Intel (INTC) Stock Falls as UBS Warns of AI Chip Bubble

TLDR

• Intel stock dropped over 4% in premarket trading Friday, with AMD and Arm also falling as investors take profits after a huge run-up.
• UBS warns AI chip stocks risk repeating past market bubbles, calling the recent rally a near 3-standard-deviation event.
• Intel lost 370 basis points of server CPU market share in Q1, falling to 54.9%, while AMD and Arm both gained ground.
• Year-over-year, Intel shed 950 basis points of server market share — AMD and Arm each picked up hundreds of basis points.
• UBS sees a potential bright spot for Intel in its new Coral Rapids chips and PC demand from locally run AI workloads.

Intel stock fell more than 4% in premarket trading on Friday, hitting $111.27, as a wave of profit-taking hit the semiconductor sector following a historic run.

Advanced Micro Devices dropped 3.4% and Arm Holdings fell 4.4% in the same session. All three stocks have surged in recent months on expectations that AI infrastructure buildout would drive demand for their chips.

Intel has risen more than fivefold over the past 12 months, making it a standout performer — but that kind of run tends to attract scrutiny.

UBS analyst Michel Lerner, head of HOLT, issued a note warning that markets may be getting ahead of themselves. “There is a risk that markets are running too hot on the AI story,” Lerner wrote. He described April’s U.S. stock price move as a 2.8 standard deviation event over the last 25 years.

The firm noted that AI semiconductor stocks are on track for an average 30% cash flow return on investment (CFROI) this year. That sounds great — until you look at history. Only one in five companies has managed to sustain that level a decade after first achieving it.

“Markets are assuming that the lifecycle of AI firms is different to all other companies historically and that they are immune to normal competitive dynamics,” Lerner wrote.

Intel Losing Ground in Server Market

Beyond the macro warning, Intel has a company-specific problem. A new UBS report confirmed Intel is losing server CPU market share — and its rivals are the ones picking it up.

In Q1 2026, Intel held 54.9% of the server CPU market, down 370 basis points from the prior quarter. AMD climbed 230 basis points to 27.4%, while Arm gained 140 basis points to reach 17.7%.

Year-over-year, the picture is starker. Intel shed 950 basis points. AMD gained 330 basis points. Arm gained 620 basis points. That’s not a one-quarter blip — it’s a trend.

The data center AI market is growing, but Intel is capturing less of it with each passing quarter.

A Potential Upside for Intel

Not everything in the report was negative for Intel. UBS highlighted the company’s upcoming Coral Rapids chips as a potential catalyst.

The bank also noted Intel could “benefit on the PC side as locally run agentic workloads drive demand over the medium term.” In other words, as AI moves onto personal devices, Intel’s PC-oriented architecture could get a second look.

Still, the overall direction of the server market is clear. AMD and Arm have momentum, and Intel will need a strong product response to reverse the trend.

As of Friday morning, Intel was trading at $108.48, down 6.43% on the day.
