According to the latest 13F filings, Wall Street quant giant Jane Street significantly reduced its exposure to Bitcoin ETFs and related assets in the first quarter of 2026. Driven by Bitcoin's quarterly price drop of over 20%, this tactical rebalancing appears more like an optimization of the crypto asset structure rather than a full retreat.

Specifically, its BlackRock IBIT holdings plummeted 71% quarter-over-quarter to approximately $225 million, Fidelity FBTC holdings were cut by about 60% to $115 million, and its previously increased MicroStrategy position also decreased by 78%. Concurrent with the reductions, Jane Street heavily tilted toward the Ethereum ecosystem, increasing its Ethereum ETF holdings by about $82 million and significantly adding to crypto stocks like Galaxy Digital.

This is clearly an internal "style rotation." As a core market maker for crypto ETFs, Jane Street's move aims to adjust strategic priorities but does not indicate a bearish outlook on the entire crypto market. Funds are still circulating within the crypto ecosystem, and the shift into Ethereum could even expand the overall digital asset footprint further. #JaneStreet减持比特币ETF
