US startup funding experienced a significant resurgence in the first half of 2025, according to PitchBook data reported by Reuters. Funding surged by 75.6% year-over-year, reaching $162.8 billion – the strongest performance since the first half of 2021. This growth is primarily attributed to the ongoing boom in artificial intelligence (AI) investments. If the current trend continues, 2025 is projected to be the second-best year on record for US startup funding. This positive momentum signals renewed investor confidence and a vibrant innovation ecosystem.
