Crypto 5min + 15min Up/Down has become a key trading market on Predict Fun. Over the past month, the daily trading volume in the 5min + 15min market has grown from less than $2 million to nearly $4 million, achieving a doubling in growth. Based on the number of transactions, the 5min + 15min market now accounts for 60%-80% of the platform's trades and contributes approximately $60,000-$80,000 in daily fee revenue. As trading volume hits new highs, Predict Fun has launched a timely 25% Maker Rebate to further incentivize market-making and enhance order book depth. Makers not only enjoy 0 fees but also receive 25% of the Taker fees as rebates, automatically settled in USDT. This model aligns with the current trend in major prediction markets to boost liquidity through Maker Rebates. The high trading density of short-cycle Up/Down markets has already been validated on Polymarket, and Predict Fun now offers lower trading costs and more aggressive Maker incentives. Let’s see if the Maker Rebate can further deepen the order book and optimize the trading experience.
