Your Data, Their Profit: the Senate's first hearing on AI surveillance pricing

The first Senate hearing devoted squarely to surveillance pricing, with witnesses from UFCW, MIT, Wharton, and Groundwork Collaborative and concrete examples: Staples charging more by IP address, and one Kroger shopper's 62-page personal profile. Hawley chaired, called the practice 'the unholy trinity of everything America hates,' and says a bill is coming.

New Jersey sends surveillance-pricing ban to the governor

The Fair Price Protection Act cleared both chambers June 30, barring grocery stores and delivery platforms from using AI and consumer surveillance data to price the same item differently, plus a one-year moratorium on new electronic shelf labels. It now awaits Gov. Sherrill, who has signaled support.

Jul 1, 2026·Tennessee General AssemblyRegulation & Litigation

Tennessee's ban on personalized algorithmic pricing takes effect

SB1807 took effect July 1, making Tennessee's ban on personalized algorithmic pricing the first of the 2026 state bans to actually bite. Violations count as unfair or deceptive acts under the state's Consumer Protection Act, with carve-outs for insurers, regulated lenders, and subscription discounts.

Jun 10, 2026·New York Attorney GeneralRegulation & Litigation

New York passes the One Fair Price Act

New York's legislature passed the first-in-the-nation One Fair Price Act (S.8623B/A.9349B), which bans surveillance pricing and authorizes the attorney general to enforce it as an unfair and deceptive practice. It now awaits Governor Hochul's signature; New York would become the third state to advance a ban after Maryland and Connecticut.

Washington Post sued over subscriber ‘surveillance pricing’

A proposed D.C. class action alleges The Post built ‘pricing profiles’ from subscribers’ reading habits to set individualized renewal prices, disclosing the practice only after New York’s pricing law required it. The first time surveillance pricing has reached a marquee consumer brand in court rather than a regulator’s study.

Yes to California’s Bill to Ban Surveillance Pricing

EFF formally backs California’s AB 2564, which would bar retailers from setting customized prices off a shopper’s personal data and give consumers a private right to sue. The clearest privacy-first case yet against surveillance pricing as the bill heads to the state Senate.

WalmartPublished March 2026

Machine Learning Demand Prediction and Price Recommendation Using Third-Party Data

US12572954B2 · Google Patents ↗

A machine learning model trained on purchase history, payment methods, customer identification, and third-party data sources to predict item demand and generate recommended prices. The schematic in the filing explicitly shows third-party data as an input to the pricing engine — making this the more controversial of Walmart's two 2026 pricing patents, directly analogous to airline surveillance pricing that uses consumer identity signals to set fares. Where US12524776B2 automates markdown timing, this patent closes the loop by incorporating outside behavioral data to calibrate what price a given consumer will bear.

WalmartPublished January 2026

System and Method for Dynamically and Automatically Updating Item Prices on E-Commerce Platform

US12524776B2 · Google Patents ↗

A machine learning system that uses price elasticity data and predicted demand to automatically generate markdown prices across Walmart's e-commerce platform. The patent covers two model paths: a primary model that fires when both elasticity and demand data are available (enabling precise per-item optimization), and a decay-rate fallback for when they are not — both bounded by configurable upper and lower price limits. Walmart publicly characterizes this as a 'markdown tool' rather than a dynamic or personalized pricing engine, but the underlying data infrastructure — per-item elasticity modeling, real-time demand signals — would make consumer-characteristic pricing technically feasible at scale. This is one of approximately 50 US patents Walmart secured in 2026.

JDA Software GroupPublished June 2019

Travel price optimization (TPO)

US10332134B2 · Google Patents ↗

A revenue-management engine that applies price-sensitive demand forecasting to set dynamic prices across travel and hospitality inventory — hotel rooms, car rentals, passenger transport, air cargo. It models how demand responds to price at a granular, time-sensitive level and recommends the revenue-maximizing price as conditions shift. One of the commercial dynamic-pricing engines that long predate the current surveillance-pricing debate.

Uber TechnologiesPublished May 2019

Facilitating direct rider driver pairing for mass egress areas

US10304277B2 · Google Patents ↗

Coordinates rider–driver matching around mass-egress venues such as stadiums and concerts and applies a price multiplier — a surge price — to those high-demand locations. The system ties pricing directly to a real-time supply–demand imbalance at a specific place and moment. Surge pricing expressed as location-aware demand response.

IndividualPublished February 2019

Dynamic repricing of an online subscription

US10198756B2 · Google Patents ↗

Automatically adjusts the price of an online subscription over time based on usage and engagement signals. Pricing becomes a moving target tuned to each subscriber's behavior rather than a fixed published rate.

IndividualPublished April 2017

Real-time dynamic pricing system

US20170109767A1 · Google Patents ↗

A real-time pricing system that ingests live market and competitor signals — including prices scraped from competitor webstores — and computes an optimal price per product on the fly. Illustrates how automated competitor monitoring became a standard input to dynamic pricing.

Solum Co LtdPublished September 2016

Electronic shelf label tag, electronic shelf label system for time-division transmission of display data and change command data, and operating method thereof

US9454919B2 · Google Patents ↗

An electronic shelf label system that schedules and pushes display and price-change data to in-store tags over a time-division wireless channel. It is the physical delivery layer for dynamic pricing — the mechanism that lets a retailer change a shelf price centrally and instantly. The same class of infrastructure now at the center of the digital-shelf-label and surveillance-pricing backlash.

International Business MachinesPublished April 2015

Personalized pricing for omni-channel retailers with applications to mitigate showrooming

US20150100384A1 · Google Patents ↗

Computes individualized prices for omni-channel retail by modeling a shopper's purchase history and willingness to wait, predicting the probability they buy now versus later, and pricing to convert them — explicitly to counter 'showrooming.' Consumer-characteristic personalized pricing, the contested kind, described plainly in 2015.

QualcommPublished August 2014

System and Method For Providing A Personalized Shopping Experience and Personalized Pricing of Products and Services With A Portable Computing Device

TravelClickPublished August 2014

Methods and systems for setting optimal hotel property prices

US20140222518A1 · Google Patents ↗

Sets dynamic hotel room prices for transient demand, raising or lowering rates as booking pace and remaining supply change in order to maximize revenue. Classic hospitality revenue management — market-condition dynamic pricing rather than personalized pricing.

Pricer ABPublished July 2014

Method and arrangements for electronic shelf labels

US20140214620A1 · Google Patents ↗

Methods and arrangements for wirelessly changing the price and information shown on electronic shelf labels from a central pricing application. Part of the ESL infrastructure that makes frequent, centrally controlled price changes operationally trivial.

A method for repricing marketplace listings to gain or hold competitive advantage, automating the research of comparable listings to find an optimal price. Captures the automated-repricing dynamic that drives e-commerce price volatility.

Overstock.comPublished March 2014

Pricing and forecasting

US8676632B1 · Google Patents ↗

A pricing-and-forecasting system with an elasticity module that computes price elasticity from historical sales — the ratio of demand change to price change — to guide pricing decisions. Elasticity modeling is the quantitative core that turns raw sales data into a dynamic price.

SafewayPublished March 2014

Adaptable retail pricing environment and electronic exchange, delivering customized buyer promotion rewards and discounts

US8671018B2 · Google Patents ↗

An individualized discount-and-reward server tied to a retailer loyalty program, delivering customized per-buyer promotions and prices from stored customer data. Personalized pricing routed through loyalty data — a grocery-retail antecedent of today's surveillance-pricing concerns.

Opera SolutionsPublished February 2014

System and Method for Demand Forecasting

US20140039979A1 · Google Patents ↗

A demand-forecasting system that incorporates price elasticity of demand to improve prediction accuracy and enable price optimization and inventory management. The forecasting-plus-elasticity engine that sits underneath automated price-setting.

US AirwaysPublished December 2013

Dynamic cost analysis and overbooking optimization methods and systems

US8600787B2 · Google Patents ↗

Determines the revenue-optimal number of airline seats to sell using probabilistic demand distributions and passenger history, optimizing overbooking and fare mix. Airline revenue management — the discipline from which much of retail dynamic pricing descends.

Oracle InternationalPublished October 2013

Time-dependent product pricing optimizer

US20130275183A1 · Google Patents ↗

A time-dependent product pricing optimizer that sets prices as a function of time and demand conditions. A general-purpose dynamic-pricing engine from a major enterprise software vendor.

Uber TechnologiesPublished October 2013

Enabling a user to verify a price change for an on-demand service

US20130268406A1 · Google Patents ↗

Uber's surge-confirmation mechanism: when prices spike, the rider must actively confirm the multiplier — for example by typing the surge rate — before booking. Notable less for the pricing math than for making real-time, demand-based pricing a visible and explicitly confirmed consumer experience.

Uber TechnologiesPublished September 2013

System and method for dynamically adjusting prices for services

US20130246207A1 · Google Patents ↗

A system for dynamically adjusting the price of on-demand services in response to real-time supply and demand. The core surge-pricing apparatus behind ride-hail dynamic fares.

Amazon TechnologiesPublished November 2006

Dynamic Pricing System

US7133848B2 · Google Patents ↗

Amazon's foundational dynamic pricing patent — the original architecture for adjusting prices in real time based on demand signals, competitor data, and inventory levels. Granted in 2006, this is the upstream ancestor of the entire algorithmic pricing patent landscape now being contested in regulatory proceedings and state legislatures. The infrastructure it describes — continuous price monitoring, automated adjustment triggers, competitive benchmarking — is what the FTC's 2024 surveillance-pricing study characterized as a systemic threat to consumer welfare.
