S&P 500 Rides AI Earnings Wave as Dell Backlog Hits $95B

The S&P 500's tech-heavy complexion is getting a fresh jolt from AI infrastructure spending, with Dell's server backlog swelling to $95 billion as enterprise demand accelerates. That kind of forward order strength gives index bulls a tangible data point beyond sentiment-driven rallies.

Not every earnings beat is translating into index support, though. Palo Alto Networks posted a strong quarter but still saw shares retreat, a reminder that valuation resets can offset fundamentals even in AI-adjacent names carrying heavy weight in broad benchmarks.

With Micron also drawing upgrades on the back of chip demand, the S&P 500's near-term direction looks increasingly tied to whether AI capex commentary continues outpacing already elevated expectations.
