It will likely take several months to develop a functional and efficient NFT marketplace. A few key features will need to be included to make the marketplace viable, such as easy-to-use user interfaces, reliable and secure payment processors, and fraud prevention measures.
Additionally, there needs to be a solid infrastructure in place for exchanging NFTs. This includes an adequate number of buyers and sellers and a transparent and efficient rating system. A well-functioning NFT marketplace could take up to six months to create.
