Global stocks fall on AI worries as US midterm voting gets underway

what happened

Global equities came under pressure on Tuesday as a renewed wave of worry about artificial intelligence weighed on sentiment, and investors stayed nervous while polling opened in the US midterm elections, Reuters reported. Traders on Polymarket put the chance of Democrats winning both chambers of Congress at roughly 77%. Analysts say such an outcome could bring tougher oversight of AI and stricter rules for companies.

Tech earnings have disappointed. Apple warned that gross margins in the key holiday quarter will shrink because memory chips are getting more expensive, and its services revenue outlook fell well short of forecasts. S&P 500 futures slipped 0.14%, the pan-European STOXX 600 lost 0.6%, South Korea's KOSPI dropped 3.6%, and Taiwan's index fell by the same amount. Brent climbed 1.6% to $106.44 a barrel as signals from Washington and Tehran about ending the Middle East war kept flip-flopping. The dollar index eased to 101.69, while the 10-year Treasury yield rose to 4.9064%. Bitcoin dipped 0.1% to $76,638.66 after last week's Binance hack.

why it matters

Investors are weighing several risks at once. Standard Chartered analysts note that a Republican sweep would likely push Treasury yields and the dollar higher. Uncertainty over a possible US-Iran deal keeps oil swinging, while a People's Bank of China plan to raise FX reserve requirements weighed on the yuan after a long rally. Each factor could move markets on its own, and together they keep traders cautious.
