Overview

• US spot Bitcoin ETFs took in about $1.18–$1.19 billion on Oct. 6, the second-largest single-day haul since launch, lifting October’s four-day total to roughly $3.47 billion.
• BlackRock’s iShares Bitcoin Trust led with roughly $967–$970 million in one day and is approaching $100 billion in AUM, with analysts noting it is now BlackRock’s most profitable ETF by fee revenue.
• Bitcoin touched an all-time high near $126,198 before easing toward $124,000, as ETF-led demand interacted with safe-haven flows tied to a U.S. government shutdown, a softer dollar and expectations for Fed easing.
• Spillover was broad: the total crypto market value topped $4.2 trillion, major altcoins advanced, and mining shares jumped, with Argo +96%, HIVE +25%+, Riot +10.9% and MARA +9.3%.
• Fragility signals are building, including record derivatives open interest, rising leverage on Binance and whale profit-taking, and prior $1B+ ETF inflow days have often preceded short-term local tops.
