American technology entrepreneurs, AI executives and private equity professionals are driving a new wave of demand for London’s super-prime housing market, with Mayfair emerging as the capital’s “Silicon Square” for wealthy US buyers.
New research from Beauchamp Estates has found there has been a 10% increase in wealthy American buyers purchasing luxury homes in London since the start of 2026.
Americans now account for 30% of all £5 million-plus sales across Prime Central London, up from 20% at the end of last year.
The agency says Mayfair has become the focal point of this demand, with American buyers responsible for half of all £5 million-plus transactions in the district. Purchasers from the Gulf account for a further 25%, meaning overseas buyers now dominate the area’s super-prime residential market.
SILICON SQUARE
According to Beauchamp Estates, Mayfair’s growing concentration of AI, fintech and private equity firms has transformed the district into one of Europe’s leading business hubs for US entrepreneurs.
The area is now home to more than 165 fintech businesses and around 200 private equity firms, many with American ownership or investment.

The renewed demand has helped lift activity across the market. Between January and May this year, Mayfair recorded £189.3 million of residential sales across 32 transactions, compared with £140 million from 28 deals during the same period in 2025.
The agency says many American buyers are relocating from California or establishing European bases to better connect with clients across Europe, the Middle East and Asia. Others are moving from the Gulf amid continuing geopolitical uncertainty, choosing London as a stable base while maintaining business interests overseas.
TURNKEY APARTMENTS
Typical purchasers are aged between their mid-30s and mid-50s and are seeking turnkey apartments priced between £5 million and £15 million.

Demand is strongest for newly refurbished or newly built lateral apartments offering modern layouts behind traditional Georgian or Victorian façades, with buyers favouring large open-plan kitchens, generous principal suites, walk-in wardrobes and air conditioning.
Beauchamp Estates has completed four sales worth more than £25 million to American buyers in Mayfair since April alone, including homes purchased by AI executives, hedge fund managers and private equity professionals establishing London residences.
LUCURY HOMES MARKET
Jeremy Gee, Managing Director of Beauchamp Estates, says: “Since the start of 2026 American and Gulf buyers have dominated the luxury homes market in Central London, accounting for 50% of sales across PCL and 75% in Mayfair, the capital’s poshest address.
“All the biggest deals over the last six months have been to either wealthy American or Gulf families.
“The booming American economy and the Gulf crisis has benefited the London real estate market which is viewed as providing value-for-money, an opportunity to acquire bargains and purchase outstanding trophy homes.”
BEST-IN-CLASS
And Vlad Viaryshka, Senior Super-Prime Sales Negotiator at Beauchamp Estates, adds: “Over the last six months London is back in the investment conversation with wealthy Gulf families and deals are being done whilst young American families have been choosing London, especially Mayfair, as a European base for their AI/tech or private equity firms.
“All the buyers are wanting turn-key homes, either newly built or recently refurbished.
“In order to sell vendors and developers need to ensure that they are presenting elegantly dressed homes with new or refreshed interiors and a modern specification.
“There is currently little buyer demand for second or third tier quality homes, purchasers are seeking best-in-class properties dressed and presented to the highest standard.”
