There are "legitimate concerns around the consumer experiences" of buying tickets for Oasis concerts at the weekend, the Competition and Consumer Protection Commission (CCPC) has said, and it is "actively reviewing the situation".
The band announced 17 shows in the UK and Ireland, with the first due to take place in Cardiff in July 2025, followed by nights in Manchester - where the band was formed in 1991 - London, Edinburgh and two dates in Dublin.
All the tickets in Britain sold out in around ten hours on Saturday, after many fans spent the day in online queues.
Many Irish fans were left disappointed that they did not get one of 160,000 tickets on sale over two dates in August 2025 in Croke Park.
Those who waited for hours in online queues to get tickets were shocked at hugely inflated prices by the time they finally got the opportunity to make a purchase.
Tickets were advertised as being priced from €86.50 - subject to service charge - and limited to four per transaction.
However, people reported the price for standing tickets more than doubling from around €176 on pre-sale to over €400.
"We are actively reviewing the situation and we will consider all options to ensure consumer protection law is followed," the CCPC said in a statement.
A statement from Ticketmaster to RTÉ's Today with Claire Byrne progamme said that all prices "are set by the tour".
"All ticket prices, including Platinum, In Demand, and VIP, are set by the tour. Promoters and artists set ticket prices. Prices can be either fixed or market-based. Market-based tickets are labelled as 'Platinum' or 'In Demand'."

Pricing left 'a bad taste' - Taoiseach
The pricing strategy has led to criticism of Ticketmaster and concert promoters MCD and calls for an investigation into Ticketmaster's "in-demand" structure.
Taoiseach Simon Harris said the monopolistic pricing in the ticketing industry should be looked at.
"The monopoly held by one company is something that I think does deserve probing and also the issue around surcharges," he said.
"I think there's a bad taste in the mouths of people here in relation to pricing, surcharge, and we do have to be conscious we are dealing with a monopoly situation here as well."
"I do think this needs to be reviewed and look, if there's actions Government needs to take in terms of the future... let's look at that and let's take action in relation to that."
Minister for Enterprise Peter Burke said he was "committed to ensuring consumers are provided with sufficient pricing information before they choose to purchase a product" and that he had asked the CCPC to report to him on their review of the pricing strategies employed.
Tánaiste Micheál Martin said yesterday that he hoped those behind the ticket sales would "reflect" on what had happened.
The Taoiseach also expressed his hope that Oasis will announce extra Irish gigs because of the demand for tickets.
"I think with the level of interest in attending Oasis gigs in this country, one would hope that they might find it within themselves to put on a few more."
'Needs to stop'
The leader of Sinn Féin has said that working class Oasis fans "who got [the band] where they are" were "thrown under the bus" by a "crazy" ticketing system.
Mary Lou McDonald said that Ticketmaster's dynamic pricing which massively hikes the cost of tickets when demand surges is "completely unfair" and "just needs to stop".
"The working class got them where they are and they're throwing them under the bus," Ms McDonald said of the Gallagher brothers, Noel and Liam.
"It’s crazy that permission would be given for concerts, without any notification as to the cost of tickets."
"Whether it’s Oasis or Taylor Swift, or the Wolfe Tones, or the man on the moon who’s performing, the consumer should know what the price ranges are, that they’re fixed prices, and then everybody tries to get in first and get the tickets that they want.
"About 500 quid, nearly, for a ticket? Come on."
The British government has said that it will investigate dynamic pricing as part of a review into ticket sales.
Britain's Minister for Culture Lisa Nandy said it was "depressing to see vastly inflated prices" on official sites.
"Working with artists, industry and fans we can create a fairer system that ends the scourge of touts, rip-off resales and ensures tickets at fair prices," Ms Nandy said.
Another British government minister, Lucy Powell who is leader of the House of Commons, revealed that she paid €930 for two tickets from an official retailer.
