Data centre demand is outstripping supply, margins are expanding, and Wall Street's models may still be too conservative
The numbers Advanced Micro Devices Inc (NASDAQ:AMD, XETRA:AMD) posted on Tuesday were impressive - so much so, the shares shot up 17%. But the more revealing detail was buried in the guidance and the commentary around it: customer forecasts are exceeding AMD's own expectations, and supply, not demand, remains the binding constraint. That is a very different problem to have than the one many investors feared six months ago.
Demand picture has changed shape
For most of 2024 and into early 2025, the concern hanging over the AI chip sector was concentration risk. A handful of hyperscalers were driving the bulk of spending, and any softening in their capital expenditure plans threatened to ripple directly into chip revenues. That fear has not entirely disappeared, but it looks increasingly misplaced.
What AMD's results suggest is that AI infrastructure spending is broadening. The company's MI450 Series and its Helios platform are winning deployments across a growing pipeline of large-scale customers, and those customers are now locking in forecasts that stretch AMD's own visibility further forward than it has had before. That is the behaviour of buyers who are committed, not experimenting.
The use cases driving that commitment have also shifted. Inferencing and agentic AI workloads, where AMD's high-performance CPUs and accelerators are particularly competitive, are growing faster than the training workloads that dominated the earlier phase of the cycle. Inference is less about raw GPU firepower and more about efficient, scalable compute at volume. AMD is well placed there.
Margins blow for the bears
One of the more persistent doubts about AMD's AI ambitions has been whether the company could compete on performance without sacrificing profitability. The first-quarter gross margin of 55.4% puts that concern to rest, for now at least. It came in above both the company's own guidance and the Street estimate of 55.1%. Second-quarter guidance of around 56% suggests the trajectory is continuing upward.
That matters because it signals AMD is not buying market share. It is winning business at prices that sustain and improve its margin profile. As GPU gross margins continue to improve, the data centre segment is becoming a genuine earnings engine rather than a revenue line propped up by aggressive pricing.
A $700 billion capex question
Wedbush analyst Dan Ives has been among the more vocal bulls on AI infrastructure, and his team's note following the results framed the moment in characteristically direct terms: hyperscalers are on course to invest more than $700 billion in capital expenditure in 2026. Microsoft, Meta, Alphabet and Amazon are all running expansion programmes of a scale that has few historical precedents outside wartime industrial mobilisation.
The critical point Ives makes is that enterprise and government adoption of AI is still at an early stage. The hyperscaler spending is laying the pipes. The application layer, where businesses deploy AI at the department and process level, is only beginning to draw on that infrastructure. When it does, the demand signal feeding back into hardware will intensify further.
What the pre-market move means
The after-hours reaction to AMD's results was positive, and pre-market trading on Wednesday suggests that the move is holding and extending. That is worth noting because after-hours moves on earnings can be volatile and short-lived, particularly when results are already well-flagged. Sustained pre-market strength usually reflects institutional buyers who need time to review results before acting, and who are comfortable adding exposure at current levels.
The risk to that picture is macro rather than fundamental. Any deterioration in the trade environment or a shift in hyperscaler sentiment around capital expenditure timing would register quickly in AMD's share price. But based on what the company reported on Tuesday, the underlying demand story remains intact and, by most measures, is still accelerating.
