Weekly NFT market snapshot: sales up despite fewer active addresses

NFT marketplace dollar volume climbed to roughly $46.78 million over the seven days ending Sept. 12, reflecting a 6.8% increase from the prior week, according to CryptoSlam analytics. That rise in headline sales masks important structural shifts: the number of buyer and seller addresses plunged sharply while total transactions increased, driven in part by a small number of very large Bitcoin BRC-20 transfers.

Key weekly metrics

• Total NFT sales: $46.78 million (up 6.8%)
• Buyer addresses: 41,959 (down 84.67%)
• Seller addresses: 43,247 (down 85.13%)
• Transactions: 917,549 (up 48.75%)

These figures refer to on-chain addresses rather than confirmed, unique individuals. The contrast — far fewer active addresses but more transactions — indicates concentrated activity: many trades were likely executed by a smaller set of wallets or via programmatic activity, rather than broad retail participation.

Ethereum remains the largest chain by dollar volume

Ethereum led blockchain NFT sales with $16.83 million for the week, although that number fell 6.36% versus the previous period. Ethereum’s buyer-address count declined dramatically (down about 79.4% to 8,271). CryptoSlam also reported $794,730 in wash-trading volume on Ethereum; the platform displays wash volume separately and cautions that wash figures should not be summed with reported sales.

Bitcoin posts the largest weekly gain among top chains

Bitcoin’s NFT sales rose to $9.44 million, a 50.12% increase week-over-week. That gain was driven by several outsized BRC-20 NFT transactions: although buyer-address counts on Bitcoin also dropped (to 2,255, down about 82.8%), a handful of high-value transfers accounted for much of the chain’s weekly dollar volume. CryptoSlam listed $74,767 in wash volume for Bitcoin.

Polygon placed third by sales with $7.71 million (up 7.73%), recording around 13,888 buyer addresses — also down sharply. Notably, CryptoSlam separately showed $17.11 million in Polygon wash volume; because that figure exceeds the chain’s recorded sales, it highlights why wash-trading disclosures matter when interpreting chain-level numbers.

BNB Chain came in fourth with $4.02 million (up 25.99%), followed by Base at $2.48 million (down 35.34%) and Solana at $2.30 million (up 32.91%). Across the six leading networks shown on the dashboard, buyer-address counts declined substantially — including a roughly 90% fall on BNB Chain and an 86.97% drop on Base. Together those six networks made up about $42.78 million of the global $46.78 million total, with smaller chains supplying the remainder.

Top collections and what’s behind the numbers

Polygon-based Courtyard led collections for the week with $6.67 million in sales, posting 104,404 transactions and recording 16,253 buyer addresses and 14,268 seller addresses. Transactions increased nearly 10% while buyer addresses dipped 14.6% — a pattern consistent with many small, repeat transfers tied to a specific product model rather than broad single-owner purchases.

Courtyard tops weekly NFT collection sales

Courtyard’s NFTs represent ownership shares of physical collectibles held via its platform, according to Polygon’s project description. That model produces high transaction counts that are operationally distinct from the high-dollar Bitcoin BRC-20 transfers that dominated the week’s single-sale leaderboard.

Ethereum-based Argonauts climbed to second place with $4.36 million in sales, up 109.04%. The collection logged 2,331 transactions and 656 buyer addresses; transaction count and buyer participation actually trended down even as dollar volume jumped, suggesting larger average sale prices rather than broader buyer growth.

Bitcoin BRC-20 collections posted outsized moves

Bitcoin BRC-20 NFT collections made dramatic percentage gains, but often from a very small transaction base. The $X@AI BRC-20 collection reached $2.90 million (up 217.88%) through only nine transactions involving seven buyer addresses; its largest recorded sale was about $2.10 million, representing roughly 72% of the collection’s weekly volume. Another Bitcoin collection, $X@AGI BRC-20 NFTs, showed $1.72 million in sales across only three transactions. CryptoSlam’s platform classifies these transfers as NFT sales, but the dashboard alone cannot determine whether such concentrated trades reflect sustained demand across a broad community or a limited number of high-value transfers.

Other notable collections included CryptoPunks at $1.13 million (15 transactions, down 41.84%), BNB Chain’s OI NFT at $1.00 million (2,001 transactions), Guild of Guardians Heroes at $952,128 (down 2.27%), and Bitcoin-based $ATMC BRC-20 NFTs at $920,976 (up 80.47%).

Largest individual sales: Bitcoin BRC-20 dominated the top five

The five biggest individual sales reported by CryptoSlam during the week were all Bitcoin BRC-20 NFTs, underscoring how a few large transfers can significantly move chain-level dollar totals.

Top NFT collectible sales this week 

• 1: $X@AI BRC-20 — $2,095,886.72 (26.2326 BTC)

• 2: $X@AGI BRC-20 — $1,140,988.93 (14.3755 BTC)

• 3: $X@AGI BRC-20 — $574,078.04 (7.1817 BTC)

• 4: $X@AI BRC-20 — $401,684.92 (5.0818 BTC)

• 5: $X@AI BRC-20 — $395,775.82 (5 BTC)

Combined, those five trades totaled roughly $4.61 million — close to half of Bitcoin’s $9.44 million weekly NFT sales — highlighting that a concentrated set of high-value transactions, rather than broad-based retail activity, lifted Bitcoin’s weekly figures.

What this means for NFT market watchers and traders

• Interpret weekly sales totals with context: rising dollar volume can coexist with weakening participation if a few large trades dominate liquidity.
• Watch wash-trading disclosures: separate wash-volume figures on dashboards like CryptoSlam can materially change how you read chain and collection performance.
• BRC-20 and other token-format innovations on Bitcoin are increasingly shaping headlines and on-chain volumes; traders and collectors should track both the size and frequency of transactions to assess genuine market demand.

For investors, NFT creators, and traders focused on blockchain trends, this week’s data is a reminder that on-chain metrics require careful parsing. A healthy NFT ecosystem depends on both steady retail engagement and institutional or high-net-worth participation; when one group drives most dollar volume, that concentration can create misleading impressions about market breadth.

Bottom line

NFT sales ticked up to $46.78 million for the reporting week, with Ethereum still leading by total sales but Bitcoin posting the largest weekly gain thanks to a handful of multi-million dollar BRC-20 trades. Analyst attention should remain on address-level activity, wash-trading disclosures, and the distribution of transaction sizes to better understand whether dollar-volume shifts reflect broad market recovery or concentrated, atypical transfers.
