Bitcoin ETF Inflows Shrink to $5M as Ether Funds Shed $60M

A positive day that still shows a weak market

On October 15, U.S. spot bitcoin exchange-traded funds brought in $5.06 million of net new money. BlackRock's iShares Bitcoin Trust (IBIT) took in $16.79 million on its own, which means the other funds lost money overall.1 Grayscale's Bitcoin Mini Trust had $7.64 million in redemptions and Invesco's BTCO had $4.09 million. Trading across the funds came to $2.28 billion, and combined net assets ended the day at $105.71 billion.4

Ether funds lost $60.22 million on the same day. BlackRock's iShares Ethereum Trust (ETHA) accounted for $44.39 million of that, roughly three-quarters of the total.1 Grayscale's ETHE lost $18.28 million. Fidelity's FETH was the only one of the three to gain money, taking in $2.44 million.8 Taken together, bitcoin and ether funds had a net outflow of about $55.16 million.1 Across U.S. spot ETFs tied to 15 different crypto assets, the day's net outflow was about $89.4 million. Funds holding Solana, XRP, BNB, Zcash and Hyperliquid's token all lost money, while NEAR and Chainlink products took in small amounts.3

The best way to read October 15 is as a pause in the selling, not a return of demand. Most outlets reported the same flow figures, but they framed them differently. One described the bitcoin inflow as a sign of institutional interest and a move toward bitcoin and away from ether.2 Others called the gain small and fragile.4 One noted it was the smallest daily bitcoin ETF inflow of the month so far.6 The day-by-day figures support the more cautious reading.

October has been choppy

Bitcoin ETF flows have changed direction often this month. In the week of October 12, the funds lost $65.40 million on Monday, gained $175.62 million on Tuesday, lost $261.46 million on Wednesday and gained just $5 million on Thursday.4 The week before was worse. Bitcoin ETFs lost about $681 million from October 5 to 9, which ended a three-week run of inflows. Ether funds lost about $542 million in the same week, bringing the two-asset total to roughly $1.22 billion.20 The heaviest day was October 7, when about $485 million left the bitcoin funds, the most since late June.13

One tracker shows October running about $540 million negative through October 14. That follows inflows of roughly $2.6 billion in September and $3.5 billion in August.11 Over a longer window, though, bitcoin still looks strong. Its ETFs took in about $2.1 billion over the past 30 days, while ether ETFs lost about $360 million.3 So October so far looks more like a pullback after a large late-summer rally than a lasting exit.

Trackers don't agree on all the numbers. Reported cumulative bitcoin ETF inflows since January 2024 include $56.96 billion6, $57.22 billion18 and $57.68 billion12, depending on the provider and the date. Net asset figures also move with the bitcoin price. One compilation put assets at $111.09 billion on October 813, about $5 billion more than the October 15 figure. The differences are small compared with the overall trend. Still, single-day flow numbers are provisional and often get revised after issuers finalize their reports.11

Ether is the weakest major fund group

On the bitcoin-versus-ether question, the reporting is consistent. Ether funds briefly took in $24.84 million on October 13, ending a streak of about ten straight days of outflows.16 They then lost $129.51 million on October 14 and another $60.22 million on October 15. Over four sessions, ether ETFs lost about $250 million, almost twice as much as bitcoin funds lost over the same period.4 One report counted roughly $600 million of ether ETF outflows the week before.8

Ether's price went up even as money left. It rose about 3.5% to around $2,444 on October 15, while the funds were seeing redemptions.6 Spot ether ETFs still hold $15.29 billion, about 5.10% of ether's market value, and ETHA alone holds $8.31 billion.10 Fund-flow data also points to ether as the asset investors are cutting first. Perpetual futures funding rates for ether turned negative for parts of the October 5–9 week, while bitcoin's stayed near neutral. That pattern suggests traders were reducing ether exposure faster.19

Some see this as a temporary problem. Grayscale research head Zach Pandl has called Ethereum an underappreciated opportunity because stablecoins, tokenized deposits and real-world assets are moving onto blockchains.8 That may prove right over the long run. For now, ETF buyers are not acting on it.

Macro conditions are driving flows

There is broad agreement that economic conditions, not crypto-specific news, are behind October's swings. Reports on the early-October outflows cited high Treasury yields, a stronger dollar, inflation worries and general caution toward risky assets.1719 On October 15, one outlet blamed an unexpectedly hot U.S. producer price report for the altcoin ETF losses and pointed to the Federal Reserve's October 28 meeting as the next major event.6 The midterm elections on November 3 are another source of uncertainty for crypto policy.7

The reporting differs on how bad inflation is. One account, citing The Kobeissi Letter, said producer price inflation jumped to 6.3%.6 A separate piece described core inflation as sticky at 2.6%.23 These may be different measures, but readers should treat the more alarming figures carefully. The price action was calmer than the flows. Bitcoin dropped below $80,000 for about two hours on October 15 and then recovered to above $82,000.9

Bitcoin treasury companies face their own pressures

Publicly traded companies that hold bitcoin as a treasury asset are a second major source of demand alongside ETFs. They are also showing strain, for different reasons.

Strategy, the largest corporate bitcoin holder, bought only 250 BTC between October 5 and 11, its smallest purchase of 2026. In the same week it spent $192.4 million buying back its STRC preferred shares, nearly nine times what it spent on bitcoin.27 The company holds 848,250 BTC at an average cost of about $75,444 per coin. As of October 11 it also had a $4.88 billion USD Reserve and $640.5 million in cash.2527 Its year-to-date "BTC Yield" was negative 3.7% as of October 4. That metric measures bitcoin held per assumed share, so a negative figure means share dilution and financing costs are outpacing the company's purchases.21 Strategy reports third-quarter results on October 29.26

Other treasury firms are still buying aggressively. Strive bought 2,822 BTC in mid-October, bringing its total to 35,595 BTC and moving it past MARA into fourth place. It has also filed to raise $500 million through a new preferred share class to buy more bitcoin.23 Metaplanet sold 10,000 BTC and bought 11,000 back, a move reported as a way to demonstrate liquidity.29 Citigroup raised its Strategy price target to $240 and forecast $5 billion of net ETF inflows over the next twelve months.29

The biggest risk for the sector came from index provider MSCI. It has finalized rules that exclude companies built mainly around bitcoin holdings from its global equity indexes. Strategy and Metaplanet could be removed as early as November 30.28 Index funds would then have to sell those shares on a fixed schedule. That selling could narrow the premium to net asset value that lets these companies raise money cheaply.28 The companies would not have to sell any bitcoin. But together with Strategy's shift toward buybacks, the ruling makes treasury companies a less reliable source of buying than they were last year.

Regulators are acting without Congress

The regulatory picture is not causing the flow swings, but it matters over the longer term. The CLARITY Act, the market-structure bill, failed a Senate procedural vote 49–50 on September 15. It is now widely expected to need reintroduction in the next Congress.32 The agencies have moved ahead anyway. On October 1 the SEC proposed custody rules that would let state trust companies act as custodians and allow self-custody in some cases.31 Comments on the SEC's proposed Regulation Crypto Assets, which sets rules for token offerings, are due October 20.33 The CFTC published an advance notice of rulemaking on retail crypto markets, with comments due December 14.37

The custody proposal could eventually make it easier for investment advisers and funds to hold crypto, which would help the ETF business.31 However, rules written by agencies are easier for future commissions to change than laws passed by Congress.32

Outlook

The bitcoin ETF market is not collapsing. It is cooling off after a strong late summer and is sensitive to yields, inflation data and the Fed. Ether is weaker, with steady outflows even when its price rises. The treasury companies that helped support bitcoin demand now face index removal and expensive financing at the same time. The key dates are October 28 for the Fed and October 29 for Strategy's results. Until bitcoin ETFs put together several days of real inflows, small gains like October 15's are better read as a break in the selling than as a recovery.
