A market's price mixes the sharpest wallets with everybody else. Polkyo splits them apart, so you can see when the money with a record leans one way and the crowd the other, and check on resolved markets how often that paid.
- Holders, not headlines. Every figure comes from positions on the chain.
- Scored at entry. A wallet's record counts as it was when it bought, never with hindsight.
- Checked against outcomes. Every signal is graded on markets that already resolved, after fees.
