The NFT industry is rife with innovation. New use cases pop up every day,
stretching our imagination of what we can do with NFTs. Nevertheless,
properly categorizing the industry is difficult as there are many different
interpretations.

Based on this approach, we can broadly categorize the industry into eight
segments:
1. Art
2. Music
3. Collectibles
4. Games
5. Sports
6. Metaverse
7. Utility
8. Financial

With a total sales volume of over $8 billion, Ethereum far outstrips other
chains. The next largest is Ronin, Axie Infinity’s sidechain. However, we are
starting to see more and more NFTs being minted and sold on other
blockchains such as Binance Smart Chain, Polygon, and Solana.
Nevertheless, it is worth noting that the numbers above are just an estimate
as some chains like Tezos are not tracked on CryptoSlam, which means the
entire NFT industry may be a lot bigger than it appears. Moreover, both
Utility and Financial NFTs are not tracked by CryptoSlam either—this could
be because they are less popular as speculative investments and represent a
smaller portion of the entire NFT market.
