Nearly $2 trillion swung across six megacap technology stocks last week, as Amazon, Microsoft and Alphabet gained about $1.5 trillion while Apple, Meta and Tesla fell.
Key Points:
- Roughly $2 trillion moved into or out of six megacap technology stocks during earnings week.
- Amazon lifted 2026 capital spending to about $220 billion and its stock still climbed.
- Jefferies sees megacap AI spending trending toward almost $800 billion over the next 12 months.
Big Tech Earnings Split Wall Street
Investors moved roughly $2 trillion into or out of the six megacaps that have reported results this season, and the divide came down to one test: proof that customers already pay for the artificial intelligence capacity being built.
Microsoft added more than $600 billion in market value over the week. Amazon and Alphabet each picked up more than $400 billion.
Apple lost more than $350 billion after component shortages clouded its guidance, and Meta sank 8% on Thursday as investors questioned the payoff from its buildout, even with revenue up 28% to $60.8 billion.
Tesla shed about $7 billion following negative free cash flow and a forecast for heavier spending on autonomous driving, manufacturing and AI infrastructure.

Cloud Revenue Sets The AI Payback Test
Jefferies banker Jason Greenberg said Friday that megacap AI spending is trending toward almost $800 billion over the next 12 months. Adoption is no longer the sticking point, he said. The unresolved question is whether that demand turns profitable enough over time to justify the scale of the buildout.
Cloud revenue became the scoreboard.
Amazon Web Services climbed 36.7% from a year earlier, its quickest pace in 18 quarters, and the backlog of signed but unbilled cloud contracts reached $496 billion from $364 billion a quarter earlier. Microsoft showed similar strength in Azure, where growth accelerated to 43%, and the stock added almost $450 billion in one session, the largest single-day gain any company has posted.
AI Capital Spending Faces New Scrutiny
Amazon lifted its 2026 capital expenditure plan to about $220 billion from $200 billion, and the stock still finished the week up almost 17%. Meta raised the floor of its own spending range without pointing to outside customers, and quarterly free cash flow fell to $784 million from $8.55 billion a year earlier.
Tim Cook warned that memory shortages left Apple with few options, and the shares dropped close to 10% on Friday.
The pattern formed earlier in July, when Alphabet guided 2026 capital spending to a range of $195 billion to $205 billion and set off a selloff that dragged the other hyperscalers down with it. Forecasts have climbed steadily since the spring, when tallies of the four largest spenders sat near $650 billion for the year, and several Wall Street firms now expect industry capital spending to pass $1 trillion in 2027.
