Spot Bitcoin ETFs Snap 4-Week Outflow Streak With $70M Inflows as Analysts Eye Potential Bottom
Introduction
In a significant shift for digital asset markets, U.S. spot Bitcoin exchange-traded funds (ETFs) have broken a persistent negative trend, posting approximately $70 million in net weekly inflows after enduring four consecutive weeks of substantial withdrawals. This reversal comes after a challenging period that saw roughly $4.35 billion exit the sector, dramatically reducing net assets. Simultaneously, spot Ether ETFs mirrored this positive momentum, recording $312.6 million in net weekly inflows following their own three-week outflow streak. The turnaround has captured analyst attention, with some suggesting Bitcoin may be approaching a technical bottom as market indicators show potential for recovery. This development marks a crucial test for the fledgling ETF products that have revolutionized institutional crypto access since their landmark approvals earlier this year.
The Bleak Precedent: Four Weeks of Sustained Outflows
The recent $70 million inflow gain stands in stark contrast to the preceding month's performance. According to data from SoSoValue, spot Bitcoin ETFs experienced four straight weeks of heavy outflows that collectively drained approximately $4.35 billion from the sector. The most severe withdrawal periods occurred during the weeks ending November 7 and November 21, 2025, with each week witnessing $1.22 billion exiting spot Bitcoin ETFs.
This extended outflow period represented one of the most significant challenges for the products since their launch, pushing net assets substantially lower and testing investor confidence in Bitcoin's near-term price prospects. The consistent withdrawals reflected broader market uncertainty and profit-taking behavior amid fluctuating cryptocurrency valuations. The magnitude of these outflows highlighted how quickly sentiment could shift even for products that had previously demonstrated remarkable resilience and accumulation patterns.
Daily Breakdown: Friday's Reversal and Fund-Specific Flows
The weekly turnaround was anchored by positive daily flows, particularly on Friday when Bitcoin funds registered approximately $71 million in net inflows. This daily performance lifted cumulative inflows since launch to nearly $57.7 billion while increasing combined net assets to approximately $119.4 billion. These assets now represent around 6.5% of Bitcoin's total market capitalization, underscoring the growing significance of ETF vehicles within the broader crypto ecosystem.
Interestingly, Friday's positive net flow occurred despite BlackRock's IBIT experiencing $113.7 million in daily outflows. This was more than offset by robust inflows into competing products, with Fidelity's FBTC attracting $77.5 million and ARK 21Shares' ARKB drawing $88 million. This fund-specific divergence suggests that while overall sentiment improved, investor preferences among the various ETF offerings continued to evolve, with some products demonstrating stronger appeal during the recovery phase than others.
Ether ETFs Join the Rebound: Breaking Three-Week Outflow Streak
The positive momentum extended beyond Bitcoin products, with spot Ether ETFs staging their own notable turnaround. After three consecutive weeks of heavy withdrawals that drained roughly $1.74 billion from Ether ETFs, the sector recorded $312.6 million in net weekly inflows. The most challenging period during this outflow streak was the week ending November 14, 2025, when investors pulled $728.6 million from Ether products.
On Friday, Ether ETFs posted approximately $76.6 million in inflows, pushing cumulative net inflows since launch to $12.94 billion. Total assets across U.S. spot Ether ETFs now stand near $19.15 billion, equivalent to around 5.2% of Ether's market capitalization. The parallel recovery in both Bitcoin and Ether ETF flows suggests a broader improvement in sentiment toward digital asset investment products rather than a cryptocurrency-specific phenomenon.
Analyst Perspectives: Technical Indicators Suggest Potential Bottom Formation
The flow reversal has coincided with emerging analyst views that Bitcoin may be forming a short-term bottom. As Cointelegraph reported, trader Mister Crypto has indicated that Bitcoin could have established a technical bottom as the Relative Strength Index (RSI) approaches oversold levels and whales reopen long positions. This combination, according to his analysis, raises the odds of a relief rally toward the $100,000–$110,000 range.
Adding to this perspective, Bitwise Europe research head André Dragosch has stated that Bitcoin could have major upside ahead, arguing that its current price doesn't fully reflect improving macro expectations. These technical and fundamental assessments provide context for the ETF flow reversal, suggesting that sophisticated market participants may be positioning for a potential recovery phase after weeks of downward pressure and outflows.
Comparative Context: ETF Performance Since Launch
The recent volatility highlights the evolving nature of these relatively new investment products. Since their launch, spot Bitcoin ETFs have accumulated nearly $57.7 billion in net inflows despite periodic withdrawal phases. Their combined net assets of approximately $119.4 billion represent a significant achievement for products that didn't exist a year ago. Similarly, Ether ETFs have gathered $12.94 billion in cumulative inflows since their debut, building to $19.15 billion in total assets.
The current assets under management for Bitcoin ETFs equate to about 6.5% of Bitcoin's total market capitalization, while Ether ETFs represent approximately 5.2% of Ether's market cap. These percentages demonstrate the substantial institutional footprint these products have established in a relatively short timeframe, though they also indicate significant room for future growth as adoption continues.
Broader Market Implications and What to Watch Next
The simultaneous reversal in both Bitcoin and Ether ETF flows after extended outflow periods represents a potentially significant inflection point for digital asset markets. While a single week of positive flows doesn't necessarily establish a definitive trend reversal, the combination of technical indicators suggesting oversold conditions, renewed institutional interest, and improving macro expectations creates a compelling narrative for cautious optimism.
Market participants should monitor whether this inflow pattern sustains through coming weeks, particularly watching for consistency across both major cryptocurrency ETF categories. The performance divergence between specific funds like BlackRock's IBIT versus Fidelity's FBTC and ARK 21Shares' ARKB also warrants attention as it may signal evolving investor preferences among ETF providers. Additionally, continued observation of technical indicators like RSI levels and whale accumulation patterns will help validate whether the potential bottom formation thesis gains further support.
The coming weeks will prove critical in determining whether this inflow reversal represents merely a temporary pause in outflows or the beginning of a more sustained accumulation phase. Either way, the data demonstrates that these ETF products have become essential barometers for institutional sentiment toward digital assets, providing transparent, real-time indicators of capital flows that were largely inaccessible to market observers before their introduction.
