Tech Selloff Drags Nasdaq Into Correction as AI Infrastructure Spending Fears Mount

A sharp retreat from technology shares dragged the Nasdaq Composite into correction territory on Thursday, as mounting anxiety over the pace of artificial intelligence infrastructure spending and shifting macroeconomic expectations unwound an earlier postelection rally. According to reporting by CNBC Business (https://www.cnbc.com/investingclub/2026/11/05/how-wall-streets-postelection-rally-got-obliterated-and-whats-next.html), the tech-heavy benchmark fell approximately 4.5% during afternoon trading, pushing the index more than 10% below its record close set on Oct. 6.

The S&P 500 dropped roughly 4%, with all 11 of its industry sectors falling into the red. For both benchmarks, the session marked their steepest single-day declines since April 2025, when the federal government first introduced sweeping import tariffs.

The sudden reversal took hold as investors re-evaluated the outlook for capital-intensive AI data centers following Tuesday's Democratic sweep of Capitol Hill and key gubernatorial victories. Market participants quickly rotated out of compute-heavy infrastructure plays on concerns that political leadership changes could bring stricter regulatory scrutiny and complicate financing for power-hungry facility builds.

The downturn exposed an expanding divide between well-capitalized tech giants and specialized infrastructure providers. Specialized GPU cloud operators, known as neoclouds, took the brunt of the selling pressure. Shares of CoreWeave dropped nearly 9% on Thursday, extending a slide that has erased more than half of the company's equity value since the Nasdaq's peak one month ago.

Caution from major enterprise customers compounded those pressures. Microsoft has begun tightening oversight of data center contracts signed with neocloud providers amid reassessments of expansion commitments, according to a Bloomberg report cited by CNBC Business. Speaking at an event hosted by The Wall Street Journal, Meta Platforms President Dina Powell McCormick noted that securing and constructing new data center capacity is "going to be harder."

Market analysts pointed out that while pure-play compute vendors face acute funding hurdles, mega-cap hyperscalers operate from a position of relative strength. Because companies like Meta, Microsoft, and Alphabet already command sprawling compute networks, regulatory or financing bottlenecks that force reductions in capital expenditure could conversely protect their free cash flow.

Macroeconomic expectations shifted alongside the equity slide. Pricing for a Federal Reserve interest rate hike in December fell from nearly 83% on Wednesday to 66% on Thursday, according to the CME FedWatch tool, as safe-haven bond buying pushed the 10-year Treasury yield back below 4.9%.

Investors are now looking to Friday morning's October employment report from the Labor Department. Consensus estimates tracked by FactSet project nonfarm payroll growth of 65,000 following September's weaker-than-expected 29,000 additions, with the unemployment rate forecast to remain unchanged at 4.2%.
