Morgan Stanley’s New York-based MSBT Bitcoin ETF bought $51.5 million of Bitcoin over 20 trading days without a single day of outflows, according to Arkham. That figure differs from earlier on-chain reporting of roughly 642 BTC worth about $50.6 million transferred from Coinbase Prime over approximately two weeks in September 2026. MSBT has attracted more than $538 million in cumulative net inflows and reached between $586 million and $635 million in net assets by mid-September. Spot Bitcoin ETFs added $433 million in net inflows on Friday, led by Fidelity’s FBTC with $311 million and BlackRock’s IBIT with $108 million, while Ethereum ETFs recorded $144 million of inflows on Sept. 18. Bitcoin rose 3.86% over 24 hours to $81,234 and 5.04% over the week after a Federal Reserve rate cut, with the token briefly reaching $81,720. Glassnode said market demand remained strong, with entity-adjusted SOPR above 1 and Bitcoin back above the True Market Mean. Analysts are watching resistance near $80,000, the corporate treasury cost basis, $85,000, the ETF cost basis, and a liquidation cluster around $83,000-$86,000.
