U.S. artificial intelligence (AI) startups have reportedly secured capital in 2025 at a pace consistent with the prior year's record, with 49 companies raising $100 million or more, according to a TechCrunch report. This matches the total number of such funding rounds recorded in 2024.
The report highlights an increasing trend in 2025 where more companies have completed multiple funding rounds exceeding $100 million within the year, surpassing the frequency observed in 2024. In the previous year, three companies secured more than one “mega-round,” and seven companies raised rounds of $1 billion or larger.
Notable investments in 2025 include Anysphere, developer of the Cursor coding platform, which raised $2.3 billion in November, valuing the company at $29.3 billion. This marked its second funding round of the year, following a $900 million Series C round in June that valued it at nearly $10 billion. Healthcare AI agent startup Hippocratic AI also completed its second round of 2025, securing $126 million in November at a $3.5 billion valuation, after an earlier $141 million Series B round.
Other significant capital injections include Reflection AI, which raised a $2 billion Series B round in October led by Nvidia, valuing the company at $8 billion, as its second mega-round of the year. AI research lab Anthropic secured a $13 billion Series F round in September, valuing it at $183 billion, following a $3.5 billion Series E round in March. OpenAI raised a record-breaking $40 billion funding round in March, pushing its valuation to $300 billion.
Companies focusing on AI infrastructure and enterprise software also saw substantial investment. Celestial AI raised a $250 million Series C round, valuing it at $2.5 billion, while Uniphore, an enterprise AI startup, achieved a $2.5 billion valuation after a $260 million Series F round that included investors like Snowflake Ventures and Nvidia. These funding activities demonstrate sustained investor interest across diverse AI applications and foundational technologies.
