Recently, FTX CEO Sam Bankman bought a 7.6% stake in $HOOD. FTX is a crypto brokerage platform similar to $COIN.

Being an expert on how exchanges work, it would be interesting to see what Sam Friedman looks to do with Robinhood. Even if his stake in the company may seem insignificant, it's important to note that FTX and Robinhood are indirect competitors. Both offer a crypto brokerage platform to consumers but at the same time, Robinhood offers fewer cryptos for people to trade and gives people a plethora of stocks and options to buy and sell.

The reaction to Sam Bankman's stake in Robinhood was big. The stock rose more than 20% after hours because of it.

In late March, $GME experienced a similar reaction as Ryan Cohen, co-founder of $CHWY, added to his stake in the videogame retailer. Around the same time, $BBBY shares surged as Ryan Cohen took a stake in that company as well.

Ryan Cohen is investing in those retailers because he wants to help fix the operations of those companies. Sam Friedman could be looking to do something similar with Robinhood.

We have yet to see.
