According to a study on the prediction market platform Polymarket, of the $13.76 billion transactions they analyzed, about 3% of the accounts were identified as “skilled traders” with a continuous trading advantage, and this group of accounts received about 27% of the total profit. These traders mainly trade by digesting public news more quickly, using inconsistent pricing between related contracts to arbitrage, and taking advantage of other participants' behavioral biases. But as more professional players chase the same opportunities, these advantages will be further compressed.
