A thread on facts 1/X

In our 20-minute interview with Robinhood CEO Vlad Tenev I tried to push for answers tied to their decision in 2018 to internalize a boring but important part of users' trades to boost revenue

Their decision came with a tradeoff: A spike in volatility could be very, very bad 2/X

It's a behind the scenes part of your trade, but Robinhood or E*Trade passes your stock order to what's called a clearing house

They carry some liability in the days it takes for your trade to settle. That usually isn't a problem, but can become one if a stock swings fast 3/X

But Robinhood in 2018 decided to cut ties with Apex to build their own clearing house called Clearing By Robinhood 4/X

Building your own clearing house is ambitious. TD Ameritrade and Schwab built their own but they are industry titans

In Robinhood's own blog they trumpeted their achievement as the "only clearing system built from scratch, and on modern technology, in the last decade." 5/X
