NEW YORK, July 24, 2026 – A sharp rise in crude oil prices to $100 per barrel sent shockwaves through Wall Street on Thursday, driving a broad selloff that hit both technology and airline stocks. Alphabet (NASDAQ:GOOGL) and Tesla (NASDAQ:TSLA) each fell 10.8% on an equal-weighted basis, while American Airlines Group (NASDAQ:AAL) and Southwest Airlines (NYSE:LUV) dropped 7.3%. The moves underscore how rising energy costs are rippling through markets via multiple channels, including higher bond yields and increased discount rates on future cash flows.
Oil's Dual Impact on Markets
Brent crude closed at $100.69 on Thursday, up 7% for the session and on track for a 13% weekly gain. The rally pushed the yield on the 10-year U.S. Treasury note to 4.7035%, a rise of nearly 17 basis points this week. The jump in yields reflects growing inflation expectations and a reassessment of monetary policy, with rate futures now pricing a roughly one-in-three chance of a Federal Reserve rate hike in July, up sharply from about 12% the prior week.
“Capital has a real cost again, and the room for error is shrinking every quarter,” said Thomas Monteiro, senior analyst at Investing.com. The shift in pricing has been rapid, as investors recalibrate for a higher-for-longer interest rate environment.
AI Giants Under Pressure
The technology sector bore the brunt of the selloff, with Alphabet and Tesla leading the decline. Together, the two companies consumed $7.0 billion in free cash flow during the second quarter, and their combined capital expenditure outlook for 2026 stands at a minimum of $220 billion. Alphabet’s free cash flow was negative $5.9 billion as capital expenditures nearly doubled, while Tesla reported negative free cash flow of $1.1 billion. Both companies have committed to massive spending on artificial intelligence infrastructure, but rising discount rates are making those long-term investments more expensive to finance.
Alphabet’s cloud revenue surged 82% to $24.8 billion, and overall revenue beat analyst estimates. The company raised its 2026 spending forecast to between $195 billion and $205 billion. “The demand still outpaces that investment,” said finance chief Anat Ashkenazi. Tesla reported revenue of $28.24 billion, also above expectations, but adjusted earnings of 33 cents per share missed the 51-cent consensus, as capital expenditures rose to $5.8 billion.
Airlines Feel the Fuel Pinch
Airlines, which are directly exposed to jet-fuel costs, saw their shares slide despite reporting better-than-expected quarterly profits. American Airlines and Southwest Airlines both topped estimates, but the surge in crude prices reignited concerns about fuel expenses, which are a major input cost for carriers. The declines in airline stocks mirrored those in tech, though Tesla fell nearly double the average loss among carriers, suggesting investors viewed oil as a shock to discount rates rather than just a direct cost.
Broader Market Impact
The S&P 500 dropped 1.21%, and the Nasdaq Composite shed 2.15%. Only four of the 11 S&P sectors posted gains. On the New York Stock Exchange, declining stocks outpaced advancers by nearly three to one. The S&P was heading toward a second consecutive weekly decline as of Friday, which would mark its first back-to-back weekly drop since March.
The upcoming test is the Federal Reserve’s July 29 decision, with expectations set for no change. Earnings results from Apple (NASDAQ:AAPL), Microsoft (NASDAQ:MSFT), and Amazon (NASDAQ:AMZN) are also due, drawing attention to cash flow and capital spending plans. Risks go in both directions: a ceasefire or improved shipping safety could swiftly ease oil’s war premium, while broader disturbances at Hormuz or Bab el-Mandeb could raise crude prices and yields once more.
Brent and the 10-year yield provide a clear benchmark. Declining oil paired with persistent yields highlights AI financing costs as the primary risk factor for investors.
