Bitcoin, Ethereum and Solana exchange-traded funds appeared to experience a dramatic shift as of December 26 and that gives a very clear picture of institutional capacity to move sentiment on the crypto market.

According to recent data by LookOnChain, Bitcoin and Ethereum ETFs experienced significant weekly outflows, while Solana ETFs showed the opposite trend with consistent inflows. The difference brings out the evolving investor preferences as the market approaches the last days of the year.
Bitcoin ETFs Face Continued Weekly Pressure
Over the past 7 days the caution by investors towards the Bitcoin ETFs has been on a sharp rise especially after another day of small withdrawals towards the end of December.Totally, there were 309 BTC in net outflows in Bitcoin ETFs daily (approximately 26.9 million dollars). In the last seven days, the net outflows amounted to 7,015 BTC; it is about 610.43 million.However, there are still outflows of Bitcoin ETFs with the value totaling 1,300,790 BTC, worth approximately 113.19 billion. This shows that despite the reduced exposure of some of the investors, the exposure is generally high amongst the institutional holders.
BitTorrent BlackRock’s IBIT still leads Bitcoin with 772,584 BTC in management. Its fund reported no inflows or outflows per day but had an outflow of 4.742 BTC per week. The products of Grayscale had 214,516 BTC holdings with a weekly outflow of 775 BTC.
The FBTC of Fidelity reported a daily loss of 196 BTC and a weekly loss of 240 BTC. Bitwise and ARK 21Shares, among other funds, also reported stable outflows each week.
Ethereum ETFs Show Flat Daily Action but Weak Weekly Trend
Ethereum ETFs exhibited a similar trend, with their relatively calm daily performance mirroring their similarly calm weekly performance.
On the 26th of December, Ethereum ETFs had zero net inflows or outflows. However, the total outflows over the last seven days amounted to 34,679 ETH, valued at approximately 100.6 million.
Currently, Ethereum ETFs hold a total of 6,079,918 ETH, estimated to be worth 17.64 billion dollars. ETH BlackRock has the highest holding at 3,486,575 ETHA, though this amount has been outflowing by 41,415 ETFs per week.
Ethereum ETFs in Grayscale recorded a record of 13,360 ETH in weekly inflow, despite the majority of other funds recording lower movement. At the daily and weekly timeframes, Fidelity (FETH) did not change and indicated stable positioning.
The mixed flows indicate that rather than completely abandoning the asset class, Ethereum investors have become pickier and move their money between funds.
Solana ETFs Are Receiving the Most Attention
Unlike Bitcoin and Ethereum, Solana ETFs provided a strong positive indication.
And even though the flows were flat on a daily basis, Solana ETFs experienced an impressive 7-day net inflow of 169,556 SOL, equivalent to 20.69 million. The current shares are 7,813,822 SOL, which is worth approximately 953.29 million.
Several large issuers contributed to the weekly gains.
Bitwise’s BSOL added 32,408 SOL
The GSOL of Grayscale experienced inflows of 34,185 SOL.
The FSOL by Fidelity had the highest inflow of 76,872 SOL per week.
VanEck’s VSOL gained 26,092 SOL.
These inflows indicate that there is increased confidence in the Solana ecosystem, especially among investors seeking growth assets other than Bitcoin and Ethereum.
What the Diverging ETF Flows Mean for the Market
The outflow in Bitcoin and Ethereum ETFs and inflow in Solana ETFs shows a potential institutional strategy change.
Instead of fully withdrawing capital out of crypto, it appears that the investors are shifting their capital into assets with more perceived near-term momentum or ecosystem development. The most recent network activity of Solana and the spread of its use case could be behind these decisions.
Regarding the future market, the trend may promote the further diversification of the crypto ETFs and less dependency on Bitcoin and Ethereum. If Solana continues to receive stable inflows, it could become a strong institutional asset rather than a fringe asset.
Meanwhile, the fact that Bitcoin and Ethereum ETF holdings remain substantial means that confidence in the long perspective persists. While this may not be a pessimistic outlook, we can mitigate short-term outflows through portfolio rebalancing, year-end adjustments, or risk management.
In 2026, ETF flows will continue to be an important indicator of institutional sentiment. The trend of Solana still being active or capital moving back to Bitcoin and Ethereum will significantly determine the future trajectory of the crypto market.
