Q1 2026 13F filings reveal a fractured institutional landscape in U.S.-listed crypto exchange-traded funds. Jane Street cut BlackRock IBIT holdings by 71% and Fidelity FBTC by 60%, redirecting $82 million into Ethereum ETFs. JPMorgan moved in the opposite direction, raising IBIT exposure 175% to 8.3 million shares. Wells Fargo increased Ethereum ETF holdings by 63.5% while slashing Galaxy Digital by 97%.
The net result: institutional ownership of Bitcoin ETF shares has climbed to 38% of total ETF assets, up from 24% a year earlier. Yet the composition of that ownership is shifting. Trading firms are rotating toward Ether. Banks are accumulating Bitcoin on drawdowns. The 13F data, covering $105 billion in Bitcoin ETF AUM and roughly $13 billion in Ethereum ETF AUM, shows a market where participants agree on the asset class but disagree sharply on which asset within it deserves marginal capital.
The SEC requires institutional investment managers with more than $100 million in qualifying assets to file Form 13F within 45 days of each quarter's end. The Q1 2026 filings, due by May 15, capture positions as of March 31, 2026 — a quarter during which Bitcoin fell 22% and Ether declined 29%.
Total AUM across U.S. spot Bitcoin ETFs stood at $105.01 billion as of May 13, 2026. Cumulative net inflows since the January 2024 launch exceed $60 billion. BlackRock's IBIT and Fidelity's FBTC control roughly 80% of those flows.
Ethereum ETFs, launched in July 2024, held approximately $12.3–13.8 billion in AUM as of Q1 2026, with cumulative net inflows approaching $14 billion. BlackRock's ETHA leads with over $6.5 billion in assets.
Institutional ownership, as captured by 13F filings, now represents 38% of total Bitcoin ETF shares, up from 24% a year prior. The denominator grew — total ETF assets are larger — but institutional allocations grew faster. According to Bloomberg Intelligence analyst Eric Balchunas, advisors have become the largest 13F filer category by a wide margin.
Jane Street, the quantitative trading firm that reported $16.1 billion in Q1 2026 trading revenue, executed the most visible repositioning among major 13F filers.
Bitcoin ETF reductions:
Ethereum ETF additions:
Crypto equity increases:
The pattern is not a crypto exit. It is a reallocation. Jane Street reduced direct Bitcoin ETF exposure by approximately $775 million while adding $82 million in Ethereum ETFs and expanding crypto equity positions in Coinbase, Riot, and Galaxy Digital. The net reduction in crypto-adjacent positions is substantial but selective — the firm appears to have rotated from spot Bitcoin ETF exposure toward a mix of Ether ETFs and crypto equity.
This aligns with Jane Street's role as a market maker. The firm's 13F reflects inventory positioning, not a directional bet. A 13F captures long positions in U.S.-listed securities on a single day. It shows nothing about short positions, derivatives, options, or offshore holdings.
JPMorgan moved in the opposite direction from Jane Street. The bank's Q1 2026 filing shows:
The bank added approximately $162 million in IBIT value during a quarter when Bitcoin dropped 22%. The purchases were spread across multiple products, suggesting a deliberate allocation strategy rather than a position in a single fund.
JPMorgan's accumulation during a downturn contrasts with the broader 13F trend from Q4 2025, when 13F filers were net sellers, cutting exposure by nearly $1.6 billion — equivalent to roughly 25,000 BTC. Brevan Howard, for example, slashed its IBIT position 86% from 36.7 million shares at peak to 5.5 million shares by year-end 2025, reducing its stake from approximately $2.4 billion to $275 million.
JPMorgan's Q1 buying into the drawdown represents a reversal of the late-2025 institutional de-risking trend.
Wells Fargo's Q1 2026 filing reveals a targeted Ethereum allocation built during sustained price weakness.
Ethereum ETF positions:
The accumulation occurred while spot Ether ETFs experienced three consecutive months of net outflows totaling roughly $769 million. Ether posted back-to-back quarterly declines of 28% (Q4 2025) and 29% (Q1 2026). Wells Fargo was buying what most of the market was selling.
Simultaneously, Wells Fargo made aggressive changes to crypto equity holdings:
The combination — accumulating Ethereum ETFs and MicroStrategy while exiting Galaxy Digital almost entirely — suggests a portfolio rebalancing toward larger, more liquid vehicles.
Daily ETF flow data from May 2026 adds context beyond the Q1 filing snapshot.
On May 13, U.S. spot Bitcoin ETFs recorded $635 million in net outflows — the largest single-day exit since January 29. BlackRock's IBIT accounted for $284.7 million of the total. On the same day, Ethereum ETFs saw $36.3 million in outflows, with ETHA losing $21.1 million.
According to Glassnode data, the seven-day moving average for U.S. spot Bitcoin ETF flows dropped to negative $88 million per day — the weakest reading since February 2026.
However, the monthly trend tells a different story. April 2026 finished with $1.97 billion in net Bitcoin ETF inflows, the strongest month of the year. Early May saw a nine-day inflow streak totaling $2.7 billion before the May 13 reversal.
Ethereum ETFs crossed $250 million in cumulative inflows over three consecutive sessions in early May, driven by BlackRock's ETHA and ETHB products.
The pattern: institutional money is entering both products, but the daily volatility of flows is increasing. Single-day swings of $500 million or more in Bitcoin ETFs have become routine in 2026, compared with sub-$200 million daily moves through most of 2024.
The 13F is a limited instrument. Several caveats apply to any analysis of institutional crypto ETF positioning:
Snapshot bias. The filing reflects positions on March 31 only. Jane Street may have rebuilt Bitcoin positions the next day. JPMorgan may have trimmed. The data is 45 days stale at publication.
No short or derivative visibility. A firm showing reduced IBIT longs may hold equivalent Bitcoin exposure through futures, options, swaps, or offshore vehicles. Jane Street, as a market maker, almost certainly holds significant offsetting positions not captured in the filing.
Custodial vs. proprietary. Some 13F positions, particularly at banks like JPMorgan and Wells Fargo, may represent client custody or managed-account holdings rather than the institution's own capital.
Size context. Jane Street's $82 million Ethereum ETF position represents less than 0.5% of its $16.1 billion quarterly trading revenue. JPMorgan's $390 million IBIT position is under 0.1% of the firm's $4.1 trillion balance sheet. These are measurable but not material positions for firms of this scale.
Institutional crypto ETF ownership reached 38% of total Bitcoin ETF assets in Q1 2026, up from 24% a year earlier. The class of holder is changing even as total inflows grow.
Jane Street cut Bitcoin ETF holdings by $775 million and added $82 million in Ethereum ETFs. The rotation is directional within crypto, not an exit from crypto.
JPMorgan accumulated $162 million in additional IBIT exposure during a 22% Bitcoin drawdown, reversing the Q4 2025 institutional de-risking trend.
Wells Fargo built Ethereum ETF positions into weakness, raising ETHA holdings 63.5% while the broader Ethereum ETF market experienced $769 million in outflows over three months.
Daily flow volatility is increasing. Single-day Bitcoin ETF moves exceeding $500 million are now routine, compared with sub-$200 million swings through 2024.
13F data is structurally incomplete. It captures long U.S. equity positions on one day per quarter. It excludes shorts, derivatives, offshore holdings, and any changes since March 31.
The Q1 2026 13F season reveals an institutional market that has moved past the question of whether to hold crypto ETFs. The question is now which crypto ETF, at what weight, and under what market conditions.
The divergence between Jane Street (rotating to Ether) and JPMorgan (accumulating Bitcoin on drawdowns) reflects genuinely different views on relative value within the asset class. Wells Fargo's quiet Ethereum accumulation during three months of outflows adds a third data point: selective contrarian allocation at a bank with $1.9 trillion in assets.
The aggregate numbers — 38% institutional ownership, $105 billion in Bitcoin ETF AUM, $60 billion in cumulative inflows — describe a market that has institutional participation baked in. The 13F filings describe what those institutions are doing with their positions, and the answer in Q1 2026 is: not the same thing.
The economic value generated by crypto ETF infrastructure — custody fees, management fees, trading spreads, market-making revenue — accrues to a small number of asset managers, exchanges, and custodians. BlackRock, Fidelity, and Coinbase capture the majority of this value chain. The institutional rotation visible in 13F filings is, at its core, a competition among these intermediaries for the next tranche of allocator capital.
