About the product
What MarketBall is — and what it isn't.
MarketBall is a fantasy sports analytics and information platform. MarketBall analyzes prediction-market data alongside traditional fantasy football data to produce rankings, player analysis, market signals and editorial insights.
MarketBall does not accept wagers, facilitate betting, operate paid fantasy contests, offer monetary or material prizes, hold customer funds for wagering, or allow users to purchase or trade prediction-market contracts.
What customers pay for
MarketBall Free is a permanently free account tier. MarketBall Pro is a paid subscription that provides access to premium fantasy football analytics and information — full rankings, player analysis, market-derived insights, movement history and premium content. Nothing else is sold on MarketBall.
What is MarketBall?
MarketBall is a fantasy sports analytics and information platform. MarketRank™ starts with expert fantasy consensus and adjusts the rankings based on what prediction markets are telling us — plus player analysis, market signals and editorial insights in The Pulse.
What is MarketRank™?
MarketRank™ starts with expert fantasy consensus as its baseline. MarketBall then analyzes relevant prediction markets for each player, weighing signals based on their relevance, market depth, breadth and confidence. When credible market evidence differs from consensus, MarketRank adjusts the player up or down accordingly. The result is a market-adjusted fantasy ranking designed to show where prediction markets may be seeing something the traditional rankings aren't. Market Edge (Expert Rank − MarketRank) shows how far each player moved off consensus.
Can I bet or trade on MarketBall?
No. MarketBall is a fantasy sports analytics and information platform. We analyze prediction-market data to help identify where market expectations differ from traditional fantasy rankings and ADP. MarketBall does not accept bets, facilitate wagering, or allow users to buy or sell prediction-market contracts.
Does MarketBall offer paid fantasy contests or prizes?
No. MarketBall does not operate paid-entry fantasy contests or award monetary or material prizes. Paid subscriptions provide access to MarketBall's analytics, rankings, insights and content.
Does MarketBall hold funds for wagering or trading?
No. The only money MarketBall ever collects is a subscription fee for access to the analytics product, handled by our payment provider. We do not hold customer balances, deposits or trading accounts of any kind.
Why does MarketBall show prediction-market data then?
Because prediction-market pricing is a useful, publicly available information source. When people put money behind a forecast, the resulting price is a data point we can read, normalize and compare against fantasy expert consensus. We analyze that data — we do not provide the market or take part in it.
What exactly am I paying for with MarketBall Pro?
Subscription access to fantasy football analytics and information: full ROS and Weekly MarketRank™, Start/Sit and Trade Value analysis, Buy Low / Sell High and waiver insights, advanced Market Movers, deeper player pages and historical movement data. You can compare plans on the pricing page.
How do billing, cancellation and refunds work?
Monthly and annual plans renew automatically until cancelled; the NFL Season Pass is a one-time purchase and does not renew. Cancelling stops future renewals and you keep access through the end of the period you already paid for — we do not prorate unused time. Subscription payments are generally non-refundable once charged, but if you were charged in error or think there are exceptional circumstances, email support and we will review it. Self-service billing management is not live yet, so cancellations are handled by our support team. Full details are in the Refund & Cancellation Policy.
Are MarketBall rankings guaranteed to be more accurate than experts?
No. MarketRank™ layers a different kind of evidence on top of consensus, not a guaranteed better one. Prediction markets can be thin, slow to react to news, or simply wrong. Nothing on MarketBall is a promise of fantasy results, winnings or financial outcomes — treat it as one more input alongside your own research.
Is MarketBall affiliated with Polymarket or Kalshi?
No. MarketBall is not affiliated with, sponsored by, or endorsed by Polymarket or Kalshi. We read publicly available market data through their public APIs for analysis only.
