Institutional capital flows into Bitcoin exchange-traded products have been uneven since their launch, but the week of March 9–13 produced the clearest directional signal of 2026 so far.
According to SoSoValue data cited in the announcement, Bitcoin spot ETFs recorded $767 million in net inflows across that five-day stretch — the first unbroken inflow streak spanning a full trading week for BTC ETFs this year. BlackRock‘s IBIT absorbed $600.1 million of that total, accounting for more than 78% of all net BTC ETF inflows across every competing product. The fund now holds over $55 billion in assets under management.
The concentration is notable. With the broader market still working through the effects of a January sell-off, one firm committing that volume to a single weekly window is a considered allocation decision, not a passive drift. The only meaningful counter-flow came from Grayscale‘s GBTC, which posted $25.9 million in outflows over the same period — a modest exit relative to the scale of inflows elsewhere.
Ether ETFs and the XRP Exception
Ethereum products followed the same directional pattern. ETH spot ETFs drew $160.9 million in net inflows for the week, with Fidelity‘s FETH leading at $90.1 million. Grayscale’s ETHE was again the category’s primary seller, recording $13.4 million in outflows.
XRP broke from the trend entirely. While BTC, ETH, and SOL products all attracted net capital, XRP spot ETFs recorded $28.07 million in net outflows — the only major crypto ETF category to finish the week in negative territory.
The Technical Setup Traders Are Watching
BTC is currently trading at $73,500, pressing against the upper trendline of a rising wedge formation that has rejected price at this level on each of the past six attempts. That pattern has conditioned a significant portion of the market to short the resistance, anticipating a pullback toward $64,000 or $60,000 — the levels identified as support if the rejection repeats.

The report argues this positioning creates an asymmetric risk for bears. Negative funding rates have been building through successive failed breakdowns, loading a short squeeze setup that grows more pressurized with each failed attempt to push price lower. A confirmed break and hold above the upper channel trendline and $75,000 would force those short positions to close — a mechanical buying wave that the analysis says points toward $80,000 as the first target, $84,000 next, and $90,000 as the outer level.
The setup does not resolve the directional question on its own. The same trendline has held as resistance six times. What the institutional inflow data changes is the weight behind any breakout attempt — BlackRock adding $600 million in a single week while retail sentiment remains cautious is the kind of structural demand that alters how resistance levels are tested.
