$986M Weekly Inflows Trigger Bitcoin ETF Boom and What Does it Mean?

In Bitcoin ETF news today, US-listed BTC ETFs pulled in $986.9M in net inflows for the week ending September 4, a +6.7% increase from the prior week, according to CoinGlass data.

Over the same five trading days, inflows into Ethereum, Solana, XRP, and Hyperliquid ETF products fell between 73% and 96%. The divergence matters because it reverses the script from the week before, when altcoin funds posted triple-digit percentage gains.

US spot $BTC ETFs just printed their biggest inflow day since January. On September 3, the funds pulled in roughly $731 million. BlackRock’s IBIT accounted for $454 million of that. And then the buying kept coming.
