MarketBall is a fantasy sports analytics and information service. We analyze publicly available prediction-market data to produce fantasy football rankings, player analysis and editorial insights. MarketBall is not a sportsbook, an exchange, or a fantasy contest operator: we do not accept wagers, hold customer funds for wagering, let users buy or sell prediction-market contracts, or award monetary or material prizes. Subscriptions pay for access to analytics and content only. Nothing here is gambling, investment or financial advice.
Not affiliated with, or endorsed by, Polymarket or Kalshi. Market data via the Polymarket Gamma API and the Kalshi API; player data via Sleeper. Support: marketballsupport@gmail.com
