U.S. Bitcoin ETFs Record $1.28 Billion Weekly Outflow

The 12 U.S. spot Bitcoin ETFs registered $1.28 billion in net outflows last week, their largest weekly outflow since the week ended June 26 and their seventh-largest since trading began in January 2024.

Reported ETF flow data left 2026 net flows at negative $914.1 million after Friday’s session. The weekly result was also the funds’ weakest performance since late June. It erased the year’s earlier inflows and pushed the 12-fund complex into negative cumulative territory.

What was the daily pattern?

Net outflows occurred on four of five trading days, and Wednesday was the only session with a net inflow. The daily sequence was:

• Monday: $398.6 million net outflow
• Tuesday: $115.6 million net outflow
• Wednesday: $74.6 million net inflow
• Thursday: $430.2 million net outflow
• Friday: $411.9 million net outflow

Thursday’s $430.2 million was the largest single-session outflow in the week. The outflow then resumed on Thursday and Friday after Wednesday’s $74.6 million inflow.

How does the week compare with prior results?

The latest week followed a $202.6 million net outflow in the previous week. It remained below the $1.79 billion lost during the week ended June 26, which was the most recent larger weekly outflow.

The shift from $202.6 million to $1.28 billion marks a substantial week-over-week increase in net withdrawals. Net flow combines investor subscriptions and redemptions, so the figure indicates that withdrawals exceeded additions across the 12 funds.

How should the two headline figures be read?

The $1.28 billion figure covers last week alone. The $914.1 million figure covers 2026 through Friday, so they describe separate periods. The weekly figure captures the reversal from earlier net inflows to net outflows; the year-to-date figure shows the resulting cumulative position.

What happened to the funds’ assets?

The ETFs’ combined net asset value fell 2.3% during the week to $95.9 billion. That total was equivalent to about 6.3% of Bitcoin’s total market capitalization.

A $1.28 billion net outflow does not mean the funds’ entire $95.9 billion asset base disappeared. The outflow records net investor withdrawals, while net asset value also reflects valuation changes in the underlying Bitcoin holdings.

The available data are aggregated across all 12 funds and do not show a fund-level split. Investors therefore cannot determine from these figures alone which products generated most of the outflows.

What changed in 2026?

Before last week, the funds had attracted about $368 million in net inflows during 2026. Friday’s figures left year-to-date flows at negative $914.1 million, turning that earlier surplus into a deficit.

That reversal shows how quickly a change in investor allocations can overwhelm a small positive year-to-date balance. Even after the reversal, the ETFs reported $95.9 billion in combined net assets, equal to roughly 6.3% of Bitcoin’s market capitalization.

The key operational distinction is that subscriptions and redemptions determine net flow, while Bitcoin valuation changes affect net asset value even when no investor transaction occurs.

What does the next weekly update show?

The next weekly flow update will show whether the four-session outflow pattern persists and whether the 12 funds can rebuild from negative $914.1 million in year-to-date flows. Until fund-level figures or a sustained run of weekly inflows appears, the aggregate data will not identify which products drove the reversal.
