Last year was a remarkable year for the AI industry in the US and beyond, with 49 startups raising funding rounds worth $100 million or more. However, 2025 is already showing signs of surpassing that mark, with nearly a dozen US AI companies having raised more than $100 million in funding rounds, and one round exceeding $1 billion.

According to our count at TechCrunch, three companies raised more than one "mega-round" last year, and seven companies raised rounds at $1 billion or larger. While it's still early in the year, the pace of large funding rounds for AI startups shows no signs of slowing down.

One of the most notable funding rounds of the year so far is Anthropic's $3.5 billion Series E round, which valued the AI research and large language model company at $61.5 billion. The round was led by Lightspeed and included participation from Salesforce Ventures, Menlo Ventures, and General Catalyst, among others.

Other notable funding rounds include Together AI's $305 million Series B round, which valued the open source generative AI and AI model development infrastructure company at $3.3 billion. Lambda, an AI infrastructure company, raised a $480 million Series D round that valued the startup at nearly $2.5 billion. Pittsburgh-based Abridge, an AI platform that transcribes patient-clinician conversations, was valued at $2.75 billion in a Series D round.

Eudia, an AI legal tech company, raised $105 million in a Series A round led by General Catalyst, while AI hardware startup EnCharge AI raised a $100 million Series B round led by Tiger Global. AI legal tech company Harvey raised a $300 million Series D round that valued the 3-year-old company at $3 billion.

In January, synthetic voice startup ElevenLabs raised a $180 million Series C round that valued the company at more than $3 billion, while Hippocratic AI, which develops large language models for the healthcare industry, announced a $141 million Series B round that valued the company at more than $1.6 billion.

The pace and size of these funding rounds suggest that investors are increasingly bullish on the potential of AI startups to drive innovation and growth in various industries. As the year unfolds, it will be interesting to see how these companies deploy their funding to drive further advancements in AI research and applications.

With nearly a dozen US AI companies having already raised $100 million or more in funding rounds, 2025 is shaping up to be a monumental year for the AI industry. As the industry continues to evolve and mature, it will be important to track the progress of these companies and the impact they have on their respective industries.
