The American company has given a number of undertakings to the Competition and Markets Authority (CMA) following the conclusion of an investigation it opened in September 2024.

One of the two concerns identified by the CMA was that Ticketmaster did not tell fans waiting in lengthy queues that standing tickets were being sold at two different prices, and that prices would jump as soon as the cheap tickets sold out.

The other was that Ticketmaster sold some ‘platinum’ tickets at almost two-and-a-half times the price of ‘standard’ tickets, without sufficient explanation that these offered no additional benefits over some ‘standard’ tickets in the same areas of the venue.

However, the CMA found that so-called “dynamic pricing” was not used in relation to the Oasis concerts, contrary to some reporting at the time.

Ticketmaster has now agreed to tell fans 24 hours in advance if a tiered pricing system is being used, as it was for Oasis standing tickets. This means fans will know beforehand if there are multiple prices for the same type of ticket, and that more expensive ones will be released once the cheapest sell out.

It will also provide more information about ticket prices during online queues, helping fans anticipate how much they might have to pay.

This includes setting out the range of prices available for the event when people join the queue and updating fans swiftly when the cheaper tickets sell out. Additional information to help fans make the best decisions for them will also be given about the prices of tickets sold using tiered pricing.

Ticketmaster has also agreed not to use any misleading ticket labels, ensuring that tickets are described accurately and do not give the impression that one ticket is better than another when that is not the case.

It will also give regular reports to the CMA over the next two years on how it has implemented the undertakings. Failure to take forward the agreed measures could result in enforcement action, the CMA said.

Sarah Cardell, chief executive of the Competition and Markets Authority, said: “Fans who spend their hard-earned money to see artists they love deserve to see clear, accurate information, upfront.

“We can’t ensure every fan gets a ticket for events as popular as the Oasis tour, but we can help ensure that next time an event like this comes along, fans have the information they need, when they need it.

“The changes we’ve secured will give fans more information about prices and clear descriptions of exactly what they are getting for their money.

“If Ticketmaster fails to deliver on these changes, we won’t hesitate to take further action.”

A spokesperson for Ticketmaster said: “We welcome the CMA’s confirmation there was no dynamic pricing, no unfair practices and that we did not breach consumer law.

“To further improve the customer experience, we’ve voluntarily committed to clearer communication about ticket prices in queues.

“This builds on our capped resale, strong bot protection, and clear pricing displays – and we encourage the CMA to hold the entire industry to these same standards.”
