What liquidity rewards are
Polymarket and Kalshi pay you to keep their order books tight. You post resting limit orders near a market’s midpoint, and you earn a share of a daily reward pool for leaving them there — whether or not anyone ever fills them. You are not being paid to predict the outcome. You are being paid to be the counterparty other traders can trade against.
It is a genuinely different activity from betting, and it carries genuinely different risks. Your resting orders get filled by whoever knows something you do not, precisely when the news breaks. An adverse fill you have to hold to resolution can cost more than months of rewards. This is not passive yield, and it is not free money.

What the LP Score is built from
Hundreds of markets are reward-eligible at any moment, and most of them are not worth your capital. The LP Score ranks them on the five things that actually decide whether a market is worth providing liquidity in.
Daily reward pool
How much the market pays out per day. Polymarket publishes an exact figure. Kalshi runs a liquidity-incentive program but does not publish per-market pools, so its markets are scored on book health and shown as eligible — verify the pool on Kalshi itself.
Competition
The pool is split proportionally, so the headline number is what everyone shares, not what you earn. A pool that looks generous is often generous because it is already crowded. Competition infers how contested a pool is from trading volume relative to its size — a quiet pool with a smaller number frequently pays better per dollar staked.
Price band
Markets nearer the middle let you quote both sides without accumulating brutal one-sided inventory. At the extremes, fills leave you holding a position that can lose far more than the rewards pay. On Polymarket, single-sided orders score nothing at all once the midpoint leaves the 10¢–90¢ band.
Spread health
A book that is already tight leaves little room to earn. A book that is wildly wide is usually wide for a reason — volatility, or nobody willing to stand in front of it. Neither extreme is where you want to be.
Time to resolution
Long-dated, low-catalyst markets move slowly, which means fewer adverse fills and less constant re-posting. Short-dated markets ask you to babysit orders against news you cannot see coming.
What this scanner will not tell you
It will not tell you exactly what you will earn. Polymarket does not publish total in-band LP liquidity for a market, which means no tool — free or paid — can know your precise share in advance. Anyone promising a guaranteed APR is hiding an assumption. Predacle estimates a conservative, typical and optimistic range instead, and tells you when a pool looks contested.
Predacle is a research tool. It does not hold funds, place orders, or trade on your behalf, and you should never hand any site your wallet’s private key to “automate” LP rewards. Always open the live order book on the platform before committing capital — a book moves faster than any aggregator refreshes. Access to both programs is region-restricted. Not financial advice.
