About Alex

Alex Copert writes PredictReport's platform reviews and trading guides. The beat is the machinery of prediction markets: how Polymarket, Kalshi and the newer venues match orders and settle contracts, what their fees add up to at realistic prices, and how a price on one venue relates to the same question on another.

The reviews compare platforms on the things that decide whether a trade is worth making — fees, order-book depth, deposit and withdrawal friction, regulation — rather than on marketing claims. The trading guides go a level deeper, into limit orders, liquidity, hedging, market making and arbitrage, with worked numbers throughout.
