Ask three research houses which city is the world's most expensive and you will get three different answers. That is not sloppiness. It is methodology.
Knight Frank measures how much prime space one million dollars buys. Henley and Partners with New World Wealth measure average price per square metre of prime residential stock. Savills tracks prime values across 30 metropolitan markets but excludes Monaco entirely, on the grounds that a principality is not a city. Each is internally consistent and each produces a different leaderboard.
This ranking uses the Henley average prime price per square metre as its spine, with Knight Frank's relative value data alongside as a cross check.

1. Monaco
Monaco is not the most expensive city in the world by a margin. It is the most expensive by a chasm.
At roughly $38,800 per square metre, prime Monaco costs about 41 per cent more than second placed New York. Knight Frank's relative value measure is starker still: one million dollars buys 16 square metres, down from 17 in 2020 and the tightest figure in the entire index. That is roughly 172 square feet, or a generous walk in wardrobe. Savills, using a different basket, puts average Monaco values above EUR 57,000 per square metre in 2026, with Larvotto higher again.
The drivers are structural and unlikely to change. The principality covers about two square kilometres. There is no meaningful development land, only reclamation. There is no personal income tax for residents, French nationals excepted. Over 40 per cent of residents are millionaires, the highest concentration on earth.
Who buys here: internationally mobile ultra high net worth individuals establishing tax residency, second home buyers in the Riviera ecosystem, and family offices seeking an EU adjacent base.
2. New York
New York clears roughly $27,500 per square metre in its prime segment, with the million dollar footprint at 34 square metres, marginally more generous than London.
That is worth sitting with. For twenty years the accepted wisdom was that London commanded a premium over Manhattan. In the 2026 data the two have reached rough parity, and the direction of travel is not in London's favour. Knight Frank noted New York prices rising marginally in 2025 despite tax threats, with inventory for high quality turnkey property running low.
Manhattan's true trophy corridor, Billionaires' Row and the blocks facing Central Park, trades far above the citywide prime average. Ken Griffin's $238 million purchase at 220 Central Park South priced at just under $10,000 per square foot, roughly $107,000 per square metre.
3. Hong Kong
Hong Kong sits third by absolute price at roughly $26,300 per square metre, but second on relative value at 23 square metres per million dollars. Savills, which excludes Monaco, ranks it first among its 30 tracked cities at approximately EUR 36,700 per square metre.
Three positions for the same city, in the same year, illustrate exactly why methodology matters. Hong Kong's ultra prime tier is a market of its own: The Peak produced the highest price per square foot ever recorded in Asia at HK$140,800, roughly $18,100, at Mount Nicholson in 2021. Knight Frank observed one of the strongest upticks in super prime sales anywhere at the close of 2025, suggesting the multi year correction in the broader market has not touched the top.
4. London
London prime runs around $24,000 per square metre, with a million dollars buying 33 square metres.
London is the most interesting entry here because it is the only top five market where the trajectory is defensive. Knight Frank's assessment is blunt: tax rules aimed at wealthy residents have pushed budgets lower and encouraged renting over buying. The firm describes London shifting toward a dip in, dip out model, a place the wealthy visit for business and culture rather than one where they establish permanent residence.
The consequences are visible in the stock. Appetite for vast square footage has been replaced by demand for well located boltholes, and the super prime rental market has surged as buyers avoid stamp duty exposure. Meanwhile Milan and Madrid are actively capturing capital that would once have defaulted to London.
5. Saint-Jean-Cap-Ferrat
At roughly $21,200 per square metre, this French Riviera peninsula outranks Paris, Miami and Los Angeles. It is not a city. It is a headland of villas between Nice and Monaco with a population under 2,000.
Its inclusion in a most expensive cities ranking is a methodological quirk worth flagging honestly, but it is genuinely instructive: in the global prime market, micro locations with absolute supply constraints and proximity to a tax advantaged jurisdiction now outprice most world capitals.
6 to 10: Paris, Palm Beach, Miami, Los Angeles and Geneva
The next tier clusters closely enough that ordering shifts year to year and by methodology.
Paris holds sixth, supported by tightly regulated supply in the 6th, 7th and 8th arrondissements and by the capture of London displaced capital.
Palm Beach has become a genuine ultra prime market rather than a seasonal one, driven by the post 2020 relocation of American financial wealth to Florida.
Miami appears eighth by absolute price but has seen the most aggressive contraction in relative value of any market tracked: one million dollars now buys 58 square metres, close to half of what it bought five years ago. Prices dipped slightly in 2025 after an extraordinary run since 2021.
Los Angeles is contending with Measure ULA, the transfer tax on high value property sales, which Knight Frank identifies as having cooled super prime liquidity meaningfully.
Geneva ranks third globally on relative value at 28 square metres per million dollars, ahead of both London and New York, even though its absolute price per square metre trails them. Swiss restrictions on foreign purchase keep the qualifying buyer pool small and the stock tightly held.
Where does Dubai sit?
Dubai does not appear in the top ten by absolute price per square metre, and any article claiming otherwise is not reading the data. It appears in almost every other league table that matters.
Knight Frank's Wealth Report 2026 records Dubai prime prices up roughly 25 per cent in 2025 and close to 200 per cent over five years, making the UAE the global leader in super prime residential performance. Dubai recorded 500 home sales above $10 million in 2025, worth more than $9 billion, a volume that places it alongside New York and London at the very top of the ultra prime transaction table despite a lower average price per square metre.
The distinction is simple, and it is the whole reason absolute price and growth rankings tell different stories:
- Absolute price rankings measure what a square metre costs today. Monaco wins because it ran out of land decades ago.
- Growth rankings measure the rate of change. Dubai wins because it is still absorbing an inflow of capital and population no mature market can replicate.
For a buyer, the practical translation is that Dubai currently offers roughly three to four times the prime floor area per dollar of Monaco or Hong Kong, in a zero income tax jurisdiction, with a ten year residency visa attached to a AED 2 million purchase. That combination does not exist anywhere in the top five. Abu Dhabi is emerging on the same axis as a lower profile alternative.
How to read prime property rankings
Check whether the figure is average or trophy. A citywide prime average and the price of the best building in that city can differ by a factor of five. Monaco averages $38,800 per square metre; Manhattan's record penthouse cleared roughly $107,000.
Check whether Monaco is in the sample. Savills excludes it. Henley and Knight Frank include it. That single decision moves Hong Kong between first and third.
Check the currency. Prime price changes are usually reported in local currency. Tokyo's headline 58.5 per cent surge was substantially a weak yen story, which made Japanese luxury new builds a value play for dollar denominated buyers.
Check the date. These indices publish annually with a lag. The 2026 report reflects 2025 performance.
Frequently asked questions
What is the most expensive city in the world to buy property?
Monaco, at approximately $38,800 per square metre, where one million dollars buys just 16 square metres of prime space.
Why do different reports name different cities as the most expensive?
Because they measure different things. Knight Frank measures space per dollar, Henley measures average price per square metre, and Savills tracks 30 cities while excluding Monaco. Each is valid within its own methodology.
How much does $1 million buy in Monaco?
Approximately 16 square metres, or about 172 square feet, the smallest footprint of any market in the index, down from 17 square metres in 2020.
Is Dubai one of the most expensive cities for luxury property?
Not by average price per square metre, where it sits outside the global top ten. Dubai leads on growth instead, with prime prices up roughly 25 per cent in 2025 and close to 200 per cent over five years.
Is London still one of the world's most expensive markets?
Yes, at roughly $24,000 per square metre, but its relative position has weakened as tax changes push budgets lower and shift demand toward renting and smaller footprints.
How much prime property does $1 million buy in Dubai compared with Monaco?
Roughly three to four times as much floor area, plus no income tax and a ten year residency visa attached to a AED 2 million purchase.
