The cryptocurrency market has just reached a major turning point, marked by exceptional activity in US-based exchange-traded funds (ETFs). On September 21, 2026, the 12 spot Bitcoin ETFs recorded a historic net inflow of $999 million. This performance, the highest since October 2025, marks a sharp break from the bearish trend observed during the first half of the month, when capital outflows had dampened investor sentiment following legislative setbacks in the Senate.
At the heart of this momentum, asset management giants are reaffirming their dominance. The iShares ETF by BlackRock captured the lion's share with $381.4 million, followed by products from ARK Invest and Fidelity. This institutional enthusiasm is not limited to Bitcoin: Ethereum-based ETFs also recorded a remarkable performance of $270 million in a single day, their best result in eleven months, once again fueled by investment solutions from BlackRock and Fidelity.
This massive return of institutional investors comes amid a significant technical market rebound. The price of Bitcoin crossed the $87,000 mark, triggering a wave of short squeezes that intensified buying pressure. Over $1 billion in positions were liquidated on trading platforms in just 24 hours, confirming speculators' jitters in the face of this sudden resurgence in risk appetite.
Financial analysts point out that this renewed interest is supported by a convergence of favorable macroeconomic factors. Easing US bond yields, falling oil prices, and the international diplomatic climate have created a perfect backdrop for capital to flow back into digital assets. This record-breaking streak erases the losses accumulated in September and places crypto funds back at the center of attention, signaling renewed confidence in the medium-term bullish trajectory of these assets.
