Dan Shak, who was quite active at the 2022 World Series of Poker (WSOP), was charged by the Commodity Futures Trading Commission (CFTC) with "spoofing," a term for when securities buyers place market orders and then cancel them before the order is fulfilled. Spoofing is illegal and can carry steep penalties.
The high-stakes poker player is alleged to have repeatedly placed orders on gold and silver futures with the intention to cancel them before execution, and this isn't the first time he's been in trouble with the CFTC.
