Robinhood, one of the largest online brokerages, has grappled with an extraordinarily high volume of trading this week as individual investors have piled into stocks like GameStop. That activity has put a strain on Robinhood, which has to pay customers who are owed money from trades while posting additional cash to its clearing facility to insulate its trading partners from potential losses.
“As a brokerage firm, we have many financial requirements,” Robinhood said in a blog post Thursday. “Some of these requirements fluctuate based on volatility in the markets and can be substantial in the current environment.”
