The first half of 2026 has been a defining period for the crypto ETF landscape. Bitcoin Spot ETFs, which launched in January 2024, have matured into a $120+ billion asset class. Ethereum Spot ETFs, following their approval in mid-2024, have carved out their own — albeit smaller — niche.
Total Assets Under Management (AUM)
Bitcoin Spot ETFs ($124.6B as of June 30, 2026)
Bitcoin ETFs continue to dominate, with BlackRock’s iShares Bitcoin Trust (IBIT) holding roughly $48 billion in AUM alone. Fidelity’s FBTC follows at $32 billion, while the remaining players — Ark 21Shares (ARKB), Bitwise (BITB), and VanEck (HODL) — share the rest.
The steady accumulation pattern observed throughout 2024 and 2025 has continued into 2026, with net inflows averaging $420 million per week during Q2.
Ethereum Spot ETFs ($26.8B as of June 30, 2026)
Ethereum ETFs have grown steadily but remain roughly one-fifth the size of their Bitcoin counterparts. BlackRock’s ETHA leads with $9.1B, followed by Fidelity’s FETH at $6.4B. The Grayscale Ethereum Trust conversion (ETHE), which started as the largest, has seen consistent outflows.
The key takeaway: Ethereum ETFs are growing at a faster percentage rate than Bitcoin ETFs in 2026, but the absolute gap in AUM has actually widened from roughly $85B (end of 2025) to $98B.
Institutional Adoption Trends
Bitcoin ETFs continue to be the primary vehicle for institutional crypto exposure. 13F filings from Q1 2026 revealed:
- 1,847 institutional holders across all Bitcoin ETFs (up 34% from Q1 2025)
- 287 new institutional buyers entered Bitcoin ETFs in Q1 alone
- Average allocation: 0.84% of portfolio (up from 0.52% in Q1 2025)
For Ethereum ETFs:
- 612 institutional holders across all Ethereum ETFs
- 98 new institutional buyers in Q1 2026
- Average allocation: 0.31% of portfolio
Trading Volume and Liquidity
Bitcoin ETFs command approximately 78% of all crypto ETF trading volume in 2026. The average daily trading volume for Bitcoin ETFs stands at $4.2 billion, compared to $1.1 billion for Ethereum ETFs.
Fee War Continues
| ETF Provider | Bitcoin ETF Fee | Ethereum ETF Fee |
|---|---|---|
| BlackRock | 0.12% | 0.15% |
| Fidelity | 0.12% | 0.19% |
| Bitwise | 0.12% | 0.12% |
| VanEck | 0.10% | 0.10% |
| Franklin Templeton | 0.09% | 0.09% |
Stake Yield — The Ethereum ETF Advantage
The most significant divergence in 2026 is the staking yield advantage for Ethereum ETFs. Several Ethereum ETF providers now include staking components: Fidelity FETH generates ~3.2% annual yield, Bitwise ETHW ~3.1%, and Franklin Templeton EZET ~3.0%.
Key Events That Shaped H1 2026
- Jan 15: Fed holds rates steady → Both ETFs +3.5% weekly inflow
- Feb 8: SEC clarifies staking rules → ETH ETFs +8% weekly inflow
- Mar 12: ETH staking yield narrative peaks → FETH overtakes ETHE in AUM
- Apr 22: Bitcoin halving anniversary rally → BTC ETFs $2.1B weekly inflow
- Jun 3: Ethereum Pectra upgrade concerns → ETH ETFs temporary -$800M outflow
Outlook for H2 2026
Bitcoin ETFs: Expect continued steady accumulation with potential acceleration if the Fed signals rate cuts. Many analysts project combined Bitcoin ETF AUM reaching $150-180B by year-end. Ethereum ETFs: Growth will likely accelerate as more advisors become comfortable with staking-enabled products. AUM could reach $35-40B by December.
