Bitcoin Spot ETF Experiences $51 Million Outflow, Ending Seven-Day Inflow Trend Amid Continued Decline in ETH

Bitcoin spot exchange-traded funds (ETFs) in the United States experienced their first notable outflow in over a week, with $51.28 million exiting the market on September 17, as reported by SoSoValue.

This downturn followed seven consecutive days of inflows that had generated optimism among institutional investors. The decline occurred just one day after U.S. Bitcoin ETFs recorded $292.27 million in net inflows on September 16.

Bitcoin Spot ETF Loses Momentum While Ethereum Funds Struggle With Persistent Outflows

The abrupt change indicates swift repositioning among major issuers. Fidelity’s FBTC faced the largest impact, recording $116.03 million in daily outflows, despite a historical net inflow of $12.56 billion.

Grayscale’s leading GBTC also experienced significant withdrawals, totaling $62.64 million, while Ark and 21Shares’ ARKB saw a reduction of $32.29 million. Smaller decreases were noted at Bitwise’s BITB, which lost $12.58 million.

However, not all funds experienced redemptions. BlackRock’s iShares Bitcoin Trust (IBIT) continued to draw in capital, securing $149.73 million on that day.

Grayscale’s lower-fee Bitcoin Mini Trust ($BTC) also recorded $22.54 million in inflows, bringing its lifetime total to $1.84 billion.

The net outflows resulted in total assets under management for Bitcoin spot ETFs reaching $152.45 billion, which represents 6.62% of Bitcoin’s market capitalization.

Cumulative net inflows across all products since their inception stand at $57.33 billion. Prices trended downward alongside the shift in flows, with many ETFs concluding the day with a decline of just over 1%.

Meanwhile, Ethereum ETFs continue to face challenges. On September 17, Ether products experienced $1.89 million in net outflows, extending a series of withdrawals that have persisted since early September.

Fidelity’s FETH was the largest loser, with $29.19 million in redemptions. Bitwise’s ETHW also saw $9.67 million exit the fund.

Inflows at BlackRock’s ETHA, which added $25.86 million, along with smaller gains at Grayscale’s offerings, were insufficient to counteract the overall weakness.

Total assets under management for Ether ETFs now amount to $29.72 billion, or 5.47% of Ethereum’s market capitalization. Cumulative inflows are reported at $13.66 billion.

The statistics follow a period of significant selling earlier this month, during which Ether ETFs lost over $1 billion across six consecutive sessions, including a $446.7 million single-day withdrawal on September 9.

In contrast, Bitcoin ETFs have demonstrated greater resilience. Earlier in September, funds accumulated more than $1.7 billion in inflows over four days, reversing the downturn from late August when Bitcoin ETFs recorded their first weekly outflows since June.

Ether funds continue to experience asset losses after a brief recovery mid-month, raising concerns regarding institutional confidence in Ethereum compared to Bitcoin.

SEC Approves New Listing Standards, Paving Way for More Crypto Spot ETFs

The ETF market has witnessed renewed interest from institutional investors. A new wave of cryptocurrency ETF applications has been submitted to the U.S. Securities and Exchange Commission (SEC), reflecting the industry’s efforts to expand beyond traditional Bitcoin and Ether products.

On Tuesday, five applications were filed, including Bitwise’s proposed spot Avalanche ETF and Tuttle’s “Income Blast” funds targeting Bonk, Litecoin, and Sui.

Defiance also submitted applications for ETFs based on Bitcoin and Ethereum basis trades, while T-Rex filed for a leveraged 2x Orbs ETF.

ETF Institute co-founder Nate Geraci indicated that the industry should prepare for “what’s coming over the next few months,” as the number of active applications surpasses 92, with many approaching autumn deadlines.

The filings coincide with REX-Osprey’s plans to launch XRP and Dogecoin ETFs on Thursday through the expedited 40 Act structure, which circumvents traditional SEC approval delays.

Momentum increased further on Wednesday when the SEC approved new listing regulations for major exchanges, including Nasdaq, Cboe BZX, and NYSE Arca.

This decision permits generic listing standards for commodity-based trust shares, paving the way for spot ETFs linked to a broader array of cryptocurrencies.

Bloomberg analyst James Seyffart characterized the move as the “crypto ETP framework we’ve been waiting for,” suggesting that Solana and XRP could be among the first to benefit.

In a separate development, the regulator approved Grayscale’s Digital Large Cap Fund, the first multi-asset crypto ETP in the U.S., offering investors exposure to Bitcoin, Ether, XRP, Solana, and Cardano.

Crypto Steadies as Fed Trims Rates 25 Bps, Bitcoin Eyes $118K Resistance

Bitcoin maintained a position above $117,000 on Thursday following the Federal Reserve’s first interest rate cut since December, reducing the federal funds rate by 25 basis points to a range of 4.00%–4.25%.

The cryptocurrency was last seen trading at $117,173, reflecting a 1% increase over 24 hours and a 5.7% rise over the past two weeks. Ethereum followed suit with stronger momentum, rising 1.8% on the day to $4,568, extending its gains to 6.2% over 30 days.

The Fed attributed its decision to weaker job growth and a less favorable economic outlook, noting that 911,000 fewer jobs were created in the past year than previously reported.

Inflation remains at 2.9%, above the bank’s 2% target. Chair Jerome Powell stated that future cuts would depend on economic data, while President Donald Trump has advocated for more substantial reductions.

Market reactions were swift. Over $105 million in crypto positions were liquidated within an hour of Powell’s comments, with long positions being the most affected.

The global crypto market cap briefly declined by 0.9% to $4.08 trillion, while Bitcoin fell to $115,089 before rebounding.

On-chain data indicates a reduction in sell pressure. Bitcoin exchange inflows have dropped to a yearly low, with the 7-day moving average decreasing to 25,000 BTC, down from 51,000 in July.

Average BTC deposits have halved since mid-summer. Ethereum exhibited similar patterns, with inflows declining to a two-month low of 783,000 ETH.

Traders are now concentrating on the $118,000 resistance level. Analysts suggest that a breakthrough could lead to a retest of Bitcoin’s record high near $124,000.
