Fantasy League Economy turns your Sleeper fantasy football league into a live stock market. Every team becomes a publicly traded stock that rises and falls on real league performance - wins, losses, blowouts, lineup decisions, market trade impact mechanics. Buy shares in the team you think is undervalued. Short the team about to collapse or just to pressure down your buddies share price. Watch your portfolio compound across the season.
STOCK MARKET
Every team in your league has a share price driven by real performance. Buy low when a sleeper hits. Short the team coming off a fluke win. Price impact caps prevent runaway whales. Live charts, P&L, all-time history, etc.
SPORTSBOOK
Pick winners of every matchup in your league each week. Lock-time enforced by real NFL kickoff. Win BrainyBucks (BBU) for correct picks. Weekly SportsBook leaderboard to see who the most accurate predictor is.
BOUNTIES
Put a target on rival teams. If your bounty hits - the target team loses - the winning team claims your bounty price. Place bounties on your worst enemy in the league.
