Prediction markets like Kalshi and Polymarket are suddenly drawing sports bettors, policy wonks and everyday speculators into the same arena, and that puts fresh pressure on traditional sportsbooks such as DraftKings. A fast growing rival model can unsettle old economics, but it can also reshape where capital flows next. This piece walks through 3 US online betting stocks exposed to that shift and what that might mean for your watchlist.
The three stocks covered below are just a first cut, and the full screen surfaced 8 more US online sports betting and iGaming platforms with equally compelling narratives that are not covered in this article. To identify which tickers best fit your own thesis, head straight into the US Online Sports Betting and iGaming Platforms screener to filter, analyze, and focus on your highest conviction plays.
Overview: DraftKings runs a digital betting platform that lets customers place sports wagers, play online casino games, try daily fantasy contests and use prediction markets.
Operations: DraftKings generates about US$6.2b in Business-To-Consumer revenue, primarily from its online sportsbook, iGaming and related digital wagering services.
Market Cap: US$9.7b
DraftKings sits right where this screener theme lives, since its sportsbook, iGaming and prediction products turn growing betting interest into a single, integrated trading style experience for retail users.
“Expansion of DraftKings Predictions as a vertically integrated product, with over 600,000 customers year to date 2026 and annualized traded volume rising from US$2.3b in April to US$11b in July, positions the brokerage, DKeX exchange and in-house market maker stack to support higher revenue density and potentially stronger net margins over time.”
The real swing factor is how one emerging regulatory and cost pressure shapes the profitability that those higher volumes hint at.
That profitability question is where it gets interesting. The full narrative for DraftKings unpacks how regulation, prediction volumes and product mix could be accelerating or quietly capping DraftKings’ upside.
NasdaqGS:DKNG Earnings & Revenue Growth as at Oct 2026
Overview: Rush Street Interactive runs BetRivers, PlaySugarHouse and RushBet online casinos and sportsbooks, offering real-money gaming across the Americas.
Operations: Rush Street Interactive records about US$1.37b in online gaming and retail sports betting revenue, with roughly US$1.09b from the US and Canada.
Market Cap: US$4.4b
Rush Street Interactive fits this screener because it is built around regulated online casinos and sportsbooks where prediction-style wagering can sit alongside traditional bets.
“Expansion into online gaming and betting is associated with strong user growth and a broader geographic reach.”
For investors, a key consideration is how unresolved regulatory and tax pressure ultimately affects margins on that growing handle.
Those margin questions are exactly where the full narrative for Rush Street Interactive pulls apart tax drag, product mix, and prediction market pressure that may be masking how Rush Street Interactive is really positioned.
NYSE:RSI Revenue & Expenses Breakdown as at Oct 2026
Overview: Flutter Entertainment owns FanDuel and other betting brands that run US-focused online sportsbooks, iGaming, fantasy sports and betting exchanges.
Operations: Flutter generates most of its revenue from the US at about US$7.0b, with sizeable contributions from Southern Europe and Africa at roughly US$3.5b, the UK and Ireland at about US$3.6b, and Asia Pacific at around US$1.4b.
Market Cap: US$13.8b
Flutter Entertainment matters for this screener because FanDuel is one of the main on-ramps into regulated US sports betting, casino style play and emerging prediction features that look increasingly similar to what retail traders see on newer exchanges.
“Ongoing expansion of online gambling and iGaming in newly regulated and high-growth markets (for example, Brazil and the U.S.) is expected to accelerate Flutter’s revenue and earnings, leveraging increasing global internet and smartphone penetration and regulatory liberalization.”
What really moves the needle for Flutter Entertainment is how one unresolved regulatory and tax pressure shapes the profit pool behind that growing engagement curve.
That profit pool tension is exactly where the full narrative for Flutter Entertainment shows how regulation, prediction volumes and product mix could be accelerating Flutter Entertainment’s earnings power while masking key risks.
