GameStop and the Stock Market's Hidden Plumbing: Why the Buy Button Went Dark

In this episode of Money Lessons, Andy uses the 2021 GameStop saga to reveal the hidden machinery that runs underneath every stock trade. He explains how a struggling video-game retailer became the most heavily bet-against stock on Wall Street, why ordinary investors banded together to buy it, and how its price rocketed from about $17 to around $483 in a matter of weeks. Then he answers the question that left millions of people furious: why did Robinhood suddenly stop letting them buy? The culprit turns out to be the market's plumbing — the two-day settlement delay, the clearinghouse that guarantees every trade, and the collateral deposit that exploded into the billions when prices swung wildly.
