The year 2025 has proven to be a landmark period for artificial intelligence (AI) startups, with a total of 15 companies successfully securing venture funding rounds exceeding $2 billion each. According to data from Crunchbase, these companies collectively raised over $100 billion in financing. A significant portion of this funding was directed towards generative AI firms, which dominated the fundraising landscape.
The largest funding round was unprecedented, as OpenAI announced a record-breaking investment of $40 billion on March 31, 2025. This monumental deal, backed by SoftBank, represents the largest venture investment in history. Details reveal that SoftBank will mobilize a syndicate of co-investors to contribute $10 billion to the total, while the remaining $30 billion is expected to be funded primarily through debt.
