Underdog Overview
Underdog is best known for its Pick'em-style daily fantasy contests, but its Predict arm now allows players to trade on yes/no contracts in the same way as Novig, Kalshi and Polymarket.
What sets Underdog apart is that it now owns its own regulatory infrastructure, Underdog Exchange (UDX), which is built on Aristotle Exchange, a CFTC-registered designated contract market and derivatives clearing organization. That means Underdog is one of the only sports trading companies in possession of their full prediction-market license stack rather than routing trades through a third-party venue, giving them full autonomy. Some markets are still powered by partner exchanges, including Crypto.com Derivatives North America and Kalshi, depending on the contract.

Underdog Predict: Platform Review
You can make real prediction trades and play their fantasy platform with a single account, login and wallet. From the home feed you can browse live and upcoming markets and trade Moneyline, Spread, and Total contracts, or combine picks into a single trade, which works the same way a Parlay bet does.
Markets
Underdog Predict covers a wide sports slate, including:
- NFL and college football
- NBA and college basketball
- MLB
- NHL
- Soccer (World Cup, EPL, and more)
- Tennis, golf, and combat sports
Beyond sports, Underdog has also added non-sports categories such as politics, economics, entertainment/culture, crypto prices, and even climate events like hurricane landfalls, a broader spread than Novig's sports-only focus.
Availability
Underdog Predict has scaled quickly. It launched in 16 states in September 2025 and had expanded to roughly 28-35 states plus Washington, D.C. by mid-2026, with particular emphasis on states where traditional sports betting remains illegal, such as California and Texas.
Customer Support
Underdog offers in-app live chat and email support, along with a help center covering account, payment, and trading questions. Responsible-gaming tools include deposit and trading limits, timeouts, and account closure requests, alongside standard problem-gambling helpline signposting (1-800-GAMBLER, 1-800-MY-RESET, and state-specific lines like NY's HOPEline).
Underdog vs. Novig: Which Is Better?
Both platforms let users trade Yes/No sports contracts without a traditional bookmaker's built-in edge, but they take different approaches. Novig is a pure-play sports trading platform with a tighter, sports-only market list and its own CFTC-regulated platform dedicated entirely to sports trading. Underdog has a broader range, layering prediction markets ontop of its DFS platform and has markets that reach into politics, economics, and culture.
Traders who want a focused, sports-only trading experience may prefer Novig's simplicity. Those who want one app for fantasy contests, sports trading, and a wider range of prediction markets along with a wider US reach might prefer Underdog's all-in-one approach.
Final Verdict: Underdog Predict
Underdog is a fast-growing trading platform with a wide reach and simple design. Their welcome bonus is generous and the range of markets you can trade on is very enticing.
Combined with its existing scale in daily fantasy sports and a market list that now stretches well past sports, Underdog Predict is a strong option both for players looking for a an alternative prediction market platform.
