Walmart Added to Nasdaq-100 After Primary Listing Transfer, Replacing AstraZeneca

Walmart Inc. was added to the Nasdaq-100 Index effective January 20, 2026 following the company’s transfer of its primary listing to Nasdaq late in 2025. The move placed Walmart in the index’s composition and resulted in AstraZeneca being removed from the Nasdaq-100 when the change took effect prior to market open on January 20.

Index inclusion is primarily a market-structure event, but it has concrete implications for workers who hold Walmart stock directly or through workplace plans. When a large-cap company joins a major index like the Nasdaq-100, funds that track that index typically adjust holdings to match the new composition. That can prompt purchases by passive funds and ETFs, broadening stock-ownership breadth and temporarily increasing investor attention. For employees, broader ownership can mean greater liquidity in any company stock they hold, and it can influence the short-term valuation of stock-based compensation, restricted stock units, and employee share purchase plans.

Changes to index status also affect retirement plan lineups and corporate messaging. Human resources and benefits teams should expect increased questions from colleagues about 401(k) allocations, company stock exposure, and the potential tax or timing implications of exercising equity awards. Investor relations work can pick up as analysts and index-aware investors reassess Walmart’s role in benchmark portfolios, and recruiting teams may find it easier to cite inclusion in a major technology-weighted index as a point of prestige for candidates who care about stock compensation.

The Nasdaq-100 addition came amid other market and corporate developments for Walmart, including PhonePe IPO progress and Marketplace initiatives. Those items speak to Walmart’s broader strategy of expanding digital and payment services, which helps explain why the company sought a Nasdaq listing and why index providers moved to include it.

For store-level and corporate employees, the operational day-to-day will not change because of index status, but the financial backdrop around compensation and benefits could. Workers who hold Walmart stock or participate in equity plans should review their positions and plan materials, and benefits teams should prepare clear guidance on any questions. Monitor communications from Walmart’s investor relations and human resources departments for specific guidance on plan impacts.

In the weeks ahead, watch for passive fund rebalancing flows and any corporate announcements that could affect valuation. Inclusion in the Nasdaq-100 is a signal that Walmart occupies a different slot on institutional investors’ dashboards, and that shift matters for the financial side of working at the company even as store operations continue as usual.
