The year 2021 has drawn to a close, and looking back at the crypto market's development, NFTs undoubtedly stand out as one of the most significant topics. If 2020 was the year of DeFi, then 2021 can rightly be called the year of the NFT explosion.
From art and collectibles to profile pictures, music, social interactions, games, and the metaverse, NFTs have undergone rapid evolution and diversification this year. The phrase “everything can be an NFT” seems to ring true as NFTs demonstrate their ability to intersect with almost any domain. As unique digital tokens based on blockchain technology, NFTs are verifiable, scarce, indivisible, and traceable. These properties have fueled massive interest and paved the way for practical applications. Throughout the year, numerous celebrities, influencers, brands, and corporations launched their own NFT projects, contributing to NFTs breaking into the mainstream.
What were the major trends that defined the NFT space in 2021? And what might the future hold?
Major Trends That Shaped the NFT Market in 2021
Trend 1: Rapid Growth and Mainstream Breakthrough
The evolution of NFTs can be divided into several phases. The period from 2015 to 2016 marked the infancy stage, symbolized by the creation of CryptoPunks. The following four years (2017–2020) were a phase of steady development, boosted by the launch of CryptoKitties. Then came 2021—the year of explosive growth. NFTs rapidly expanded beyond niche communities into the public consciousness, exciting investors worldwide about their future potential.
By December 27, 2021, the total market capitalization of NFTs reached $10.349 billion, a massive increase from the $61.74 million recorded at the beginning of the year. Growth accelerated especially from July onward. The number of NFT holders climbed to 1.356 million, seven times higher than at the start of the year. Among these, there were 826 “whale” addresses holding NFTs valued at over $1 million each.
Throughout the year, the NFT market peaked in trading volume during late August, late September, and early December. Although activity dipped slightly in the last two weeks of the year, the 7-day trading volume still stood at $240 million. The highest average daily sale prices were recorded on February 26 and October 29. As of December 27, the total secondary market trading volume for NFTs reached $17.176 billion, with 8.74 million trading accounts participating.
The number of NFT projects also saw substantial growth. According to nonfungible data, there were over 230 active NFT projects by year-end—a 65% increase from the first quarter. These projects span collectibles, metaverse, art, gaming, marketplaces, and more, with collectibles accounting for roughly 50% of the total.
Several key events propelled NFTs into the mainstream this year:
- On March 11, digital artist Beeple’s artwork Everydays: The First 5000 Days sold for $69.34 million at Christie’s, setting a new record for digital art and igniting the NFT market.
- The same day, CryptoPunks #3100 was sold for 4,200 ETH, a record-breaking price for an NFT profile picture.
- On March 22, an NFT representing Twitter founder Jack Dorsey’s first tweet sold for nearly $3 million.
- In May, a set of nine CryptoPunks sold for $16.9625 million at Christie’s.
- In July, the game Axie Infinity surpassed Honor of Kings in daily active users, driving a tenfold surge in NFT transactions.
Trend 2: Expansion of Use Cases and Ecosystems
As NFTs gained popularity, their applications expanded far beyond early digital collectibles. New use cases emerged in gaming, virtual real estate, music, metaverse, and more. At the same time, growing interest from luxury brands, financial institutions, tech firms, and media companies led to increased investment and development in the NFT space.
Initially, NFTs were primarily used in the digital art world, where they served as symbols of status and community membership. After Beeple and other artists brought NFTs to a mainstream audience, the technology evolved rapidly. Today, major categories of NFTs include:
- Profile pictures
- Collectibles
- Art
- Gaming items
- Virtual land
- Utility tokens
- Social tokens
- Music
- IP licensing
- DeFi integrations
Profile pictures and collectibles continue to dominate the market, accounting for 49.4% and 23.05% of the total market value, respectively. But 2021 also saw strong growth in gaming, metaverse, utility, and social tokens.
The expansion of NFT projects has also encouraged development across the entire ecosystem. Investment firm A&T Capital categorizes the NFT value chain into three layers:
- Infrastructure Layer: Includes base blockchains, sidechains/Layer 2, development tools, token standards, storage solutions, and wallets.
- Protocol Layer: Encompasses NFT minting protocols, primary markets, liquidity solutions, and DeFi-NFT integrations.
- Application Layer: Comprises vertical applications, secondary markets, and financial services built on the protocols.
This layered structure illustrates how mature and diversified the NFT ecosystem has become, with robust infrastructure supporting rapid innovation.
Trend 3: NFTs as Value Carriers in GameFi
Another major trend was the fusion of NFTs with blockchain gaming, often referred to as GameFi. The GameFi movement began gaining traction in March 2021 and exploded in July with the success of Axie Infinity. During this period, the number of blockchain games increased dramatically.
NFTs played a critical role in this growth. GameFi combines DeFi, gaming, and NFTs, leveraging the maturation of DeFi and NFT products. NFTs act as in-game assets and value carriers, enabling player-owned economies and stimulating market activity. This combination helped make GameFi one of the hottest sectors in crypto by the end of the year.
Conversely, the rise of GameFi further popularized NFTs. Features like true ownership, scarcity, and transferability make NFTs ideal for use in games and virtual worlds. In metaverse platforms like Decentraland and The Sandbox, each parcel of land is represented as an NFT, giving owners full control over their digital property. The popularity of these platforms drove up demand for virtual land, with some parcels selling for millions of dollars.
On November 23, Decentraland EST #4339 set a yearly record, selling for $2.4102 million. Other non-metaverse games like Loot, Axie Infinity, and Gods Unchained also dominated NFT gaming sales. The most expensive in-game NFT sold in 2021 was Million Dollar Rat, which fetched $1.713 million.
Despite this rapid growth, NFTGO data shows that gaming-related NFTs accounted for only 6.56% of the total NFT market capitalization by the end of the year, while art and collectibles made up 83%. This indicates that GameFi remains a领域 with significant room for expansion.
