BisonFi led Solana DEX trading volume for the second consecutive week, ending Humidisi's months-long dominance. BisonFi now accounts for over 34% of daily trading volume on Prop AMMs, while Humidisi's share has dropped from over 68% a month ago to around 36%. Although Prop AMMs (like BisonFi and Humidisi) have significantly lower liquidity than traditional DEXs, their efficient funding strategies still allow them to dominate the majority of routed trades on the Jupiter platform, intensifying market competition and narrowing spreads for traders.
