Bitcoin and Ethereum spot ETFs recorded the largest weekly inflows of 2026, with Bitcoin ETFs drawing $1.918 billion and Ethereum ETFs $697.2 million, for a combined $2.6 billion, according to SoSoValue data. The inflows occurred during a rally that pushed Bitcoin from roughly $62,300 to near $80,000 and Ethereum to a seven‑month high above $2,500 before prices pulled back to about $76,550 and $2,400 respectively, as reported by CryptoSlate. The rally was driven by falling Treasury yields, a Treasury announcement to expand liquidity‑support buybacks for long‑term securities, and comments from President Donald Trump indicating the administration may increase government holdings of Bitcoin and other cryptocurrencies, according to public statements. Regulatory momentum also grew: the SEC proposed the Regulation Crypto Assets framework on August 18, the first tailored rule for crypto fundraising, and the CFTC held the inaugural meeting of its Innovation Advisory Committee, which included executives from Coinbase, Uniswap Labs and BitGo, as noted in agency statements. ETF demand had been recovering gradually in August, but accelerated in the final days of the week as Bitcoin reclaimed its 200‑day moving average and billions of dollars of leveraged short positions were liquidated, according to Ecoinometrics. Analysts say that continued ETF inflows could support Bitcoin in a range of $67,000 to $78,000, with a fair value near $72,000, and that sustained demand may attract trend‑following investors, though one strong week does not guarantee a lasting market shift.
