Bitcoin ETFs Lead Crypto Inflows as BlackRock IBIT Tops $596M Weekly Demand

US spot Bitcoin ETFs kept pulling in serious capital last week, with BlackRock’s IBIT once again doing the heavy lifting while Ethereum, Solana, and XRP products also drew fresh money.

• Bitcoin ETFs led weekly crypto fund inflows with about $623 million.
• BlackRock IBIT dominated demand, accounting for roughly $596 million of that total.
• ETH, SOL, and XRP ETFs all posted inflows, but Bitcoin still ran the show.
• Regulation and surveillance remain major market forces, from the CLARITY Act to South Korea’s AI tax tools.

US spot Bitcoin ETFs recorded about $623 million in net inflows over the week, a reminder that the simplest way into crypto for many investors is still a fund that holds actual Bitcoin. That’s what a spot ETF is: a regulated product that buys and stores the underlying asset, rather than gambling on futures contracts and price derivatives. For institutions and cautious allocators, it’s the difference between “I own exposure” and “I’m pretending to own exposure.”

BlackRock’s iShares Bitcoin Trust, or IBIT, did most of the work with roughly $596 million in inflows. That pushes its cumulative net inflows to about $66.1 billion and reinforces IBIT’s position as the bellwether for institutional demand. The reason is pretty simple: brand trust, deep liquidity, and low friction matter. No amount of crypto Twitter victory laps changes the fact that big money tends to move toward products that are easy to trade, easy to explain, and cheap enough not to feel like a toll booth at every turn.

IBIT’s scale also creates a flywheel. More assets under management mean more liquidity, which attracts more allocators, which brings in more assets. That’s the kind of winner-takes-most dynamic that shows up in nearly every mature financial market. Bitcoin may be decentralized; ETF flows are not. In this game, size begets size.

ARK 21Shares Bitcoin ETF, or ARKB, added about $53.1 million, while Grayscale’s GBTC saw roughly $62.3 million in outflows. GBTC’s situation remains a cautionary tale for anyone who thinks being first is enough. It was the original institutional Bitcoin vehicle, but it lost the edge once cheaper, cleaner spot Bitcoin ETFs arrived. Legacy structure, higher costs, and weaker liquidity are a rough combo. The market did what markets do: it punished the expensive relic and rewarded the streamlined product.

Total net assets across US spot Bitcoin ETFs sat around $106.61 billion, equal to about 6.67% of Bitcoin’s market cap. That’s not a rounding error. A meaningful slice of BTC exposure now sits inside brokerage accounts, wealth platforms, and retirement-style wrappers instead of self-custody wallets. That is both a genuine adoption win and a reminder that “financialization” isn’t automatically a dirty word. Plenty of people want Bitcoin exposure without memorizing 24 words and praying they never misplace a backup like a sleep-deprived raccoon.

Ethereum ETFs were positive too, but less forceful. US spot Ethereum ETFs logged about $70.49 million in weekly inflows, led by BlackRock’s ETHA with roughly $100 million in inflows. Fidelity’s FETH, meanwhile, posted about $32.16 million in outflows. US spot Ethereum ETF net assets reached about $13.73 billion, or 4.94% of Ethereum’s market cap.

ETH’s ETF demand is real, but it still looks less decisive than Bitcoin’s. That doesn’t mean Ethereum lacks a role. It clearly does. It powers a huge share of decentralized finance, stablecoin activity, and smart-contract experimentation. But in ETF form, ETH is still fighting for the same kind of clean, one-line narrative Bitcoin has owned for years: digital scarcity, sound money, and hard-to-ignore brand recognition. Bitcoin is the default. Ethereum is the multifunctional platform. Markets generally understand the difference.

The newer spot products tied to altcoins also continued to attract capital, though on a much smaller scale. US spot Solana ETFs posted about $39.23 million in inflows, with Bitwise’s BSOL leading at roughly $36.39 million. Solana spot ETF net assets were estimated at about $987 million. US spot XRP ETFs drew about $34.21 million in inflows, with Canary’s XRPC bringing in around $13.54 million. XRP spot ETF net assets were estimated at about $1.12 billion.

These numbers matter because they show that BTC is no longer the only ETF game in town. Still, let’s not pretend the market has become evenly distributed. Bitcoin remains the institutional favorite, Ethereum has second-mover strength, and Solana and XRP are building smaller footholds. That’s not a knock on innovation. It’s just the reality of liquidity, trust, and market gravity. Novelty gets attention. Scale gets allocations.

One of the more interesting data points came from Morgan Stanley’s Bitcoin Trust, or MSBT, which recorded about $193.6 million in first-month net inflows with no daily outflows. That’s a strong start, especially for a product charging a 0.14% management fee, one of the lowest in the US spot Bitcoin ETF market. Amy Oldenburg, Morgan Stanley’s head of digital assets, said early demand came mainly from self-directed clients.

“no single day of net outflows”

That detail matters more than it first appears. When a new product pulls in capital without a single red day in its first month, it suggests the demand is sticky rather than speculative chatter. And the low fee is doing real work here. In the ETF world, competition increasingly shifts from product novelty to cost and liquidity. Translation: if your fund is expensive, clunky, or both, investors will walk right past it.

Beyond ETF flows, regulation is still shaping the market in ways traders can’t ignore. Galaxy Digital said the CLARITY Act could move forward in the US Senate Banking Committee if key Democratic senators support it. The bill was originally introduced in July 2025, but momentum stalled in January after Coinbase withdrew its support. That’s a useful reminder that crypto legislation is rarely a clean sprint. It’s more like dragging a refrigerator uphill while everyone argues about who wrote the label.

The bill matters because clearer market structure rules could open the door to more institutional participation. When firms know whether an asset is treated as a security, a commodity, or regulatory mud, they can actually build products without tripping over legal landmines every five minutes. According to Galaxy Digital, senators Ruben Gallego and Angela Alsobrooks were broadly supportive, while Mark Warner, Catherine Cortez Masto, Andy Kim, and Raphael Warnock were described as conditional supporters. Lisa Blunt Rochester could be a swing vote.

That’s the boring-looking part of crypto that actually moves markets. Not memes. Not celebrity endorsements. Not breathless price targets from people who couldn’t find a balance sheet if it slapped them. Market structure is where adoption gets either unlocked or strangled.

South Korea is taking a much harder line on the compliance side. The South Korea National Tax Service is building an AI-powered crypto tax monitoring system with a budget of about $2.2 million. The stated goal is to “track virtual-asset transactions and crack down on tax evasion,” using systems that “integrate exchange records with on-chain data.” Upbit and Bithumb are involved in the coordination effort.

“track virtual-asset transactions and crack down on tax evasion”

“integrate exchange records with on-chain data”

That’s the double-edged sword of mainstream adoption. The same plumbing that makes crypto easier to buy also makes it easier to monitor. Non-custodial wallets still offer some privacy advantages, but once exchange records, blockchain analytics, and AI systems get stitched together, the net closes fast. The promise of financial freedom is real. So is the state’s appetite for receipts.

South Korea also plans to begin taxing crypto gains at 22% starting January 1, 2027, on annual gains above about $1,800. So yes, crypto is maturing as an asset class. No, that doesn’t mean regulators are suddenly feeling generous.

Large-holder behavior continues to add another layer of tension. Garrett Jin reportedly deposited 577,896 ETH to Binance over four days, worth about $1.35 billion. The position may reflect an unrealized loss of about $1.3 billion. That’s a brutal reminder that giant balances do not equal ironclad conviction once the market turns against you.

A large exchange deposit is not always an instant sell signal. Sometimes whales move coins for custody changes, collateral management, or internal restructuring. But let’s not kid ourselves: when nearly $1.35 billion in ETH heads to Binance, traders are going to notice. In crypto, “nothing to see here” is usually followed by everybody staring harder.

Corporate Bitcoin treasury strategy is still alive in Europe too. French listed company Capital B raised €15.2 million to expand its Bitcoin treasury strategy, with participation from Adam Back and Tobam. That’s another sign that some companies still view Bitcoin as the cleanest reserve asset in a monetary environment that keeps rewarding hard assets and punishing idle cash.

Whether every corporate treasury deserves applause is a separate question. Some firms use Bitcoin wisely as a long-term reserve hedge. Others just want a flashy ticker and a press release before reality checks their balance sheet. But the underlying point stands: Bitcoin treasury adoption isn’t dead, and for a subset of companies, it remains a rational move.

Binance also announced new spot pairs for MEGA/U, TON/U, and TON/USD1, along with a zero-fee promotion for certain orders. Listings still matter because they can deliver liquidity and visibility almost overnight. That doesn’t make the listed assets good, bad, or even useful. It just means more people can trade them. In crypto, that alone is enough to set off the sirens.

Key questions and takeaways

• Which crypto ETFs are attracting the most money right now?
  Bitcoin ETFs are still leading by a wide margin, with BlackRock’s IBIT dominating weekly inflows.
• Is Ethereum seeing the same level of enthusiasm as Bitcoin?
  No. ETH ETF inflows are positive, but the demand is more mixed and far less decisive than BTC.
• Are altcoin spot ETFs gaining traction?
  Yes, Solana and XRP products are drawing steady inflows, but they remain small compared with Bitcoin and Ethereum.
• Why is BlackRock IBIT such a big deal?
  Because scale, brand trust, liquidity, and fee sensitivity are driving ETF demand more than hype ever could.
• Why is GBTC still losing money?
  GBTC remains structurally disadvantaged versus newer, cheaper spot Bitcoin ETFs.
• What does Morgan Stanley’s Bitcoin Trust suggest?
  It suggests fresh, low-fee Bitcoin products can attract strong early demand, especially from self-directed investors.
• Could the CLARITY Act matter for crypto markets?
  Yes. Clearer US market rules could encourage more institutional participation and reduce legal uncertainty.
• How is South Korea approaching crypto taxation?
  It is building AI-driven monitoring systems to track crypto transactions and prepare for future enforcement.
• Does a huge ETH deposit to Binance mean selling is coming?
  Not always, but it is a warning sign. Big exchange deposits often signal potential sell pressure.
• What does Capital B’s fundraising show?
  Corporate Bitcoin treasury adoption is still alive, especially among companies looking for hard-money exposure.

The bigger picture is hard to miss. Bitcoin ETFs are still the cleanest institutional on-ramp in crypto. Ethereum is holding its ground. Solana and XRP are carving out small ETF niches. Regulators are getting sharper, tax enforcement is getting nastier, and corporate treasuries are still betting on Bitcoin as the least bad monetary asset on offer.

That’s not hype. That’s the market doing what it does: rewarding liquidity, punishing clunky products, and slowly dragging crypto deeper into the financial system while governments sharpen their pencils and whine about compliance. Welcome to mainstream adoption, clipboard and all.
