Maryland enacted the first statewide ban on surveillance-based dynamic pricing in the retail sector. This law directly impacts Walmart’s in-store and online pricing systems. The restrictions take effect on October 1, 2026.

The legislation prohibits retailers from using personal data to set individualized prices for goods. This development challenges the industry trend of leveraging customer data for price optimization.

Investors face potential strategy shifts as other states may adopt similar legislation. Major retailers must now evaluate compliance costs and potential overhauls to their data technology.
