BlackRock and Fidelity were back on the bid last week, with Arkham data pointing to roughly $400 million in Bitcoin$62,304.50 purchases across the two giants. That came despite about $250 million in BTC sales over the same stretch, leaving a net positive read for institutional demand rather than a clean one-way punt. [1]
The immediate takeaway is simple: big ETF-linked players appear to be buying weakness, not fleeing it. For a market that has spent plenty of time obsessing over daily ETF flow tables, that matters more than the headline gross number alone.

What Arkham's data is showing
Blockchain analytics firm Arkham said on March 23 that BlackRock and Fidelity bought approximately $400 million worth of Bitcoin$62,304.50 last week while also offloading around $250 million. On net, that still implies meaningful accumulation, even if the path there was a bit messier than the clean "institutions are only buying" narrative CT usually prefers. [2]
Arkham also said it has made tracking data for BlackRock's Bitcoin holdings available on its platform, giving traders a closer look at wallet-level movements tied to one of the most important sources of BTC demand in this cycle. That does not mean every transfer is directional buying or selling in the purest sense, but it does offer more on-chain evidence than the usual vibes-heavy ETF chatter. [2]
ETF flows stayed positive, but only just
The broader ETF picture was constructive rather than euphoric. Total Bitcoin ETF inflows reached $93.1 million for the week, according to the source material. That is not the sort of number that screams fresh melt-up, but it does show the category remained in positive territory even as funds rotated and some selling took place under the bonnet. [3]
That distinction matters. Gross buying of $400 million sounds punchy, but if $250 million was also sold, the net effect is far smaller than the top-line figure suggests. For traders, this looks less like a fresh institutional frenzy and more like selective re-accumulation at current levels. [4]
BlackRock and Fidelity are not just any buyers. Their spotBitcoin$62,304.50 products sit at the core of the US ETF demand story, and their activity is watched because it can signal whether traditional finance allocators still see BTC as worth accumulating after pullbacks.
If Arkham's read is right, the pair used last week's softer tape to add exposure rather than de-risk across the board. That is a healthier signal than pure momentum chasing. It suggests at least some large allocators still view current prices as acceptable entry points, even if they are managing flows actively rather than blindly aping in.
It also hints that the institutional bid remains price-sensitive, not unconditional. Buying and selling in the same week is what you would expect from funds balancing creations, redemptions and inventory needs, not from a market in full price discovery mode.
A cleaner signal than sentiment, but not perfect
On-chain tracking of ETF-related wallets is useful, but it is worth staying a bit sceptical. Wallet movements can reflect custody operations, internal shuffling, or settlement flows, not just outright directional bets. So while Arkham's figures are a solid data point, they should be read alongside official ETF flow reports rather than treated as gospel in isolation.
Still, the broader conclusion holds up: institutions were net buyers last week, and that undercuts the more bearish take that traditional players are heading for the exits. [5]
For Bitcoin, steady positive ETF demand remains one of the cleanest structural supports in the market. Even modest net inflows can absorb a fair bit of sell pressure when they persist over time. A $93.1 million weekly inflow is not explosive, but in a choppy tape it is enough to keep the floor from looking completely dodgy.
The main thing to watch now is whether this buying continues if BTC pushes higher, or whether institutions only step in on dips. If flows stay positive into strength, that is a stronger confirmation of trend continuation. If they fade quickly, last week may prove to be little more than opportunistic bargain hunting.
Risk box
This move gets a lot less convincing if weekly ETF flows flip back to sustained net outflows, or if wallet tracking later shows the apparent accumulation was mostly custody reshuffling rather than fresh demand. For now, though, the read is straightforward: BlackRock and Fidelity added more Bitcoin than they sold last week, and that is still a proper positive for the BTC demand picture.
