These marine mammals live in oceans around the world, from warm tropical waters to the cold seas surrounding the poles.

A trader in Canada wants to place a prediction on U.S. election outcomes. A financial analyst in Singapore seeks to forecast oil prices. A researcher in the European Union is interested in testing a geopolitical hypothesis through market signals.

A trader depositing $50,000 into a decentralized prediction market needs to know that the platform will not lose the funds to a contract vulnerability, that settlements will not be gamed by insiders, and that the blockchain will execute trades as intended. Polymarket, operating on Polygon Layer-2 and handling tens of millions in daily volume across thousands of markets, depends entirely on smart contract logic and

A trader executes fifty prediction market trades over six months on Polymarket, closing some positions at a loss and reopening similar bets days later as market conditions shift. By year-end, the net result is a modest gain, but the trader has not recorded which trades closed at losses or how they relate to subsequent positions.
