What is the most expensive NFT?

Non-Fungible Tokens (NFTs) market is a recent development and it's still evolving. The most expensive NFTs have been sold for millions of dollars.

In March 2021, an NFT digital artwork "Everydays: The First 5000 Days" by the artist Beeple was sold at Christie's auction for $69.3 million, setting a record for the most expensive NFT ever sold. The artwork is a collection of digital images created by the artist over a period of 13 years.

In March 2022, another digital artwork named "The First 5000 Days" by the artist Mike Winkelmann, commonly known as Beeple, was sold for $69,346,250 in a Christie's auction. It became the most expensive digital artwork ever sold, and the third most expensive work by a living artist.

Additionally, there are other NFTs which were also considered as some of the most expensive NFTs ever sold such as "Everydays: The First 5000 Days" by Beeple ($69.3 million) and "The Forever Rose" by Mad Dog Jones ($69.3 million)

It's worth noting that the NFT market is highly speculative and is still in its early stages. The value of NFTs can be highly volatile and can fluctuate greatly over time, and the prices paid for some of the most expensive NFTs are still considered high even though they have set records.
