Phemex has introduced a new prediction market trading layer, kicking off with a four-week "Prediction Championship". The campaign includes weekly profit and loss (PnL) and return on investment (ROI) leaderboards to reward top traders. Additionally, a first-trade rebate program is available for the first 500 eligible users, covering their initial trade. The platform integrates Polymarket infrastructure, allowing users to trade real-world event probabilities directly from centralized accounts using USDT or USDC. This initiative aims to enhance user engagement by offering innovative trading opportunities and incentives.
