Decentralized prediction market platform Polymarket has announced a major dual-strategy update for 2025, introducing a new tiered referral program and a sweeping shift to a dynamic, probability-based fee structure. The changes, announced by Senior Intern Mustafa on social media platform X on March 25, 2025, are set to take effect on March 30, 2025.
The new referral program is designed to drive user acquisition through a multi-level marketing-style reward system. Users can earn 30% of the platform’s revenue generated by their direct referrals, and a further 10% from the revenue of indirect referrals. The announcement also hinted at unspecified "future rewards" for active participants, potentially including airdrops or other incentives, aligning user growth with the platform's long-term health.
Concurrently, Polymarket is fundamentally changing its fee model. Moving away from a flat rate, the platform will implement a dynamic fee structure where the cost to trade varies by market. Fees will increase as the probability of a specific outcome approaches 50%, the point of maximum uncertainty and typically highest liquidity. Conversely, markets with lopsided probabilities (e.g., 90% Yes / 10% No) will carry lower fees. This model aims to optimize revenue from the most active speculative trades while potentially encouraging activity in niche markets.
In a related structural shift reported for 2026, Polymarket is expanding this dynamic taker-fee model to eight additional high-volume market categories, including Politics, Finance, and Economics, starting March 30, 2026. The fees, denominated in USDC, are not retained as profit but are used to fund a Maker Rebates Program, redistributing capital to liquidity providers to ensure tighter spreads and deeper order books. This expansion follows a successful pilot in January 2026 on 15-minute cryptocurrency markets, which was introduced to curb latency arbitrage by high-frequency trading bots.
The platform has explicitly noted a continued carve-out, allowing geopolitical and global event markets to remain fee-free. For the newly fee-bearing Politics category, market makers will receive a 25% rebate from collected fees, distributed daily.
