Intel surge lifts wider semiconductor sector

Intel Corporation shares climbed nearly 19.95% in after-hours trading to $80.10 after closing at $66.78, up 2.31% in the regular session, following stronger-than-expected first-quarter results reported on April 23, 2026.

The company posted earnings of 29 cents per share, well above the consensus estimate of 1 cent. Revenue reached $13.58 billion, topping expectations of $12.42 billion and rising from $12.67 billion a year earlier.

Investors were particularly encouraged by 22% growth in Intel's data center business, which suggested that AI-driven demand for hardware is translating into a recovery for central processing units and advanced packaging services.

Market commentators highlighted the results as evidence of a sharp turnaround at Intel and as part of a broader upswing tied to accelerating demand for AI infrastructure.

The strong Intel report reinforced a growing market view that the current phase of semiconductor demand is being driven by artificial intelligence infrastructure buildouts.

Deepwater Asset Management’s managing partner said Intel’s results “go beyond Intel and remind us how early we are in the AI buildout,” framing the move as part of a “rising tide” across the industry.

Adding to the positive tone, research firm Omdia significantly raised its semiconductor revenue forecast for 2026, citing a surge in expected demand for memory and data storage components driven by artificial intelligence.

Together, Intel’s earnings surprise and Omdia’s upgraded outlook helped shift sentiment toward a broader silicon ecosystem, rather than focusing only on specialized graphics chips.

Following Intel’s report and the improved industry forecasts, a number of semiconductor companies traded higher in the April 25 afternoon session.

The rally spread across the sector, lifting peers such as AMD, Qualcomm (QCOM) and ARM by over 10%, as investors embraced the idea that the “AI trade” was broadening beyond a single category of chips.

Semiconductor manufacturing and equipment names also advanced. Applied Materials (AMAT) jumped 3.7%, Photronics rose 4.4%, Teradyne gained 5%, Kulicke and Soffa added 4.9%, and KLA Corporation climbed 6.4%.

Analog semiconductor producer Power Integrations was among the beneficiaries as well, with its shares up 3.3% in the same session.

Several of the advancing names have experienced pronounced share-price swings over the past year, underscoring elevated volatility in the group.

Teradyne’s shares have recorded 33 moves greater than 5% over the last year, while Photronics has seen 36 such moves. KLA has logged 18 moves greater than 5% over the same period.

Recent moves for some of these stocks have been shaped by geopolitical and regulatory developments, including a US-Iran ceasefire that eased concerns over disruptions to technology supply chains and shipping through the Strait of Hormuz.

KLA and other wafer-fab equipment makers have also been affected by updated US export controls that could limit sales of certain advanced tools and services to specific customers in China without a license, reviving concerns about future demand and profitability.

Commentary around Intel’s surge emphasized that the company’s shares are reaching record levels before its foundry operations become a meaningful contributor, highlighting expectations for further growth tied to AI.

At the same time, some investors have adjusted positions, with Deepwater Asset Management’s managing partner noting that his firm had exited Intel even as he characterized the latest results as evidence of a broader industry upswing.

Across the sector, the combination of easing geopolitical risks, supportive macro conditions for capital expenditure, and rising AI-related demand has drawn strong buy-side interest in both logic and memory markets.

Market observers noted that short-term pullbacks in semiconductor names can create opportunities in what remains a volatile but increasingly AI-focused industry landscape.
