Prime property: what America's market surge reveals about Paris

In its 21 June 2026 issue, the French magazine Challenges examines the surge at the top of the American property market. Alexander Kraft, CEO of Sotheby’s International Realty France & Monaco, sums up the shift in a single line: “In Florida, house prices have tripled.” Homes that changed hands at 3 to 5 million dollars now sell for 10 to 20 million.

The movement points to something larger than Florida. It reveals how the world’s wealthiest are reshaping their holdings, and the distinct place Paris holds in that map of capital.

The top of the American market has shifted scale

The rise is sharpest at the very summit. “The price of hyper prime property has quite simply exploded,” notes Alexander Kraft. The segment between 50 and 200 million dollars now records landmark sales, where only a handful of such transactions took place each year not long ago.

Florida, America’s new luxury champion

Florida has become the leading luxury market in the United States. Fortunes built on artificial intelligence, cryptocurrencies and major funds are leaving New York and California for Miami and Texas. This shift of capital sustains strong demand for the rarest addresses, those whose position cannot be reproduced.

Tax, security, lifestyle: the drivers of the migration

Three reasons recur: tax, security and lifestyle. On the ultra-private island of Indian Creek, known as the “Billionaire Bunker”, a home still under construction sold for 170 million dollars. An outright record for Miami-Dade County. The island captures what the highest patrimonies seek: privacy, protection and an address nothing can replace.

What this market reveals

Beyond the figures, a pattern emerges. Capital looks for scarcity, security and value that endures across cycles. That logic does not stop at Florida. It runs through the great capitals of heritage, where the address matters more than the floor area, and where market depth reassures over the long term.

Paris, a patrimonial anchor

Within this global reshuffle, Paris holds a place of its own. The stability of its market, the depth of its heritage and the scarcity of its addresses make it a reference for an international clientele.

“Paris holds a place of its own. What is unfolding in Florida reflects a global trend: the world’s wealthiest are rebuilding their holdings around security, taxation and scarcity. The patrimonial depth and stability of Paris make it a sought-after anchor internationally.”

FAQ – Prime property, the American market and the position of Paris

Why have luxury property prices surged in Florida?

According to Challenges (21 June 2026) and Alexander Kraft, CEO of Sotheby’s International Realty France & Monaco, house prices in Florida have tripled. Homes sold at 3 to 5 million dollars now trade at 10 to 20 million. The rise follows the arrival of major fortunes from New York and California.

Why are the wealthy leaving New York and California?

The migration rests on tax, security and lifestyle. Florida levies no state income tax, which draws fortunes built on artificial intelligence, cryptocurrencies and major funds. Miami and Texas capture a growing share of these departures.

What is Indian Creek, the “Billionaire Bunker”?

Indian Creek is an ultra-private island in Biscayne Bay, Miami. In 2026, a home still under construction sold there for 170 million dollars, an outright record for Miami-Dade County. The island captures what the highest patrimonies seek: privacy, security and absolute scarcity.

What do international ultra-high-net-worth buyers look for?

They look for scarcity and value that endures across cycles: confidential addresses, off-market homes, properties whose position cannot be reproduced. In Paris, that logic appears in private mansions, high floors without facing views, family reception apartments and homes with a garden or a terrace.

Why does Paris remain a patrimonial anchor?

Paris remains an anchor thanks to the depth and stability of its market. As Paulo Fernandes, co-owner of Paris Ouest Sotheby’s International Realty, points out, what is unfolding in Florida reflects a global trend. The wealthiest rebuild their holdings around security, taxation and scarcity, and Paris offers that permanence.
