K25.ai doubles valuation to $200M in quick Series A re-raise

AI-native prediction market K25.ai has closed a Series A round led by Amber Group, doubling its valuation to $200 million. The startup runs an AI-driven platform that lets users predict outcomes in sports, esports, and entertainment.

The Series A follows closely on K25.ai's Pre-A round, which was led by NewGenIVF Group. The rapid re-raise signals investor appetite for the company just months after its earlier financing.

K25.ai will use the funding for global expansion and product development. The capital also targets its market infrastructure, liquidity strategies, and ecosystem growth.

A back-to-back raise at a doubled valuation points to fast-moving investor interest in AI-powered prediction markets — a niche where machine-driven forecasting meets consumer betting on sports and entertainment.
