Underdog CEO: Handle Surging via Prediction Markets
Prediction-market wrapper drives nationwide handle growth for Underdog in September 2026.
Underdog's customer handle is climbing sharply as the platform uses prediction markets to distribute sports betting-style products into states where traditional sportsbooks cannot operate, according to Legal Sports Report.
Why It Matters
Prediction markets have emerged as a genuine regulatory arbitrage tool, letting operators like Underdog reach bettors in restricted jurisdictions without a full sportsbook licence. As of September 2026, Underdog's CEO confirmed handle growth is accelerating — a direct signal that the prediction-market wrapper is converting casual users into active, repeat bettors. For the broader industry, this validates a model that DraftKings, FanDuel, and Kalshi are all watching closely. Players in states without legal sports betting now have a functional alternative, though they should note that all wagering products carry financial risk.
Context
Underdog built its brand on fantasy sports and player-prop contests before pivoting toward prediction markets as a growth vehicle. Prediction markets occupy a different legal lane than sportsbooks — regulated federally by the CFTC rather than at the state level — which allows nationwide reach that traditional operators cannot match without a patchwork of individual state licences. The strategy mirrors moves by Kalshi and Robinhood Markets, which have also expanded sports-event contracts under federal oversight in 2026.
What's Next
Watch for Underdog to announce new product verticals or market categories as handle momentum builds; sustained volume growth typically triggers competitor responses on pricing and promotions. A formal handle figure or quarterly disclosure would be the next concrete data point to confirm the scale of this surge.
