NFTs, Non-Fungible Tokens
Follow the Money
NFT sales fell 95% from their 2021 peak, but carbon credit and gaming NFTs show real utility
A non-fungible token, or NFT, is a unique digital certificate of ownership recorded on a blockchain. Unlike a cryptocurrency, no two NFTs are identical. In 2021, this idea sparked a genuine mania. By 2026, most of that mania has collapsed, though a smaller, more specific market survives underneath it.

What Happened: The Numbers
NFT sales peaked at roughly $17.7 billion in 2021. By 2025, annual volume had fallen to about $5.5 billion, down 37% from 2024 alone, and the total NFT market cap had shrunk from around $9 billion to roughly $1.4-2.4 billion, more than 90% below its 2022 peak.
The collapse hit infrastructure, not just prices. Nifty Gateway, one of the earliest major NFT platforms, shut down in February 2026. Foundation, a leading digital art marketplace, closed the same April after a failed rescue deal. Nike sold its RTFKT digital sneaker venture in January 2026, and Reddit wound down its Collectible Avatars programme, ending two of the clearest Web2-to-Web3 bridge stories the market had.
Supply and demand moved in opposite directions. NFT minting hit a record 1.3 billion tokens in 2025, up 25% year-over-year, even as unique buyers fell to roughly 216,000 by March 2026 and average art NFT sale prices dropped from $462 in 2021 to under $100.
What Survived: A K-Shaped Market
Analysts increasingly describe the current market as “K-shaped”: a small top tier capturing most remaining value, and a long tail of roughly 1,700 active projects where the overwhelming majority trade in the single digits or not at all.
Gaming NFTs are the clearest genuine growth story, with transaction counts up 140% year-over-year into 2026. Titles like Illuvium and Gods Unchained succeed because players want the in-game items for gameplay first, resale second, a sharp contrast to the collapsed “play-to-earn” model of Axie Infinity, which depended on an unsustainable token economy.
A handful of blue-chip collections, CryptoPunks, Bored Ape Yacht Club, and Azuki, retain floor prices above $10,000, sustained by brand recognition and licensing deals rather than speculative trading. Real-world asset tokenization has emerged as what one industry report calls “the surprise survivor”: institutional players are using NFT-style tokens as compliance-friendly ownership records for real estate, trade finance, and government bonds, with over 30% of institutional NFT deals in 2025 featuring fractional ownership or embedded yield.
NFTs, Blockchain, and the SDGs
Beyond speculation, blockchain’s verification properties have found a genuine, if modest, foothold in global development. The clearest example is carbon credit tokenization. Projects like Xange, a UN-backed climate fintech, are issuing NFTs representing verified carbon removal from Africa’s Great Green Wall Initiative across the Sahel, while CarbonLand Trust uses drone monitoring paired with NFTs to help forest owners access carbon markets more affordably.
The logic connects directly to SDG 13, climate action: each NFT maps a verified tonne of carbon reduction to an immutable on-chain record, referencing recognised standards like the Verified Carbon Standard and Gold Standard, making it harder to sell the same credit twice. Projects tied to the Great Green Wall also touch SDG 8, decent work, by directing revenue and jobs toward carbon removal activity in one of the world’s most climate-vulnerable regions.
This use case comes with real caveats worth stating plainly. An NFT only verifies what the underlying registry records; it cannot fix a low-quality carbon project. Voluntary carbon markets have faced well-documented over-crediting scandals in the past, and tokenization changes how a credit is tracked, not whether the emissions reduction it represents actually happened.
Other proposed development use cases, digital identity credentials for unbanked populations, land registries, professional credentials, remain far earlier stage and more speculative than the carbon credit example, with limited independent evidence of impact so far. RYB treats these as worth watching, not yet proven.
Looking Forward
The data does not support a return to 2021-style mania, and most analysts now treat that scenario as unlikely. The more probable path is a permanently smaller, K-shaped market: a thin layer of gaming assets, blue-chip collectibles, and tokenized real-world assets sitting above a long tail of effectively worthless collections.
Real-world asset tokenization looks like the most consequential trend to watch, echoing the same shift RYB covers on its Crypto page, where tokenized treasuries and institutional RWA products are growing faster than speculative trading. Carbon credit NFTs sit within this broader movement, and their growth will likely track the wider voluntary carbon market’s own credibility problems as much as blockchain adoption itself.
For global development specifically, the honest answer is narrow but real: NFTs are not a financial inclusion tool at meaningful scale yet, but verified, transparent carbon and environmental asset tracking is a genuine, growing use case worth continued attention.
