Illinois House Bans AI‑Driven Personalized Pricing by 78‑19 Vote

Context Illinois lawmakers moved Friday to curb a pricing practice that uses personal data to set different prices for the same product. Companies collect details such as browsing history, purchase patterns, device type and location, then feed the data into algorithms that calculate a unique price for each shopper. Critics argue the practice lacks transparency and can charge higher‑paying customers more without their knowledge.

Key Facts House Bill 4248 passed the lower chamber by a 78‑19 margin, making it the first state legislation to outlaw AI‑generated personalized pricing. Rep. Maura Hirschauer warned that the technology can silently charge two people sitting side by side different amounts for the same item, calling the practice “not transparency, not fairness.” The bill was drafted with input from the Illinois Retail Merchants Association and the Illinois Manufacturers' Association, groups that say consumers deserve consistent pricing.

Rep. Jeff Keicher raised concerns that the ban could ripple through financial services and insurance, sectors that already rely on individualized algorithms for credit scoring and risk assessment. He cautioned that disrupting those formulas could affect loan decisions and insurance underwriting, which often depend on large, data‑driven models.

The measure now heads to the Illinois Senate for further consideration. If enacted, companies would be prohibited from using AI software to set prices based on personal data, forcing them to adopt uniform pricing structures for identical goods and services.

What It Means Consumers could see more consistent price tags across retailers, reducing the risk of hidden surcharges tied to online behavior. Businesses will need to redesign pricing strategies, potentially shifting to cost‑plus or market‑based models that do not rely on individual data points. Financial institutions may seek exemptions or new regulatory guidance to maintain risk‑based pricing that complies with the law.

Watch for the Senate’s response and any carve‑outs that could preserve algorithmic pricing in regulated sectors such as banking and insurance.
