Walmart Inc. will replace AstraZeneca Plc in the Nasdaq 100 Index before the market opens on Jan. 20. The switch comes after Walmart’s move to Nasdaq from NYSE last year. Analysts estimate $19 billion in inflows from index-tracking funds due to Walmart’s inclusion. Walmart’s market value has climbed to nearly $1 trillion.

Walmart has seen steady sales growth and share gains, with its digital operations expanding. The company has increased its use of artificial intelligence in internal operations and for shoppers. Walmart shares have gained 146% in the past three years, while AstraZeneca shares rose 42%.

AstraZeneca’s removal from the index follows a decline from its pandemic-era peak. The drugmaker’s vaccine revenue has faded, and attention has shifted to obesity treatments from rivals. The Nasdaq 100 tracks the largest non-financial companies on Nasdaq, with over $600 billion in assets tracking the index through ETFs as of December 2025.
