NFT Valuations

NFTs are already a multi-billion-dollar market, and having robust and accepted valuation tools in the NFT space is essential for artists, collectors, and investment managers. NFTs, however, are at a nascent stage. We believe they will grow to absorb a meaningful percentage of the art, collectible, gaming, and community markets and then extend to a whole array of non-fungible real-world goods and services. In other words, by the end of the decade, we believe NFTs will be a multi-trillion-dollar market. It is critical for this ecosystem for robust valuation methods to emerge, and we hope to play an essential role in this regard, particularly given the potential for composability between decentralized finance and NFTs.

NFT Valuations is a company with the mission to establish a robust and defensible methodology for calculating Non-fungible Tokens (NFTs) market capitalizations on an ecosystem basis. It is a startup company that started in April 2021, backed by the University of Nicosia (UNIC).
