NEW YORK – The boundary between prediction markets and traditional sports betting has blurred further this week. As Robinhood rolls out its parlay-style “Custom Combos” just in time for the NFL playoffs, traditional giants DraftKings and Flutter (FanDuel) are reporting massive fourth-quarter earnings boosts fueled by high betting margins.
Prediction Markets Evolve: Robinhood Targets the “Parlay” Crowd
On January 16, 2026, Robinhood officially launched “Custom Combos,” a feature allowing users to create multi-leg prediction contracts on NFL games. While “conceptually” similar to a sportsbook parlay, Robinhood emphasizes a critical structural difference:
- Peer-to-Peer Pricing: Unlike sportsbooks where odds are set by a centralized bookmaker, Robinhood’s payouts are dictated by market activity. Users take the other side of the contract, effectively trading against each other.
- Expanding Scope: Initially limited to 10-leg NFL contracts, Robinhood plans to expand combos to economics, weather, and cultural events.
- Volume Surge: The launch follows record activity in the sector. Kalshi, Robinhood’s backend partner, reported a staggering $702 million in NFL trading volume last week alone.
The Margin War: Sportsbooks Rebound in Q4
While prediction markets are capturing retail interest, traditional sportsbooks are proving their financial resilience. According to a note from Macquarie, both Flutter and DraftKings are expected to beat Q4 earnings expectations thanks to a sharp rebound in NFL “hold” (the percentage of wagers kept by the house).
- DraftKings: Implied hold rates rose to 9% (up from 8.5% guidance), potentially adding up to $100 million in additional EBITDA.
- Flutter (FanDuel): Achieved a dominant 12% hold for the quarter, far exceeding the 11% forecast. This could result in a $200 million earnings beat, bringing quarterly EBITDA to approximately $450 million.
- Stock Recovery: Shares of both companies had struggled earlier in 2025 due to “customer-friendly” NFL results, but the late-season margin surge has restored investor confidence ahead of February earnings reports.
“Traditional parlay bettors are beginning to realize they may find better pricing on prediction markets like Kalshi or Polymarket, as they are not paying the centralized house margin.” — Adam Robinson, Professional Bettor
Industry Outlook: Incremental Growth or Direct Threat?
Analysts are currently divided on whether prediction markets are cannibalizing traditional sportsbooks. Macquarie’s Chad Beynon argues that prediction platforms currently account for only 5% of legal handle and thrive primarily in non-legal betting states, making them an “incremental” rather than “competitive” threat.
However, as prediction markets introduce sophisticated features like custom parlays and live prop contracts, the structural advantages of their peer-to-peer model could force traditional operators to innovate even more aggressively on pricing and product variety.
