MODERATE

The bill was renamed from the 'Algorithmic Pricing Transparency Act' to the 'Algorithmic Pricing Prohibition Act,' shifting its focus from requiring businesses to disclose how they set prices to strictly banning the practice of using personal data to generate different prices for different customers. The bill now explicitly defines 'consumer' as an Illinois resident acting in an individual or household context and adds a specific prohibition against using personal data for pricing, whereas the original version only required transparency about such practices.

Scope change

The bill's scope narrowed from requiring transparency for all online sellers to prohibiting surveillance pricing entirely, while also clarifying that the law applies specifically to Illinois residents and excludes standard business practices like supply chain costs or loyalty discounts.

DEFINITION

Added a specific definition for 'consumer' to limit the law's application to Illinois residents acting in an individual or household context, excluding businesses or commercial buyers.

Added a new definition for 'personalized price' to clarify that it is a price set based on a consumer's personal data.

SCOPE

Renamed the bill from 'Transparency Act' to 'Prohibition Act,' changing the legal requirement from merely disclosing pricing methods to strictly forbidding the use of personal data for price discrimination.

REQUIREMENT

Added a new section explicitly prohibiting covered entities from engaging in surveillance pricing, replacing the previous requirement to simply disclose when it occurs.

Replaced the requirement for businesses to provide a 'non-personalized baseline price' upon opt-out with a blanket prohibition on using personal data for pricing in the first place.

Added a new requirement for the Attorney General to conduct annual public education and outreach programs regarding algorithmic pricing practices.

ENFORCEMENT

Removed the specific requirement for businesses to provide a hyperlink explaining their pricing practices, as the practice itself is now banned rather than just disclosed.
