Revenue at Robinhood Markets more than doubled in the second quarter thanks to a torrent of customers trading cryptocurrency, but the company posted a big loss due to an emergency funding deal earlier this year.

The trading app recorded a loss of $502m, or $2.16 per share, on revenue of $565m in its first earnings report since its July initial public offering. In the second quarter of 2020, Robinhood generated a profit of $58m on revenue of $244m.
