Jane Street is reported to be in talks with a small group of investors, including Pimco, to move its $11bn debt load from public markets into a private credit vehicle, a step that would support further investment in artificial intelligence infrastructure. The financing could be upsized and, according to one person involved, may be finalised as soon as next week.
The proprietary trading firm currently reports its financials quarterly to a broad base of public debt holders. A shift to a private structure would allow Jane Street to limit the disclosures it makes on its financial position, even as its borrowing costs could rise. Private-market borrowing typically costs at least 0.25 percentage points more than public-market financing for an investment-grade company, according to US-based capital market bankers, meaning any refinancing on these terms would carry a materially different cost profile than Jane Street's existing public debt.
Pimco, the bond investor owned by Allianz, has increasingly moved beyond its historic focus on publicly traded fixed income to lead a series of high-profile private transactions aimed at boosting investment returns. The firm has used its scale in credit markets, together with its ties to Allianz, to secure large financing mandates. Alongside firms such as Apollo Global and Blackstone, Pimco has taken a growing role in underwriting corporate loans directly or with a limited number of partners, a pattern consistent with the structure now reportedly under discussion with Jane Street.
Jane Street does not manage outside investor capital but, like rival firm Citadel Securities, borrows from debt capital markets to fund its operations. The firm has expanded in recent years from high-frequency trading into longer-term positions, including investments in AI businesses Thinking Machines Lab and Anthropic. It generated $16.1bn in trading revenues and net income of $10.3bn in the first quarter, and reported revenues of roughly $40bn in 2025, as it has expanded market share against established banks including JPMorgan Chase and Goldman Sachs. Its Q2 results were expected to be reported to lenders within a few weeks, though a private financing deal completed as soon as next week would pre-empt that public disclosure.
Jane Street's recent activity extends beyond its own balance sheet. It contributed to a $2.6bn loan package that helped CoreWeave secure financing partly guaranteed by AI compute contracts, and it holds an investment in Situational Awareness, the hedge fund run by 24-year-old Leopold Aschenbrenner. Situational Awareness was required to sell a large equity portfolio to Citadel, an outcome tied to losses on the fund's leveraged position during the recent sell-off.
A completed shift of Jane Street's debt into private hands would reduce the volume of financial information available to the wider market on one of Wall Street's most active proprietary trading firms, while tying its future borrowing costs more closely to terms set by a concentrated group of private lenders rather than public bond markets.
