Alphabet, Microsoft and Amazon gave the AI trade what it needed Wednesday: cloud growth that was strong enough to keep the spending story alive. The three companies reported double-digit gains in their cloud-computing units, while Meta’s heavier spending plan was punished in after-hours trading.
The setup mattered because four megacap tech companies reported on the same day, turning earnings night into a referendum on whether AI capex is producing revenue or just bigger data-center bills. Together, those companies have planned $650 billion in 2026 AI infrastructure spending, and the Magnificent Seven account for more than 30% of the S&P 500’s market value.
- Alphabet reported $109.9 billion in revenue, above the $107.2 billion expected, and said Google Cloud grew 63% year over year.
- Microsoft posted $4.27 in earnings per share, topping the $4.06 Wall Street forecast.
- Amazon reported $181.5 billion in revenue and earnings of $2.78 per share, above the $1.64 analysts expected.
- Meta raised its projected capital expenditures to $125 billion to $145 billion, and its stock fell more than 5% after hours.
The split reaction is the market’s current AI rulebook in miniature. Spending is acceptable when cloud revenue is visibly absorbing it; spending is a problem when investors cannot see the same direct payback. Investor’s Business Daily noted that Alphabet, Amazon, Meta and Microsoft all topped views late, but their shares diverged after the reports.
That divergence lands as central bankers are already warning that markets look too comfortable. Bank of England deputy governor Sarah Breeden told the BBC that asset prices are at all-time highs despite major risks, including the possibility that AI valuations readjust alongside stress in private credit and the broader economy.
The clean read-through is that AI has moved from promise to proof-of-revenue, but only for companies with cloud platforms big enough to monetize the demand now. The unresolved item is capex discipline: Alphabet and Meta both revised projections upward, so the market will keep marking each dollar of AI spending against cloud growth, margins and guidance.
