The Sotheby’s auction house has been named as a defendant in a lawsuit filed by investors who regret buying Bored Ape Yacht Club NFTs that sold for highly inflated prices during the NFT craze in 2021. A Sotheby’s auction duped investors by giving the Bored Ape NFTs “an air of legitimacy… to generate investors’ interest and hype around the Bored Ape brand,” the class-action lawsuit claims.

The boost to Bored Ape NFT prices provided by the auction “was rooted in deception,” said the lawsuit filed in US District Court for the Central District of California. It wasn’t revealed at the time of the auction that the buyer was the now-disgraced FTX, the lawsuit said.

“Sotheby’s representations that the undisclosed buyer was a ‘traditional’ collector had misleadingly created the impression that the market for BAYC NFTs had crossed over to a mainstream audience,” the lawsuit claimed. Lawsuit plaintiffs say that harmed investors bought the NFTs “with a reasonable expectation of profit from owning them.”

Sotheby’s sold a lot of 101 Bored Ape NFTs for $24.4 million at its “Ape In!” auction in September 2021, well above the pre-auction estimates of $12 million to $18 million. That’s an average price of over $241,000, but Bored Ape NFTs now sell for a floor price of about $50,000 worth of ether cryptocrurrency, according to CoinGecko data accessed today.

Investors previously sued Bored Ape creator Yuga Labs, four company executives, and various celebrity promoters including Paris Hilton, Gwyneth Paltrow, Kevin Hart, Snoop Dogg, Sere
