Intel shares jumped more than 11 percent after hours Thursday after the chipmaker reported its strongest revenue growth in more than fifteen years, a phrase that usually signals a turnaround but in this case mostly signals how low the bar had been set. Revenue came in at $16.1 billion for the second quarter, up 25 percent from a year earlier, while adjusted earnings of $0.42 a share came in nearly double what Wall Street had modeled.

The data center and AI group, the segment where Intel has watched Nvidia run away with the market, grew 59 percent year over year to $6.3 billion. That is the kind of number that suggests the company is finally participating in the infrastructure buildout it missed for the first half of the cycle, though it also reflects how small the base had become after years of ceding ground.

The results arrive days after Intel confirmed layoffs in that same data center unit, framed as an efficiency push. The juxtaposition is not accidental: the company is trying to convince investors it can grow the top line while cutting the cost structure underneath it, a trick that works until the cuts hit the engineering capacity needed to sustain the growth.

The foundry business, which management has bet the company's future on, remains the hole in the argument. Emarketer analyst Jacob Bourne called it a work in progress, noting it lost $2.1 billion and has yet to land the major external customers the strategy depends on. Manufacturing for others is supposed to diversify Intel away from designing its own chips and put it in direct competition with TSMC; so far it has mostly diversified the loss column.

The US government took a 9.9 percent stake last year, a fact that now looks less like a vote of confidence and more like a down payment on domestic supply chain security. Chief executive Lip-Bu Tan attributed the quarter's improvement to greater speed, accountability, and customer focus. Whether that translates into foundry customers signing contracts, rather than just evaluating them, is the only metric that will matter for the next fifteen years.
