Bitcoin and Ethereum ETFs recorded significant inflows on September 19, 2025, even as the broader crypto market declined sharply. Despite a $102 billion market-wide loss, institutional interest in crypto exposure remained firm through ETF channels.

Bitcoin ETFs now hold a combined 1,317,560 BTC, equivalent to approximately $152.84 billion in assets under management. Net inflows reached +1,205 BTC ($139.75 million) in the past 24 hours and +11,308 BTC ($1.31 billion) over the past 7 days.

Fidelity’s Wise Origin Bitcoin Fund led daily inflows with +828 BTC ($96.09 million), pushing its total holdings to 207,370 BTC ($24.05 billion). Other notable contributors included ARK 21Shares Bitcoin ETF with +213 BTC, Bitwise with +109 BTC, and VanEck with +175 BTC.

Grayscale Bitcoin Trust saw the largest daily outflow of -549 BTC, bringing its total to 177,389 BTC. However, BlackRock’s iShares Bitcoin Trust remained dominant, holding 764,993 BTC, supported by a strong +17,629 BTC weekly inflow.

Ethereum ETFs Outpace Bitcoin in Weekly Growth

Ethereum ETFs posted higher inflows than Bitcoin over the same 7-day period, highlighting growing interest in ETH-based products. Combined holdings reached 6,636,396 ETH, totaling about $29.86 billion in value.

Daily inflows into Ethereum ETFs stood at +41,150 ETH ($185.17 million), while weekly inflows totaled +195,993 ETH ($881.97 million). Fidelity’s Ethereum Fund led all ETH ETFs, adding +34,688 ETH ($156.1 million) in one day.

That brought its total to 817,134 ETH ($3.68 billion) under management. BlackRock’s iShares Ethereum Trust remained the largest ETH ETF, holding 3,802,294 ETH, after a +117,674 ETH weekly increase.

These flows suggest Ethereum is attracting increased institutional attention, possibly in anticipation of future developments or upgrades. The trend may indicate a diversification strategy among investors balancing Bitcoin and Ethereum exposure.

Market Pullback Highlights Fragility as Coinbase Reserves Climb

Despite ETF inflows, the crypto market saw broad-based losses, with Bitcoin dropping 1.30% and Ethereum falling 2.61% in 24 hours. Altcoins underperformed, with XRP down 3.53%, Solana 4.07%, and Dogecoin 6.06%.

Stablecoins such as USDT and USDC remained stable, offering liquidity during market stress. Notably, Avalanche and SMART defied the trend with modest gains of +2.54% and +2.24%, respectively.

Meanwhile, Coinbase reserves reached $112 billion in BTC, ETH, and stablecoins, the highest in four years, according to CryptoQuant. Historically, rising exchange reserves have signaled stronger liquidity and potential bullish momentum.

Although short-term sentiment remains cautious, the sustained ETF accumulation and rising exchange reserves reflect long-term institutional confidence. Investors appear to be preparing for eventual market recovery while navigating near-term volatility.
