Intel delivered its strongest quarterly revenue growth in more than fifteen years on Thursday, and the market’s response to that number says as much about where investor expectations had drifted as it does about the underlying business. The chipmaker reported second quarter 2026 revenue of $16.13 billion, up 25.4 per cent year over year and well ahead of the $14.42 billion analysts had modelled. Non-GAAP earnings per share came in at $0.42, more than double the $0.21 consensus estimate, and the beat extended across nearly every line item management had guided to.

The headline GAAP figure told a different story. Intel posted a net loss of $2.16 per share on a GAAP basis, driven by a $12.53 billion non-cash charge tied to its CHIPS Act escrow arrangement, the kind of accounting treatment that can make a genuinely strong quarter look weak to anyone reading only the top line. Strip that out, and the picture is considerably brighter. Data centre revenue, the segment most directly tied to the artificial intelligence build-out, rose 59 per cent to $6.3 billion, while the client computing group that still anchors most of Intel’s revenue base grew 13 per cent to $8.9 billion.

Management’s guidance for the third quarter called for revenue of $15.8 billion to $16.8 billion and non-GAAP earnings per share of $0.38, alongside a decision to lift full-year capital spending to more than $20 billion, roughly $3 billion above the earlier plan. Most of that increase is earmarked for tooling behind the 18A and 18A-P manufacturing nodes, the processes central to chief executive Lip-Bu Tan’s effort to turn Intel into a credible external foundry, not just a chip designer running its own fabs.

What makes this report worth watching closely is the disconnect between the size of the beat and the market’s reaction to it. Intel shares had already climbed roughly 170 per cent for the year heading into the print, and more than 300 per cent over the trailing twelve months, largely on the expectation that a turnaround of exactly this shape was coming. Shares initially jumped as much as 12 to 13 per cent in after-hours trading once the numbers crossed the wire, then gave back more than half of that move within hours as investors who had already priced in the recovery took the opportunity to book gains. That pattern, a large beat met with a fading rally, is a reminder that valuation matters even when the fundamentals are moving in the right direction.

For readers watching Intel as a proxy for the broader AI infrastructure trade, the more durable signal here is not the one-day price action but the trajectory underneath it. A foundry business reporting 85 per cent yields, an expanded relationship with Google Cloud, and a manufacturing deal tied to the 18A node with a major cloud provider all point to a company whose turnaround has moved from aspiration to execution. Whether the stock has room to run from here depends less on Intel’s ability to keep beating estimates, which it has now done for seven consecutive quarters, and more on whether the market is willing to keep paying up for a story that has largely already played out in the share price.
