Jane Street acts as a liquidity provider and market maker, trading on over 200 venues across 45 countries to help keep global markets flowing. Its product is not a single app but a set of trading strategies and technologies that automatically buy and sell securities to provide liquidity, driven by quantitative analysis and sophisticated systems. The company differentiates itself through its people and culture: humble, collaborative teams spread across major offices, a strong emphasis on hands-on training, and cross-office idea sharing. This focus on growth through people, teaching, and continuously improving trading technology sets Jane Street apart from competitors who may rely more on hardware or brand alone. The company’s goal is to stay competitive by inventing new trading strategies, technologies, and processes, solving new problems, and building a long-running, dynamic market-making platform.

Jane Street suffered a $15 billion loss in July linked to its investment in Situational Awareness, an AI-focused hedge fund, and the broader AI stock selloff, according to Reuters sources. The trading firm took hits from both Situational's drawdown and its own long positions in Asian non-AI stocks. Despite July's losses, Jane Street has generated over $40 billion in trading revenue year to date, surpassing major banks and rivals. Situational, run by former OpenAI researcher Leopold Aschenbrenner, conducted a fire sale of its stock portfolio to Ken Griffin's Citadel after margin calls triggered by the AI selloff. In an internal note, Jane Street executives said AI-exposed stocks dropped significantly in July, with major memory and semiconductor stocks falling around 50%. The firm plans to be "more selective" about risk and has reduced positions in affected areas.
Jane Street is negotiating a private credit deal to refinance its $11 billion debt load, which could total as much as $15 billion, according to people familiar with the matter. The market-making giant is in talks with firms including Pacific Investment Management Co. about converting its public debt into a private vehicle. The deal would limit Jane Street's financial disclosures to a smaller group of investors rather than quarterly public updates. Terms are expected to be finalised in coming days, with the firm potentially tendering existing bonds as soon as Monday. The move would provide financial flexibility to invest in private companies and artificial intelligence infrastructure. Jane Street pulled in $39.6 billion of trading revenue last year and notched a record first quarter with $16.1 billion in trading revenue.
Etched, an AI chip startup founded by three Harvard dropouts in 2022, has raised $300 million in Series C funding at a $10.3 billion valuation. The round was led by Sequoia, with participation from Andreessen Horowitz, SK Hynix, Jane Street, and Diffusion Capital. The company has doubled its valuation from $5 billion in December. Last month, Etched announced it had successfully manufactured its chips and booked $1 billion in orders. Etched designs systems specifically for AI inference, creating two new components: a prefill chip using low-voltage technology and a cluster scale memory system. The company aims to deliver faster speeds at lower costs. Despite initial skepticism, Etched has attracted prominent investors including Peter Thiel, Andrej Karpathy, and Geoffrey Hinton through private demos. The startup now employs 400 people and operates a 2 megawatt data centre.
Fluidstack has raised $830 million in a Series A funding round at a $7.5 billion valuation. The round, which closed in January, was led by Situational Awareness, the AI-focused investment firm founded by former OpenAI researcher Leopold Aschenbrenner. The AI infrastructure startup will use the capital to expand its global data centre operations. Fluidstack acquires power, designs and constructs data centres, and operates computing infrastructure for AI labs. The company claims it can deliver gigawatts of capacity within six months, compared with the industry standard of 18 to 24 months. Fluidstack's largest project is a partnership with Anthropic to build $50 billion of computing infrastructure across the United States. Initial facilities are being developed in Texas and New York, with sites expected to come online throughout 2026.
Nvidia has agreed to invest approximately A$720 million (US$500 million) in Australian cloud infrastructure startup Firmus Technologies, according to the Australian Financial Review. The investment is part of a planned A$2 billion equity raising ahead of Firmus's Australian Securities Exchange IPO, targeted within 12 months. The funding nearly doubles Firmus's valuation to around US$15.5 billion post-money. Nvidia will invest through preference shares that convert to ordinary shares upon IPO completion. Firmus plans to use the capital to purchase Nvidia AI chips for a data centre in Launceston, Tasmania, and expand its Australian infrastructure pipeline. Shareholders will vote on the capital raising at an extraordinary general meeting on 31 July, alongside a proposed 50-for-1 share split.
