US Bitcoin ETFs add $786M, biggest weekly inflow since February
US Bitcoin ETFs posted their biggest weekly net inflow since February, with more than $786 million added last week (SoSoValue). The total was slightly below the roughly $787.31 million seen in the final week of February.
Flows were choppy. Monday saw about $471.32 million of inflow, followed by midweek outflows, then a rebound on Thursday and Friday. The result was the strongest weekly performance for the category in nearly two months, aligning with renewed BTC momentum.
BlackRock’s iShares Bitcoin Trust (IBIT) led the demand, contributing around $612 million—nearly four-fifths of all US Bitcoin ETFs net inflows. Morgan Stanley’s newly launched MSBT added about $46 million over its first three trading days. While smaller, the launch matters due to Morgan Stanley’s distribution footprint of roughly 16,000 advisers.
The ETF turnaround matched a strong BTC week. Bitcoin rose from about $67,000 to above $70,000 and ended near $73,411, up roughly 9%.
For traders, the key read-through is improving institutional bid: US Bitcoin ETFs are re-accelerating after a quieter stretch, with heavy concentration in IBIT and incremental reach from newer issuers like MSBT.
Bullish
US Bitcoin ETFs saw a renewed, concentrated bid—nearly $786M net inflow since February’s peak—with BlackRock’s IBIT accounting for most of the flow. That kind of persistent inflow typically supports near-term BTC demand and can reduce sell-side pressure when price is already firm.
The week’s volatile path (Monday inflows, midweek outflows, then a rebound) suggests traders rotated risk as BTC stabilized and trended higher rather than chasing immediately. Still, the final week position remained the category’s best in nearly two months, which is consistent with a shift back toward institutional accumulation.
The MSBT launch adds a secondary catalyst: even if flows are smaller initially, Morgan Stanley’s large adviser network can broaden future access and potentially smooth inflow variability over time.
Overall, the combination of improving US Bitcoin ETFs inflows and a +9% BTC week points to supportive conditions for BTC in both the short term (continuation of institutional buying) and the medium term (more stable ETF demand as new distribution channels come online).
