DraftKings shares declined roughly 14.6% over the past 30 days, falling from about $24.78 to around $21.17 and extending a broader year-to-date selloff. The slide accelerated after Needham data showed prediction-market rival Kalshi holding a dominant share of NFL Week 1 volume, far outpacing DraftKings' own DKeX exchange.
