Rising Oil Prices Drive Up Costs for Wall Street’s AI Investments

Alphabet and Tesla each declined 10.8% on Thursday on an equal-weighted basis. Shares in American Airlines Group and Southwest Airlines were down 7.3%.

NEW YORK, July 24, 2026, 04:07 EDT

Alphabet NASDAQ:GOOGL and Tesla NASDAQ:TSLA each declined 10.8% on Thursday on an equal-weighted basis. Shares in American Airlines Group NASDAQ:AAL and Southwest Airlines NYSE:LUV were down 7.3%.

The gap highlights oil’s secondary route through markets: bond yields. Airlines continue to deal with higher fuel expenses, while tech investors contend with steeper discount rates on future expenditures.

The two tech firms together used up $7.0 billion in free cash flow during the second quarter. Their outlook for 2026 signals a minimum of $220 billion in planned capital expenditures.

At 04:07 EDT, regular U.S. markets had closed, with premarket trading underway and Nasdaq futures down 0.3%.

Brent slipped 1.1% to $99.55 early on Friday but remained on track for a 13% gain over the week. The yield on the 10-year Treasury rose to 4.7035%, an increase of almost 17 basis points this week.

Rate futures assigned nearly a one-in-three chance to a July rate increase, a significant jump from approximately 12% the previous week.

The shift in pricing happened quickly. “Capital has a real cost again, and the room for error is shrinking every quarter,” said Thomas Monteiro, senior analyst at Investing.com. Reuters

The cross-asset analysis highlights areas where investors encountered pressure:

Tesla NASDAQ:TSLA−14.5%Free cash flow −$1.1 billion; capital expenditure for year exceeds $25 billion Reuters

Southwest Airlines NYSE:LUV−6.2%Jet-fuel price exposure AP News

Declines in technology stocks mirrored those in the airline sector. Tesla dropped nearly double the average loss among carriers. The trend indicates investors viewed oil as a shock to discount rates.

Cloud revenue at Alphabet climbed 82% to reach $24.8 billion. Overall revenue surpassed analyst estimates. Free cash flow stood at negative $5.9 billion as capital expenditures almost doubled.

The company increased its 2026 spending outlook, now projecting $195 billion-$205 billion. “The demand still outpaces that investment,” said finance chief Anat Ashkenazi. Reuters

Tesla reported revenue of $28.24 billion, beating expectations. Adjusted earnings came in at 33 cents, falling short of the 51-cent consensus estimate. Capital expenditures surged, rising to $5.8 billion. Free cash flow was negative at $1.1 billion.

American and Southwest surpassed estimates for quarterly profit or revenue, but their stocks declined as rising crude prices sparked renewed worries about jet-fuel expenses.

The S&P 500 dropped 1.21%, and the Nasdaq Composite shed 2.15%. Just four of the 11 S&P sectors posted gains. On the NYSE, declining stocks outpaced advancers by nearly three to one.

The S&P was heading toward a second consecutive weekly decline as of Friday. This 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.

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 provide a clear benchmark. Declining oil paired with persistent yields highlights AI financing costs as the primary risk factor.
