Intel's Q2 crushes estimates — fastest revenue growth since 2011, DC-and-AI up 59%

Intel posted Q2 revenue of $16.1B, up 25% from a year earlier — its strongest quarterly growth in more than 15 years — with adjusted EPS of 42¢ against the 21¢ analysts expected on ~$14.4B of revenue. The Data Center & AI segment led, up 59% year over year to $6.3B. Guidance for Q3 ($15.8–16.8B revenue, 38¢ adjusted EPS) landed well above the ~$15.1B and 27¢ the Street had penciled in, and shares rose after hours. The beat comes the day after Intel named Fortinet as its first external foundry customer.

Why it matters

For a turnaround stock, the two halves of the story just arrived on consecutive days — and they're not the same half. The Q2 beat is demand-side: Intel is finally catching the AI-datacenter updraft that lifted TSMC and the memory makers, translating into real revenue growth and a raised outlook. What it is not is proof of the foundry thesis — the numbers are the product business working, while the $100B+ US fab buildout still needs marquee external customers at the leading edge, which yesterday's mature-node Fortinet win only begins to address. The market gets a genuine earnings inflection; the harder foundry question is deferred, not answered.

What to watch

Whether DC&AI growth is a share gain or just riding the buildout, foundry customer announcements at the leading edge (the part the stock's long-term case rests on), and margin trajectory as the fab spend ramps.
