Bitcoin Trades Near $84,400 on September 25, Up 3.4% for the Week, as US Spot ETF Inflows Swing from Minus $5.8 Billion to Plus $800 Million Year-to-Date

Bitcoin opened at $84,378 on Friday, September 25, 2026, and lifted to $85,200 by 7:14 AM ET, according to Yahoo Finance, capping a roughly 3.4% weekly gain and its best quarter since late 2024 with a 44% rise after three straight quarters of losses. The rally has been matched by a sharp reversal in institutional demand: US spot Bitcoin ETFs have swung from being down $5.8 billion for the year in July to nearly $800 million in net inflows now, powered partly by a six-day streak that pulled in $2.84 billion, according to Nexo research published September 25. The backdrop remains genuinely tense. The 10-year Treasury yield touched 5.225% this week, its highest level since July 2007, while the 30-year climbed to its highest since 2004, according to Nexo and Yahoo Finance. Bitcoin's market capitalization stands at roughly $1.33 trillion, far ahead of second-place Ethereum at about $233 billion in market cap, according to Fortune. Ethereum opened at $2,687 on Friday, up 0.1% from Thursday, and moved to $2,738 by morning. This matters because Bitcoin's behavior in the current environment tests two competing narratives. The ETF base has clearly turned a corner, suggesting renewed institutional conviction even as bond markets signal more stress than crypto's own pricing currently reflects, according to Nexo. Next week brings a dense run of data that could reset the picture: the Reserve Bank of Australia rate decision, US consumer confidence, JOLTS job openings, core PCE (the Fed's preferred inflation gauge), ISM and S&P Global manufacturing PMIs, and Friday's September jobs report all land between Tuesday and Friday, according to Nexo. For crypto, the setup remains genuinely two-sided: an institutional bid that has reversed sharply in the past two months, against a bond market signaling more persistent inflation and higher-for-longer rates than Bitcoin's current near-all-time-high pricing appears to discount.
