Bloomberg reported that the US Commodity Futures Trading Commission (CFTC) sent letters to some prediction market platforms, warning them not to use American-style gambling odds. American-style gambling odds are a method of odds notation that uses '+' and '-' symbols to indicate how much one can earn for a given wager. The CFTC delivered a warning reminding regulated entities to comply with US laws related to derivatives trading and not to engage in 'deceptive' practices when listing, soliciting, or advertising products.
