The crypto ETF landscape continues to evolve at a rapid pace, with significant inflows into U.S. spot Bitcoin ETFs, new product filings, and expanding regulatory approvals across global markets. This week’s report covers the latest performance metrics, product developments, and regulatory shifts shaping the future of digital asset investment vehicles.
U.S. Bitcoin Spot ETFs Attract $2.21 Billion in Net Inflows
Last week marked a strong bullish signal as U.S. Bitcoin spot ETFs recorded five consecutive days of net inflows, totaling $2.214 billion**. The combined net assets under management (AUM) now stand at **$133.17 billion, reflecting growing institutional and retail confidence in regulated Bitcoin exposure.
Three funds led the charge in capital inflows:
- iShares Bitcoin Trust (IBIT): +$1.31 billion
- Fidelity Wise Origin Bitcoin Fund (FBTC): +$504 million
- ARK 21Shares Bitcoin ETF (ARKB): +$268 million
This sustained momentum underscores investor appetite for secure, exchange-listed Bitcoin access. The dominance of IBIT and FBTC highlights trust in established financial brands like BlackRock and Fidelity to lead this new asset class.
Ethereum Spot ETFs Gain Traction with $283 Million Inflow
U.S. Ethereum spot ETFs also saw positive movement, logging $283 million in net inflows** over four days. Total AUM reached **$9.88 billion, signaling increasing interest in Ethereum’s long-term value proposition amid network upgrades and ecosystem growth.
The standout performer was BlackRock’s Ethereum Trust (ETHA), which attracted $233 million in new capital. Notably, three other Ethereum ETFs reported no movement, suggesting market concentration around early leaders with strong brand recognition and liquidity.
While Ethereum ETFs are still in their early stages compared to Bitcoin counterparts, the inflow trend indicates that investors are beginning to diversify within the crypto asset class through regulated products.
Hong Kong Crypto ETFs Show Stability Amid Minimal Fluctuations
In Asia, Hong Kong-based spot Bitcoin ETFs experienced negligible outflows of just 0.001 BTC, maintaining a total AUM of $447 million. Among issuers:
- Harvest Fund reduced its holdings to 301.44 BTC
- China Asset Management (Huaxia) held steady at 2,230 BTC
Hong Kong’s Bitcoin ETFs continue to demonstrate resilience despite global volatility, serving as a gateway for mainland Chinese investors seeking compliant digital asset exposure.
Meanwhile, Hong Kong’s Ethereum spot ETFs saw no inflows, with AUM stabilizing at $53.29 million. The lack of movement may reflect cautious sentiment or limited product awareness among regional investors.
Rising Activity in Crypto ETF Options Markets
Derivatives markets are increasingly integrating crypto ETFs into broader trading strategies. As of June 27, the nominal trading volume for U.S. Bitcoin spot ETF options reached $1.04 billion, with a bullish put/call ratio of 4.21, indicating strong demand for call options.
Total open interest stood at $16.36 billion as of June 26, with a put/call ratio of 2.07, further reinforcing optimistic market sentiment.
Additionally, the implied volatility for these options sits at 42.74%, reflecting expectations of continued price movement in underlying assets. These figures suggest that professional traders are actively using ETF-linked derivatives to hedge positions or speculate on future price action.

Expert Insights: What’s Next for Crypto ETFs?
Ripple-SEC Case Closure Paves Way for XRP ETF
ETF expert and CEO of ETF Store, Nate Geraci, stated that Ripple’s withdrawal from its lawsuit against the SEC clears the path for an XRP spot ETF — and potentially opens the door for giants like BlackRock to enter the space.
With regulatory clarity improving, XRP could become one of the next major assets to receive SEC-approved ETF treatment.
Hester Peirce: In-Kind Redemptions “On the Horizon”
SEC Commissioner Hester Peirce suggested that in-kind creation and redemption mechanisms for crypto ETFs may soon be approved. Speaking at a Bitcoin policy event, she noted that such applications are “in the pipeline” and that approval is likely “at some point.”
In-kind redemptions are critical for reducing tax liabilities and improving market efficiency — their adoption would mark a major milestone for crypto ETF maturity.
Frequently Asked Questions (FAQ)
What are crypto spot ETFs?
Crypto spot ETFs are exchange-traded funds that directly hold digital assets like Bitcoin or Ethereum. Unlike futures-based ETFs, they track the real-time price of the underlying asset, offering more accurate exposure.
Why are inflows important for crypto ETFs?
Sustained net inflows indicate growing investor confidence and capital commitment. They also enhance liquidity and reduce tracking errors, making ETFs more efficient investment tools.
What is in-kind redemption and why does it matter?
In-kind redemption allows authorized participants to exchange ETF shares for the actual underlying assets (e.g., BTC), rather than cash. This mechanism reduces taxable events and improves arbitrage efficiency, lowering premiums/discounts.
Are staking-based crypto ETFs available yet?
While not yet widely available in the U.S., REX Shares is preparing to launch the first staking-enabled Solana ETF. Such products aim to provide both price exposure and yield from network participation.
How do global regulators view crypto ETFs?
Regulatory approaches vary: the U.S. remains cautious but progressing; Hong Kong has embraced spot crypto ETFs; South Korea is moving toward legal recognition; and European markets already offer ETPs. Harmonization remains a long-term goal.
Can traditional investors access crypto via ETFs safely?
Yes — crypto ETFs offer a regulated, custodied, and exchange-traded way to gain exposure without managing private keys. They’re ideal for retirement accounts, institutional portfolios, and retail investors seeking simplicity and security.
