Alphabet, the parent company of Google, reported revenues of $119.8 billion for the second quarter of 2026 — up 24% from the same period a year earlier. That is strong growth. But the company's stock price fell 6.9% after it raised its spending forecast for the year. Alphabet now expects to spend between $195 billion and $205 billion in 2026 on big infrastructure projects, up $15 billion from its previous estimate of $180 billion to $190 billion (Alphabet Q2 2026 Earnings Release; S&P Global Market Intelligence). The company said the money is going toward building AI infrastructure.

Here is why that matters. Free cash flow is the money a company has left over after paying all its bills and investing in its business. Think of it like your take-home pay after rent, groceries, and putting money into a savings account. In Q2 2026, Alphabet's free cash flow was negative $5.9 billion — meaning it spent more than it took in. That is a sharp reversal from the first quarter, when it had a positive $10.1 billion in free cash flow (Reuters; Alphabet Q1 2026 Earnings Call). Over the past 12 months, Alphabet's free cash flow totaled $53.3 billion, down from $64.4 billion at the end of Q1 (Alphabet Q2 2026 Earnings Call; Alphabet Q1 2026 Earnings Call). The company still has $242.5 billion in cash and investments on hand, which is a very large cushion, but the trend is going in the wrong direction.

Tesla had a similar problem. In Q2 2026, Tesla's operating cash flow was $4.7 billion, but after subtracting its capital spending, free cash flow was negative $1.1 billion. That was actually better than what analysts expected (they predicted a loss of about $3.3 billion), but it was still a drop from Q1, when Tesla had positive free cash flow of $1.4 billion (WSJ; Tesla IR; Tesla Q1 2026 Update). Tesla's cash holdings fell by $1.2 billion during the quarter, and its profit dropped 5% compared to a year earlier (Tesla Q2 2026 Update; WSJ). Analysts had expected operating cash flow of about $3.4 billion and capital spending of about $6.7 billion (Tesla IR). Tesla's stock dropped nearly 10% during a broader sell-off in technology stocks (MarketWatch).

The sell-off was made worse by rising oil prices, which hit $100 a barrel during the same period and pushed stock prices down across the board (MarketWatch). On April 29, 2026, Alphabet announced it would pay a small cash dividend of $0.22 per share to shareholders — a modest payout that now sits alongside a quarter where the company spent more cash than it generated (Alphabet Investor FAQs).

The bigger picture is that the largest technology companies are spending enormous sums on AI, and that spending is growing fast. Collectively, the biggest AI companies could spend more than $770 billion in 2026 on infrastructure — about 23% more than previously expected (CNBC). Wall Street estimates about $300 billion in bonds (essentially IOUs that companies sell to investors to raise money) will be issued this year to fund these AI projects (Advisor Perspectives). AI spending among major tech companies in 2026 is nearly six times what it was in 2022 (Neuberger Berman).

This spending is already affecting the financial health of these companies. Free cash flow across major technology firms has dropped noticeably because of AI spending, and analysts expect that continued investment in AI will push large tech companies into negative free cash flow territory — meaning they will spend more than they earn from operations (Neuberger Berman; Breckinridge). To fill that gap, companies are turning to the bond market — borrowing money to pay for infrastructure that their day-to-day business earnings can no longer cover.

The core tension is a disconnect between growing sales and shrinking cash. Alphabet's 24% revenue growth is impressive. But investors sent the stock down 6.9% because each new dollar of revenue is coming with a higher price tag in capital spending — the company has to spend more on data centers, chips, and energy to generate that growth. Alphabet's $242.5 billion in cash gives it a large safety buffer, but the direction matters: a company losing cash each quarter while raising its spending forecast by $15 billion is moving fast enough to warrant caution, especially if revenue growth slows. Tesla's situation is tighter: it has less cash on hand, its profit is shrinking, and its spending levels ($6.7 billion expected by analysts) produced negative free cash flow even though its operating cash flow beat expectations.

For people who lend money to these companies by buying their bonds, the picture is simpler. Major tech companies are increasingly borrowing to fund AI infrastructure, and the amount they plan to borrow — roughly $300 billion this year — will test whether enough investors want to buy those bonds at a time when oil at $100 a barrel and market volatility are already making financial conditions tighter.
