Ken Griffin Sells Worth Avenue Building to Blackstone for $86M

Published: August 20th, 2026

Blackstone is the buyer, chasing one of the country's priciest shopping streets. Griffin paid $83 million for the building just three years ago, and the flat exit lines up with his growing bet on Miami.

Key Takeaways

Ken Griffin sold his 125 Worth Avenue office-and-retail building to Blackstone for $86 million, just $3 million above the $83 million he paid in 2023.
After transaction costs, the sale is likely closer to a wash than a real profit, even for one of the world's richest people.
It looks like the flat exit lines up with Griffin's shift toward Miami, where he is building a $2.5 billion Citadel headquarters.

Ken Griffin does not usually move real estate without a plan, so a near break-even sale from one of the world's richest men is worth a second look. According to The Real Deal, the Citadel founder sold his three-story building at 125 Worth Avenue in Palm Beach to Blackstone for $86 million, only $3 million more than he paid in 2023. For a headline number that big on a street this famous, the profit is thin, which raises the real question: why sell just to break even?

What did Ken Griffin sell, and for how much?

The property is 125 Worth Avenue, a roughly 49,401-square-foot Class A office-and-retail building. It has three stories and sits on 0.79 acres with 165 covered parking spaces. It dates back to 1974, and once housed a Neiman Marcus flagship.

Griffin sold it to Blackstone for $86 million, all cash, which works out to about $1,720 per square foot. Ground-floor tenants include Truist Bank and the Ferretti Group yacht brokerage.

The buyer? Blackstone's real estate services arm, Revantage. Griffin had paid $83 million for the building in 2023.

The address is the whole appeal. As Larry Mastropieri put it on the Discover South Florida Podcast: "Worth Avenue in Palm Beach, on Palm Beach Island, is arguably one of the coolest, most sellable trophy real estate projects ever. Epic location. You're walking distance to the beach." Location, location, location. That is exactly what makes this building an easy sell, yet it was a near-flat return.

Why did a billionaire barely break even?

If you do the math, selling for $86 million against an $83 million purchase looks like a $3 million gain, but transaction costs on a deal this size, from commissions to fees, can eat up most or all of that. So the real return is probably close to zero, and possibly a small loss. For most people that would sting; for a man worth somewhere between $37 and $50 billion, it is a rounding error.

So why sell at a wash? To analysts and reporters, the flat price reads as a portfolio shift rather than a cash grab, and Griffin has not publicly explained the deal, so this is how it looks from the outside, not a stated reason.

What is clear is the pattern: he has been concentrating his recent real estate moves on Miami, where he just started building a 54-story, $2.5 billion Citadel headquarters in Brickell, and he already sold the neighboring 151 Worth Avenue for $80 million last year. As Larry read it: "It's a repositioning. They probably have a better strategy, or something they can do with that money that they believe is going to make them more money." That fits a broader Griffin bet on South Florida that runs in Miami.

Why is Blackstone buying on Worth Avenue?

For the buyer, this is a straightforward high-street retail play. Blackstone principal Elena Clarfield called Palm Beach "one of the highest performing luxury retail markets in North America," and the purchase fits Blackstone's global strategy of collecting trophy shopping streets, the same instinct behind its buys on London's New Bond Street, SoHo in New York, and Rue Saint-Honore in Paris.

Revantage, Blackstone's in-house real estate services platform, supports more than 12,700 assets with a combined value topping $500 billion.

The numbers on Worth Avenue explain the confidence. The street runs at under 1% retail vacancy with rents near $92 per square foot, among the highest anywhere, driven by extreme scarcity of space and a steady flood of high-income residents into one of Florida's richest towns. Where Griffin sees capital better spent elsewhere, Blackstone sees a scarce trophy it can hold for the long run. Win-win?

What does this say about the Palm Beach market?

Nothing about this sale looks distressed. Worth Avenue is in the middle of a trophy-retail buying spree, and this deal sits right in the pack. Earlier in 2026, the Reuben Brothers and Crown Onyx paid $200 million for the Esplanade at 150 Worth Avenue, and Acadia Realty Trust paid $43 million for 225 Worth Avenue.

Across Palm Beach County, commercial investment sales reached about $690 million in the first half of 2026, the second-busiest first half on record and the highest since 2022, according to Cushman and Wakefield.

Here's the takeaway for buyers and investors from all this. Palm Beach trophy real estate holds its value even when fast appreciation cools, because the money chasing it wants scarcity and prestige more than a quick return.

Barely, if at all. The $3 million paper gain over three years is likely erased by transaction costs like commissions and fees, so the deal is closer to break-even, and possibly a small loss. For someone worth tens of billions, the exact figure matters far less than the strategy behind it.

Who bought 125 Worth Avenue?

The buyer is Blackstone, one of the world's largest commercial real estate owners, acquiring the building through its in-house real estate services platform, Revantage.

Is Palm Beach real estate still a good investment?

This is general information rather than financial advice, but the market signals are strong. Worth Avenue has under 1% retail vacancy and record investment sales countywide. That said, trophy retail tends to prioritize scarcity and prestige over high yields, so returns can be modest even as values hold.
