The chain runs on one number
The chain runs on one number: Anthropic makes about $100 billion per gigawatt of compute. That is why it can pay SpaceX roughly $50 billion a gigawatt at the spot price. SpaceX can then pay $30 billion to Nvidia for chips, and Nvidia can pay TSMC, Micron, and SK Hynix.
The dead man's switch
The biggest customers also act as a dead man's switch, the handle a train driver has to hold down: if the hand comes off, the train stops. OpenAI has already scaled back its buildout ambitions from about $1.4 trillion to $600 billion. If Anthropic stops, the buildout slows with it.
When a pileup happens
A pileup happens only if the brakes go on because demand is missing. If Anthropic is simply passed by SpaceX, OpenAI, or another American lab, the compute still gets used and nothing piles up. Once Anthropic is public, its quarterly numbers would be vetted and GAAP-compliant, which makes them the signal the whole industry watches.
How does a dead man's switch stop a train?
The device requires the driver to keep pressing a pedal or holding a handle. If pressure is released, a valve opens and the brakes apply automatically. Many railways add a vigilance system that sounds a warning after a pause and applies the brakes if the driver does not respond. Early versions appeared on electric trams and trains in the early twentieth century.
Why do small demand changes swing suppliers so hard?
Jay Forrester of MIT showed in his 1961 book Industrial Dynamics that delays in supply chains amplify small changes in demand as orders travel upstream. The effect later became known as the bullwhip effect. Hau Lee and colleagues analyzed it in a widely cited 1997 paper, tracing it to order batching, demand forecasting, and shortage gaming. Each link in the chain overreacts a little, so suppliers farthest from the customer see the largest swings.
How does a pace car control a race?
When a crash or hazard appears, the pace car pulls onto the track and the field lines up behind it at a controlled speed. Racing is suspended and passing is not allowed. Drivers must hold position until the track is clear and the pace car leaves. The pace car first appeared at the Indianapolis 500 in 1911, when it led the first rolling start.
