BlackRock's spot Bitcoin exchange-traded fund (ETF) has surpassed Grayscale Bitcoin Trust (GBTC) as the largest ETF tracking Bitcoin's price, marking a significant milestone in the cryptocurrency market ¹. This shift in leadership comes as BlackRock's iShares Bitcoin Trust (IBIT) recorded a substantial inflow of $102.5 million, while GBTC experienced a $105 million outflow, according to data from HODL15Capital and the Apollo Bitcoin Tracker.

As of May 28, BlackRock's spot Bitcoin ETF holds a total of 288,670 Bitcoin, valued at $68,559, surpassing Grayscale's current holdings of 287,450 Bitcoin. Notably, Grayscale's holdings have decreased significantly from its initial 620,000 Bitcoin at the time of its conversion in January. This development is a testament to the growing popularity of BlackRock's ETF among investors.

According to a May 29 report from Bloomberg, BlackRock's fund holds $19.68 billion of Bitcoin, closely followed by Grayscale's $19.65 billion. Fidelity's ETF offering trails at $11.1 billion, indicating a significant gap between the top two players in the market. HODL15Capital aptly described the situation, stating, "There is a new king in the land of Bitcoin ETFs & its BlackRock."

Both BlackRock's and Grayscale's ETFs launched on the same day in January, but BlackRock's ETF has dominated the market, accounting for the majority of inflows across all 11 spot Bitcoin ETFs. Bitcoin's price has also seen a 1.1% increase, currently standing at $68,550, according to CoinMarketCap data.

Recent regulatory filings reveal that BlackRock's income and bond-focused funds have invested in its spot Bitcoin ETF. The Strategic Income Opportunities Fund (BSIIX) purchased $3.56 million worth of IBIT, while the Strategic Global Bond Fund (MAWIX) acquired $485,000. These investments, disclosed in May 28 Securities and Exchange Commission filings, demonstrate the growing interest in cryptocurrency among traditional investors.

The cumulative holdings of spot Bitcoin ETFs globally have surpassed one million Bitcoin, valued at over $68 billion. This represents nearly 5.10% of the total Bitcoin circulating supply, indicating a significant increase in mainstream adoption. As the cryptocurrency market continues to evolve, all eyes are on the potential launch of spot Ether ETFs, which analysts predict could occur as early as mid-June.

The approval of spot Bitcoin ETFs has paved the way for other cryptocurrencies like Ethereum to follow suit. Ethereum, the largest cryptocurrency by market capitalization after Bitcoin, has a decentralized open-source blockchain platform that enables the creation of decentralized applications and smart contracts. The potential launch of spot Ether ETFs is undergoing an S-1 approval process, the final hurdle before trading on stock exchanges can begin.

In conclusion, BlackRock's spot Bitcoin ETF surpassing Grayscale marks a historic turning point in the cryptocurrency market. As the market continues to grow and mature, it is likely that we will see increased mainstream adoption and further developments in the cryptocurrency space. The potential launch of spot Ether ETFs and the growing interest in cryptocurrency among traditional investors are testaments to the evolving landscape of digital assets.
