Big Tech Plunge Leads Wall Street Lower as AI Spending Concerns Mount

Mega-cap technology shares suffered their steepest weekly losses in months as investors questioned the commercial returns on massive, debt-financed artificial intelligence investments. The retreat dragged the Nasdaq down over 2% and spread into broader markets, while small-cap stocks remained mired in correction territory. Mounting energy costs and high borrowing benchmarks have further dampened appetite for richly valued growth assets.

U.S. Budget Deficit Hits $1.99 Trillion for Fiscal 2026

The U.S. government recorded a $1.992 trillion budget gap for fiscal 2026, marking a 12% annual increase and the third-largest shortfall in American history. Outlays were pushed higher by Social Security, Medicare, and a record net interest bill that exceeded $1 trillion on the nation's $40 trillion debt load. The ballooning fiscal imbalance has kept bond markets on edge, cementing expectations that Treasury debt issuance will remain heavy.

Warsh Remarks in Bangkok Reinforce October Fed Pause Expectations

Federal Reserve Chairman Kevin Warsh stated that the U.S. economy has broadly matched expectations, leading fed funds futures to assign an 85% probability that the central bank will hold interest rates steady this month. However, market analysts caution that Warsh's reluctance to provide explicit forward guidance leaves room for surprise policy actions if persistent inflation or elevated oil prices reaccelerate. Traders continue to price in the possibility of up to two rate hikes by the end of December.

The Market Today

U.S. equities fell sharply on Friday, led by a steep retreat in mega-cap technology and artificial intelligence names that drove the Nasdaq down 2.15% and the S&P 500 lower by 1.09%. Geopolitical tensions intensified as crude jumped on tanker attacks in the Strait of Hormuz and Ukrainian strikes on Russian refineries, lifting WTI crude to $99.00 a barrel and reigniting inflation worries. Bond yields remained sticky, with the 10-year Treasury yield edging up 1 basis point to 5.10% following news that the U.S. fiscal deficit approached $2 trillion. Energy and select financial shares resisted the broader market downturn, limiting losses in the Dow Jones Industrial Average to 0.34%.

Macro & Policy

Federal Reserve: Chairman Kevin Warsh signaled that recent macroeconomic data aligns with the FOMC's baseline, reinforcing investor bets that benchmark rates will remain steady at the late-October policy meeting. Nonetheless, futures markets continue to price in the possibility of further tightening by year-end due to stubborn services and import price inflation.
Fiscal Deficit: The U.S. fiscal 2026 deficit expanded 12% to $1.992 trillion, driven by rising non-discretionary entitlement costs and annual net interest expenses topping $1 trillion, adding to supply pressure in Treasuries.
Trade and Regulation: European Commission leadership announced plans to introduce new import curbs across additional Chinese industrial sectors, while U.K. regulators stepped up antitrust scrutiny on foreign tech and cloud ecosystems.
Geopolitics: Intensified Iranian military action against commercial vessels in the Strait of Hormuz, Houthi missile launches into Saudi Arabia, and the breakdown of a Russia-Ukraine energy infrastructure ceasefire collectively added large risk premiums back into global energy markets.
