# Bitcoin ETFs see $463M outflow after 3-week inflow streak Ethereum ETFs continue positive trend with $197M inflow - **Source:** [INCRYPTED](https://brifing.si/source/7cd4625d-3f08-4cc1-983d-4c7d991839ba) - **Published:** 2026-09-12 - **Topic:** [Finance](https://brifing.si/c/finance) - **Original article:** - **On Brifing:** https://brifing.si/s/9afa6a08-84f8-46eb-abe3-5ba2fe4f5ea2 ## Bitcoin ETF outflow reversal Spot Bitcoin ETFs in the US recorded a $462.73 million outflow from September 8-11, 2026, ending three consecutive weeks of positive inflows. ARK Invest's ARKB saw the largest withdrawal at $234.24 million, followed by Grayscale's GBTC at $129.11 million. The outflow peaked on September 10 with $282.56 million withdrawn, though some funds like Morgan Stanley's MSBT attracted $19.65 million new capital during the same period. ## Daily breakdown of Bitcoin ETF flows The $463 million Bitcoin ETF outflow occurred across four trading days: $46.65 million on September 8, $120.24 million on September 9, $282.56 million on September 10 (the largest single-day outflow), and $13.29 million on September 11. BlackRock's IBIT lost $52.57 million, Fidelity's FBTC $50.6 million, while Bitwise's BITB managed a modest $1.91 million inflow. This reversal followed a $986.85 million inflow the previous week. ## Ethereum ETFs buck the trend While Bitcoin ETFs struggled, spot Ethereum ETFs attracted $197.11 million during the same September 8-11 period, marking their fourth consecutive week of inflows. BlackRock's ETHA led with $139.94 million inflow, followed by ETHB ($55.2 million) and ETHW ($29.09 million). The positive momentum was driven by a massive $216.41 million inflow on September 11 alone, offsetting smaller outflows earlier in the week. ## Altcoin ETF performance Among alternative cryptocurrency ETFs, XRP-focused funds led with $18.98 million inflows, followed by SOL-ETF ($10.3 million) and LINK-ETF ($5.36 million). However, HYPE-ETF saw the largest altcoin outflow at $26.42 million. Newly launched TRX-ETFs debuted on September 10 but recorded no capital movement, while Hong Kong's SOL-ETFs attracted 511.49 SOL tokens during the reporting period. ## Market impact of ETF flows The $463 million Bitcoin ETF outflow represents a significant shift in investor sentiment after weeks of positive momentum. ETF flows directly impact cryptocurrency prices as they require underlying asset purchases or sales. The contrasting performance between Bitcoin and Ethereum ETFs suggests diverging institutional confidence, with Ethereum maintaining steady demand despite Bitcoin's volatility. ## Major players' performance ARK Invest and Grayscale dominated Bitcoin ETF outflows, accounting for $363.35 million (78.5%) of the total $463 million withdrawal. BlackRock showed mixed results - its Bitcoin ETF (IBIT) lost $52.57 million while its Ethereum ETF (ETHA) gained $139.94 million. Fidelity's Bitcoin ETF (FBTC) saw $50.6 million outflow, and its Ethereum product (FETH) lost $3.87 million, highlighting different strategies among asset managers. ## Historical context The current outflow follows three weeks of Bitcoin ETF inflows totaling over $2 billion, with the previous week alone seeing $986.85 million. Ethereum ETFs have shown more consistent performance, with four straight weeks of inflows totaling approximately $600 million. These patterns reflect broader market trends where Ethereum has demonstrated more stability compared to Bitcoin's sharper fluctuations in institutional demand. ## Industry implications The ETF flow reversal underscores cryptocurrency markets' volatility even among institutional products. The simultaneous Bitcoin outflow and Ethereum inflow may signal a rotation between major digital assets rather than broad crypto market withdrawal. As more altcoin ETFs emerge, their smaller but growing flows (like XRP's $19 million gain) indicate expanding institutional interest beyond just the two largest cryptocurrencies. ## Sources covering this story - https://incrypted.com/bytkoyn-etf-prervaly-trekhnedelnuyu-seryyu-prytokov-kapytala-ottokom-na-463-mln/ — --- _Summary written by Brifing from the original reporting.
