With the rapid rise of alternative betting models in the U.S., sweepstakes sportsbooks have carved out a niche market for players looking for a legal, innovative, and engaging way to enjoy sports wagering. Instead of traditional deposits and withdrawals, these platforms operate under sweepstakes regulations, allowing users to play with virtual currencies that can be redeemed for cash or prizes.
Our rankings of the top sweepstakes sportsbooks are based on user experience, promotions, unique features, and overall reputation. The industry is constantly evolving, and we regularly update this list to reflect the latest developments. Here are our top five sweepstakes sportsbooks in 2025.

#2 – ProphetX
ProphetX stands as a true pioneer in the sweepstakes sportsbook space, having originally launched as the first peer-to-peer sports betting exchange in the United States back in August 2022. The company’s innovative transition from a regulated exchange in New Jersey to a nationwide sweepstakes model in mid-2024 opened the doors to over 40 states, making the ProphetX app accessible to a much broader audience and setting the standard for others to follow.
What makes ProphetX unique is its peer-to-peer marketplace, which allows users to set their own odds or take advantage of market pricing by betting against other players, rather than the house. This approach consistently delivers some of the best-priced odds in U.S. sweepstakes betting, with additional flexibility and transparency for both new and experienced users. ProphetX was also one of the first to integrate social competition, leaderboards, and instant buy-in contests across multiple sports
As of October 1, 2025, ProphetX lowered its commission structure industry-wide from 3% to just 1% on all markets – a major reduction that secures better long-term value for players

#1 – Novig
Novig has rapidly emerged as the top sweepstakes sportsbook thanks to its groundbreaking no-fee (no vig) model that sets it apart from nearly every other platform. Unlike traditional sportsbooks that charge a commission on every bet, Novig operates as a peer-to-peer exchange where players bet directly against one another, resulting in better odds and more value for users.
One of Novig’s greatest strengths is its unique rewards program. Players receive an immediate welcome bonus of 1,000 Novig Coins plus 5 Novig Cash upon sign-up, with no deposit required. Additionally, Novig offers progressive daily login bonuses, referral rewards, and frequent promotions that enhance long-term engagement.
Novig stands out not just for its innovative mechanics but also for its remarkable growth, building a vibrant social community with active player leaderboards, custom odds creation, and real-time bet trading features that foster a dynamic peer-to-peer marketplace. With availability across most U.S. states (excluding a few), Novig combines innovation, transparency, and player-centric policies to lead the sweepstakes sports betting industry in 2025.

Factors in Grading Sweepstakes Sportsbooks
1. Prize Payouts
The most important factor is how quickly and reliably a platform processes prize redemptions. We only recommend sites with a strong track record of converting sweepstakes winnings into real-world rewards without delays.
2. Odds and Markets
Although formatted differently than traditional sportsbooks, odds variety still matters. Platforms that provide diverse markets—including props, futures, and niche sports—rank higher on our list.
3. User Experience
We place strong emphasis on the usability of both desktop and mobile apps. Sweepstakes sportsbooks must balance accessibility for beginners with advanced tools for more experienced players.
4. Promotions and Rewards
From daily bonuses to redeemable tokens, generous promotions add significant value for players. We highlight sportsbooks that reward both new and long-term users.
5. Innovation
Since this is still a young industry, innovation carries weight. We rank platforms higher when they bring new approaches, such as exchange-style trading or gamified challenges.
