Oscar Health

Oscar Health is a pioneer in the 'Insurtech' space, operating on a proprietary, cloud-native technology stack designed to replace legacy insurance infrastructure. By 2026, Oscar has solidified its position as a Lead AI-native healthcare platform through its +Oscar business segment, which modularizes its internal technology for third-party providers and payers. The platform’s architecture leverages large language models (LLMs) to automate claims processing, documentation, and member engagement. At its core, Oscar utilizes a centralized data ecosystem that integrates clinical data, claims, and member interactions to provide real-time care recommendations. Their 'Campaign Builder' tool utilizes predictive modeling to identify at-risk members and trigger personalized health interventions. In the 2026 market, Oscar stands out by moving beyond traditional insurance into a 'platform-as-a-service' model, focusing on reducing administrative overhead through automated prior authorizations and an AI-assisted member app that functions as a first-line virtual triage system.
