"Baseline price" does not include a higher price for goods or services made available to consumers by a covered entity for the purpose of offering a lower price through surveillance pricing or algorithmic pricing. "Baseline price" does not include any additional fees for premium or additional features.Algorithmic Pricing Transparency Act § 10 for a specific consumer is personalized and generated using surveillance pricingSurveillance pricing"Surveillance pricing" means algorithmic pricing that uses a consumer's personal data to generate a personalized price increase. "Surveillance pricing" does not include any methods of lowering the baseline price for goods or services, including, but not limited to: (1) the application of any discounts, coupons, promotional offers, rebates, limited-time sales, loyalty or club member pricing, or other reductions or incentives offered to the consumer that lower the total amount the consumer pays; (2) price comparison tools, competitor price matching, or other comparison-based pricing mechanisms; or (3) any other price reduction method that does not increase the baseline price to the consumer.Algorithmic Pricing Transparency Act § 10. The disclosure must state: THIS PRICE WAS SET BY AN ALGORITHM USING YOUR PERSONAL DATAPersonal data"Personal data" means information linked or reasonably linkable to a consumer, including, but not limited to, browsing history, search queries, geolocation data, prior purchases, digital identifiers, or demographic profile data.Algorithmic Pricing Transparency Act § 10. (b) The disclosure required under subsection (a) shall be considered proximate to the pricing information if it is presented next to the price, at the point of checkout, or through a notice presented before completion of the transaction.

Section 15 imposes the bill's core transparency obligation: whenever a covered entity has personalized a consumer's baseline price using surveillance pricing, it must display a clear and conspicuous disclosure containing the prescribed statutory text — "THIS PRICE WAS SET BY AN ALGORITHM USING YOUR PERSONAL DATA."

Subsection (b) deems the disclosure proximate if presented next to the price, at checkout, or via a notice before transaction completion. The mandated language is a verbatim statutory string, leaving no room for euphemistic alternatives.

Section 20 grants consumers a right to opt out of surveillance pricing and obligates covered entities to honor opt-out requests by providing a non-personalized baseline price. This is a data-control right targeted specifically at automated personalized pricing, distinct from broader privacy opt-out rights.

Subsection (a) maps cleanly to CP-01.10 (protected-class data restrictions in algorithmic pricing). Subsections (b) and (c) reinforce the consumer-protection backbone of the Act.

The conforming amendment to the Consumer Fraud and Deceptive Business Practices Act extends liability to a covered entity that materially contributes to, induces, or otherwise facilitates a violation of the Algorithmic Pricing Transparency Act after obtaining actual knowledge of the violation. A safe harbor protects entities that lack actual knowledge, do not willfully disregard red flags, and act expeditiously to remove or disable access to (or notify the responsible party about) the offending price upon learning of the violation.

This is a notice-and-action obligation styled on DMCA § 512 — entities have an affirmative duty to take expeditious action upon obtaining actual knowledge or written notice of unauthorized algorithmic pricing activity.

Section 30 enumerates extensive carve-outs preserving cost-driven price changes, geographic cost variations, supply-chain-driven changes, time-limited sales, taxes and third-party fees, loyalty programs, eligibility-based discounts, and any other bona fide non-discriminatory price change. Subsection (b) confirms the Act does not apply to algorithmic pricing models that do not use personal data, including aggregate market-demand-based models. Subsection (c) exempts insurers (and their affiliates and AI systems) and providers of financial services. The section creates no new compliance obligation; it bounds the scope of obligations imposed elsewhere.

Enforcement

Section 35 routes enforcement through the Consumer Fraud and Deceptive Business Practices Act, granting the Attorney General all remedies, penalties, and authority available under that Act. This is a pure enforcement-channel provision; it imposes no independent compliance obligation on covered entities.
