Strong Earnings, Stock Price Falls: Who Is Footing the Bill for AI Infrastructure?

Author: Alea Research

Translation: TechFlow

TechFlow Editor's Note: Last week, almost all earnings reports confirmed that AI computing power demand is real, yet large-cap tech stocks fell instead. The market is repricing based on a new standard: Who will fill the funding gap for AI infrastructure—is it the company's own cash flow, customer prepayments, or debt? This determines which companies can last until the day AI monetizes.

Growing Companies Were Sold Off, Where Is the Funding Gap, and Who Pays for AI Infrastructure

Last week, most companies reporting earnings saw revenue growth, yet stock prices still fell. The S&P 500 fell 0.6%, and the Nasdaq fell 2.1%, almost every earnings report confirmed that AI computing power demand is real.

Building AI capacity means paying for chips, data centers, memory, and power years in advance, with revenue arriving much later. The market spent a week categorizing companies: looking at who fills this gap—the company's own cash, customer money, or borrowed money.

This article is the equity section of this week's Pulse report.

Why Stocks Fall Even on Good News

SPY is the market-cap weighted S&P 500, dominated by a few giant tech stocks, up 0.1% for the week. RSP holds the same 500 stocks but with equal weight for each, up 0.8%. QQQ is the tech-concentrated Nasdaq 100, down 1.1%, and the chip stock basket SOXX fell 4.3%. The broader market was bought on Friday; the sell-off was specifically targeted at large AI concept stocks.

When interest rates look harder to cut, these stocks fall the hardest because their prices depend on expected profits years down the line. When rates rise, holding boring alternatives like bonds earns more just by waiting, so every future profit must be discounted against this richer alternative. Investors are not exiting the market—if they were, the equal-weight basket would also fall. They are shedding stocks whose value sits furthest in the future, just as the future has become expensive.

The Funding Gap

A company generates cash from operations and also spends cash on capital expenditures—chips, buildings, and grid access needed for infrastructure. When capital expenditures exceed operating cash flow, the difference must come from somewhere, either new debt, new equity, or the company's reserves.

All three became more expensive last week. The cost of debt is directly the interest rate. The cost of equity financing is higher because interest rates push stock prices down, meaning companies must sell more shares to raise the same amount of money. Spending reserves means forfeiting the interest these reserves could earn now, and interest rises with rates.

Interest rates face two major upward pressures. First, attacks on oil tankers disrupted transport on key routes, pushing Brent crude over $100 per barrel, raising baseline inflation expectations. Second, import prices rose 7.1% year-over-year, driven by cost increases in computers, semiconductors, and industrial machinery. This is exactly the hardware driving AI infrastructure expansion. These pressures limit the Federal Reserve's room to ease monetary policy, with interest rate futures pricing showing a 75% probability of staying unchanged, 25% probability of a rate hike.

Alphabet was strong across all businesses this quarter: Cloud revenue grew 82% to $24.8 billion, Cloud margin expanded from 20.7% to 35.6%, and Search still grew 17%. The stock still fell 7.2% after earnings because Alphabet spent $44.9 billion on capital expenditures, while operating cash flow was only $39.1 billion, a single-quarter gap of $5.9 billion, and then told investors it expects 2026 capital expenditures to be $195-205 billion. No one questions demand, so the sell-off is repricing how the spending is financed.

Oracle reported an annual funding deficit, $55.7 billion in capital expenditures versus $32 billion in operating cash flow (a gap of $23.7 billion), with a financing plan requiring a combination of debt and equity issuance of approximately $40 billion. Despite securing a Pentagon contract worth up to $7 billion, the stock price still touched a 52-week low because money must be spent building data centers before revenue arrives.

Tesla delivered a record 480,126 vehicles, but operating margin compressed to 1.4%. Operating cash was insufficient to cover $5.8 billion in quarterly infrastructure spending, resulting in negative free cash flow of $1.1 billion.

Companies Where Customers Pay in Advance

Companies that preserved market cap all have customers or counterparties who committed via contract to absorb part of the infrastructure costs. First, customer deposits are cash handed over now for future supply, directly financing factories with buyer money. Second, take-or-pay agreements require customers to pay an agreed minimum amount regardless of whether they take delivery, turning future demand into a legal right lenders are willing to lend against. Finally, backlog, which is the pile of signed but undelivered orders, does not provide funding itself, but it eliminates the demand risk that would cause lenders to charge higher fees.

Micron has 16 multi-year take-or-pay agreements, covering about one-fifth of DRAM output until 2030, approximately $100 billion in contractual minimum revenue, and $22 billion in customer deposits. Its customers are paying for it to build factories.

GE Vernova sells turbines and grid equipment, converting electricity demand into power, booking $24.2 billion in orders in a quarter that delivered $11.1 billion in revenue; its $176 billion backlog equals about four years of sold work.

Lockheed's backlog reached $230 billion, about 2.9 years of revenue. Microsoft is the self-funded version of the same escape route: it spent $31.9 billion on capital expenditures, approximately 68% of $46.7 billion in operating cash flow, and still had $15.8 billion in cash remaining after infrastructure. It is running the same infrastructure as Alphabet but does not need external funding.

There are two points to note. Pre-sold revenue is not pre-sold profit. Northrop booked $1.84 in new orders for every $1 delivered, yet profit margin still slipped from 11.8% to 10.6%, because orders may arrive faster than the company can profitably deliver. Moreover, diversification among these companies is thinner than the list of stock tickers suggests: most incremental order growth in memory, chips, and power equipment traces back to the budgets of the same few data centers. This is why Micron, despite having contracts, still fell 6.9% on Friday. Holding memory manufacturers, chip baskets, and turbine manufacturers adds stock tickers faster than it adds diversification.

Microsoft and Amazon Earnings

Microsoft reports earnings on July 29; only if Azure growth is close to 40%, operating income grows faster than revenue again, and capital expenditures climb above $40 billion per quarter, can it remain in the self-funded category. The Federal Reserve also announces interest rate decisions on July 29, so volatility is expected.

Amazon reports earnings on July 30; tracked free cash flow has dropped from $25.9 billion a year ago to $1.2 billion. Its own guidance implies an 11.2% operating margin, versus 13.1% last quarter; if operating income exceeds the $22 billion figure, it will show that the cloud business is filling cash faster than infrastructure consumes it.
