AI-Driven Dynamic Pricing in Retail and Food Delivery Under Legislative Scrutiny
Instacart deployed AI algorithms that charged customers different prices for identical groceries at the same stores, with some shoppers paying up to 23 percent more based on the system's assessment of their willingness to pay. The company halted the experiments in December 2024 after a Consumer Reports investigation, prompting multiple states to propose legislation restricting dynamic pricing.
What happened
Instacart conducted AI-driven pricing experiments across Albertsons, Costco, and Kroger that charged different customers different prices for identical groceries, with price differences reaching 23 percent for the same items at the same store.
The pricing variations were deliberate calculations based on AI algorithms analyzing customer behavior and willingness to pay, described as 'smart rounding' and varying discount displays that created what critics call 'fictitious pricing.'
In December 2024, Instacart halted the controversial price tests following a Consumer Reports investigation.
Reported impact
Customers were charged significantly different amounts for identical products depending on the algorithm's assessment of their willingness to pay, with some paying up to 23 percent more than other shoppers buying the same items at the same location.
Over 39 percent of retailers now use real-time AI pricing systems employing electronic shelf labels and algorithms analyzing weather patterns, inventory levels, competitor pricing, and demand fluctuations.
Index analysis
The incident involves AI systems using personal data and behavioral analysis to determine individualized prices, raising concerns about consumer manipulation and unfair pricing practices.
Multiple states have introduced or are considering legislation to address algorithmic and dynamic pricing, including Pennsylvania's Senate Bill 1205, which would prohibit dynamic pricing of essential goods or services. New York's Algorithmic Pricing Disclosure Act, which went into effect in November, requires businesses engaging in algorithmic pricing to disclose that prices were set by algorithms using personal data.
Governance controls
Pennsylvania Senate Bill 1205 proposes prohibiting 'unfair methods of competition and unfair or deceptive acts or practices' by banning dynamic pricing—changing prices of essential goods within 24 hours based on demand or other factors including AI.
Other states including Arizona, Florida, Hawaii, Illinois, Kentucky, Nebraska, Oklahoma, Tennessee, Vermont, Virginia, and Washington are considering legislation concerning surveillance pricing.
