DraftKings stock rises on prediction market ruling; analysts call it rational
DraftKings' stock has rallied on news that negatively impacts prediction markets, a disconnect noted by CEO Jason Robins. Following a 9th U.S. Circuit Court of Appeals ruling stating sports event contracts are not swaps and not under CFTC jurisdiction, DraftKings shares rose over 7%, and Flutter over 6%. Robins, having launched DraftKings' prediction market exchange DKeX in June, expressed confusion over the stock reaction, as prediction markets are a growth area for the company. Analysts view the market's response as rational, noting DraftKings' core revenue comes from sportsbooks. Bernstein's Ian Moore highlights DKeX's potential, ranking third in prediction market volume and projecting $1 billion consumer volume by December. Investors are waiting to see if DKeX can sustain growth through the fall sports seasons and compete with Polymarket and Kalshi.
