The probability of a Trump victory has now fallen to 62 per cent, from a previous high of 67 per cent, according to Polymarket, and some observers believe the rise reflects hedging positions among traders, who are hedging their bets on a Harris victory, following earlier reports of "Trump voting irregularities". More researchers point out that if traders can access Robinhood Securities and Polymarket at the same time, then there is a good arbitrage opportunity. Users can bet on Trump's election on Robinhood and Harris on Polymarket, and whoever wins will profit (Harris's win rate on Robinhood Securities is higher than that on Polymarket).
