World Cup fans watched prices move with demand. Shoppers now suspect prices move with the buyer.

Prices that move with demand are an old practice, and the 2026 World Cup showed it at global scale. Prices that differ from one buyer to the next are the newer question, and major retailers say they are not doing it.

When the price follows demand

FIFA advertised group-stage World Cup tickets from $60. When Football Supporters Europe and Euroconsumers filed a complaint with the European Commission on March 24, 2026, the cheapest seat for the final started at $4,185, more than 7 times the cheapest final ticket in Qatar in 2022.[1] The groups said dynamic pricing had been “applied without clear limits, causing costs to surge between sales phases.”[1] FIFA calls its approach variable pricing, meaning prices can rise or drop with demand.[2]

Europe had a reference point. UEFA said in March 2026 that it intends to keep Euro 2028 prices at Euro 2024 levels, with more than 40% of tickets in its two cheapest categories, which were €30 and €60 at Euro 2024.[3] Researchers writing in RTÉ Brainstorm put a Euro 2024 final ticket in Berlin at about €95 and argue that buyers who cannot see how a price was set feel cheated.[4]

Wendy’s offers a smaller case. On a Feb. 15, 2024 earnings call its CEO described testing “dynamic pricing and daypart offerings” on digital menu boards beginning as early as 2025, and headlines compared the plan to ride-share surge pricing. Wendy’s replied within two weeks that its comments were “misconstrued” and that it “would not raise prices when our customers are visiting us most,” saying the boards would instead allow discounts in slower periods.[5]

When the price follows the buyer

Personalization is familiar from social feeds, where an algorithm decides what each person sees. The Wall Street Journal reported on Oct. 25, 2026 that shoppers now suspect retailers and restaurants of applying the same idea to the number on the screen, using AI systems to charge people differently based on who they are or how badly they need something.[6]

The companies deny it. Walmart’s CEO wrote to customers on Sept. 25 that “We price the product, not the person,” and that income, shopping history, and urgency “won’t change the price.”[7] McDonald’s says its franchisees do not use AI to set menu prices.[6] The Journal adds that research on electronic shelf labels in the U.S. and Europe found they do not lead to surge pricing, and that grocers use them mostly to discount food about to expire.[6]

Two sets of findings sit alongside the denials. FTC staff reported in January 2025 that details like a person’s precise location or browser history can be used to target individual consumers with different prices.[8] In December 2025, Consumer Reports and Groundwork Collaborative had shoppers in four cities add the same items to Instacart carts at the same time. Nearly 75% of the items tested showed different prices to different shoppers, with up to five prices for a single item, an average gap of 13% between lowest and highest, and a maximum of 23%.[9] Instacart called the tests randomized, then ended them on Dec. 22, 2025, saying shoppers at the same store at the same time “see the same prices.”[9][10] The FTC documents the tools. The research test on Instacart documents the price differences.

How lawmakers are drawing the line

New York requires companies to disclose when they have used algorithmic pricing, and Maryland, Connecticut, and New Jersey passed laws this year restricting certain kinds of personalized pricing or pricing based on personal data.[6] The FTC proposed an enforcement policy statement this past summer aimed at “any deceptive or unfair personalized pricing.”[6] Colorado’s governor vetoed a similar bill, saying its broad sweep would also punish lower prices.[6]

Student and senior discounts complicate any ban, since they are also prices that differ by buyer.[6]

What a teenager needs to read in a price

Reading a sales price now includes asking what may have moved it.

• A price that follows time or demand moves for everyone looking at the same listing, and a shopper can wait, watch, or compare.

• A price that follows the buyer can differ between two people looking at the same product or service, which makes a second device, a logged-out browser, and a look at the shelf tag worth more thought before a purchase.[9]

The sticker is not always the whole price either: a $0 stock trade still has someone paying for it. The pricing practices come from the same business decision, what a seller can charge and what a buyer will pay. A teenager who has set a price for a product understands why a seller would want to vary the number, and why the price one person sees may not be the price another sees.

Practices like these can change in weeks. Instacart ended its price tests 13 days after Consumer Reports published its findings, a pace a printed textbook cannot match.[9][10] FinBizify is built to keep up with it: lessons start from real companies, real dollar figures, and the latest filings and public data, so they reflect what companies are doing now.
