The one number Musk can't hide in the S-1 (Ad)

When SpaceX files its S-1 in June, one number will stand out - power consumption. Running 1 million GPUs requires more electricity than some small countries use in a year, and SEC rules require it be disclosed. When that figure goes public, every analyst on Wall Street will race to identify the supplier. One small company already has a $1.5 billion backlog - and Dylan Jovine has the name and ticker.tc pixel
