On September 19, River, the first BuildKey TGE on Binance Wallet, garnered roughly $100 million in BNB deposits within two hours, setting a new fundraising record for Binance Wallet IDOs. Early trading pushed the $RIVER token from $0.011 to $0.09 in seven minutes—an 800% intraday increase—while pre-market price caps imposed by Aspecta limited order fills, shifting some demand to alternate pre-market venues. At 23:00 Singapore Time on September 20, Bitget launched $RIVER pre-market trading; volume exceeded $1 million in 12 hours with daily volume projected near $3 million, and the quoted pre-market price reached approximately $3.80, about a 7,600% rise over the Binance Wallet IDO price. Historical Bitget pre-market benchmarks (WLFI, SAHARA, SIGN) averaged $200k–$600k daily, highlighting elevated market interest in the Binance Wallet model.
