What Underdog Fantasy does

Underdog Fantasy (legal entity Underdog Sports, LLC, parent Underdog Sports Holdings, Inc.) is a Brooklyn-based direct-to-consumer sports gaming platform founded in 2020 by Jeremy Levine. The company operates a mobile-first product portfolio across approximately 49 US states, Washington DC, and all Canadian provinces except Ontario. Its core products include Classic Pick'em (player and team prop predictions with payouts up to 5000x), Best Ball season-long fantasy drafts, Streaks (11-pick challenge), Team Picks, Ladders, and Pick'em Champions — spanning NFL, NBA, MLB, NHL, UFC, and PGA.

The platform's distinguishing technology is Underdog Predict, a CFTC-registered Futures Commission Merchant (FCM) offering sports event contracts through a federally-regulated exchange. Following the March 2026 acquisition of Aristotle Exchange DCM, Inc. and Aristotle Exchange DCO, Inc. — CFTC-registered Designated Contract Market and Derivatives Clearing Organization entities — Underdog now operates its own federally-compliant prediction market exchange via its subsidiary UDM Services, LLC, transitioning from its earlier intermediary model with Crypto.com Derivatives North America (CDNA).

The business model is transaction-fee based: Underdog earns entry fees on fantasy contests and a house edge on Pick'em wagers, with no disclosed subscription tier. Customer acquisition is product-led and event-driven, combining a Play $5 Get $50 bonus promo distributed via affiliate and media partnerships (NY Post, Newsweek, podcast sponsorships) with sports team marketing deals (St. Louis Blues, Kansas City Royals, UFL). The company has raised approximately $140M in venture funding across a Series B led by BlackRock and Acies Investment (2022) and a Series C led by Spark Capital (2025), reached a $1.225B pre-money valuation, and reported being on track for nearly $500M in revenue in its fifth year with approximately 4 million cumulative customers. The company is undergoing a strategic pivot from state-regulated sportsbook operations to a federally-regulated prediction markets platform, marked by 20%+ workforce reduction in February 2026 and exits from Missouri and North Carolina sports betting markets.

Expansion highlights6 records

Broad incumbents

• DraftKings: Large incumbent offering both daily fantasy sports and state-licensed sports betting across the US. DraftKings competes with Underdog in season-long and DFS formats and represents the largest scaled operator in sports gaming, though focused on traditional state-licensed sportsbooks rather than CFTC-regulated prediction markets.
• FanDuel: Major incumbent operator in DFS and sports betting, owned by Flutter Entertainment. Competes with Underdog in season-long fantasy contests (FanDuel Fantasy) and represents the closest large-scale competitor in the US fantasy sports market.
• Yahoo Fantasy: Established season-long fantasy sports platform with massive user base. Yahoo Fantasy competes with Underdog's Best Ball draft product, though it is free-to-play and does not offer real-money contests at the same scale.

Direct peers

• Betr: Direct competitor in pick'em-style fantasy sports and micro-betting markets. Founded by Jake Paul, Betr offers similar player prop pick'em contests and was named alongside Underdog in Florida cease-and-desist enforcement actions.
• Sleeper: Mobile-first fantasy sports platform offering season-long and pick'em fantasy contests. Sleeper targets the same mobile-native sports fan demographic and competes with Underdog in best ball and pick'em formats.
• Fliff: Social sportsbook offering free-to-play and pick'em style contests targeting a similar casual sports-fan demographic. Fliff competes in the same entry-level sports engagement market as Underdog's Pick'em products.
• Kalshi: CFTC-regulated prediction market exchange and direct competitor to Underdog Predict. Kalshi offers event contracts on sports, politics, and economics, and is the primary federal-regulated exchange competing for the same sports prediction market users.
• PrizePicks: Direct competitor in daily fantasy sports Pick'em market. PrizePicks offers the same player prop and stat-based pick'em contests that constitute Underdog's core product, serving the same sports-fan customer base. Both have faced similar state regulatory scrutiny, with Florida cease-and-desist letters targeting both companies.

Emerging players

• Polymarket: Cryptocurrency-based prediction market platform offering event contracts. While focused primarily on political and economic events, Polymarket represents an emerging competitor in the broader prediction market space that Underdog is entering.
• Novig: Commission-free sports prediction market and exchange competing in the same CFTC-regulated prediction market category as Underdog Predict. Novig targets similar sports prediction use cases with a peer-to-peer exchange model.
