AI Spending Debt Fears Trigger Nasdaq Selloff as Investors Reassess Returns

What’s happening

The Nasdaq fell more than 2% Thursday—its worst day since June—as investors reassessed the massive debt loads AI companies are carrying to finance data center and chip infrastructure. Meta and Tesla led declines as concerns mount that AI capex spending is outpacing revenue generation and ROI timelines are extending.

Market impact

Mega-cap AI beneficiaries (Nvidia, Meta, Tesla) are under pressure as the market reprices AI valuations downward. Treasury yields compressed as flight-to-quality accelerated, with the 10-year dipping below 5%. Credit spreads are widening, particularly for high-leverage AI infrastructure plays like CoreWeave, which saw shares drop 29% in October.

Broader implications

The AI spending correction is forcing a reckoning on whether autonomous agents and frontier models justify the capex intensity required to train them. If debt servicing costs rise faster than AI revenue streams materialize, expect a wave of refinancing pressure and potential defaults among overleveraged infrastructure providers.
