Barstool's Portnoy rips Robinhood as 'biggest frauds of them all' after GameStop trading restrictions

Robinhood restricted trades of GameStop, AMC Entertainment, Bed Bath & Beyond, BlackBerry

Barstool Sports founder Dave Portnoy went on a tirade Thursday against mobile brokerage app Robinhood after it restricted transactions of certain volatile securities.

Robinhood, TD Ameritrade and others restricted trading on Thursday and Wednesday, respectively, following an unexpected surge in trading volume of shares of GameStop, AMC Entertainment, Bed Bath & Beyond, BlackBerry and others.

"I will burn @RobinhoodApp to the ground if they shut down free market trading," Portnoy said in a Thursday tweet.

He also tweeted directly at Robinhood cofounders Vladimir Tenev and Baiju Bhatt, saying he hopes Tenev goes "to jail."

Robinhood said in a Thursday press release that it was "restricting transactions for certain securities to position closing only, including $AAL, $AMC, $BB, $BBBY, $CTRM, $EXPR, $GME, $KOSS, $NAKD, $NOK, $SNDL, $TR, and $TRVG" and "raised margin requirements for certain securities."

"Amid significant market volatility, it’s important as ever that we help customers stay informed," the app popular among new and young traders said.

One Robinhood user filed a lawsuit against the app Thursday for "purposefully, willingly, and knowingly removing the stock GME from its trading platform in the midst of an unprecedented stock rise."

Portnoy added in another tweet that Ameritrade's restrictions were expected but Robinhood's "entire business model is to cater to the exact people they are now trying to f--k with and scare into selling. They will never recover from this."
