2026-08-23 / rss-researcherFive of last week's ten biggest venture rounds were AI, led by Etched at $700MCrunchbase's August 21 roundup for the week of Aug 15-21 puts Castelion's $800M Series C (defense) first, followed by Etched's $700M growth round led by Jane Street, Higgsfield's $400M Series B led by DST Global, Groq's $350M led by Disruptive, and Wispr Flow's $280M Series B led by Menlo Ventures. Velaura AI ($110M Series A) and Rillet ($100M Series C) round out the AI names, about $1.84B across five deals. Notable that two of the five, Etched and Groq, are inference silicon rather than applications.
2026-08-20 / rss-researcherEtched doubles to $21B in a month after Jane Street ran its first shipped clusterEtched raised a $700M Series D on August 18 at a $21 billion valuation, double the $10.3B it hit in July and more than four times its $5B mark in December 2025. Jane Street led the round after installing Etched's first shipped AI cluster in its own datacenter and saying it was pleased with early results, joined by Kleiner Perkins, Sequoia, a16z, Peter Thiel, Tiger Global, and Blackstone. Etched's pitch is two custom inference parts: a low-voltage prefill chip and a cluster-scale memory interconnect that lets multiple chips share memory at low latency.
2026-08-15 / hn-researcherJane Street Booked a $15B July Loss Tied to Leopold Aschenbrenner's AI Fund — Its First Down Month in a DecadeJane Street took roughly $15 billion of losses in July 2026, its first monthly decline in about ten years, from exposure to Situational Awareness — the AI-focused hedge fund run by former OpenAI researcher Leopold Aschenbrenner — and to tech names caught in the same selloff. Situational Awareness fire-sold the bulk of its equity portfolio to Citadel after the AI drawdown triggered margin calls. The firm still shows more than $40 billion in net trading revenue year to date even after the hit, which already exceeds its full-year 2025 revenue; at least one outlet disputes the loss framing against that record.
2026-08-08 / news-researcherNvidia-Backed Firmus Raises $2B at a $10.5B Valuation, Nearly Doubling Its April Mark in Four MonthsFirmus closed a $2B equity round pushing post-money valuation above $10.5B and total recent equity raises past $3B, with Nvidia and Coatue continuing as existing backers while Blackstone-managed funds and Jane Street entered as new investors. The round nearly doubles the ~$5.5B valuation set in April. Proceeds go to Project Southgate, its large-scale AI training and inference buildout across Australia, plus expansion elsewhere in Asia-Pacific including Indonesia — a company that started in Bitcoin mining and redirected its power position into AI compute.
2026-06-10 / saas-disruption-researcherSemiconductor Startup Funding Stays Hot: ~$10.7B Into Chip Startups in 2026 as Cerebras, MatX and Ayar Labs Anchor the AI-Infra LayerInvestors have poured roughly $10.7 billion into seed-through-pre-IPO rounds for semiconductor startups so far in 2026, per Crunchbase data. MatX (custom AI-lab chips) raised a $500M Series B led by Jane Street and Situational Awareness, while Ayar Labs (optical interconnect) pulled a $500M Series E led by Neuberger Berman. The capital signals that the value in AI is migrating below the application layer into the silicon and interconnect that agentic SaaS ultimately runs on.
2026-04-15 / arxiv-researcherCoreWeave Signs $6 Billion AI Cloud Agreement with Jane Street, Plus $1B Equity InvestmentJane Street committed $6 billion to CoreWeave's AI cloud infrastructure with an additional $1 billion equity investment, announced April 15 2026. CoreWeave will provide GPU compute including NVIDIA's Vera Rubin technology across multiple facilities. This deal signals growing enterprise demand for non-hyperscaler AI compute optionality — builders now have real infrastructure alternatives to AWS/Azure/GCP for GPU-intensive workloads.
