OpenSea

OpenSea is an American non-fungible token (NFT) marketplace headquartered in New York City. The company was founded by Devin Finzer and Alex Atallah in 2017.

OpenSea offers a marketplace online allowing for non-fungible tokens to be sold directly at a fixed price, or through an auction.

In 2021, following a heightened interest in non-fungible tokens, the company's revenue reached $95 million in February and $2.75 billion in September of that year. By January 2022, the company had been valued at $13.3 billion and was described as the largest non-fungible token marketplace. The daily trading volume on the OpenSea marketplace reached a record $2.7 billion on May 1, 2022, but four months later had dropped by 99%.
