Polymarket primarily generates revenue through a combination of transaction fees, market creation fees, and liquidity incentives. When users trade shares in prediction markets, a small transaction fee is typically charged. Additionally, creators of new prediction markets may be required to pay a creation fee. To encourage active trading and maintain market liquidity, Polymarket may offer incentives to market makers and liquidity providers. By strategically balancing these revenue streams, Polymarket incentivizes user engagement while ensuring its own financial sustainability.
