Workday Co-Founder Maintains 7 Trillion Won Stake While Liquidating Hundreds of Billions

Workday, Inc. (NASDAQ: WDAY) co-founder David Duffield converted roughly 100,000 Class B shares into Class A common stock on March 5, 10 and 18, then sold them in multiple open-market transactions under a Rule 10b5-1 trading plan. Over three trades, he netted approximately $14.3 million to $15.6 million per transaction—about $45 million in total (around KRW 60 billion). According to SEC filings, the Duffield Trust still holds tens of millions of Class A shares, representing a stake worth roughly $5.7 billion (about KRW 7 trillion). The transactions are characterized as portfolio and liquidity management rather than a full divestiture.

In its February 24 release of fiscal 2026 fourth-quarter and full-year results, Workday reported double-digit year-over-year subscription-revenue growth, with total revenue and adjusted EPS exceeding market expectations. On February 9, Anil Bhusri was named CEO as Carl Eschenbach stepped down from both the CEO role and the board. A March 6 filing further disclosed that Bhusri received nearly one million RSUs and performance-based RSUs.

Founded in 2005 by David Duffield and Anil Bhusri in Pleasanton, California, Workday is a cloud-based provider of human-capital and financial-management software. Recently, it has positioned itself as an enterprise AI platform, integrating AI capabilities into HR and finance workflows and competing globally with SAP and Oracle.
