Last year was monumental for the AI industry in the U.S. and beyond.

There were 49 startups that raised funding rounds worth $100 million or more in 2024, per our count at TechCrunch; three companies raised more than one “megaround,” and seven companies raised rounds $1 billion in size or larger.

How will 2025 compare? It’s still the first half of the year, but so far it looks like 2024’s momentum will continue this year. There have already been multiple billion-dollar rounds this year, and more AI megarounds closed in the U.S. in Q1 2025 compared to Q1 2024.
