Bitcoin (BTC) ETF Inflows Hit $3.8B in Three Weeks, Led by BlackRock's IBIT

Three-Week ETF Streak Tops $3.8B

US-listed spot Bitcoin ETF products absorbed $986.9 million in the week ending Friday, lifting three-week net inflows to $3.8 billion — the strongest consecutive stretch for the funds in 2026 and roughly 7% ahead of the prior week, according to aggregate flow data tracked by SoSoValue. The products, which custody the coin directly and give brokerage accounts price exposure without wallets, private keys or exchange onboarding, have become the market's cleanest gauge of traditional-finance demand since their debut. After a brutal start to 2026 that left the year's flow ledger underwater, appetite has snapped back — and it held even as the spot tape wobbled. On Thursday, with the coin pushed intraday below $79,000, the cohort still took in $730.9 million, the largest single-day haul since January 14, and BlackRock's iShares Bitcoin Trust (IBIT) captured roughly $454 million of it. Friday brought a cooldown, not a reversal: daily net inflows eased to $174.6 million, a reading Farside Investors' tally matches, with IBIT accounting for $117.4 million — about 67% of the day's total. Fidelity's Wise Origin Bitcoin Fund (FBTC) was the only other product with activity, adding $57.2 million, while every other US spot Bitcoin ETF recorded zero net flow. That whale-scale concentration in a single product — rather than broad distribution across the lineup — has defined the entire streak. Net assets stood at $101.3 billion at Friday's close after briefly touching $103.3 billion a day earlier, and cumulative net inflows since launch reached $55.6 billion.

Where the Streak Falls Short

Here is where the streak falls short. Year-to-date, the cohort remains roughly $1 billion net negative — three strong weeks have blunted, but not erased, the outflow wave from early 2026. The demand that arrived was also narrow: IBIT and FBTC were Friday's only participants, and the stretch's biggest days landed in the largest fund. Meanwhile, the rotation into Bitcoin came at the expense of its peers. US spot Ether ETF inflows dropped about 74% week over week, from $824.4 million to $218.4 million, while XRP ETF inflows fell 83%, from $110.5 million to just $19 million — and that altcoin rotation happened even though both categories stay positive on the year, at roughly $863 million for Ether funds and about $515 million for XRP funds. Institutional demand through ETF wrappers, which hold actual coins, differs from discretionary treasury plays such as a strategic bitcoin reserve, where governments or corporations accumulate on their own schedule rather than through daily market flow. Price action echoed the two-sided tape. Bitcoin slid from around $81,200 to briefly below $79,000 on Friday, yet ETF demand never turned negative on the week — flows moved on their own clock. At the time of writing the coin trades near $79,600, still up roughly 2.6% over seven days, per CoinGecko's live chart. For the on-market counterpart to those ETF creations, our exchange-reserve tracking shows a 1,818 BTC daily net inflow, meaning coins moved toward trading venues even as fund wallets soaked up supply. Our recent note on the Bitcoin-to-gold ratio hitting 18.17, its highest since January, captures the same hard-asset bid now showing up in ETF creations.

$79,500 Line Under the Lens

The rally found a fresh catalyst in Washington and the Fed. Governor Christopher Waller said inflation, while still above the 2% target, is showing signs of slowing, and that if the trend holds over the next two weeks he could support holding rates steady at the September 15-16 meeting — though he cautioned a rebound in August inflation could revive rate-hike talk. Markets focused on the dovish half of the message, and falling global bond yields fed the bid. Meanwhile, the Senate's calendar sets a cloture vote on the CLARITY Act (H.R. 3633) for September 15, requiring 60 votes to advance — a procedural step, not final passage — with the bill already cleared by the House in July 2025 and the Senate Banking Committee in May 2026. Eyes now turn to Friday's US jobs report.

Per-fund ledger details add texture to Friday's session: IBIT added roughly 1,470 BTC and FBTC 718 BTC, with cumulative net inflows since launch standing at $64.06 billion for IBIT and $10.33 billion for FBTC, against GBTC's $27.65 billion in cumulative net outflows. Daily trading volume across the Bitcoin funds hit $2.95 billion, and the day's Ethereum tape split along issuer lines — ETHA took in $57.79 million and the ETHB staking product $16.44 million, while Fidelity's FETH bled $48.30 million, about 19,670 ETH, leaving two-day Ether ETF net inflows at $167.85 million. Separately, CoinShares' latest market update argues that holding above $80,000 — a level reached after a climb from the $60,000 band — likely requires either a de-escalation of Iran-related tension or further erosion of confidence in US public debt, framing the rally's gold-like, safe-haven character.

Updated aggregate data from Thursday's session sharpens the picture of the streak's largest day. The cohort absorbed roughly 9,450 BTC in a single session, lifting cumulative net inflows to $55.9 billion — a newer reading than the $55.6 billion previously tallied — and pushing the funds' combined coin position to approximately 699,000 BTC. Total net assets were recorded at $99.61 billion, with daily trading volume across the products reaching $5.69 billion, well above the earlier $2.95 billion figure. One fund's Thursday buying alone corresponded to about $631 million in BTC, while a handful of products saw limited outflows. Market sources differed slightly on the day's total, with some calculating roughly $740 million versus the $730.9 million baseline, but the broad ledger stayed firmly positive — a signal, per the data, that institutional appetite for Bitcoin is accelerating again.

(as of 11:40 UTC) COINOTAG's proprietary 42-indicator composite S/R scoring engine rates the $79,507 support at 75/100, a confluence of Ichimoku Tenkan, a Flip R→S marker and the Fibonacci 0.114 level — and spot, at $79,636.00 and down 2.04% over 24 hours, sits just above it. Overhead, the $80,811.61 resistance scores 75/100 on Fibo 0.000, Donchian Upper, Swing High and ATR Upper sources. Funding sits at -0.0010%, open interest near $15.81 billion, and the long/short account ratio reads 1.11, with Fear & Greed at 73 (Greed) and the trend sideways. Holding $79,507 keeps a retest of $80,811.61 live; a daily close below it invalidates that path and exposes the $74,131.55 support (65/100, Ichimoku Kijun, Supertrend, HVN and Fibo 0.382), with a bearish MACD signal reinforcing the caution.
