NFTs Explained: What They Are, How They Work, and Are They Still Worth Anything?
NFTs had a wild rise and fall — but they are still here. Learn what non-fungible tokens are, how they work, and what they mean for digital ownership in 2026.
Non-fungible tokens — NFTs — dominated headlines in 2021 when a digital artwork by the artist Beeple sold at Christie’s auction house for $69 million. The hype that followed was extraordinary. JPEGs of cartoon apes sold for hundreds of thousands of pounds. Celebrities launched NFT collections. Brands from Coca-Cola to the BBC experimented with the technology.
Then the market crashed. By 2023, most NFT collections had lost more than 90% of their peak value. Headlines declared NFTs dead.
But the technology itself never disappeared. In 2026, NFTs are used for concert tickets, game items, property records, digital fashion, and membership clubs. The speculative frenzy is gone; the underlying utility remains.
This guide explains what NFTs actually are, how the technology works, and what role they play today.
What Does Non-Fungible Mean?
To understand NFTs, you first need to understand what “fungible” means. Something is fungible if any unit of it is interchangeable with any other unit.
A pound coin is fungible. If you lend someone a pound and they return a different pound coin, nothing has changed. Bitcoin is fungible: one BTC is worth exactly the same as any other BTC.
Non-fungible means unique. A painting by Rembrandt is non-fungible — there is only one, and a copy is not the same thing. A match-worn football shirt from a famous game is non-fungible. Your grandmother’s ring is non-fungible.
An NFT is a unique token on a blockchain that represents ownership of a specific item. Each NFT has a unique identifier that distinguishes it from every other token, even if the underlying file looks identical.
How NFTs Actually Work
An NFT is a smart contract on a blockchain — usually Ethereum, though Solana, Polygon, and other chains also support NFTs. The smart contract contains a token ID, the owner’s wallet address, and metadata pointing to the associated file.
It is important to understand what the NFT itself contains. Most NFTs do not store the image, video, or music on the blockchain — that would be prohibitively expensive. Instead, the NFT contains a link to the file, which is usually stored on a decentralised storage system like IPFS (InterPlanetary File System) or a regular web server.
This creates a risk that is often overlooked: if the hosting goes offline, the link breaks. The NFT still exists on the blockchain, but the file it points to may be inaccessible. This is why the survival of the hosting infrastructure matters for long-term NFT ownership.
When you buy an NFT, the blockchain records the transfer of ownership. This record is permanent and publicly verifiable. Anyone can see who currently owns any given NFT.
What NFTs Are Actually Used For in 2026
The speculative JPEGs market has largely deflated. But NFTs have found genuine utility in several areas.
Event tickets: NFT-based tickets cannot be counterfeited and transfer easily between resellers. The secondary market is transparent and royalties can be automatically paid to the original event organiser on each resale. Major concert promoters and sports clubs in the UK are piloting NFT ticketing systems.
Gaming: In-game items — weapons, skins, characters — are natural candidates for NFTs. Players can truly own their items and trade them on open markets. Games built on Immutable X and Polygon have hundreds of thousands of active players.
Digital art and collectibles: The market has stabilised at a much lower level than peak 2021. Serious digital art collectors and artists continue to use platforms like Foundation and SuperRare. The audience is smaller but more genuine.
Membership and access tokens: NFTs function as membership cards that grant access to exclusive communities, events, or content. Holders of certain NFTs get Discord access, early product launches, or in-person events. This is one of the more durable use cases.
Brand loyalty: Brands including Nike, Adidas, and several luxury fashion houses have used NFTs to create verified digital counterparts to physical products and reward loyal customers.
Real-world asset tokenisation: NFTs can represent real-world assets like property deeds or luxury watches. This is still early-stage in the UK, but pilot programmes exist.
Are NFTs Worth Buying in 2026?
This is a question only you can answer based on your own circumstances and risk tolerance. Here is an honest assessment.
The speculative NFT market is a highly illiquid, high-risk environment. Most NFT collections from 2021-2022 are worth very little today. Without understanding why a specific NFT would hold or increase in value, buying one is closer to gambling than investing.
However, NFTs with genuine utility are different. An NFT concert ticket has a clear use case. An NFT that grants lifetime access to a software product has measurable value. An NFT from an established artist with a proven collector base has more defensible value than an anonymous avatar project.
The question to ask before buying any NFT is: what is the actual utility or claim this token represents, and would anyone want this in six months?
NFTs and UK Tax
HMRC treats NFTs as cryptoassets. Buying and selling NFTs is subject to Capital Gains Tax. If you bought an NFT for £1,000 and sold it for £4,000, you owe CGT on the £3,000 gain — which counts towards your annual CGT allowance (£3,000 in the 2025/26 tax year).
Creating and selling NFTs as an artist may be treated as trading income and subject to Income Tax instead. HMRC has published specific guidance on NFT taxation that is worth reading if you are active in this market.
Keep records of every NFT purchase, sale, and associated gas fee. NFT tax calculation is genuinely complex due to gas fees, royalties, and cross-chain transfers.
What This Means for UK Readers
NFTs are not the get-rich-quick scheme they were marketed as in 2021. They are also not dead. They are a technology for proving digital ownership — and like most technologies, they are finding their way into practical applications over time.
If you are interested in NFTs, focus on utility over speculation. Understand exactly what you are buying and what claim it represents. And always factor in UK tax obligations before trading.
