According to The Financial Times, U.S. internet broker Robinhood has removed some event contracts in its fast-growing prediction market business that could potentially lead to market manipulation and insider trading. Jordan Sinclair, President of Robinhood UK, said the company is highly focused on the risk of market abuse and has explicitly refused to offer contracts such as “Mention Markets.” These markets allow users to bet on specific keywords that appear in particular speeches or earnings call transcripts. Because they are extremely susceptible to being controlled by insiders, related editors have previously been punished for insider trading.
