This week the biggest technology companies opened their books and showed investors what their artificial-intelligence spending is actually buying. The market did not react as one. It split down the middle.
On one side sat the clear winner. Microsoft reported 43% growth at its Azure cloud business, and its shares jumped as much as 17%. That added close to $450bn of market value in a single day, the largest one-day gain in stock-market history. The message was simple: Microsoft’s AI spending is now showing up as cloud revenue that customers are actually paying for, not merely as a promise of future returns.
On the other side, the hardware behind all of it was in retreat. The 20 most valuable chip stocks lost about $1.3tn over the week, with Nvidia alone shedding roughly $238bn. Memory makers including SK Hynix, Samsung and Micron each dropped more than $100bn as well. Analysts described the selloff as a “loss of confidence” rather than a change in the underlying fundamentals of the AI trade, but the scale of the damage was a reminder of how much of the stock market’s AI optimism had been concentrated in a handful of semiconductor names.
Cloud gets paid. Capex gets questioned.
The dividing line was whether the spending had turned into something customers pay for. AWS grew 37% and lifted its operating margins, and Amazon’s stock rose as a result. Yet the company’s free cash flow over the past year turned negative for the first time since 2023, as record data-centre spending piled up. The market chose to focus on the revenue growth, but the balance-sheet strain is a warning sign that even the most successful AI cloud providers are running hard just to stay in place.
Even the good numbers deserved a second look. Much of that standout AWS margin came from a one-off $600m gain on energy hedges, not from the cloud itself. Strip it out and the figure lands back inside the analyst range, a reminder that reported beats can flatter the underlying trend. Energy is becoming a central battleground for AI infrastructure, and hedging gains are not a sustainable source of profitability.
The same tension ran through the entire earnings season. Investors cheered the revenue and frowned at the bill. A year ago the market rewarded almost any capital-expenditure number as proof of ambition. Now the same numbers are being interrogated for payback timelines, contract visibility and the durability of demand. The shift marks the end of the hone
