Key Takeaways
- • Bitcoin spot ETFs accumulated $2.8 billion in net inflows over six consecutive trading days ending September 25, 2026, with Monday's single-day inflow of nearly $1 billion marking the largest since October 6 when Bitcoin reached an all-time high of $126,080.
- • Major asset managers including BlackRock, Fidelity, and Morgan Stanley are capturing institutional capital, with the average ETF buyer now in profit as the estimated cost basis surged above $81,720 for the first time since January 2026.
- • Bitcoin's price reached $87,330 on Monday before settling near $83,975 on Friday, representing a 4% weekly gain despite headwinds including failed crypto legislation (the Clarity Act) and Federal Reserve rate hikes.
- • CryptoQuant's analysis indicates Bitcoin has crossed above its 365-day moving average, signaling the asset has exited bear market territory and entered a potential bull run phase.
- • Renewed institutional interest follows the U.S. Department of the Treasury's August 2026 announcement to double liquidity-support buyback operations, a move that initially weakened the dollar and pressured long-duration yields, though Treasury yields have since reversed higher.
Summary
Bitcoin spot exchange-traded funds are sustaining momentum with a six-day winning streak of inflows totaling $2.8 billion as of September 25, 2026. According to Farside Investors data, the streak reflects consistent institutional capital deployment into funds managed by BlackRock, Fidelity, and Morgan Stanley. Monday's inflow reached nearly $1 billion—the largest daily intake since October 6, when Bitcoin briefly achieved an all-time high of $126,080 and the same funds received $1.2 billion in a single session.
Despite the robust inflow activity, Bitcoin's price trajectory has moderated. After peaking at $87,330 on Monday, the cryptocurrency settled near $83,975 by Friday, posting a more modest 4% weekly gain. However, Bloomberg ETF analyst James Seyffart highlighted a significant technical milestone: the average cost basis for ETF buyers has surged above $81,720 for the first time since January, placing the typical investor position in profitability.
The resurgence in institutional Bitcoin demand appears linked to macroeconomic policy shifts. In August 2026, the U.S. Department of the Treasury announced it would at least double the size of liquidity-support buyback operations, a measure that initially compressed 30-year Treasury yields and weakened the U.S. dollar—dynamics generally supportive of hard assets like Bitcoin. U.S. Treasury yields have since rebounded, though the policy backdrop has maintained investor interest in alternative assets.
Bitcoin demonstrated resilience last week despite two significant headwinds: lawmakers blocked the Clarity Act, a landmark piece of crypto legislation, and the Federal Reserve executed an interest-rate increase. Rather than triggering capitulation, these events coincided with sustained inflows into spot Bitcoin ETFs. CryptoQuant's market analysis released this week noted that Bitcoin has crossed above its 365-day moving average—a technical signal indicating the asset has transitioned out of bear market conditions. This development, combined with six consecutive days of ETF inflows and positive average cost basis dynamics, has prompted some market analysts to characterize the current environment as a nascent bull run phase.
