Company News
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.
