The AI industry entered 2025 with strong momentum. According to our count at TechCrunch, 49 startups raised funding rounds worth $100 million or more in 2024. Within that group, three companies raised more than one mega-round, and seven companies raised rounds of $1 billion or larger.
The industry did not slow down in 2025. While fewer companies raised rounds larger than $1 billion, four companies did so, with Anthropic raising two rounds over $1 billion. Significantly more companies raised multiple rounds compared to 2024, with eight achieving this milestone versus the previous year’s three.
How will 2026 compare? The first few weeks of the year already show signs of another strong period. Elon Musk’s xAI announced a $20 billion Series E round, and Sam Altman’s brain-computer interface startup Merge Labs raised a $250 million seed round with OpenAI as the lead investor. Of course, it is still early, and we will be watching to see if the momentum continues.
