The report found that, despite the pandemic, 92 percent of the surveyed collectors had bought a work of art in 2020. A majority had spent more than $100,000 on art during the last six months.

“Ninety-two percent seems a big number,” said Candace Worth, a New York-based adviser specializing in contemporary art. “But collectors have been buying online and have been taking appointments with galleries all summer. People are stuck at home, bored and itching to spend money on art,” Ms. Worth said.
