About
Upside is a community of sports bettors and DFS players who bet with math, not tips. Members use the tools at upside.tools to compare prices across 50+ sportsbooks, DFS apps and prediction markets, find positive expected value (+EV) bets, and check whether their bets beat the closing line.
What you'll find here:
- Guides for the +EV Sniper, the Optimizer for player props and game lines, Whale Watch, Steam Chaser, the arbitrage and low hold finder, and the odds screen.
- Member wins from PrizePicks, Underdog, DraftKings Pick6, Betr, Kalshi, Novig, ProphetX and the major sportsbooks, with the numbers that made each bet +EV.
- Promo codes and sign-up offers from our partners.
- Help from bettors who use the tools every day, plus free calculators for no-vig fair odds, parlays, Kelly bet sizing, EV, arbitrage and hedging.
Verify your email in #get-verified to unlock the full server. Diamond members also get the VIP channels and alerts.
Nothing here is a pick or a guarantee. Every bet carries risk and you decide what to play. You must be of legal age to bet where you live. If you or someone you know has a gambling problem, call 1-800-GAMBLER.
