Russian billionaire Sergei Polonsky’s Mirax backs £20 million art sale at London’s “House of the Nobleman” exhibition

Russian billionaire Sergei Polonsky’s Mirax backs £20 million art sale at London’s “House of the Nobleman” exhibition The collection of press clippings reveals that a Russian real‑estate mogul (Sergei Polonsky) and his Mirax group financially backed a high‑profile art exhibition held in a luxury London property that was simultaneously being marketed for sale. The show featured £20 million worth of artworks, including four Picassos valued at over £6 million, and was positioned as a hybrid commercial event to attract wealthy collectors and potential property buyers. This suggests a possible conduit for moving large sums of money through art sales and real‑estate transactions, a pattern often scrutinised for money‑laundering or sanctions‑evasion risks. While no illegal activity is alleged, the nexus of Russian capital, high‑value art, and UK property warrants further investigative follow‑up. Key insights: Mirax, owned by Russian billionaire Sergei Polonsky, provided sponsorship and holds a minority stake in the Cornwall Terrace development.; The exhibition sold approximately £20 million of artworks (≈⅓ of the show), including rare Picassos and a Cézanne.; The venue (Boswell House, 2 Cornwall Terrace) was itself on the market for £29‑60 million, linking art sales to property promotion.
