Walk into The Cosmopolitan of Las Vegas, and you’ll notice it’s got a vibe that’s just different. It’s got those purple-hued crystals at the Chandelier Bar, the "Secret Pizza" spot that everyone knows about but still feels like a win to find, and those wraparound balconies that let you see the Bellagio fountains without leaving your room. But if you’re standing there wondering who owns the Cosmopolitan Vegas, the answer is actually a lot more "corporate complicated" than a single name on a deed.
Gone are the days when a single billionaire like Steve Wynn or Sheldon Adelson just owned a whole building and the dirt beneath it. Today, the Strip is a giant game of Monopoly played with real-world billions.
The Split: Operations vs. Real Estate
Basically, the "Cosmo" (as everyone calls it) is split into two parts. Think of it like a house where one person owns the physical walls and the yard, but a completely different person runs the kitchen, cleans the rooms, and collects the rent.

In May 2022, a massive deal changed the face of the resort forever. MGM Resorts International paid about $1.625 billion to buy the right to run the place. They own the brand, the software, the database of guests, and they hire all the "CoStars" (the employees).
But MGM doesn’t actually own the land or the towers.
The physical real estate—the actual concrete and steel at 3708 Las Vegas Blvd S—is owned by a group of heavy-hitters. This landlord group includes:
- Stonepeak Partners (an investment firm)
- The Cherng Family Trust (the founders of Panda Express—yes, the orange chicken empire!)
- Blackstone Real Estate Income Trust (BREIT)
MGM pays this group roughly $200 million a year in rent just to keep the doors open. It’s a 30-year lease, so MGM is going to be the face of the Cosmopolitan for a long, long time.
Why Blackstone Sold (and How They Made a Killing)
Before the 2022 shakeup, Blackstone owned everything. They bought the resort from Deutsche Bank back in 2014 for about $1.73 billion. At the time, the Cosmo was kind of a mess. It was losing money, the rooms were starting to look a bit tired, and it didn't really have its footing yet.
Blackstone poured over $500 million into upgrades. They finished the top-floor suites that were just sitting empty, revamped the restaurants, and leaned hard into that "luxury-cool" branding.
When they sold it in 2022 for a total valuation of $5.65 billion, it became their most profitable single-asset sale ever. They basically tripled their money in less than a decade. Honestly, it’s one of the most successful turnaround stories in Vegas history.
What This Means for You (The Guest)
If you're a regular, the biggest change hasn't been the decor—it’s the points.
For years, the Cosmopolitan was this independent outlier. Now that MGM is at the helm, the resort has been fully integrated into the MGM Collection. This was a big deal for people who spent years building up status in the old "Identity" rewards program.
As of 2024 and 2025, the transition to MGM Rewards became the standard. You can now use your MGM points from the Bellagio or ARIA to grab a drink at the Cosmo.
Interestingly, despite being an MGM-run joint, the hotel is still part of the Marriott Autograph Collection. This is a rare "double-dip" situation where you can often use Marriott Bonvoy points for your stay while still being in the MGM ecosystem. It’s one of the reasons the property stays so busy—it has access to two of the biggest loyalty databases in the world.
The Future of the Cosmo Under MGM
Under the leadership of Sean Lanni (the President and COO who oversees the Cosmo along with ARIA and Vdara), the property is shifting slightly but trying to keep its "edge."

Vegas locals were worried MGM would "corporate-ify" the place and make it feel like every other hotel on the Strip. So far, that hasn't really happened. They’ve kept the high-energy dining scene, recently announcing new concepts like "The Corner Store" from Catch Hospitality Group, set to open in late 2026.
They know why people go there. It's the art, the weirdness, and the fact that it doesn't feel like a standard casino.
Actionable Takeaways for Your Next Visit:
- Check Your Rewards: If you have an old Identity card in a drawer, make sure you've officially linked it to your MGM Rewards account. Don't leave points on the table.
- Book Through Marriott: If you are chasing Marriott Titanium or Ambassador status, booking the Cosmo through the Marriott app is often the best "bang for your buck" on the Strip for earning Elite Night Credits.
- Watch the Lease: Since the "landlords" (Stonepeak/Cherng/BREIT) are separate from MGM, keep an eye on major renovations. Usually, the operator (MGM) handles the day-to-day, but massive structural changes involve the owners.
- Dining Reservations: The Cosmo's restaurants (STK, Zuma, Momofuku) remain some of the hardest tables to get. Use the MGM Rewards concierge if you're a Gold member or higher; they have more pull now than they did a few years ago.
The ownership of the Cosmopolitan is a perfect snapshot of how modern Las Vegas works. It’s no longer about a guy with a vision and a gold vest—it’s about private equity, real estate investment trusts, and massive hospitality corporations working together to make sure that $200 million rent check clears every year.
