Royal Sybaris Launches Off-Market Observatory to Measure High-End Sales

Royal Sybaris, an international network of luxury professionals, has launched the Off-Market Observatory, a quarterly barometer designed to measure and report on high-end real estate transactions that occur outside the public market. The initiative aims to provide real figures on the Off-Market phenomenon, which has been estimated to account for up to 60% of high-end sales in France, according to Sea View Property (2023).

The Off-Market Observatory will publish four key indicators every quarter, covering prestige real estate, yachts, private jets, watches and jewellery, collector cars, fine art, wealth and capital. These indicators include the profile of sellers, the time to sell, the price gap between asking and achieved prices, and the Off-Market share of reported prestige transactions. The first edition will focus on prestige real estate, with other sectors joining as they accumulate enough contributors.

Albert Satre, the founder of Royal Sybaris, stated that the Observatory will bring together what luxury professionals observe, providing sellers and the press with reliable figures. The Observatory will operate under strict rules to ensure the accuracy and confidentiality of the data. Each edition will state the number of contributors, the countries covered, and the limits of the measurement. Figures will be published only if they rest on at least 10 contributors and 30 reported transactions, with no single contributor accounting for more than 30% of the segment's transactions. Contributors will answer in ranges, taking about 15 to 20 minutes per quarter, and will never share client names, property addresses, or transaction amounts.

Applications for the first edition of the Off-Market Observatory are open until January 21, 2027, at royalsybaris.com/en/observatory-off-market/contributors. Successful contributors will receive the Expert Contributor 2027 badge, admission to the Circle of Royal Sybaris, introductions to the press, a citation in each edition and press releases, and early access to the results for their sector and country.

Royal Sybaris, founded in 2014 by Albert Satre, who has worked in real estate since 2004, aims to provide a transparent and reliable measurement of the Off-Market phenomenon. The company's signature is "What matters is never on display," reflecting its commitment to keeping exceptional properties off the public market until they find the right buyer.
