Hedge Funds and Wall Street Firms Follow Suit

The momentum around BlackRock’s IBIT isn’t limited to pension and sovereign funds. Hedge funds and Wall Street giants have also increased their exposure.

Millennium Management revealed in its latest SEC 13F filing that it holds $2.6 billion in Bitcoin ETFs and $182.1 million in Ethereum ETFs. Its largest stake is in BlackRock’s IBIT, valued at over $844 million, followed by Fidelity’s Bitcoin fund at just over $806 million. Additional holdings include the ARK 21Shares Bitcoin ETF, the Bitwise Bitcoin ETF, and the Grayscale Bitcoin Trust. 

Tudor Investment Corp, a hedge fund manager, increased its holdings in the iShares Bitcoin ETF. This ETF is the largest, with over $55 billion in assets. The fund’s stake grew from 4.4 million to 8 million shares, doubling its position. The value of these holdings rose with Bitcoin’s price, reaching $426.9 million. This was a sharp increase from $159.9 million at the end of September.

Moreover, Investment bank Goldman Sachs recently revealed holdings exceeding $1.5 billion in U.S. spot Bitcoin ETFs. This includes approximately $1.2 billion in IBIT and $288 million in Fidelity’s Bitcoin fund (FBTC).

States and Political Developments Shape Bitcoin ETF Trends

The increasing interest from institutions in BlackRock’s Bitcoin ETF coincides with a shift in political attitudes toward Bitcoin. Trump’s proposed crypto reserve could significantly impact Bitcoin’s mainstream adoption in the U.S., although some states are already exploring their own investment plans. Two states have rejected Bitcoin reserve bills. Meanwhile, 22 states are either reviewing or actively considering similar legislation, according to Bitcoin Reserve Monitor.
