Spot Bitcoin ETFs See Strongest Weekly Inflows Since April Amid Low Trading Volume

U.S. crypto funds recorded their strongest combined weekly inflows since April, with spot Bitcoin products drawing $853.5 million across five straight positive trading days. Ether ETF inflows added $244.9 million during the same period, bringing the combined total to $1.1 billion.

BlackRock's IBIT captured the majority of Bitcoin demand, absorbing $693.7 million—more than 80% of weekly Bitcoin ETF inflows. Fidelity's FBTC ranked second with $116.4 million, roughly 13% of the total. Daily inflows peaked on Wednesday at $244.4 million, followed by Tuesday's $211.5 million. Thursday and Friday were weaker, contributing $128.7 million and $98.9 million respectively.

Bloomberg analyst Eric Balchunas attributed some buying activity to the Coldcard wallet exploit, which affected certain Bitcoin cold-storage devices and resulted in reported thefts exceeding $111 million. Several major funds recorded inflows each day following the vulnerability's disclosure. However, the article notes this narrative has limitations: Ether ETF inflows also posted their best week since April, extending their winning streak to five weeks—the longest streak in 2026. Since Ether holders had no exposure to a Bitcoin-only hardware wallet issue, this suggests institutional demand extends beyond the exploit.

Bitcoin rose approximately 3% during the week and moved above $65,300 on Friday. U.S. payrolls fell by 23,000 in July, missing forecasts for an 80,000 increase and prompting traders to reduce expectations for a September Federal Reserve rate hike. Yet most Bitcoin ETF inflows arrived before Friday's labor data, indicating institutional buying was already underway before the macroeconomic report.
