$NVDA CEO Jensen Huang requested to brief Congress on his relationship with reported PRC intelligence asset Alice Huang.
We wrote about this in May.

9) $NVDA CEO Huang has walked alongside Megaspeed at every step, and seems to have a close relationship with Megaspeed's Alice Huang. They partied together in June 2024 - same month as the Apex/Alibaba pledge, then dined together in May 2025 - just after U.S. trade restrictions.

“Water cooling is a newer innovation that started at Cerebras”
Cooling heavily affects how reliably a chip operates and how quickly in ages.
When you have a larger than average chip (say, the size of a dinner plate), you get a pretty tricky engineering problem.
This is how we solved it at @cerebras .
Historically, AI data centers, especially ones retro-fitted from the crypto mining era used air cooling. These are the extremely loud, higher energy consumption data-centers that are slowly being phased out.
Water cooling, is a newer innovation that started at Cerebras and has since scaled to be implemented in NVIDIA and AMD datacenters as well. But is still tricky for such a large wafer. There are three things that we did.
1. Instead of the water flowing parallel across the chip (the chip is too big), water flows straight towards and away from the wafer
2. Each channel runs down close to the wafer without touching it, turns, and comes back out. Because every path is short, the outlet temperature is still close to the inlet temperature.
3. A custom cold plate to reduce thermal resistance between the wafer and the water.
A lot of these are innovations that took many years to invent, by some of Cerebras' founders like JP, Sean Lie, and continue to improve.

14) Before that, $CBRS CEO Feldman was at Riverstone, which received SEC charges, while Feldman plead guilty to one felony count of violating internal accounting controls. Riverstone would go bankrupt and return just $1.06 per share to shareholders, 92% lower than its spin-off.
15/15) We estimate $CBRS private investors paid ~$23/share - far lower than todays prices... Insiders have sold $400M+ since the IPO. 19.4M shares unlocked today, and over 50M more will unlock in early November.
We are short and think shares are headed lower.
