Markets where the crowd is right but underconfident. We only flag picks with 80%+ win probability and 20%+ upside. Most markets don't qualify. When they do, the math is in your favor before you place the trade.
Markets priced materially wrong. We quantify the edge — typically 8 to 25 percentage points off — cross-reference with live news and historical calibration data, and flag the ones worth trading. Three to eight a week when they exist. Zero when they don't.
Polymarket and Kalshi prices are set by the crowd. The crowd is well-calibrated on average but systematically wrong in predictable ways — overconfident in high-probability events, underconfident in low-liquidity markets, and slow to update on breaking news. WhenWin quantifies those gaps.
Every market we scan gets a probability estimate built from historical calibration data across 130,000+ resolved markets. When our estimate diverges from the market price by 8 or more points, the pick gets flagged for analyst review. Less than 5% of markets make it through.
What is a prediction market? A prediction market is a contract that pays $1 if an event happens and $0 if it doesn't. You buy YES shares if you think the event will happen, NO shares if you don't. Polymarket and Kalshi are the two main US-accessible prediction market exchanges.
How is WhenWin different from just using Polymarket? Polymarket gives you the market. WhenWin tells you which side has the edge. We scan every open contract, estimate the true probability, and flag the ones where the current price doesn't match the evidence.
Is this guaranteed to make money? No. We show every prediction we make, wins and losses. You will lose some bets. The edge is statistical — it plays out over many trades, not every individual one.
How do I get started? Start your free 7-day trial, fund a Polymarket or Kalshi account, and check the dashboard for current picks.
How often are new picks added? WinWhen keeps 10-20 high-probability picks running at all times. EdgeWin adds 3-8 new mispriced markets per week when opportunities exist.
