Bitcoin ETPs Now Control 1.47M BTC, 7% of Total Supply

Highlights:

• Bitcoin ETPs now manage 1.47 million BTC, capturing nearly 7% of supply.
• US-based spot ETFs lead with dominance, BlackRock IBIT topping at 746,810 BTC.
• Fidelity FBTC and Grayscale GBTC strengthen positions with sizable BTC allocations.

Bitcoin-related exchange-traded products (ETPs) now collectively control close to 1.5 million BTC, representing about 7% of Bitcoin’s capped supply. Wealth management expert Nate Geraci highlighted this milestone, pointing to the growing influence of Bitcoin funds on the market. Latest figures reveal that by late August, Bitcoin spot ETFs and other ETPs collectively held 1,474,606 BTC.

US Spot Bitcoin ETFs Hold Majority Share With BlackRock Leading the Market

Most of these holdings come from the United States, where spot ETFs dominate the market. Out of all ETPs, U.S.-based spot ETFs alone account for nearly 87.56% of the stash, equal to about 1.29 million BTC. BlackRock’s iShares Bitcoin Trust (IBIT) leads the pack with 746,810 BTC, while Fidelity Wise Origin Bitcoin Fund (FBTC) follows with 199,497 BTC, and Grayscale Bitcoin Trust ETF (GBTC) holds 178,728 BTC.

Beyond the leading three funds, no other spot Bitcoin ETF or ETP has managed to secure more than 50,000 BTC in assets. Close contenders include ARK 21Shares Bitcoin ETF (ARKB) with 43,054 BTC, Bitwise Bitcoin ETF (BITB) holding 40,636 BTC, and Grayscale Bitcoin Mini Trust ETF (BTC) managing 46,520 BTC. On the opposite end, WisdomTree’s BTCW holds the smallest amount, with just 1,591 BTC under management in the U.S. market.

The influence of U.S. spot Bitcoin ETFs is even clearer when looking at the global rankings. U.S. products dominate the rankings, securing the first six spots among the top ten Bitcoin ETPs by assets under management. VanEck’s HODL manages to take the eighth position, which leaves only three remaining places for non-U.S. offerings. 

Bitcoin Whales Shift Billions to Ethereum

At the same time, interest in Bitcoin ETFs and ETPs has weakened in recent weeks as more institutional attention shifts toward Ether-based products. On Monday, one notable whale offloaded 4,000 BTC in exchange for 96,859 ETH within just 12 hours. Following the swap, this single whale’s Ether holdings have grown to a massive $3.8 billion. According to blockchain intelligence firm Arkham, the move is part of a broader trend. 

Data released on Wednesday revealed that nine separate whales have locked in profits from Bitcoin and redirected their capital into Ether. Together, their ETH purchases total approximately $456 million. This weakening in Bitcoin momentum is unfolding against a backdrop where September has traditionally been one of its poorest-performing months. Meanwhile, gold prices have been climbing, adding another layer of pressure on the flagship cryptocurrency.

Another reason investors may be holding back from betting on Bitcoin is the 92 crypto-related ETFs still pending with the US Securities and Exchange Commission. Among them are some of the most-anticipated funds, including those tracking Solana (SOL) and XRP, which are set for regulatory decisions in October. Delphi Digital said Bitcoin could rise then fall after Fed rate cuts. They added that prices may stay steady if demand remains low.

How will rate cuts affect BTC?

• 2019 established a 'sell the news' precedent for rate cuts.
• Last year, ETF inflows fueled a sustained rally after rate cuts.
• This makes the upcoming rate cut a conditional setup rather than a straightforward catalyst.
