Bitcoin ETFs Flip From $426M Outflow to $6M Weekly Inflow

U.S. crypto exchange‑traded funds (ETFs) experienced sharp swings during the week of September 16‑20, 2026. After a mid‑week wave of redemptions driven by policy news, inflows surged on Friday, turning a $426 million outflow into a modest $6.21 million net gain for Bitcoin ETFs.

Mid‑Week Outflows Triggered by Policy Events

Monday saw $160.04 million flow into Bitcoin funds, but Tuesday’s $450.33 million withdrawal followed the Senate’s failed cloture vote on the Digital Asset Market Clarity Act. Wednesday added another $295.98 million exit as the Federal Reserve raised rates by 25 basis points to a range of 3.75‑4 % – its first hike since July 2023. A Thursday rebound of $159.45 million set the stage for Friday’s reversal.

Friday Rebound Restores Positive Flow

On Friday, investors poured $433.03 million into Bitcoin ETFs, pushing the weekly total to a $6.21 million net inflow. The surge was led by BlackRock’s iShares Bitcoin Trust (IBIT) with $120.66 million, Fidelity’s FBTC with $79.9 million, and Morgan Stanley’s MSBT with $13.2 million. Ark & 21Shares’ ARKB recorded the largest weekly outflow at $141.9 million, while Grayscale’s GBTC lost $62.3 million.

Ether ETFs Reverse Four‑Week Gains

Ether‑linked ETFs posted $140 million in net outflows, ending a four‑week streak of inflows. Withdrawals of $141.47 million on Tuesday and $224.11 million on Wednesday outweighed Monday’s $121.02 million inflow. Friday’s $143.80 million inflow provided limited relief, and Ether’s price briefly rose above $2,700.

Smaller Crypto ETFs Show Mixed Results

• Zcash (ZEC) ETFs attracted $98.21 million, driven by Grayscale’s ZCSH.
• XRP ETFs recorded $9.56 million net inflows.
• HYPE ETFs ended with $3.06 million net inflow after a Tuesday withdrawal.
• Solana ETFs saw strong activity, including $47.62 million on Friday.

Outlook

The week’s pattern suggests rapid repositioning around policy developments rather than a sustained retreat. Continued ETF demand in the coming week will indicate whether institutional allocations are aligning with the recent price rebound in Bitcoin, which reclaimed the $80,000 level after ETF markets closed.
