Payments giant Stripe has finalized its acquisition of AI routing platform OpenRouter for over $7 billion, a deal that significantly bolsters Stripe's presence in the artificial intelligence sector. The acquisition integrates OpenRouter's technology, which allows developers to access and manage traffic across more than 400 AI models through a single API endpoint, with Stripe's existing payment processing infrastructure.
This strategic move positions Stripe to play a central role in the burgeoning AI economy, offering businesses enhanced capabilities for AI model cost optimization and flexibility. OpenRouter's platform, which applies a roughly 5% markup on inference spend, had garnered 8 million developers by May 2026, demonstrating substantial growth and market traction.
The acquisition price represents a significant premium, valuing OpenRouter at more than five times its previous valuation of $1.3 billion just three months prior. The final price was reportedly about 30% lower than an initial $10 billion figure, indicating complex negotiations. The deal also brings potential operational complexities for Stripe, including managing billing for model providers and handling models subject to China's National Intelligence Law.
