AI Healthcare Stocks Surge Over 5% Amid Share Buyback Momentum

Waystar Holding Corp. (NASDAQ: WAY), an AI-powered healthcare payment software company, closed at $20.60 on the Nasdaq on June 4, up 5.51%. Trading volume was approximately 1.3 million shares, and the company’s market cap climbed to about $3.9 billion—roughly KRW 5.5 trillion—adding some $230 million (around KRW 320 billion) in a single day.

The stock has continued its upward momentum following a Q1 2026 earnings surprise and the announcement of a $200 million (about KRW 280 billion) share repurchase program, boosting investor confidence in the growth potential of its AI-based revenue cycle management platform. Meanwhile, Waystar’s AI solution, AltitudeAI, was recently ranked first in the healthcare revenue cycle management segment in an industry survey, further underscoring the company’s AI competitiveness.

Headquartered in Lehi, Utah, Waystar provides a cloud-based platform that automates billing, collections, denial management, and data analytics for hospitals and clinics. The company went public on the Nasdaq in 2024 and completed the acquisition of Iodine Software in 2025, enhancing its offering into an integrated AI healthcare payment platform by unifying clinical and financial data.
