Crunchbase News reports that U.S.-based AI infrastructure companies raised $4.8 billion across three of the week’s largest announced venture rounds. Crusoe raised $3 billion in a Series F co-led by Atreides Management and Valor Equity Partners, with Mubadala Capital participating. The financing values Crusoe at $30 billion, according to Crunchbase, and brings its reported total funding to nearly $7.2 billion. Fluidstack raised $1.5 billion in a private-equity round led by Jane Street Capital, valuing the company at $18 billion and bringing its total reported funding above $2.6 billion. Gimlet Labs raised $300 million in a Series B led by Andreessen Horowitz. Crunchbase News says Gimlet is developing an cloud that distributes AI workloads across different chip types, and that the round values the company at $3 billion. The article also lists major financings for AI-related companies including Lyte AI, which raised $165 million for robotics sensing, perception and AI software, and HiddenLayer, which raised $100 million for security tools aimed at AI models, agents and workflows. The figures are based on Crunchbase’s database of announced rounds involving U.S.-based companies from Aug. 29 through Sept. 4, 2026. Crunchbase notes that its database may include reporting delays. The source does not independently verify the companies’ valuations, uses of funds or commercial performance. It reports no consumer access terms or product pricing because these are financing announcements, not product launches.
Crusoe’s announcement is described as a Series F, while Fluidstack’s transaction is described as a private-equity round rather than a venture series. Crunchbase attributes the reported valuations and funding totals to its coverage and identifies the investors named for each transaction.
Gimlet Labs’ Series B is tied in the article to an cloud that distributes workloads across chip types. The same article separately identifies Lyte AI’s financing as supporting robotics sensing, perception and AI software, and HiddenLayer’s as supporting security tools for AI models, agents and workflows.
These entries are announcements recorded in Crunchbase’s database, not independently verified operating results. Crunchbase notes reporting delays, and the source does not provide consumer access terms or product pricing.

The financings show that capital is concentrating around the infrastructure needed to train and run AI systems, including data centers, cloud capacity, optimization, robotics hardware and AI-specific security. That matters because infrastructure investment can influence which companies can offer large-scale AI services and how quickly enterprises can deploy them.
Crusoe and Fluidstack are raising capital at valuations of $30 billion and $18 billion respectively, according to Crunchbase News. Those figures indicate that investors are assigning substantial value to companies supplying capacity as demand for AI workloads grows. The source does not establish whether either company is profitable, whether the valuations will hold, or how much of the announced capital has been received.
Gimlet Labs’ focus on distributing workloads across different chip types addresses a practical constraint in AI deployment: running models efficiently can require more than simply acquiring additional GPUs. If the company’s approach works at production scale, it could give cloud operators more flexibility in matching workloads to available hardware. The source provides no independent performance results or customer metrics.
The list also places physical AI and AI security within the same funding pattern. Lyte AI is developing sensing and perception systems for robots, while HiddenLayer is building protection for AI models, agents and workflows. These are commercially significant areas, but the article does not document general availability, customer outcomes, technical benchmarks or pricing for either company.

Watch whether the announced financings translate into operational capacity, disclosed contracts and measurable improvements in AI infrastructure efficiency. Further reporting should also clarify the terms and closing status of the rounds, the companies’ revenue and deployment figures, and whether their valuations are supported by independently reported results.
The source says Crusoe serves customers including OpenAI, Microsoft and Meta, but it does not provide contract values, capacity figures or delivery timelines. Those details would help distinguish signed demand from broader market positioning.
Fluidstack’s round was led by Jane Street Capital and is described as private equity financing. The article does not explain the ownership structure, use of proceeds, or whether the money will fund new data centers, hardware purchases or other expansion.
Crunchbase’s methodology covers announced rounds in a defined period and warns of possible database lag. Later disclosures may revise the amounts, dates, investor lists or valuations reported here.
There is no reported end-user access, availability or pricing associated with the companies’ infrastructure and security products in this source.
