Bitcoin ETFs resume inflows after a single red day; ether funds run to 11 straight

U.S. spot bitcoin ETFs pulled in roughly $217 million on Monday, Sept. 1, restarting inflows a session after about $202 million left the funds on Friday, CoinDesk reported, citing data from SoSoValue. Friday's outflow snapped a nine-day buying run dating to Aug. 19 — which had matched the longest inflow streak of 2026.

Ether ETFs never paused. Monday's $88 million net inflow was their 11th consecutive day of buying, worth $1.6 billion over the stretch, per SoSoValue via CoinDesk. That is the longest run for the ether products since a 20-day streak that ended in July 2025.

On the bitcoin side, net assets closed August just under $100 billion, having crossed above that mark on Aug. 27 before Friday's selling pulled them back below it. Cumulative net inflows since the funds launched in January 2024 stand near $55 billion, according to the same data. August was the strongest month of 2026 for bitcoin ETFs by a wide margin — more than double April's total — yet the funds still carry a net outflow of roughly $2.5 billion for the year to date.

CoinDesk tied Friday's single down day to rate-hike expectations rising after Federal Reserve Governor Kevin Warsh's remarks at Jackson Hole. Monday's rebound, the outlet noted, suggests allocators read Friday as a one-session adjustment rather than a turn — a reading this week's flow prints will test.

Key facts

• Bitcoin ETF net inflows Monday, Sept. 1: ~$217 million (SoSoValue, via CoinDesk).
• Friday's bitcoin ETF outflow: ~$202 million, ending a nine-day inflow run from Aug. 19 (SoSoValue/CoinDesk).
• Ether ETF inflows Monday: $88 million; 11th straight day, $1.6 billion total (SoSoValue/CoinDesk).
• Bitcoin ETF net assets: just under $100 billion at end of August, after topping $100B on Aug. 27 (CoinDesk).
• Cumulative bitcoin ETF net inflows since Jan. 2024 launch: ~$55 billion; 2026 year-to-date still ~$2.5 billion net outflow (CoinDesk).

The real-world read

These are one- and two-day flow figures, and daily ETF numbers get revised — treat single prints as noise, not signal. The framing worth watching: August being the "strongest month of 2026" sits alongside the funds still running a $2.5 billion net outflow for the year, so a strong month is a rebound from a hole, not a breakout. The Warsh-to-outflow link is CoinDesk's inference about allocator behavior, not a stated cause; no fund manager attributed the selling to Jackson Hole. And all of the above traces to a single secondary source relaying one data vendor, SoSoValue — no primary issuer filings or independent flow trackers are cited here to corroborate the totals.

Opinion, and whose

CoinDesk characterized Monday's rebound as allocators treating Friday as "a one-session adjustment rather than the start of a reversal," while noting this week's data will decide which reading holds. That is the outlet's interpretation, not a confirmed market view.
