Susquehanna International Group revealed investments totaling $1.3 billion in spot Bitcoin ETFs in its May 7 13F filing. The company disclosed holdings of 17.3 million shares of Grayscale's GBTC across three separate investments, amounting to $1.1 billion.

Additionally, Susquehanna purchased shares in several other spot Bitcoin ETFs, including Fidelity's FBTC, BlackRock's IBIT, Bitwise's BITB, Ark 21Shares's ARKB, VanEck's HODL, WisdomTree's BTCW, Invesco's BTCO, and Valkyrie's BRRR, totaling $200 million.

These investments represent a fraction of the company's total reported investments of $575.9 billion in its latest 13F. Susquehanna's acquisitions encompass investments in nine out of the ten existing spot Bitcoin ETFs, with Franklin Templeton's EZBC being the exception.

The company's move reflects the growing institutional interest in spot Bitcoin ETFs, with other firms such as Hightower Advisors, SouthState Bank, BNP Paribas, and Burkett Financial Services also reporting similar investments. This institutional interest aligns with predictions from members of BlackRock and Bitwise regarding continued investment in spot Bitcoin ETFs.

The disclosed 13F filings cover purchases made before March 31, suggesting that more recent investments may not yet be revealed. As of May 7, spot Bitcoin ETFs held a combined $52 billion in assets under management, with inflows totaling $11.7 billion as of May 6.
