The 4 Truths and Fee Traps Behind Polymarket's LP Market Making Incentives
Polymarket, a prediction market platform, has recently shifted its focus to incentivizing liquidity providers (LPs) to address its core issue of low liquidity. While most markets remain free, it now charges a taker fee on specific markets like crypto price movements and select sports events. This fee, highest near 50% probability, funds new LP reward programs.
There are two primary reward systems: one pays LPs when their limit orders are executed (maker rewards), and another rewards simply for placing orders within a set spread to provide liquidity, even if they don't get filled. A third mechanism allows anyone to sponsor additional incentives for specific markets.
A positive view argues this structure values genuine liquidity over mere trading volume, making fees earned and rewards received a potential key, anti-sybil metric for a future POLY token airdrop. It rewards users who improve market depth and stability.
A contrasting, negative view claims the LP program is a "trap." Critics argue that professional market makers avoid it due to insider trading risks and that most LPs are actually losing money due to hidden "LP wear and tear" (impermanent loss), only participating based on speculation of a valuable airdrop. They warn that if Polymarket expands fees to fund these unsustainable rewards, it could lose its competitive edge of zero fees and better odds compared to traditional sportsbooks. Proposed solutions include a fixed fee only on profits, using a native POLY pool for liquidity, or charging for premium products like parlays instead of core markets.
