BlackRock IncJane Street's $828M stake in IBIT highlights strong institutional demand for BlackRock's Bitcoin ETF.

Quant trading giant Jane Street disclosed more than $1 billion in U.S. spot Bitcoin ETF holdings as of June 30, with the largest position in BlackRock's IBIT at $828 million. The firm also held stakes in Fidelity's FBTC and Grayscale's GBTC, though the filing reflects ETF shares rather than direct Bitcoin ownership. The disclosure comes after Jane Street took a $15 billion hit in July from exposure to AI-focused hedge fund Situational Awareness and other tech stocks, its first monthly downturn in a decade, according to a Bloomberg report.
