MARI

Global operator of high-profile live events

Overview

MARI owns and operates a global portfolio of high-profile live events across sports, art and lifestyle. It earns revenue by acquiring and managing events and brands (such as the Miami Open, Frieze fairs, and Barrett-Jackson), then coordinating operations, marketing, sponsorships, and hospitality to attract fans, sponsors, and media rights. Unlike firms focused on a single sector, MARI bundles multiple categories under one umbrella, backed by a broad investor group, to cross-promote and grow audiences. Its goal is to turn growing demand for live experiences into a leading global platform that delivers large audiences, sponsors, and media value.

Simplify's take

What believers are saying

  • MARI signed ATG on August 11, 2026, adding 70 venues and 18 million annual attendees.
  • Bucket Listers and Viva.com broaden audience acquisition and payment capture across five UK events.
  • Frieze, Miami Open, and Hyde Park Winter Wonderland provide recurring premium inventory and sponsorship revenue.

What critics are saying

  • ATG closes only after regulatory approval, leaving a multibillion-dollar deal execution risk.
  • MARI depends on luxury discretionary spending; a live-ticket downturn would hit every portfolio asset.
  • If antitrust scrutiny targets Emanuel's live stack, expansion into venues and ticketing stalls.

What makes MARI unique

  • Ari Emanuel built MARI as a multi-asset live-experiences rollup since October 2025.
  • MARI owns tennis, Frieze, TodayTix, and ATG across sports, art, and theatre.
  • Its stack spans discovery, ticketing, venues, and production across global premium audiences.

US pop star Alex Warren to headline UK festival next year.

US pop star Alex Warren to headline UK festival next year. 23rd October American pop sensation Alex Warren is set to headline a major UK festival in 2027. The Grammy-nominated singer-songwriter will take the stage at Blenheim Palace Festival on Sunday, June 27, as part of his Finding (More) Family on the Road World Tour. His performance will mark a standout night at the open-air concert series, held against the backdrop of the historic palace in Woodstock, Oxfordshire. His 2025 single Ordinary became a 7x-Platinum hit, spending 10 weeks at No.1 on the Billboard Hot 100 and 13 weeks at the top of the UK Songs Chart. It was the top-selling song of the year, propelling him into the global spotlight. In August 2026, he released his second album, WILDCHILD, which topped charts in both the UK and US. Warren has also made a name for himself as a live performer, selling out arena tours worldwide and appearing at major award shows, including the Grammys, MTV VMAs, and American Music Awards. Blenheim Palace Festival (Image: Blenheim Palace Festival) Peter Taylor, co-founder of Cuffe & Taylor, said: "Herald Series is delighted to be bringing Alex Warren to Blenheim Palace in 2027. "He's one of the biggest new stars on the planet right now and, after the year he's had with Ordinary and a No.1 album, there really couldn't be a better way to kick off its second year. "Its debut summer was incredible and the feedback from fans was fantastic. "This is just the start of what we have planned for 2027 and there's plenty more to come." Katy Perry (Image: PA) The 2026 edition of the festival featured headline performances from Katy Perry, Michael Bublé, Alanis Morissette, Teddy Swims, and Pete Tong Ibiza Classics. Teddy Swims (Image: Lucy North / PA) Stephen Flint Wood, EVP and group managing director at MARI Arts & Entertainment, said: "Alex has captivated audiences with his distinctive pop sound and universally relatable songs. "His remarkable trajectory and growing international appeal make him an exciting artist to lead this year's announcement. "We look forward to building on the festival's foundations, bringing world-class live music to the extraordinary setting of Blenheim Palace, with many more standout acts still to be announced." (Image: Jim Cooke / Blenheim Palace Festival) Warren has partnered with PLUS1 to donate £1 from every ticket sold to support children's hospitals in the communities where he performs. Tickets for Alex Warren's headline show at Blenheim Palace Festival go on general sale at 9am on Friday, October 30, 2026. Pre-sale tickets will be available from Tuesday, October 27. The Blenheim Palace Festival is a collaboration between live music promoters Cuffe & Taylor and events producers MARI Arts & Entertainment. Heather Carter, managing director of heritage business at Blenheim Palace, said: "Last summer, the Great Court was filled with incredible music and an amazing atmosphere. "Welcoming Alex Warren as the first headliner for 2027 is a wonderful way to build on a phenomenal first year of Blenheim Palace Festival. "There's nothing quite like watching the sun set over the Palace with thousands of fans singing along, and we can't wait to share that experience next summer."

Rich boys buy big toys.

Rich boys buy big toys. Broadway tickets: $130. Lakers tickets: $702. Buying one of the biggest Broadway and West End landlords or the whole damn Los Angeles Lakers: priceless billions and billions of dollars. Some of Hollywood's foremost hoarders of obscene wealth went on shopping sprees this week, snapping up cultural institutions as though they were Pokémon trading cards. On Tuesday, The Wall Street Journal reported that the Ari Emanuel-owned Mari Group has made a deal to buy ATG Entertainment for $6 billion. ATG owns and manages dozens of theaters worldwide, including ten West End venues and seven Broadway venues housing shows like Titaníque, The Book of Mormon, Hadestown, Harry Potter and the Cursed Child, and the upcoming Paddington. Emanuel, who is best known as a Hollywood mogul and CEO of WME, is also the CEO of UFC and WWE. On the surface, Broadway musicals don't have too much in common with mixed martial arts, but Emanuel calls the acquisition "a long-term bet on where live goes next." If you thought that was steep, former Disney CEO Bob Iger and Josh "Jared's brother" Kushner have gone in together on a deal that makes Emanuel's ATG acquisition look like a Shein haul. Variety confirmed today that the duo is buying the L.A. Lakers for $12.5 billion. "Our long-term commitment is to build on that foundation, compete at the highest level, and serve this extraordinary team, its fans, and the city of Los Angeles," the duo said in a joint statement. Karlie Kloss has yet to comment on her husband's midlife crisis splurge. Yesterday, the BBC reported that a Jeff Bezos-affiliated consortium is looking to buy a 30 percent stake in Liverpool FC, which, by rule of three, makes these big billionaire buyouts a trend and Rob McElhenney a trendsetter.

ATG Entertainment acquired by Mari.

ATG Entertainment acquired by Mari. A big move in the industry 11 August 2026 ATG Entertainment has been acquired by Mari. Ari Emanuel's global events and experiences company has entered a definitive agreement to acquire the West End and Broadway theatre company. The financial terms of the agreement, which sees Mari acquiring the theatre owner from private equity firm Providence Equity, were not disclosed. The transaction is subject to regulatory approvals and customary closing conditions, and as such, until completion, Mari and ATG will continue to operate as separate companies. ATG operates a portfolio of 70 venues across the United Kingdom, the United States, Germany, and Spain, including seven on Broadway and ten in London's West End, as well as an extensive network of regional theatres. Combined, its venues host over 16,000 performances and welcome over 18 million audience members each year, and it produces and co-produces work for the West End and Broadway. Mari owns and operates a global portfolio of events and experiences across sports, art, entertainment and lifestyle. In the UK, these include Hyde Park Winter Wonderland and the Hampton Court Palace and Blenheim Palace Festivals. It recently acquired TodayTix. Following completion, the company intends to act as a long-term custodian of ATG's theatres, investing in their preservation and modernisation as well as improving audience experience and providing support for new productions. Emanuel, founder and principal investor of Mari, said: "I've spent my whole career in entertainment, and I started out in theatre. I've seen the industry reinvent itself many times, but live has only grown more powerful. Nothing connects great talent with audiences more directly. ATG has built one of the world's great theatre businesses around that experience. This is a long-term bet on where live goes next." Melanie Smith, global chief executive, ATG Entertainment, said: "Mari understands live entertainment and what matters most to ATG: our theatres, the people behind them and the relationships we have built with producers, artists and audiences. That makes Mari the right home for our next chapter. We look forward to this new era and thank Providence for their unwavering support over the past thirteen years." Producer Sonia Friedman added: "As a producer, I have always believed in the power of live theatre to bring people together, challenge perspectives and create unforgettable shared experiences. Our industry has always needed partners prepared to think long term, invest with confidence and support creativity with real ambition. What I find compelling about Mari is its breadth of experience across live events and its respect for creative independence. That combination gives us the chance to champion bold new work, reach broader and more diverse audiences and strengthen the future of live theatre for generations to come." The Raine Group and Moelis and Company acted as financial advisors, Akin Gump Strauss Hauer and Feld LLP acted as legal advisor, and EY acted as tax advisor to Mari. LionTree served as lead financial advisor and Kirkland and Ellis LLP served as legal counsel to ATG and Providence. Goldman Sachs, Jeferies and Barron International Group also served as financial advisors to ATG and Providence.
