Robinhood has chosen the Nasdaq as the exchange for its eventual initial public offering, according to sources familiar with the matter.

It’s unclear if Robinhood has chosen a direct listing or a traditional IPO, sources said.

Regardless of the method, Robinhood will file an S-1 with the Securities and Exchange Commission.

Robinhood’s brand appears to be intact with bids for pre-IPO shares spiking about the GameStop mania.

Robinhood added gained 3 million users in January alone, according to estimates from JMP Securities.
