Spot Bitcoin exchange-traded funds (ETFs) are experiencing one of their strongest months since launching in January 2024, with inflows surpassing $3 billion so far in October.This surge in demand has led ETF issuers to purchase Bitcoin at levels far exceeding the newly mined supply.
US Spot Bitcoin ETFs Amass 45,000 BTC in October
During the trading week of October 21-25, the 11 spot Bitcoin ETFs bought a combined 15,194 BTC, which is nearly five times the 3,150 BTC mined in that period, according to data from HODL15Capital. Inflows during this week totaled around $1.83 billion, reflecting the strong demand that has fueled unprecedented levels of BTC acquisition by ETF issuers.

Bitcoin ETFs, these issuers have collectively purchased 45,557 BTC. This is the fourth-highest month for BTC acquisitions since spot ETFs received approval on January 10, 2024.Meanwhile, aggressive buying has brought ETF issuers’ combined BTC holdings close to one million BTC. As of October 25, the Bitcoin ETF issuers collectively held 977,122 BTC — just 22,878 BTC short of the million-BTC threshold. BlackRock has the largest BTC reserve, holding approximately 403,714 BTC, which equates to nearly 2% of Bitcoin’s total supply.

Notably, if the ETFs’ current accumulation rate continues, their combined holdings could soon surpass that of Satoshi Nakamoto, the pseudonymous creator of the top asset.
Not yet 10mo old and the ETFs are 97% of the way to holding 1 million btc, and 87% of the way to passing Satoshi as biggest. I’ll be presenting on this and much more at the Plan B conf in Lugano tmrw (10am, main stage). If you’re going, come say hi https://t.co/5NmhFANOpu

Market observers have pointed out that with the ETF issuers now holding a substantial portion of BTC’s supply, their influence on market liquidity and price stability is likely to grow.Indeed, as the ETFs continue accumulating the top asset, there may be greater volatility risk during periods of high inflows or outflows, particularly given the relatively fixed supply of BTC. Analysts caution that such concentration could lead to increased price sensitivity in response to market dynamics.More By This Author:WMA: Bitcoin Drops To $67,000 After Turbulent Week For The Market
