Wall Street's AI Reckoning: Stocks Slide Again as the $700 Billion Question Gets Louder

The AI trade that powered Wall Street to record after record is suddenly getting a reality check. Stocks slid for a second straight session, with the S&P 500 falling 1.44% to 7,365 and the Nasdaq Composite tumbling 2.21%. The selling wasn't broad-based panic — it was laser-focused on the one theme that has defined this entire bull market: artificial intelligence.

The Number That Spooked Everyone

The big tech "hyperscalers" — Amazon, Microsoft, Alphabet, and Meta — are collectively planning to spend somewhere between $600 billion and $700 billion on AI infrastructure in 2026. That's a staggering 36% to 71% jump from last year. For two years, investors cheered every dollar of that spending. Now they're asking a more uncomfortable question: where are the returns?

From "Buy Everything" to "Show Me the Money"

The mood shift is subtle but important. The market isn't saying AI is a bust. It's saying the easy money phase — where you bought anything with "AI" attached and watched it soar — may be over. Investors are starting to demand proof that all this capital expenditure translates into actual profits, not just bigger data centers and louder press releases.

Chips Took the Brunt

Semiconductor stocks led the slide, which makes sense — they've been the purest way to bet on the AI build-out. Memory and chip names sold off hard, dragged lower in part by steep losses in South Korean semiconductor stocks overnight. When the market gets nervous about AI spending, it sells the picks-and-shovels companies first.

Is This a Crack or a Correction?

History offers some comfort. Earlier this month, a similar AI-driven selloff wiped out more than a trillion dollars in chip value — and the market clawed much of it back within days. Most analysts still frame these episodes as valuation resets rather than the end of the AI story. The fundamentals, they argue, remain intact: data center demand is real and the build-out is continuing.

What to Watch Now

The next catalyst is enormous: Micron reports earnings after the close today, giving investors their first hard data on whether AI demand is still red-hot or starting to cool. Combine that with a hawkish Fed and Thursday's inflation report, and you have a market walking a tightrope. The AI bull market isn't necessarily over — but the days of not asking hard questions clearly are.
