Ari Emanuel's live events holding company MARI acquired a majority stake in Bucket Listers, a six-year-old event marketing firm that has built relationships with Nike, Amazon, and American Express. The transaction closed without disclosed terms, but Bucket Listers has managed an estimated $50 million in cumulative event spend since founding in 2018. Emanuel departed Endeavor in April 2025 after selling the company to Silver Lake for $13 billion, then launched MARI four months later with backing from private equity firm TPG.
Bucket Listers operates as a white-label production partner for brands requiring ground logistics, talent coordination, and activation design at tentpole events. The firm managed hospitality builds at the last three Super Bowls, constructed branded lounges at Coachella for two consecutive years, and executed Amazon's Prime Day street activations across seven U.S. cities in 2024. Founder Sarah Kunst retains her role as CEO and will join MARI's operating council. The firm employed 42 full-time staff as of January 2026, with seasonal contractor networks scaling to 200+ for major builds.
The acquisition gives Emanuel control of end-to-end activation capabilities he could not directly own at Endeavor due to conflicts with IMG, WME Sports, and 160over90. MARI now holds stakes in three live event businesses: a concert touring logistics platform acquired in October 2025, a sports hospitality operator purchased in December, and now Bucket Listers for brand activation. The combined entities generated an estimated $180 million in revenue across 2025, though MARI has not filed consolidated financials. Emanuel is assembling the infrastructure to bid on integrated packages—venue, talent, production, and sponsorship fulfillment—that historically required multiple vendor relationships. Brands spending $5 million+ annually on live engagement now have a single counterparty option for Super Bowl, festival, and product-launch ecosystems.
This structure competes directly with Endeavor's own activation arm, but targets clients deterred by Endeavor's talent agency conflicts or those requiring faster decision cycles than a $13 billion entity permits. MARI operates without public shareholders and can underwrite risk on unproven event formats. Bucket Listers previously turned down acquisition interest from Omnicom and Stagwell in 2023, according to two people familiar with the processes, waiting for a buyer that would preserve creative autonomy while adding capital for venue pre-buys and talent guarantees.
Watch for MARI to announce a hospitality play tied to the 2026 FIFA World Cup, likely by March. Emanuel has been in conversations with hotel groups in Los Angeles and New York about exclusive room blocks and branded pavilions near match venues. Bucket Listers has already staffed preliminary site surveys in MetLife Stadium's surrounding area. Additionally, TPG's co-investment in MARI includes a right of first refusal on any add-on acquisitions, meaning further event-stack consolidation will likely route through the same capital base. Observers should track whether MARI pursues a ticketing platform or registration technology to close the consumer data gap that currently limits its retargeting capabilities.
Emanuel's bet is that brands will pay a premium to avoid coordinating five vendors when one entity can deliver the full activation, assume liability, and guarantee talent. The World Cup will test whether that thesis holds at $20 million+ package scale.
The takeaway
MARI's Bucket Listers buy completes a vertically integrated event stack outside Endeavor, targeting **$5M+** brand spenders who need single-vendor accountability.

Your next customer won't visit your website. Their AI will.
AI assistants have quietly taken over the first step of buying — they answer from catalogs they can read and shortlist whoever can actually ship. Two questions now decide whether you exist to that buyer: can a machine read your catalog, and can you fulfill the order. Most brands fail one or both and never find out why the orders went elsewhere. The winners of this shift aren't the loudest. They're the most readable. Build for the machine that's about to do the shopping.
