Deeply-funded fintech company Robinhood has been the world’s most-discussed startup over the last week. After the discount trading pioneer found itself in the midst of a battle between hedge funds on one side and a slurry of retail and institutional capital on the other, Robinhood’s trading volume spiked last week.

But after the National Securities Clearing Corporation (NSCC) raised its deposit requirements before the market open on Friday, Robinhood was forced to restrict trading in a number of popular stocks. The company also drew down its credit lines and raised new capital from prior investors to stay open during a trading avalanche.
