Bitcoin, Ethereum ETFs Post Biggest Inflow Week of 2026

Data compiled for the five trading sessions through Aug. 21 showed Bitcoin exchange-traded funds took in $1.918 billion and Ethereum funds $697.2 million, a combined $2.615 billion and the strongest weekly intake for the pair in about 10 months. Bitcoin funds recorded inflows every day during the week, raising cumulative net subscriptions since the ETFs’ January 2024 debut to $53.7 billion. The weekly total was the largest for Bitcoin ETFs since the market selloff in October 2025. Ethereum funds had their best week since early October 2025, when they drew nearly $1.3 billion.

Bitcoin rose from roughly $62,300 at the start of the week to trade near $80,000 on Friday, a gain of about 25% before a modest pullback. Ethereum climbed to above $2,500 before retreating. As of press time Bitcoin traded near $76,550 and Ethereum around $2,400.

On Aug. 19 the U.S. Treasury said it would double the maximum size of liquidity-support buybacks for 10- to 20-year and 20- to 30-year Treasuries to at least $4 billion per operation. Long-term yields fell after the announcement. A White House meeting with crypto executives was followed by comments from President Donald Trump that the U.S. was considering accumulating large amounts of Bitcoin and other cryptocurrencies; those comments did not create new authority for open-market purchases.

On Aug. 18 the Securities and Exchange Commission proposed a framework for crypto fundraising called Regulation Crypto Assets, including exemptions and a conditional safe harbor for qualifying token offerings. Two days later the Commodity Futures Trading Commission convened the first meeting of its Innovation Advisory Committee, attended by executives from major crypto firms.

Technical factors coincided with the inflows. Bitcoin reclaimed its 200-day moving average after earlier failing to hold above that trend line. The rapid price rise triggered the liquidation of billions of dollars of leveraged short positions. A Bitcoin-focused research platform reported ETF demand had been gradually recovering through August and surged in the final sessions when the technical breakout occurred; its flow model places Bitcoin in a supported range of roughly $67,000 to $78,000 with an estimated fair value near $72,000.

Market participants cautioned that a single strong week does not establish a lasting change in investor behavior. The next test for the ETFs will be whether subscriptions remain positive after Bitcoin’s roughly 25% weekly gain and once forced liquidation of bearish positions eases.
