NEW YORK, May 28, 2026, 13:02 (EDT)
Advanced Micro Devices shares jumped more than 5% in midday trading on Thursday, outpacing Nvidia and Intel as investors moved back into chip names after a brief pause in the artificial-intelligence rally. AMD traded at $520.93, up 5.1%, with an intraday high of $526.90; Nvidia rose 0.5%, while Intel slipped 0.4%. The iShares Semiconductor ETF gained 1.9%, and the Nasdaq-100 tracker QQQ rose 0.9%.
The move matters because AMD’s story has shifted from a simple Nvidia catch-up trade to a broader bet on AI infrastructure. Investors are watching whether demand for AI inference — running trained models to produce answers, not training them from scratch — can lift both AMD’s graphics processors and its central processing units, or CPUs, the general-purpose chips that run servers.
That bet got a fresh test this week. Wall Street had paused on Wednesday after the Philadelphia Semiconductor Index fell 1.4% from a record high, with Reuters reporting that chip stocks had pulled back after a strong run. Sean Clark, chief investment officer of Clark Capital Management Group, called it “a little bit of a pause,” while Adam Turnquist at LPL Financial warned that stretched momentum raised questions about the near-term durability of the advance.

AMD has had a lot to defend. Earlier this month, the company reported first-quarter revenue of $10.3 billion and said its data-center unit had become the main engine of growth. Chief Executive Lisa Su said “Data Center” was now “the primary driver” of revenue and earnings growth, and the company cited stronger demand for CPUs and accelerators used in AI systems.

The stock’s latest leg higher is also tied to capacity. AMD said on May 21 it would invest more than $10 billion across Taiwan’s chip ecosystem, including advanced packaging, the process of linking several chip components closely so they work like a bigger, faster system. The company said its Helios rack-scale AI platform, using Venice CPUs and MI450X GPUs, remained on track for deployments beginning in the second half of 2026.
Su told Reuters in Taipei last week that “the CPU market is tight” and said supply should rise every quarter this year, with more capacity planned for 2027 and beyond. She also said AMD was co-investing with Taiwan partners to secure manufacturing and packaging capacity through 2029. Reuters
The pressure is not just about getting more chips out the door. TSMC executive Kevin Zhang said on Thursday that surging electricity demand from AI had made energy efficiency the main constraint in future chip design. TSMC makes chips for AMD and Nvidia, and Zhang said customers across phones, edge devices and AI data centers were pressing for gains that do not add more power use.
That gives AMD a clearer pitch, but it does not remove the competition. Reuters reported after AMD’s May earnings that analysts and investors see the company as a leading challenger to Nvidia in AI chips, while Intel’s production push could pressure AMD in CPUs. Jake Behan, head of capital markets at Direxion, said AMD was levered to “insatiable AI compute demand,” but investors would focus on how well it turns that demand into higher-margin revenue. Reuters
Michael O’Rourke, chief market strategist at JonesTrading, put the competitive point more bluntly after AMD’s earlier rally: “Success invites competition.” Matt Britzman at Hargreaves Lansdown said AMD’s story was increasingly about a “broader compute opportunity,” with both CPUs and GPUs playing a role as AI workloads get heavier.

Macro risk is still sitting in the background. U.S. first-quarter growth was revised down to a 1.6% annualized pace on Thursday, while the personal consumption expenditures price index, a Federal Reserve-watched inflation gauge, rose 3.8% over the 12 months through April. Peter Cardillo, chief market economist at Spartan Capital Securities, said the numbers pointed to “a stagflation problem,” a mix of weaker growth and sticky inflation that can hurt richly valued growth stocks.

But the trade is not clean. If big cloud customers slow AI spending, if power and cooling costs delay data-center builds, or if Nvidia and Intel defend more of the CPU and accelerator market than investors expect, AMD’s rally could lose air quickly. The stock is being priced for supply to expand and demand to stay hot. Both have to happen.
