Jane Street appears to hold a bitcoin position worth about $990 million through spot bitcoin exchange-traded funds (ETFs).

Bitcoin Magazine reported on Aug. 17 that the position is equivalent to 15,394 BTC at current prices, but the holding is in ETF shares rather than spot bitcoin.

A disclosure filed with the U.S. Securities and Exchange Commission (SEC) showed Jane Street allocated a total of $990 million across major spot bitcoin ETFs, including BlackRock's IBIT (iShares Bitcoin Trust), Fidelity's WBTC (Wise Origin Bitcoin Fund) and Grayscale's GBTC (Bitcoin Trust). Of that, $828 million was concentrated in BlackRock's product.

BlackRock's product remains the largest among spot bitcoin ETFs approved and launched in early 2024. The fund has attracted more money than other cryptocurrency ETFs, and its assets under management are tallied at $47.3 billion. Jane Street's position can be seen as forming on top of that flow of funds.

The disclosure again confirmed a trend of large financial firms increasing bitcoin exposure through regulated securities products. Major institutions are taking part in bitcoin price moves by buying ETF shares listed on exchanges. Pension funds and U.S. state governments have also added spot bitcoin ETFs alongside technology stocks and other U.S. equities.

Jane Street's disclosure is also drawing attention alongside swings in the company's performance. Jane Street revealed its first monthly loss in about 10 years, with losses in July of about $15 billion. Weak investment performance in the AI-focused hedge fund Situational Awareness and failed bets on Asian stock markets were cited as major factors. Losses from AI investments and margin calls overlapped, sharply shaking the fund's performance.

On an annual basis, the profit trend remains strong. Bloomberg tabulations showed Jane Street's year-to-date net trading revenue topped $40 billion. That exceeds its full-year 2025 record of $39.6 billion, when Jane Street set a Wall Street record by beating Goldman Sachs and JPMorgan.

Other large Wall Street investment firms are also disclosing bitcoin positions. U.S. investment firm Edelman Financial and Tudor Investment Corporation also disclosed sizable bitcoin holdings last week, and Abu Dhabi's sovereign wealth fund is also cited as having increased exposure through spot bitcoin ETFs.

Amid that trend, spot bitcoin ETFs are becoming a main entry route for institutional money. Jane Street's case shows that large trading firms can build sizable positions through ETFs without directly holding bitcoin. The fact that most of its holdings are concentrated in BlackRock's product also highlights a skewed flow of funds within the spot bitcoin ETF market.
