Top Stories

1. Ramp raises $750 million at a $44 billion valuation

  • TechCrunch · 2026-06-04
  • Summary: Corporate spend-management startup Ramp announced a $750 million funding round valuing the company at $44 billion. The round was led by ICONIQ, GIC, and Ontario Teachers’ Pension Plan, with additional backing from Goldman Sachs Alternatives, D.E. Shaw, Morgan Stanley Investment Management, Generation Investment Management, Insight Partners, and BroadLight Capital.
  • Why It Matters: The size and pricing of the round reinforce that late-stage capital is still flowing aggressively to fintech platforms that can pair strong revenue growth with an AI narrative. It also signals that investor appetite has returned for scaled private fintech leaders.

2. Helion raises $465 million to finance its fusion power push

  • TechCrunch · 2026-06-04
  • Summary: Fusion startup Helion raised $465 million in a new Series G round at a reported $15.5 billion valuation. Thrive Capital led the financing, with participation from both new and existing backers as the company works toward deploying its first commercial power plant tied to its Microsoft agreement.
  • Why It Matters: This is one of the largest recent climate-tech financings and shows investors are again willing to fund capital-intensive frontier technologies when there is a credible commercialization path. The Microsoft-linked offtake angle also makes this a notable benchmark for deep-tech financing.
