Tech stocks shed $1 trillion as oil hits $110

Tech stocks suffered one of the sharpest selloffs of 2026 on Friday as oil prices surged past $110 a barrel, reviving fears about inflation, interest rates and the debt financing the artificial intelligence boom. The Nasdaq 100 dropped 2.5 percent, the S&P 500 fell 1 percent and the Russell 2000 slid 1.6 percent, while more than $1 trillion in technology market value was wiped out in a single session. Brent crude, the international benchmark, pushed past $110 shortly after 2:30 p.m. ET for the first time since May and finished the week at $109.86 a barrel, its highest closing level since May 19. U.S. crude jumped 3.5 percent to close at $101.41, the first time West Texas Intermediate crossed the $100 mark since September. The sharp drop in tech stocks came as worries about ballooning AI debt, elevated interest rates and rising energy costs all resurfaced at once. AI stocks, the market's leaders for much of the year, bore the brunt of the selling. ## Why tech stocks fell as oil surged Rising oil prices sit at the centre of the selloff. The steady climb in fuel prices began this spring, when the United States and Israel attacked Iran in late February and triggered the closure of the Strait of Hormuz. An escalation in the Russia-Ukraine war in recent months then pushed prices higher still, with diesel futures jumping more than 1 percent on Friday alone. Higher energy costs feed directly into inflation expectations, and inflation expectations feed into interest rate expectations. The Federal Reserve already raised its benchmark rate by a quarter point in September to tame inflation driven by higher oil and gas prices, and traders now see a greater chance of another increase before the end of the year. Rate-sensitive tech stocks are usually the first casualties when borrowing costs look set to stay elevated. ## AI debt weighs on tech stocks The second pressure point is the borrowing behind the AI buildout. Investors have grown uneasy about the scale of debt being taken on to fund data centres, chips and power infrastructure, and Friday's rout suggested that unease is hardening into a repricing. The Philadelphia semiconductor index dropped 3.8 percent for its eighth consecutive day of losses, the longest such streak since 2008. The Nasdaq 100, which tracks most of the country's largest technology and AI-linked companies, now sits about 7 percent below its most recent all-time high, a record it had only set the previous week. The speed of the reversal has rattled even longtime holders of tech stocks. Diesel, the commercial fuel critical for farming, trucking and other industrial sectors, has risen even faster than regular gasoline in recent months, squeezing margins across supply chains and adding to the cost pressures facing corporate America. ## What could move tech stocks next Analysts say the path forward depends on two variables: crude and credit. If crude stabilises, inflation fears could ease and give the Federal Reserve room to hold rates steady. If it keeps climbing, the odds of another rate increase rise, and high-multiple tech stocks would likely face further selling. For now, the market's message is blunt. After a year in which AI stocks carried the broader market higher, investors are demanding proof that the spending behind the boom can generate returns before borrowing costs climb further. Until that evidence arrives, volatility is likely to remain the defining feature of trading. The selloff also serves as a reminder that the AI trade is not insulated from the old economy. When energy markets seize up, the cost of capital moves, and the most richly valued tech stocks feel it first. Friday's $1 trillion wipeout showed how quickly that transmission can work.
