The Q3 2025 earnings season has concluded for the majority of Big Tech’s most dominant players (just NVDA left on November 19!), and the results have confirmed that the AI arms race is in full swing, driving explosive growth for some while leading to staggering costs for others.

In a flurry of reports that ended Thursday, Alphabet, Amazon, Apple, and Microsoft all posted massive, better-than-expected quarters, collectively proving their dominance. However, Meta delivered a sobering reality check, warning that the price of competing on AI will be "notably larger" than anyone imagined, sending its stock tumbling despite strong revenue.

Here’s some thoughts on those reports.

The Cloud Kings: Amazon, Alphabet, and Microsoft

For the three companies powering the world's cloud infrastructure, the quarter was a resounding victory, with all signs pointing to their massive AI investments paying off.

On Wednesday came a double-whammy of Alphabet (GOOGL) and Microsoft (MSFT) earnings. Alphabet set a new milestone, reporting its first-ever $100 billion quarter. The company crushed estimates with $102.3 billion in revenue, a 16% jump from the prior year. The star of the show was Google Cloud, which grew a staggering 34% to $15.2 billion as its AI infrastructure and generative AI tools for enterprises gained significant traction. Search and YouTube also posted strong double-digit growth.1

Similarly, Microsoft continued to prove it is successfully monetizing its AI lead. The company beat estimates across the board, driven by a 40% surge in its Azure cloud services revenue. While Microsoft took a $3.1 billion charge related to its massive investment in OpenAI, the partnership appears to be fueling growth across its ecosystem, with strong demand for its AI-powered Copilot products.2

Amazon (AMZN) was the week's biggest surprise, reporting its earnings Thursday afternoon. After months of investor anxiety about slowing cloud growth, Amazon announced that its Amazon Web Services (AWS) division re-accelerated, with revenue jumping 20% to $33 billion. The news, which CEO Andy Jassy said marked a growth pace "we haven't seen since 2022," sent the company's stock soaring 11% in after-hours trading. The company also posted a huge beat on the top and bottom lines, with $180.2 billion in revenue and EPS of $1.95, bolstered by a 24% surge in its high-margin advertising business.3
