The influx of institutional capital is expected to support Bitcoin prices while making it more sensitive than ever to macroeconomic forces. So who are the largest BTC ETF holders among institutions? Let’s find out.

Key Takeaways

  • The US state of Wisconsin became one of the first state pension funds to invest in cryptocurrencies.

  • Susquehanna International Group invested in 10 different spot BTC ETFs.
  • Bitwise CIO Matt Hougan said professional investors will increase allocation to spot BTC ETF in the months to come.

How Do We Know Which Institutions Invested in Spot BTC ETFs?

The U.S. Securities and Exchange Commission (SEC) requires investors with over $100 million in assets under management to file a quarterly report called Form 13F. In the report, investors have to disclose their holdings of publicly traded securities.

Form 13F is required to be filed within 45 days after the end of the quarter.


By studying Form 13F filings, market participants use 13F filings to study where institutions and professional investors are investing their capital.

The Bottom Line

The reception that spot crypto ETFs received from institutional investors in the U.S. has been surprisingly positive. According to Bitwise CIO Matt Hougan there is more to come as most investment houses have invested less than 1% of their portfolio into Bitcoin in the first quarter of 2024.

Hougan suggested that six months after initial allocation, firms will begin allocating across their entire books of clients.

Either way, extra markets have been unlocked for Bitcoin, and the demand is there.
