Spot Bitcoin and Ethereum ETFs add $2.6B over five days as BTC leads inflows

U.S.-listed spot Bitcoin and Ethereum ETFs pulled in about $2.6 billion in combined inflows over a recent five-day trading stretch, marking a record-breaking week and the strongest week since October, according to reporting from multiple outlets ^{[1] [2] [3]}.

The inflows were led by Bitcoin funds, which gathered roughly $1.92 billion (about 73% of the total), while Ethereum ETFs added about $697 million with positive flows across all five trading days. BlackRock’s products reportedly accounted for around 79% of Friday’s aggregate inflows ^{[2] [3]}.

Separately, one outlet reported that on Aug. 21 spot Bitcoin ETFs recorded $307 million in net inflows, extending a five-day streak, while spot Ethereum ETFs recorded $185 million in net inflows, also extending their five-day streak ^[4].

Overall, the cited reports attribute the recent performance to sustained net inflows into U.S. spot Bitcoin and Ethereum ETF products over the same multi-day period ^{[1] [3]}.
