Polymarket's liquidity provider fee is expected to be 0.2% of the trading volume, with the platform's LP revenue exceeding $20 million in the past year.

BlockBeats News, October 15th, Buzzing founder Luke (@DeFiGuyLuke) revealed to BlockBeats two months ago: "The market maker on Polymarket should have made at least $20 million in the past year."

"Now, after a few months, we haven't collected the data yet, but it's definitely more. In terms of revenue model, based on market experience, a relatively conservative expectation is: a thousandth of the transaction volume, which is 0.2%."

BlockBeats' original article "People Who Quietly Made a Fortune on Arbitrage on Polymarket" revealed that if you provide liquidity in a market and the monthly trading volume is $1 million (including the trades you capture on both the buy and sell sides), then your expected profit is approximately: $1 million × 0.2% = $2000. This return rate may not seem high, but the key is that it is a relatively stable income, unlike speculative trading with large ups and downs.

Moreover, if you scale up to increase your earnings, then 10 markets would be $20,000, and 100 markets would be $200,000. If you add platform LP rewards and annualized holding, the actual returns will be higher, "but the main income is still the spread of market-making and the rewards given by Polymarket, these two parts".
