Workday shares plunged 9% after CEO Carl Eschenbach revealed that OpenAI and Google have adopted its finance and HR software. The slide underscores investor concerns over revenue concentration with major AI clients and uncertainty around subscription renewal growth.

1. Stock Plummet After Major Client Reveal

Workday shares tumbled 9% in afternoon trading when CEO Carl Eschenbach disclosed that AI leaders OpenAI and Google are running its finance and HR applications. The rapid selloff erased billions in market value and marked the steepest one-day drop since last quarter’s earnings announcement.

2. Investor Concerns Over Client Concentration

Market participants flagged that reliance on a handful of large AI-focused customers could introduce volatility in renewal cycles and subscription bookings. Analysts warned that unexpected disclosures about high-profile clients may pressure the company’s visibility into long-term growth prospects.
