AWS Jumps 37% and Amazon $AMZN Is Winning the Chip War
Bloomberg and Seeking Alpha creators are all saying the same thing: Amazon's Trainium bet is paying off in ways the market hasn't fully priced in
Ticker Ratings
While everyone was busy debating whether $MSFT deserved its 17% single-day surge, Amazon quietly dropped what might be the cleaner earnings story of the week. $AMZN reported AWS revenue of $42.2 billion, up 37% year-over-year, beating analyst estimates of $40.6 billion and marking the fastest cloud growth since Q4 2021. Multiple Bloomberg Talks and Bloomberg Tech breakdowns all landed on the same point: this wasn't a fluke quarter, it was an acceleration.
The detail analysts keep circling back to is the chip strategy. Amazon's custom silicon, Trainium, alongside Google's TPUs, gives both companies a structural cost advantage over Microsoft by reducing dependence on $NVDA GPUs. Bloomberg analysts noted that Amazon and Google can handle AI workloads more cheaply per token, which matters enormously as enterprise customers grow increasingly price-sensitive. The AI services and custom chip businesses each carry a $25 billion annual revenue run rate, a number that barely gets mentioned in the headlines but probably should be.
Then there's advertising, the part of Amazon that keeps quietly getting better. Ad revenue grew 26% this quarter, a meaningful step up from the roughly 20% growth investors had gotten used to. Analysts flagged that some of this could be pull-forward from Prime Day shifting into Q2, so watch that number carefully next quarter before declaring a structural acceleration.
The retail segment got a similar calendar boost, with online revenue growing 15% versus the expected 13.7%, partly because Prime Day moved from Q3 into Q2 this year. That's a real tailwind, but also a real comp problem for Q3. The bull case here is that AWS margins expanded despite heavy infrastructure investment, which directly contradicts the bear narrative that AI capex would crush profitability. The bear case is that some of the retail and ad strength is borrowed from next quarter.
Meanwhile, Bloomberg's coverage of the broader earnings week framed Amazon as the less glamorous but more financially coherent story compared to Meta, which posted $60.8 billion in revenue but saw $META EPS miss on a $2.4 billion legal reserve while simultaneously committing to up to $145 billion in capex. Zuckerberg is playing a longer game; Amazon is winning the current one.
If AWS margins can hold while the company continues cutting Nvidia dependency, Amazon might be the AI infrastructure trade that doesn't require you to believe in a five-year moonshot. It's already happening on the income statement.
