Bitcoin ETF inflows hit $1.9B in strongest week since October 2025

US spot Bitcoin ETFs have demonstrated a remarkable turnaround, recording $1.92 billion in net inflows during the week ending Friday, August 23, 2026. This performance marks their strongest weekly showing since October 2025, according to SoSoValue data. The renewed demand for these investment products coincided with a significant price rally for Bitcoin, which climbed more than 20% last week, briefly touching above $79,000 after starting the week near $63,000. This influx suggests a potential shift in investor sentiment, moving away from the heavy outflows observed earlier in 2026.

$1.92 Billion

The recent $1.92 billion in net inflows represents a substantial injection of capital into the Bitcoin ETF market, signaling a strong return of investor interest. This figure is particularly noteworthy as it contrasts sharply with the preceding months, which saw significant outflows. For instance, June recorded the heaviest monthly outflows at $4.51 billion, followed by $2.43 billion in May. The current August inflows, totaling $2.38 billion through Friday, have already made it the strongest month for inflows this year, indicating a robust recovery in demand.

This renewed enthusiasm is not limited to Bitcoin alone; spot Ether ETFs also attracted approximately $700 million, with both Bitcoin and Ether funds experiencing their strongest weekly inflows since October 2025. The collective performance underscores a broader positive sentiment returning to the crypto ETF space, potentially driven by Bitcoin's price appreciation and broader market dynamics.

BlackRock’s IBIT

BlackRock’s iShares Bitcoin Trust ETF (IBIT) played a pivotal role in last week's resurgence, accounting for a significant portion of the total inflows. IBIT alone attracted about $1.33 billion in net inflows over five consecutive trading days. Its daily inflows showed a strong upward trend, rising from $160.2 million on Monday to $503 million on Thursday, before slightly easing to $239.3 million on Friday.

Bloomberg ETF analyst Eric Balchunas highlighted IBIT's daily flow pattern on X, describing it as a “classic Flipping the Bird pattern” and interpreting it as a bullish signal. This specific pattern, characterized by increasing inflows followed by a slight dip, is often seen by analysts as an indicator of sustained buying interest and positive market momentum for the asset. The strong performance of a major player like BlackRock's IBIT often sets a precedent and can influence other market participants.

October 2025

The article frequently references October 2025 as a benchmark for the current strong inflows. During that period, the funds attracted $3.42 billion, which was a significant inflow wave. However, the article also notes that the October 2025 inflows preceded a major crypto market crash on October 10, which triggered the largest liquidation event in the industry's history, wiping out roughly $19 billion in leveraged positions within 24 hours. Since October 6, 2025, when Bitcoin traded near $124,700, its price has plummeted approximately 38%.

This historical context serves as a crucial reminder that while strong inflows can signal positive sentiment, they do not guarantee sustained price appreciation and can sometimes precede periods of high volatility or market corrections. Investors are encouraged to conduct independent research, as all investments and trades carry inherent risks. The current inflows, while strong, are still being evaluated against the backdrop of past market events and the overall performance of Bitcoin ETFs in 2026, which remain in net outflows year-to-date.
