Largest US Venture Funding Deals Of 2025

Venture capital is a type of private equity typically invested into emerging startup companies that investors believe have high growth potential and will deliver outsized returns.

In exchange for equity stakes in the companies, venture capital firms and other investors provide capital to private companies that they believe have the potential for successful exits when they eventually go public or are acquired at a premium.

A VC funding deal typically has one or two lead investors, with other investment firms participating in the round by providing smaller stakes.

Crunchbase VC funding data comes from a variety of sources, including ​​an active community of contributors, more than 4,000 global investment firms that submit deal data to Crunchbase, startup and venture capital news sources, and an in-house data team.

Venture-funded startups are private companies that have received funding from venture capitalists.

These companies can range from very small, early-stage startups looking for seed-round funding, to large unicorn companies (private companies with a valuation of $1 billion-plus) that are on the verge of going public or being acquired.

Most venture-funded startups are in the technology industry, due to the sector’s potential for fast growth and outsized returns for investors. But companies in other industries such as retail and consumer goods also receive VC funding.

There are several stages of venture funding, starting with angel or pre-seed funding to the very youngest startups and ending with later-stage funding to established, pre-IPO startups.

• Angel: An angel round is typically a small round designed to get a new company off the ground. Investors in an angel round include individual angel investors, angel investor groups, friends and family.
• Pre-seed: A pre-seed round is a pre-institutional seed round that either has no institutional investors or is a very low amount, often below $1 million.
• Seed: Seed rounds are among the first rounds of funding a company will receive, generally while it is young and working to gain traction. Round sizes typically range between $1 million and $3 million, though larger seed rounds have become more common in recent years. A seed round typically comes after an angel round (if applicable) and before a company’s Series A round.
• Series A and Series B: These are funding rounds for earlier-stage companies and range on average between $5 million and $30 million.
• Series C and onward: For later-stage and more-established companies, these rounds are usually at least $20 million, but are often much larger.

Other sources of private-company funding include private equity or growth funding, debt financing and crowdfunding.

The largest venture funding deal to a U.S.-based startup in 2024 was also one of the largest startup funding deals ever. That was Databricks‘ $10 billion raise led by Thrive Capital at a $62 billion valuation. 

The other largest U.S. startup funding deals of 2024 were also to AI-related companies:

OpenAI raised the second-biggest round of the year — a $6.6 billion deal at a post-money valuation of $157 billion, also led by Thrive Capital. The round made the ChatGPT creator one of the most valuable private companies in the world and also included investment from the likes of Altimeter Capital, Fidelity, Khosla Ventures, Microsoft, Nvidia, SoftBank and Abu Dhabi-based MGX.

xAI raised a $6 billion round in May that included investment from the likes of Valor Equity Partners, Andreessen Horowitz, Sequoia Capital and Fidelity Management & Research Co., among others. The funding valued the company at $24 billion post money. In November, the Elon Musk-founded rival to OpenAI raised another $6 billion in a funding round valuing it at $50 billion. The newer round included investment from the Qatar Investment Authority, Valor Equity Partners, Andreessen Horowitz and Sequoia Capital.

Autonomous vehicle company Waymo, which was spun out of Google’s labs, took in a big round from its former parent, as Alphabet invested $5.6 billion into the firm in a deal announced in October 2024. The new round valued the company at more than $45 billion and was the startup’s first raise since a $2.5 billion round in 2021.

Also in November, Amazon agreed to invest another $4 billion in AI startup Anthropic, yet another ChatGPT rival with an AI assistant called Claude. The latest investment meant Amazon had invested $8 billion into Antropic, retaining its minority stake in the startup.

Artificial intelligence dominated venture capital investment in 2024. But we’ve already run a list of the biggest rounds raised by AI-related startups, so what about some of the other industries that got big deals in 2024?

The biggest rounds raised by U.S.-based startups not necessarily focused on AI in 2024 were:

North Carolina-based Epic Games raised $1.5 billion in February 2024 through a new partnership with Disney to help give more exposure to the company’s characters and properties — including Marvel Comics characters. However, the round was a drastic drop in valuation, as it was reported Disney invested at a $22.5 billion valuation. Founded in 1991, the Fortnite creator has raised nearly $8 billion to date, according to Crunchbase data.

San Francisco-based green infrastructure investor and operator Generate Capital raised a $1.5 billion round from a variety of investors, including the California State Teachers’ Retirement System. Generate invests in an array of infrastructure projects, from community solar systems to municipal wastewater treatment to electrifying fleets.

Tricentis got a $1.3 billion investment from private equity firm GTCR valuing the software testing startup at $4.5 billion. The Austin, Texas-based startup was founded in 2007 in Austria. Insight Partners took majority ownership in 2017.

Cloud security startup Wiz locked up the biggest cybersecurity round of the year as it raised $1 billion at a $12 billion valuation. The round was co-led by Andreessen Horowitz, Lightspeed Venture Partners and Thrive Capital. Originally founded in Israel in 2020, Wiz acquired New York-based cloud detection and response startup Gem Security earlier in the year. Wiz has talked openly about hitting $1 billion in ARR as it heads to an IPO.

Venture capital has not dried up. While venture capitalists aren’t investing as much of their capital as they were during the investment boom of 2021, investors still have plenty of capital available to deploy.

With nearly $314 billion in global venture capital startup funding in 2024 — according to Crunchbase data — investors are still putting big money into the market at a rate that seems like a return to the pre-2021 boom days.

Such a pace could prove healthier and more sustainable for the market, as the market became very frothy during its height.
