Still haven't learned what NFTs are? Well, this one just sold for $69M

A digital artwork sold for nearly $70 million US at Christie's on Thursday, in the first sale by a major auction house of a piece of art that does not exist in physical form.

Everydays - The First 5000 Daysis a digital work by American artist Mike Winkelmann, known as Beeple. It is a collage of 5,000 individual images, which were made one-per-day over more than thirteen years.

The sale of the work for $69,346,250 put Beeple in the top three most valuable living artists, Christie's said in a tweet.

Beeple responded to the sale result with an expletive on Twitter.

The work is in the form of a new type of digital asset a non-fungible token (NFT) meaning it is authenticated by a digital ledger known as blockchain, which certifies its originality and ownership.

The tokens, which have swept the online collecting world recently, are used to prove that the item is one of a kind, allowing buyers to claim ownership.

NFTs are aimed at solving a problem central to digital collectibles: how to claim ownership of something that can be easily and endlessly duplicated.

Fallen Trump fetched $6.6M

The market for NFTs has soared in recent months as enthusiasts and investors use spare savings to buy up items that exist online. Last month, a 10-second video clip featuring an image of a fallen Donald Trump, also by Beeple, sold for $6.6 million on an NFT marketplace called Nifty Gateway.

"Without the NFTs, there just legitimately was no way to collect digital art," said Beeple, who makes irreverent digital art on themes such as technology, wealth and American politics.

Christie's said Beeple's collage fetched the highest price in an online-only auction and the highest price for any winning bid placed online.

Some 22 million people tuned in on the Christie's website for the final moments of bidding, with bidders from 11 countries taking part.

Between Grimes, Kings of Leon and even NBA Top Shot, all of a sudden it seems like NFTs are everywhere. But what are non-fungible tokens, really? And why are they blowing up right now? CBC Business reporter Pete Evans explains. Find the links we talk about in this episode here: cbc.ca/1.5943429

Asked what he thought of the multi-million dollar bids on his work, the 39-year-old graphic designer, who has created concert visuals for the likes of Justin Bieber, One Direction and Katy Perry, said he was lost for words.

"I don't know. ... Maybe you can put an emoji into the story," he said. "It's so crazy."

For NFTs, the artist's royalties are locked in to the contract: Beeple receives 10 per centeach time the NFT changes hands after the initial sale.

"I do really think that this is going to be seen as the next chapter of art history," Beeple said.

NFT frenzy

Various digital objects can be minted as NFTs and traded as assets, including art, sports collectibles, patches of land in virtual worlds, cryptocurrency wallet names and even tweets. Twitter Inc boss Jack Dorsey is conducting a digital auction of his first ever tweet, in NFT form.

Art NFTs make up around a quarter of the all-time NFT sales volume ($415 million) according to NonFungibles.com, which aggregates sales history data for the Ethereum blockchain, the most commonly used ledger for recording these types of assets.

Musicians are also getting in on the hype, with American rock band Kings of Leon having launched an album as an NFT.

Beeple says the explosion in NFTs is due in part to the increased amount of time people are spending online during the pandemic. Like many enthusiasts, he also believes they could represent the future of ownership.

"Equities have been the predominant asset class for the last hundred years, or whatever. I don't think it's guaranteed that that's always going to stay like that. I think kids today hate corporations," he said. "So the idea that they're just going to automatically blindly give them their money to invest, I don't know about that."

Risk of losses when hype dies down

But, like many new niche investment areas, there is a risk of losses if the hype dies down. Many NFTs will eventually become worthless, Beeplesaid.

Although NFTs can function as a legally enforceable contract, they also raise issues relating to insurance, tax and intellectual property, said Max Dilendorf, a cryptocurrency lawyer and partner at Dilendorf Law Firm in New York.

"If you are a buyer of an expensive piece of NFT, you have to know what features and terms you are subject to," he said.

"From my experience, participants in NFT markets are not really thinking it through carefully."

Dilendorf said that he expects the entire physical art market to be digitized in NFT form in the next five years.
