Bitcoin and Ethereum ETF Approvals in the US: Timeline, Fees & In-Kind Changes

For over a decade, investors waited for the U.S. Securities and Exchange Commission (SEC) to give the green light to spot Bitcoin exchange-traded funds (ETFs). That wait ended on January 10, 2024, when the SEC approved the first batch of these products. Just six months later, on July 23, 2024, the door opened for Ethereum is a decentralized platform that enables smart contracts and staking rewards, leading to the approval of the first spot Ethereum ETFs. These two milestones marked a fundamental shift in how traditional finance views digital assets. But the story didn't stop at initial approval. The regulatory landscape has continued to evolve, particularly with the introduction of in-kind creation mechanisms in 2025, which changed how these funds operate under the hood.

If you are looking to invest through an ETF or just want to understand why the market reacted so strongly to these approvals, you need to look beyond the headlines. This guide breaks down the timeline, the technical differences between Bitcoin and Ethereum ETFs, the fee structures, and the recent operational changes that affect your costs and tax implications.

The Regulatory Timeline: From Rejection to Approval

The path to approval was long and winding. Between 2013 and 2023, the SEC rejected 13 applications for spot Bitcoin ETFs. The turning point came not from the SEC itself, but from the courts. In August 2023, the U.S. Court of Appeals for the D.C. Circuit ruled in Grayscale Investments LLC v. SEC that the commission had applied inconsistent standards when rejecting these funds. This legal pressure forced the SEC to reconsider its stance.

Once the dust settled, the approvals happened quickly:

• January 10, 2024: First spot Bitcoin ETFs approved.
• July 23, 2024: First spot Ethereum ETFs approved.
• July 29, 2025: SEC approves in-kind creation and redemption for crypto ETPs.
• October 2025: Expanded framework for in-kind processing across multiple crypto assets.

This progression shows a clear pattern: the SEC moved from skepticism to structured acceptance, prioritizing a "fit-for-purpose" regulatory framework as stated by Chairman Paul S. Atkins in late 2025.

Bitcoin vs. Ethereum ETFs: Key Differences

While both are spot crypto ETFs, they are not identical products. The core difference lies in the underlying asset's technology. Bitcoin uses proof-of-work consensus, meaning it doesn't generate yield. Ethereum uses proof-of-stake, which allows validators to earn staking rewards. This distinction directly impacts how the ETFs are managed and what returns investors might see.

Note that not all Ethereum ETFs stake their holdings. As of September 2025, only five of the eleven approved Ethereum ETFs elected to participate in staking. Grayscale’s ETHE, for instance, allocated about 4.2% of its ETH holdings to staking, generating quarterly rewards distributed to shareholders. If you choose a non-staking Ethereum ETF, you will only capture price appreciation, similar to Bitcoin.

The Game Changer: In-Kind Creation and Redemption

When these ETFs first launched, they operated on a "cash-only" model. This meant that when large institutional investors (authorized participants) wanted to create new shares, they had to pay cash to the fund, which then bought the crypto. When redeeming, the fund sold the crypto and paid cash back. This process often triggered taxable events and added friction.

In July 2025, the SEC approved In-Kind Creation is a mechanism allowing authorized participants to exchange physical crypto assets for ETF shares without selling. This aligns crypto ETFs with traditional commodity ETFs like gold. Now, investors can deliver actual Bitcoin or Ether to the fund to receive shares, or redeem shares for the underlying crypto. This change eliminated unnecessary sales, reducing tax liabilities and operational costs by an estimated 0.15% to 0.25% annually.

The impact has been immediate. By October 2025, BlackRock processed over $3 billion in in-kind conversions. For large holders, this offers a way to hold crypto within a regulated structure while maintaining control over their specific coins, useful for estate planning or collateralization in prime brokerage arrangements.

Market Performance and Institutional Adoption

The adoption numbers speak to the scale of this shift. By the end of September 2025, the spot Bitcoin ETF market reached $54.3 billion in assets under management (AUM), with BlackRock’s iShares Bitcoin Trust (IBIT) holding a 31.2% market share. Ethereum ETFs collectively held $18.7 billion, led by Grayscale’s ETHE with a 27.3% share.

However, market dynamics have diverged recently. While Bitcoin ETFs experienced net outflows of $1.2 billion in Q3 2025 due to rising interest rates, Ethereum ETFs saw net inflows of $478 million. This suggests that investors may be rotating toward Ethereum’s utility features, such as staking yields, during periods of macroeconomic uncertainty.

Institutional sentiment remains largely positive. A survey of 142 institutional investors found that 78% prefer holding Bitcoin through ETFs for easier collateralization. Retail sentiment is also strong, with 63% of comments on major crypto forums expressing positive views on Ethereum ETFs, though complaints about high fees from legacy providers like Grayscale remain common.

What This Means for Your Investment Strategy

The approval of these ETFs has lowered the barrier to entry for traditional investors who want exposure to crypto without managing private keys. However, it’s not a one-size-fits-all solution. Here is how to approach it:

1. Check the Staking Policy: If you buy an Ethereum ETF, verify if it stakes. If you want yield, look for providers like Grayscale or Fidelity that distribute staking rewards. If you don’t care about yield, a lower-fee non-staking option might be better.
2. Mind the Fees: Fees vary significantly. Fidelity’s FBTC charges 0%, while Grayscale’s GBTC charges 0.9%. Over time, this difference compounds. Compare the expense ratios carefully before choosing.
3. Consider Tax Implications: With in-kind creation now available, large holders can avoid capital gains taxes when moving assets into ETFs. For retail investors, buying and selling ETF shares still triggers standard capital gains rules based on your cost basis.
4. Monitor Premiums: Bitcoin ETFs currently trade at a 0.08% premium to Net Asset Value (NAV), while Ethereum ETFs trade at 0.23%. Trading at a significant premium means you’re paying more than the underlying asset is worth. Keep an eye on these spreads.

Looking ahead, analysts project the combined market for Bitcoin and Ethereum ETFs could reach $150 billion by December 2026. The SEC’s open stance on other cryptocurrencies suggests that Solana, XRP, or other assets could follow, but for now, Bitcoin and Ethereum remain the blue chips of the crypto ETF world.
