The Big Number
$1 M.
That’s roughly what it can cost just to retrofit a single Biennale venue with basic infrastructure like electricity and air conditioning, before a single artwork goes on view. In Venice, many spaces aren’t built for exhibitions, so organizers are effectively turn historic buildings into temporary museums on tight timelines. Add in rent, and the price can hit $30,000 to $50,000 a month when also accounting for complex shipping routes, security, and installation. Staging a show in the city is less about hanging art and more about building a working system from scratch.

According to the Art Newspaper, the Venice Biennale has stopped pretending it isn’t a marketplace. This year, Christie’s is hosting an invitation-only selling show at Palazzo Ca’ Dario with works by Lucas Cranach the Elder, Andy Warhol, Louise Bourgeois, and others priced from $500,000 to $50 million, while other exhibitions across the city are also quietly or openly for sale. The article makes clear that this isn’t a sudden shift so much as a change in tone. Dealers and collectors have been underwriting Biennale shows for years, covering production, shipping, and staffing, but now they are more willing to say the obvious out loud: they need to sell for this whole enterprise to work. Add in Italy’s new 5 percent VAT on art imports and the fact that many of the works are newly made and priced on the primary market, and Venice starts to look less like a staging ground for future deals and more like a place where the deals actually happen. —Daniel Cassady, Art Business Reporter
