Deep dive
The two opposites side by side, seeking to understand rather than judge. These are possible readings of the coverage, built from the articles linked on this page; they are not claims about anyone's motives. How we write it.
Seen from the left
“Alphabet tanks nearly 13% for worst day ever, losing $500 billion in value” CNBC
A possible reading: the AI spending race concentrates power and risk in a few firms.
May be protecting: ordinary savers exposed to a bubble.
Seen from the right
“Google Stock Craters 12% on Disappointing Earnings, Wiping Out $500 Billion in Shareholder Value” Breitbart
A possible reading: markets are doing their job, pricing risk and punishing weak returns.
May be protecting: investors' freedom to bet on the future.
What they agree on
Alphabet lost about $500bn in value after weaker profit while AI spending stayed high. Both want returns to justify the spending.
Where they truly differ
Whether AI spending is a bubble or long-term investment.
The paradox
The AI that drives the spending may also threaten search, Google's core business.
Open questions
- How much are the big firms spending on AI this year?
- Which revenues are actually coming from AI?
- Shared question: what would show that AI spending is paying off?

Alphabet Shares Plunge 12% After Earnings Miss
The drop came after Google's parent reported third-quarter revenue of $127.6 billion, up 25 percent but below analyst targets. Search ad growth slowed to 12 percent at $63 billion, hit by AI answers that cut ad revenue per query despite record query volume. Google Cloud doubled in growth thanks to AI demand, but $51.4 billion in spending flipped free cash flow negative at $9.1 billion, fueling worries over big tech's AI costs.
