PumpFun has re-emerged as the dominant launchpad for Solana-based memecoins, handling 89.6% of recorded daily trading volume on 17 Aug., according to market-tracking data. The platform’s resurgence follows the abrupt collapse of rival LetsBonkFun, which had briefly seized the lead earlier in the week. The shake-up has reordered a market that remains highly fluid. Newcomer Heaven ranked a distant but notable second after its debut weekend, while Bags, Moonshot and BonkFun accounted for 5.9%, 2.3% and 1.7% of volume, respectively. The rapid turnover underscores the volatility of Solana’s retail-driven token-launch niche, where user loyalty can shift within days.
