The cryptocurrency market staged a strong rebound in the third week of August, lifting total market capitalization by $500 billion to a peak near $2.74 trillion, its highest level since early May. Bitcoin led the advance, rising from below $63,000, briefly trading above $79,000, and settling near $77,200, while ether traded around $2,423; both assets gained roughly 24% to 28% on the week, bitcoin’s largest weekly advance in two years. Institutional demand was central: U.S. spot bitcoin and ether ETFs recorded their strongest combined week since October 2025, drawing about $2.6 billion in net inflows and reversing a combined $392 million outflow from the prior week. Spot bitcoin ETFs alone took in about $1.9 billion, the largest weekly total since mid-October 2025, lifting cumulative net inflows since launch to $53.7 billion and net assets under management 25.4% to $96.1 billion on $22.1 billion of trading volume. Spot ether ETFs attracted $697.2 million, their best week since early October 2025, raising cumulative net inflows to $12.2 billion and net assets 35.9% to $14.3 billion. Combined year-to-date shortfalls narrowed from about $5.7 billion to $3.1 billion, though bitcoin ETFs remained down roughly $2.9 billion and ether ETFs about $191.8 million for 2026. Spot altcoin ETFs also saw inflows, while the advance remained volatile, with roughly $550 million in leveraged positions liquidated in 60 minutes and 24-hour liquidations reaching $1.8 billion.
