Jane Street holds nearly $1 billion in spot Bitcoin ETFs, according to a fresh SEC filing, putting the trading firm among the biggest institutional holders of the products. The stake — about $990 million — is spread across three funds, with the bulk sitting in BlackRock's iShares Bitcoin Trust.
Inside the stack
The filing shows Jane Street owns roughly 15,394 BTC worth of exchange-traded funds. BlackRock's fund accounts for $828 million of that total, with the rest split between Fidelity's Wise Origin Bitcoin Fund and Grayscale's Bitcoin Trust. BlackRock's iShares Bitcoin Trust is the largest spot Bitcoin ETF on the market, managing $47.3 billion in assets.
That's a big number for a firm that has historically been cautious about crypto. Jane Street has traded Bitcoin futures and options for years, but this is the first time its spot ETF holdings have been laid out this clearly.
A rough July, a record year
The disclosure lands right after Jane Street posted its first losing month in about a decade. July losses hit roughly $15 billion, driven by a stake in AI-focused hedge fund Situational Awareness and bad bets in Asian equity markets.
Even so, the firm has made over $40 billion in net trading revenue year-to-date — already exceeding its 2025 record of $39.6 billion. The Bitcoin ETF position, while notable, is small next to that number. But it signals that the firm sees these funds as a core holding, not a side bet.
Other Wall Street names are in
Jane Street isn't alone. Edelman Financial and Tudor Investment Corporation have also revealed significant Bitcoin positions, as have Abu Dhabi's sovereign wealth funds. The filings don't say whether any of them plan to add or trim, but the trend is clear: the biggest traditional money managers are treating spot Bitcoin ETFs as a standard allocation.
The next round of quarterly filings will show whether Jane Street's stake grew or stayed flat. Given the July losses, it wouldn't be surprising if the firm trimmed some positions to raise cash. But the fact that it held through a brutal month says something.
