The US commodities regulator’s chief enforcement director sent a cautionary message to prediction market insider traders on Tuesday, vowing that violators will face enforcement action.
“We are aware of the speculation about insider trading,” CFTC enforcement director David Miller said at a panel at New York University on Tuesday. “We are watching.”
“There’s a myth in mainstream media and social media that insider trading doesn’t apply in the prediction markets … That is wrong.”
Miller, a former federal prosecutor who was appointed to the position on March 2, said the Commission will use its prosecutorial discretion and will not dedicate resources to “trivial” cases.
“We will only be prosecuting cases against those who tip or trade with misappropriated information,” he said, according to Bloomberg.
Prediction market insider trading has become a top-of-mind issue among US lawmakers in recent months, threatening the credibility of an industry that recently exceeded $20 billion in monthly volume, according to TRM Labs.
Event contracts are “swaps,” not gaming
“Our position is that event contracts are not gaming. The event contracts at issue are swaps. Insider trading law applies,” Miller said, according to Reuters.
He said that the Commission will also focus on a few core enforcement areas, including market abuse and violations of laws designed to prevent money laundering.
