Polymarket market makers are expected to earn 0.2% of trading volume, with market maker earnings exceeding $20 million over the past year.

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

"We haven't compiled the latest data after a few months, but it's definitely more. Specifically regarding the profit model, based on market experience, a relatively stable expectation is: 0.2% of the trading volume."

The original BlockBeats article "Those quietly profiting from arbitrage on Polymarket" disclosed that if you provide liquidity in a certain market and the monthly trading volume is $1 million (including both buy and sell orders you take), then your expected profit is approximately: $1 million × 0.2% = $2,000. This yield may not seem high, but the key is that it is relatively stable, unlike the volatility of speculative trading.

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