About wagerup
What is WagerUp?
WagerUp is a sports prediction market platform that aggregates odds from multiple exchanges, sportsbooks, and market makers into a single trading interface. Instead of locking users into one venue, it pulls live prices from connected sources, including Kalshi and Polymarket, and routes each trade to the best available price automatically.
The platform covers all major US leagues, NFL, NBA, MLB, and NHL, along with global soccer competitions, combat sports, and esports. Users can trade moneylines, spreads, and totals across these markets from one place.
The fee model sets WagerUp apart from legacy sportsbooks. It charges a flat 1.9% only on winning trades. A user who loses a bet pays nothing. DraftKings, FanDuel, and BetMGM typically embed a 10 to 20% vig into every bet, win or lose. On a $100 winning bet, WagerUp returns $98.10 to the user. The same bet at a major sportsbook might return $80 to $90.
WagerUp launched in 2026. Its network of syndicate partners executed over $1.2 billion in volume in 2025, giving the platform a foundation of real trading activity before its public release.
Who uses it?
WagerUp targets sports traders who care about price, not casual bettors who place a weekly wager for fun. The platform is built for people who compare odds across books, track their profit and loss over time, and treat sports markets the way stock traders treat equities.
Crypto-native users already familiar with Polymarket or Kalshi make up another core group. These users understand prediction market mechanics and want access to sports events specifically. WagerUp connects that existing behavior to a broader range of sports markets in one portfolio view.
High-stakes bettors and syndicate members are also a natural fit. The platform's liquidity aggregation gives larger traders access to deeper order books than any single exchange can provide on its own, which matters when someone wants to place a meaningful position without moving the market.
WagerUp's team has direct relationships across professional sports and high-stakes betting communities, so early adoption has come through those networks rather than mass advertising.
How it works
A user opens WagerUp and sees live markets across every supported league, with real-time odds pulled from all connected venues at once. The aggregated order book shows the combined depth from Kalshi, Polymarket, and other connected sources side by side.
When a user selects a market and places a trade, WagerUp's smart order router scans every connected exchange and market maker at that moment. It finds the best available price and executes the trade automatically. The user does not have to check multiple sites or accounts to find a better line.
After execution, the trade appears in the user's unified portfolio alongside any other active positions. The portfolio tracks profit and loss across every venue in real time, so a user with trades on several markets sees their full picture in one view.
Settlement is straightforward. If the trade wins, WagerUp takes a 1.9% fee from the return. If it loses, there is no fee. There are no hidden spreads and no subscription costs.
The regulatory environment has shifted in WagerUp's favor. The CFTC withdrew its proposed ban on sports prediction markets in February 2026, and the NFL has signaled openness to this category. That change removes one of the main legal uncertainties that had slowed prediction market growth in the United States.
Key Features
Pros & Cons
-
Fee only on winsYou pay a 1.9% fee when you win, and nothing when you lose, compared to DraftKings and FanDuel which charge a 10-20% vig on every bet.
-
Best price found automaticallyThe smart order router scans every exchange, sportsbook, and market maker at once, so you get the best available price without checking each venue yourself.
-
All positions in one viewYour active trades and P&L across every connected venue show up in a single portfolio, so you are not logging into separate accounts to see where you stand.
-
Aggregated order book depthLiquidity pulls from every connected venue at the same time, which gives you more depth than any single exchange can offer on its own.
-
Not yet publicly launchedThe platform is scheduled to launch in 2026, so you cannot open an account or test any of the trading features today.
-
Fee structure rewards winners onlyPaying nothing on losses sounds appealing, but a 1.9% fee on every winning trade adds up fast for high-volume traders who run thin margins.
-
Dependent on connected venuesThe quality of price aggregation and order book depth depends entirely on how many exchanges and sportsbooks are connected, and that network is unproven at this stage.
-
Aimed at serious tradersThe platform is built around live trading, order books, and P&L tracking, which means casual bettors who want a simple interface will likely find it overwhelming.
