Kiplinger reports that younger AI companies are still attracting large investments at higher private valuations, even as questions grow about spending and whether the sector can meet investor expectations. The money is helping fund computing capacity, while the companies range from established revenue generators to early-stage ventures with little or no product or revenue.
AI start-ups are continuing to raise large sums at higher private valuations, according to a Kiplinger report, as investors bet that the industry can support multiple winners despite concerns about heavy spending and a possible AI bubble. The funding is also driving demand for computing capacity, including chips and memory used to train and run AI systems.
Kiplinger listed Anthropic at $1.2 trillion and OpenAI at $852 billion in its table of leading U.S. AI start-ups by valuation. The report also put Databricks at $190 billion, Cognition at $48 billion, Thinking Machines Lab at $45 billion, Project Prometheus at $41 billion, Safe Superintelligence at $32 billion, VAST Data at $30 billion, Perplexity at $20 billion and Sierra at $16 billion. The figures were attributed to CB Insights’ “State of AI: Q3 2025,” company press releases and news reports.
Those numbers describe private valuations, not public-market prices. Kiplinger cautioned that private valuations can change as companies raise new rounds of funding. It also reported that Anthropic and OpenAI expect to go public at higher valuations, but did not give a timetable or proposed offering values.
The report describes a broad range of businesses and financial positions. Databricks sells a cloud platform for data and analytics, while Project Prometheus, backed by Amazon founder Jeff Bezos, is focused on robotics and other physical hardware. Perplexity offers an AI-powered search engine. Kiplinger said some highly valued start-ups have small staffs and no product or revenue yet, while companies including Anthropic and OpenAI have substantial sales but are spending faster than revenue is growing.
Funding Is Expanding AI Compute Demand
The flow of capital matters beyond the start-ups receiving it. Kiplinger says much of the money is being directed toward computing power, either in companies’ own data centers or through outside cloud providers. That spending supports demand for Nvidia graphics processing units, as well as central processing units and memory.
The investment also indicates that backers are willing to finance a wide range of AI business models before all of them have demonstrated products, revenue or a path to profitability. That may give young companies resources to build and compete, but it leaves investors exposed to the possibility that expected demand or future earnings will not justify today’s valuations. The report raises those concerns but does not establish that the sector is in a bubble.
For readers tracking business and technology, the distinction between funding and commercial performance is central: a high private valuation signals what investors are willing to pay in a financing context, not proof that a company will become profitable or sustain its current growth.

A Range of Firms Beyond OpenAI
The report places the latest funding activity against the prominence of Anthropic and OpenAI, which dominate public attention but are not the only companies attracting capital. Its list includes firms focused on data infrastructure, search, robotics and other AI-related products, reflecting investors’ view that the market may accommodate different kinds of providers.
Kiplinger also included China-based ByteDance, TikTok’s owner, at a reported valuation of $480 billion and China’s DeepSeek at $59 billion. These figures were presented separately from its table of top U.S. start-ups. The article does not provide a common valuation date or a detailed methodology for comparing companies across countries, business models and funding rounds.
The report’s central point is that private funding rounds are moving valuations upward, while the companies’ maturity varies sharply. Some have operating products and sales; others are still bets on founders and plans. That difference limits what headline valuation figures alone can say about their current business strength.

Valuations Do Not Settle Returns
The report does not provide detailed, comparable financial statements for the companies, including current revenue, cash burn, debt or profitability. It also does not specify the exact dates of every valuation in its list. Because private valuations can reflect different funding terms and market conditions, the figures are not directly equivalent to public stock prices.
It remains unclear whether the companies with limited products or revenue can convert investor funding into durable businesses, and whether firms with significant sales can slow spending enough to become profitable. The report also does not confirm dates or terms for planned public offerings by Anthropic and OpenAI. Concerns about an AI bubble are presented as risks, not as a proven description of the market.

Funding Rounds and IPO Plans
The next developments to watch are new financing rounds, company disclosures about revenue and spending, and any concrete filings or schedules for the public offerings Anthropic and OpenAI expect to pursue. Those disclosures could clarify whether private valuations continue to rise and how closely investors’ expectations track operating results.
For now, Kiplinger’s report presents a fast-moving funding picture rather than a final verdict on which companies will succeed. Further valuation changes may follow as investors commit new capital, but the source does not identify a specific next funding event or IPO date.

Key Questions
Which AI start-ups had the highest valuations in Kiplinger’s list?
Kiplinger listed Anthropic at $1.2 trillion and OpenAI at $852 billion. The figures were drawn from sources including CB Insights’ Q3 2025 report, company announcements and news reports.
Are these valuations the same as public stock prices?
No. They are reported private-company valuations, generally associated with funding activity, and are not public-market prices. Kiplinger notes that private valuations can change as new rounds are completed.
Where is the investment money going?
Kiplinger says much of it is going toward computing capacity, including companies’ own data centers and cloud computing. That spending supports purchases of GPUs, CPUs and memory.
Does the report show that AI is in a bubble?
No. It cites concerns about overspending and bubble risk but does not establish that a bubble exists. It also describes companies with very different levels of revenue, products and spending.
