Prediction-market event trading reshapes sports betting; DraftKings leads amid Super Bowl surge

Leap to event trading reshapes sports-betting market

Prediction-market platforms are driving a new growth front for sports-betting firms, with activity around the Super Bowl illustrating where DraftKings and peers see expansion. Kalshi reports record downloads — up 1,544% year‑over‑year during Super Bowl week — and daily active users near 2 million on game day, while Robinhood, Polymarket and BetMGM also post sharp increases. DraftKings remains a scale leader in the space with about 5 million daily active users, and executives across the industry frame event contracts as complementary to traditional sportsbooks rather than as cannibalising them.

Sporting events and pop culture tie-ins compound the opportunity. Kalshi says more than $1 billion flows through its platform for the Super Bowl and highlights culture markets — such as who performs for halftime — that attract large single-market volumes (Kalshi cites more than $100 million in a Bad Bunny performance market). Firms argue that presenting many trading options for a single event keeps users engaged on platform and that non-sports markets (financial, weather, pop‑culture) broaden use cases beyond bets on game outcomes.

For DraftKings, the surge in event contracts presents product and distribution levers rather than a sequence of price moves. Companies are exploring ways to offer event contracts in states where traditional sports wagering is not yet legal, using prediction markets and novelty contracts to reach new users and deepen engagement ahead of major sports calendars. Industry watchers say the build-out of markets, product integrations and marketing investments will define winners as firms seek to convert episodic spikes (Super Bowl, Olympics, World Cup) into sustained usage.

Rising competition and spending

Competition is intense, with Kalshi outpacing rivals on marketing spend: Sensor Tower estimates show Kalshi outspends Polymarket in the U.S. by roughly 19 times and DraftKings by about 35 times, prompting what industry observers call a marketing arms race as firms compete for attention around marquee events.

Calendar tailwinds into 2026

A packed sports calendar — Winter Olympics, NBA All‑Star Weekend, March’s NCAA tournament and a summer World Cup with 104 games — gives operators recurring high-volume opportunities. Executives expect those events to push contract volumes higher and to attract new users ahead of and through 2026.
