OpenAI Continues to Lead
At the top of the list is OpenAI, with a massive $40 billion funding round that puts its valuation at $300 billion.
The round is backed by names like Microsoft and SoftBank, but has a major stipulation: OpenAI must transition from its current hybrid nonprofit structure to a fully independent for-profit entity by Dec. 31, 2025.
Shortly after the deal was announced, OpenAI stated it would remain under the control of its nonprofit parent, while restructuring its for-profit arm to be able to raise more capital. Lead investor, SoftBank, says it will reduce its contribution to $20 billion from $30 billion if the transition does not happen on schedule.
Scale AI’s Strategic Expansion with Meta
Meta invested $14.3 billion in ScaleAI in June 2025, acquiring a 49% non-voting stake and increasing the firm’s valuation to $29 billion.
Critically, the deal means Scale CEO Alexandr Wang will transition to Meta to co-lead its Superintelligence Lab, a newly created AI division that will centralize Meta’s AI research and development.
Specialized Startups Raise Billions
Lesser known startups like Infinite Reality and Safe Superintelligence also secured multibillion-dollar rounds.
Infinite Reality, which has raised $3 billion so far this year, is capitalizing on the growing demand for immersive experiences. The company builds virtual environments that integrate entertainment, e-commerce, and social interaction—targeting brands and creators looking to engage audiences in novel digital spaces.
Safe Superintelligence, on the other hand, focuses on AI alignment and long-term safety. Founded by ex-OpenAI researchers, the startup is pursuing a focused mission: building a superintelligence that is safe by design.
