Jane Street's Big Moves in 2025: From Record Revenue to New Investments

As 2025 comes to a close, one name that has been appearing increasingly in financial headlines is Jane Street. The Chicago-based trading and asset management firm has been making waves with its Q3 performance, a new ETF partnership, and recent equity investments. For investors and market observers, these moves offer a glimpse into Jane Street's broader strategy and how it's navigating a rapidly evolving market landscape.

Jane Street Group, LLC is a well-known name in the world of electronic trading and capital markets. Founded in 1999, it has built a reputation for its algorithmic trading expertise and market-making services. In recent years, the firm has expanded its reach into more traditional investment vehicles like ETFs and has been growing its stake in some high-profile companies. Its role as a market maker means Jane Street helps ensure liquidity in various securities, especially in options and ETFs. This makes it a key player in market function and an interesting entity for investors to watch according to market analysis.

The past few months have seen some remarkable moves from Jane Street. For example, in Q3 2025, the firm reported a staggering $6.83 billion in net trading revenue—an 18% increase compared to the same period in 2024. This brings the year-to-date total to $24 billion, already surpassing the full-year 2024 total of $20.5 billion. Much of this growth was driven by a $830 million gain from its investment in Anthropic, a major player in artificial intelligence. This gain accounted for about 12% of its Q3 revenue, highlighting the firm's growing exposure to the AI sector.

Jane Street’s increasing focus on AI-related investments, particularly in firms like Anthropic, has drawn attention from both the financial and tech communities.

. The AI sector has been one of the most volatile in recent years, and Jane Street’s success in navigating this space may serve as a bellwether for future trends in high-tech financial investments.

Beyond trading, Jane Street has also been involved in some high-profile equity moves. For instance, the firm recently increased its stake in Hinge Health Inc. by acquiring 2,085,039 shares, increasing its ownership to 5.6%. Notably, Jane Street has filed with the SEC that it is not seeking to exert control over the company and that its ownership is not intended to influence corporate decisions. Still, the size of the stake makes it a significant player in the firm's shareholder base.

Another recent development worth noting is Jane Street's role as the lead market maker for AllianceBernstein's new ETF, the AB US Equity ETF (XCHG), which launched on the NYSE on December 15, 2025. XCHG is an actively managed fund that aims for long-term capital growth by investing at least 80% of its assets in U.S. equities. This partnership with AB aligns with Jane Street's broader push into ETF-related activities and signals the firm's growing presence in the ETF market according to market analysis.

For investors, these developments are more than just company news—they reflect broader market dynamics. Jane Street's success in Q3, especially in AI-related gains, suggests that the firm is adapting well to the evolving financial and technological landscape. Meanwhile, its role in ETFs and ownership stakes shows it is not just a trading shop but increasingly a strategic player in the capital markets. For individual investors, this means Jane Street's actions could impact the liquidity and volatility of certain securities, especially those it trades or owns.

Looking ahead, the coming months will be crucial for Jane Street. The firm is already facing regulatory challenges, notably in India, where the SEBI has ordered it to disgorge ₹4,844 crore for alleged market manipulation. While Jane Street has paid the amount, it is contesting the order, which could have wider implications for how global trading firms operate in emerging markets. In the U.S., the firm's continued growth in the ETF space could mean more opportunities for investors looking to access actively managed products with strong liquidity support according to industry reports.

At the end of the day, Jane Street's 2025 has been defined by bold moves—whether in the form of record trading revenue, strategic investments, or new product offerings. These moves position the firm not just as a trading powerhouse but as a more diversified financial services player. For investors, this means Jane Street is likely to remain a key player to watch, especially as the markets continue to evolve in 2026.
