliver it.
