The biggest US VC-funded companies of 2025: titans of innovation

The venture capital (VC) industry has started the year well, with OpenAI breaking a record this week when it raised $40 billion on Monday. Other companies like Elon Musk’s xAI and Anthropic have continued to do well. This article ranks the biggest VC-funded companies in 2025.

Biggest US VC-funded companies in 2025

SpaceX 

Elon Musk’s SpaceX is the biggest VC-funded company in the world with an estimated valuation of over $423 billion after raising over $11.2 billion in funding. Some of iits investors are Fidelity Investments, Founders Fund, Google, and Andreessen Horowitz.

SpaceX has become the biggest provider of satellite internet in the globally. It has also become a giant government contractor that has secured goods worth billions of dollars in the past few years. 

Its main advantage is its first-mover advantage, especially in the satellite internet industry. While other companies like Eutelsat are aiming to gain market share in this industry, the reality is that SpaceX is much further ahead. The same is true in its launch business, where it is a respected company in terms of costs.

OpenAI 

OpenAI, the parent company of ChatGPT, is the second-biggest VC-funded company in the in United States. It broke a record on Monday when it raised $40 billion from investors like Softbank. The new fundraising brought its valuation over $300 million, in line with ByteDance, the parent company of TikTok. 

OpenAI will receive $10 billion of this funding instantly, and the rest in the 12 months. The remainder is contingent on the company changing its business model from a non-profit to a profit-based firm.

Stripe 

Stripe is another top VC-funded company in the USA. It has raised over $8.4 billion, and its estimated valuation is about $91 billion. 

Stripe is a major player in the payment service, where it offers solutions to companies like OpenAI, Amazon, Anthropic, and Airbnb. It is a major competitor to other companies like PayPal, Adyen, GoCardless, and Square. 

Stripe’s real valuation will become known when it files for an initial public offering, a move that is expected to happen in the next few years. 

Databricks

Databricks is a top VC-funded company that has been in the business since 2013. The company offers a data warehousing solution used by companies like Santander, Siemens, Shell, Toyota, JetBlue, and Warner. Bros. Discovery.

Databricks has raised over $14.4 billion and is now valued at over $72 billion. Its top investors are VC firms like Thrive Capital, a16z, T. Rowe Price, Morgan Stanley, and Franklin Templeton. 

Anthropic

Anthropic is a top AI company valued at over $65 billion after raising over $11.5 billion. It has received most of these funds from Amazon, which provides it with its data center infrastructure. 

Anthropic has also raised funds from Google, Lightspeed Venture Partners, and Menlo Ventures. The company has built Claude, a ChatGPT rival it hopes will be a better competitor to ChatGPT and other models. 

xAI

Elon Musk’s xAI has become one of the fastest-growing companies globally. Established in 2023, it has raised over $12 billion, giving it a valuation of over $50 billion. xAI has even used its financial might to acquire X, formerly known as Twitter, a deal that has created a company valued at $133 billion. As I wrote last week, I believe that xAI’s Grok, is the biggest threat to Google because of its better answers.
