Short answer: yes. Polymarket is the exchange where you trade. WhenWin is the analysis layer that tells you what to trade and which side has the edge. They do different things.
Polymarket is a decentralized prediction market exchange where you trade on the outcomes of real-world events. You buy YES shares or NO shares that pay out $1 if you're correct. Polymarket provides the market infrastructure — pricing, liquidity, and settlement — but no analysis or recommendations.
WhenWin scans every open Polymarket contract every 2 hours. We estimate the true probability using historical calibration data from 130,000+ resolved markets, cross-reference with live news, and flag markets where the current price is wrong by 8 or more percentage points.
The output is two things: WinWhen picks (high-probability markets where the crowd is right but the price undervalues the outcome) and EdgeWin picks (mispriced contracts where we have a quantified edge). Every pick is tracked publicly against the actual result.
Polymarket: trade execution, liquidity, market creation, settlement. No picks, no analysis, no track record.
WhenWin: market analysis, edge identification, pick recommendations, public track record, win probability estimates. No trading — you still execute on Polymarket.
Anyone who wants to know which Polymarket contracts are mispriced before placing a trade. If you're already on Polymarket and looking for an edge, WhenWin is the research layer you're missing.
Is WhenWin affiliated with Polymarket? No. WhenWin is an independent analysis tool. We scan Polymarket's public data and run our own models on top of it.
Do I need a Polymarket account to use WhenWin? You need a Polymarket or Kalshi account to actually place trades based on our picks. WhenWin tells you what to trade — you execute the trade on the exchange.
How is WhenWin's track record verified? Every pick is timestamped before the market resolves. Entry price, direction (YES or NO), and outcome are all logged. You can cross-reference any pick directly on Polymarket.
