AMD just delivered one of its strongest quarters on record. The market’s response was to sell the stock anyway.
On August 4, AMD reported Q2 2026 revenue of $11.54 billion, clearing the analyst consensus of roughly $11.3 billion. Adjusted earnings per share came in at $1.66, above the expected $1.62. Data center revenue grew 107% year-over-year to approximately $6.72 billion.
Then the after-hours session opened, and AMD shed roughly 8% of its value. The stock had climbed 7% during the regular session, which means investors essentially bought the rumor, then aggressively sold the news.
Three numbers that spooked the market
First, capital expenditures. AMD spent $808 million in the quarter, nearly three times the analyst expectation of $298 million.
That spending surge hit free cash flow hard. AMD’s free cash flow for the quarter came in at $1.56 billion, a sequential decline and well below what analysts had modeled.
Second, the forward guidance. AMD projected Q3 2026 revenue of approximately $13 billion, plus or minus $300 million.
Third, Elon Musk announced that SpaceX would pivot to using Nvidia chips exclusively for future AI projects.
The AMD vs. Nvidia context
Nvidia’s H100 and its successors have become the default infrastructure choice for large-scale AI training workloads. AMD has made real progress with its Instinct MI-series accelerators and has been winning enterprise customers, but Musk’s SpaceX announcement is a reminder that the biggest AI spenders are often locking in with one supplier rather than diversifying.
CEO Lisa Su pushed back on the pessimism. She highlighted record results across the business and pointed to AMD’s AI roadmap, specifically calling out the upcoming Helios platform as evidence the company is investing for long-term positioning rather than short-term margin protection.
What investors are actually watching
The gap between $808 million in actual capex and $298 million in analyst expectations signals that AMD’s investment cycle is entering a heavier phase, and investors need to recalibrate their assumptions about what free cash flow looks like during that phase. If the Helios platform and future products deliver the market share gains Su is projecting, the spending will look prescient in hindsight.
The Q3 guidance range of approximately $13 billion gives AMD room to beat again, which could reset sentiment if the company executes.
