Jane Street Slashes Spot Bitcoin ETF and Strategy Holdings

Jane Street is a major Wall Street quantitative trading firm and ETF market maker, and shifts in its holdings are often viewed as a gauge of institutional capital flows. Since U.S. spot Bitcoin ETFs began trading on Jan. 11, 2024, they have become an important channel for traditional investors seeking crypto exposure. However, 13F filings show only quarter-end long positions in U.S.-listed equities and exclude short positions, swaps and complete hedging activity, so reductions do not necessarily indicate a bearish view.

In a May 12, 2026, filing with the U.S. Securities and Exchange Commission covering holdings as of March 31, Jane Street reported that its IBIT position fell 71% from the previous quarter to $225.6 million, while its FBTC position declined 60% to $115 million. Its stake in Strategy, formerly MicroStrategy, fell 78% to $26.18 million. Over the same period, the firm added about $82 million in Ether ETF holdings.
