The GPU Resale Market Is Now a Leading Indicator. It's Flashing.
Secondhand accelerator prices turned before the last two capex wobbles. This month they turned again.

There is a market most investors never watch that has called the last two turns in AI capex4: the price of a used accelerator, overwhelmingly Nvidia's. When labs over-order and demand softens, the secondhand rack shows it first. This month, secondhand prices turned down.1
The logic is clean
The logic is clean. New silicon is allocated, contracted, and opaque. Used silicon clears in the open, so it prices in real time.3 When a resale card trades below its depreciated book value, someone is dumping capacity, and dumping is a demand signal, not a supply one.
The counter-read matters too
The counter-read matters too. A soft resale price can mean new supply finally loosened5, not that demand cracked. The two look identical for about a quarter, and the difference is the whole trade.
What tips it is who is selling
What tips it is who is selling6. When it is failed startups liquidating, that is noise. When it is well-capitalized labs quietly returning leased capacity2, that is the tell.
The indicator is early, not precise. It flashed before the last two wobbles and was also wrong once. Treat it as a smoke alarm, not a verdict.
