Crypto funds logged their strongest weekly inflows since January, pulling in $1.1 billion, as Bitcoin ETFs drove the surge while Ethereum funds stayed negative.[1] This marked a turnaround, with year-to-date crypto ETF flows flipping positive at $2.3 billion, led by BlackRock’s IBIT.[1]

- IBIT dominated with $871 million weekly inflows, also leading monthly ($719 million) and year-to-date ($1.72 billion) figures among all crypto ETFs.[1]
- Year-to-date crypto ETF flows turned positive at $2.3 billion, reversing prior deficits primarily through Bitcoin fund gains.[1]

BTC ETF Inflows Surge to 4-Month High
Bitcoin spot ETFs captured the bulk of last week’s action. CoinShares data shows $1.9 billion net into BTC funds, pushing total crypto ETF inflows to $1.1 billion-the best week since January.[1] BlackRock’s IBIT alone accounted for $871 million, or nearly 80% of the total, underscoring its dominance.[1]
Year-to-date, BTC ETFs flipped the script for broader crypto funds. Cumulative flows hit positive $2.3 billion, with IBIT’s $1.72 billion offsetting outflows from rivals like Fidelity’s FBTC (-$1.58 billion), ARK 21Shares ARKB, and Grayscale GBTC.[1] This concentration in top performers highlights how a few products dictate the narrative.
Farside Investors tracks daily flows, noting recent peaks like $1,119.9 million maximum inflows against outflows as low as -$528.3 million.[7] No direct data confirms sustained multi-week momentum beyond this period; trackers like CoinGlass show total BTC ETF net inflow at +$57.14 billion cumulatively, with daily nets varying.[3]
ETH ETF Flows Lag Amid BTC Dominance
Ethereum ETFs told a different story. Weekly net stood at -$130 million, per CoinShares, even as some daily inflows emerged-like $7.7 million on April 13.[1][2] Cumulative ETH ETF inflows reached $11.68 billion, but recent weeks reversed prior gains with three straight outflows totaling $308 million before this uptick.[2]
A YouTube market update from April 14 noted ETH price outperformance-up 8% in 24 hours vs. BTC’s 5%-alongside a 41% jump in Ethereum transactions.[2] Yet BTC ETFs saw $325.8 million outflows that day, led by FBTC (-$229 million) and ARKB (-$63 million).[2] Ether weekly inflows for the period ending April 10 hit $187 million, the strongest in 2026.[2]
Glassnode’s ETF flow estimates cover both BTC and ETH products, using shares outstanding and basket crypto amounts where available.[4] Data as of March 31, 2026, shows variability, with GBTC at -6.3579 (units unclear in snippet).[4] Trackers disagree slightly: CoinGlass lists ETH net flows without specific weekly positives matching CoinShares exactly.[5]
On-Chain Data Reveals Holder Behavior Ties to Crypto Funds Inflows
Glassnode and similar platforms provide on-chain context beyond ETF headlines. US spot ETF flows estimate daily net changes in holdings for 11 BTC ETFs and 9 ETH ones, sourced from issuers.[4] This ties institutional ETF demand to actual BTC/ETH reserves.
For deeper angles, consider exchange flows versus ETF inflows. No direct weekly exchange inflow data here, but CoinGlass cumulative BTC ETF net +721.09K BTC implies reduced sell pressure if held off exchanges.[3] Custom metric: Inflow-to-AUM ratio for top BTC ETFs shows IBIT’s efficiency-$871M weekly on growing AUM base versus FBTC’s mixed record.[1][3]
Here’s an original comparison table of top BTC ETFs’ weekly vs. YTD flows (millions USD, sourced data):
| ETF | Weekly Inflow | YTD Flow | Fee (%) |
|---|---|---|---|
| IBIT | 871 | 1,720 | 0.25 |
| FBTC | 98 | -1,580 | 0.25 |
| GBTC | Outflow | Outflow | 1.50 |
| ARKB | Outflow | Outflow | 0.21 |
Another custom metric: BTC ETF net inflow per BTC held (cumulative). CoinGlass total +$57.14B equates to +721.09K BTC, or roughly $79,200 per BTC inflow-stable amid price swings.[3] ETH lacks equivalent granularity here, limiting direct parallels.
Long-term holder (LTH) accumulation rates from platforms like Glassnode typically rise with ETF inflows, as institutions bypass exchanges.[4] No exact LTH data in results, but sustained ETF nets like +$240.40M daily suggest potential LTH supply lockup over 12-36 months if replicated.[3] Wallet clustering patterns (e.g., via Arkham/Nansen) often show ETF custodians clustering large inflows, reducing retail float-though specific 2026 clusters absent here.
Broader Crypto ETF Landscape Beyond BTC and ETH
XRP and SOL ETFs added $178M and $218M weekly, per CoinShares-outpacing ETH’s negative.[1] CoinGlass monitors these, noting AUM trends but blank recent dailies ($0 placeholders).[5] Yearly performance lacks specifics, with strongest/weakest months undefined in data.[5]
Futures vs. spot: Spot BTC ETFs lead fiat absorption, per analytics, while futures carry roll costs.[5] Total crypto ETF volume hit $3.48B daily recently, with AUM undisclosed in snippets.[3] Over 90 days, flows trend neutral without granular splits.[5]
Unique Angle: ETF Fee Competition and Flow Concentration
Fees drive allocation. IBIT/FBTC at 0.25%, BITB 0.20%, GBTC’s 1.50% handicap it.[7] Original metric: Fee-adjusted inflow efficiency-IBIT’s $871M / 0.25% fee implies high appeal vs. GBTC outflows despite size.[1][7]
| ETF | Weekly Flow (M) | Fee (%) | Efficiency (Flow/Fee) |
|---|---|---|---|
| IBIT | 871 | 0.25 | 3,484 |
| FBTC | 98 | 0.25 | 392 |
| GBTC | Negative | 1.50 | Negative |
This concentration-IBIT 79% of weekly total-raises questions on diversification. CoinMarketCap lists global BTC ETFs with NAV/AUM, but US spot dominates.[6]
Risks and Uncertainties in Crypto Funds Post Best Week
Downside scenario: Daily BTC outflows like April 13’s -$325.8M (FBTC -229M) could extend if risk-off hits, erasing weekly gains.[2] ETH’s prior three-week -$308M outflows signal vulnerability to rotation reversals.[2]
Uncertainties abound. Sources conflict-CoinShares weekly $1.1B total vs. CoinGlass/Coingecko blanks or cumulatives without weekly match.[1][3][5] Glassnode ends March 31 data, missing April peaks.[4] No on-chain exchange flows or LTH rates confirmed here; analysis limited to ETF trackers. Projections distinguish baseline (modest inflows if fees stable) from upside (ETH catch-up per transaction surge).[2] Farside max $1,119.9M vs. min -$528.3M shows volatility.[7]
Long-term (12-36 months): Cumulative BTC +57B/+721K BTC supports growing institutional base if inflows average $240M daily, but ETH’s $11.68B record needs weekly consistency.[2][3] SOL/XRP breadth helps, yet BTC leads 80%+ share.[1]
One data-driven implication: Cumulative BTC ETF holdings at +721K BTC, tied to weekly surges like IBIT’s, point to institutionalized supply absorption over 12-36 months if net flows hold above $200M weekly averages.[3][1]
