Last Week Ignite August 2, 2026
Everybody's Earnings Ran Through Anthropic
Microsoft and Amazon just told investors where a chunk of their earnings beat came from: marking up a private company neither of them can sell.
Microsoft booked a $3.2B gain on its Anthropic stake this quarter, close to two thirds of its headline beat. Amazon’s net income more than tripled to $62.6B, and the company says $53.4B of that was non-operating income primarily from Anthropic. Neither company files a 10-Q for Anthropic. Both just moved their own stock on its behalf.
That’s the throughline in this week’s Last Week Ignite. A few more findings:
Private AI exposure and public tech exposure stopped being diversified bets. Right now they’re largely the same bet wearing two tickers.
The open-weight price war inverted. Kimi K3, the strongest open-weight model available, now costs roughly 12x more per completed task than OpenAI’s cheapest closed model, and runs about 5x slower. Free weights stopped meaning cheap inference.
Anthropic’s own Frontier Red Team combed through 141,000 evaluation transcripts looking for a containment failure, and found three real breaches at three real companies. None of the three had noticed on their own.
