Summary
Bitcoin spot exchange-traded funds continued their multi-day rally on September 29, 2026, attracting $31.07 million in net inflows and extending a positive streak to eight consecutive trading sessions. This sustained inflow pattern reflects persistent institutional interest in spot Bitcoin exposure through regulated ETF vehicles, a structural shift that has redefined cryptocurrency market dynamics since the approval of these products.
The broader US spot crypto ETF complex showed mixed momentum during the same period. Combined inflows across Bitcoin, Ethereum, Solana, and XRP spot ETFs totaled $64.8 million on Monday, though this figure represented an approximately 80% sequential decline from Friday's performance. Ethereum ETFs contributed $17.1 million to the day's total, with Ether trading at $1,919 and appreciating 1.99%. This pullback suggests some rotation or profit-taking activity, despite the continuation of positive inflows across the sector.
On a weekly basis, Bitcoin spot ETFs demonstrated stronger aggregate momentum, accumulating approximately $865 million in net inflows. This weekly metric provides important context for interpreting daily volatility; while individual trading sessions show pronounced fluctuations, the underlying weekly accumulation indicates sustained institutional capital deployment into spot Bitcoin products.
The extension of Bitcoin's eight-day inflow streak reflects a broader pattern of capital attraction into regulated cryptocurrency investment vehicles, even as daily inflow rates compress from peak levels. For institutional investors and family offices evaluating exposure to digital assets, the persistence of multi-session inflows—combined with weekly aggregates exceeding $800 million—suggests meaningful conviction among market participants despite near-term price volatility and daily flow variability.
