Polymarket announced a new program to stabilize some of its long-running markets, paying out up to 4% annualized for selected positions. The platform pays out the highest rewards among prediction market apps.  Polymarket has added another incentive to ensure the stability of some long-term markets. A 4% annualized interest rate will accrue to selected positions for long-term holding. This approach will assure clearer crowdsourcing and more stability as Polymarket traders will be incentivized to remain in those markets for as long as possible.
