Top Gainer

Q1 2026 Analysis

Editorial • LLM Radar Research

Stripe remains the undisputed king of developer-first payments, but the landscape is evolving. Adyen is gaining enterprise market share in AI recommendations, particularly for omnichannel commerce. Square (Block) dominates in-person payment queries. The emerging trend: AI models are increasingly recommending Stripe for its infrastructure play (Atlas, Issuing, Treasury) rather than just payment processing, signaling a shift in how LLMs categorize financial platforms.
