You can already create a synthetic short position on Robinhood using options. Between a wide call option credit spread and a put option on the same date, you can short it. Selling a call option and buying a put option at the same strike price creates the synthetic short.

Understand that with shorting a stock, you have limited potential gains and unlimited potential losses.
