“It is against the law to solicit U.S. persons to buy and sell commodity options, even if they are called ‘prediction’ contracts, unless they are listed for trading and traded on a CFTC-registered exchange or unless legally exempt. The requirement for on-exchange trading is important for a number of reasons, including that it enables the CFTC to police market activity and protect market integrity. Today’s action should make it clear that we will intervene in the ‘prediction’ markets, wherever they may be based, when their U.S. activities violate the Commodity Exchange Act or the CFTC’s regulations.”
