The Caitlin Clark Green Kaboom 1/1 NFT sold for $175,000 on Monday to set a record for the most expensive NFT on the Panini Blockchain platform.
Among the most important chases from the 2024 Panini NFT WNBA Rookie Royalty release, the card was pulled from a pack Sunday and sold within 24 hours for its full asking price.
The previous record for any card on Panini Blockchain was the $146,431 paid for the 2024 National Treasures Victor Wembanyama 1/1 Logoman last December. Prior to Monday, the most paid for a Clark card on the platform was the $51,248 paid for a Prizm Gold Vinyl 1/1 in February.
A Clark Gold Kaboom, numbered to 10, from the same set sold for $60,000 within 40 minutes of the Green Kaboom’s sale.
According to buyer Dingyu, a Berlin-based supercollector known by username “Spinotron,” the purchase was driven by Kaboom’s status as an important insert across the hobby.
“I feel like Kaboom is Panini’s best innovation and is universally embraced in the physical hobby,” Dingyu told cllct. “This card is captured really well and even rendered better in blockchain/animated format.”
“Also I trust those centibillionaires investing in WNBA teams, and I’m just doing parallel investment at the hobby level,” Dingyu added.

Monday’s result is a major moment for Panini Blockchain, which experienced its most successful month to date with $7 million in total transactions in August. Including Monday’s sale, more than $4.4 million has already been spent on the platform so far in September.
The recent surge has been heavily driven by the release of WNBA Rookie Royalty and ultra high-end collectors adding some of the most coveted NFTs on the platform.
Packs of WNBA Rookie Royalty, which feature just two NFTs, sold via Dutch Auction on Sept. 5 with a ceiling of $15,000 and floor of $500. Inventory eventually sold out around $1,100 but packs have since sold for an average of $2,751 and as much as $4,211.

Rookie Royalty’s digital release has similarly mirrored the success of the physical drop in July.
The physical set, which also featured just two cards, sold directly from Panini via Dutch Auction with a ceiling of $30,000 and a floor of $3,000. Rookie Royalty sold out close to the $3,000 floor, though boxes have since flipped for as much as $14,250 on eBay.
To date, the Rookie Royalty brand has produced three of the top five highest sales for women’s basketball NFTs on Panini Blockchain and three of the top four physical Clark cards of all time.
Packed with ultra high-end Rookie Patch Autographs and inserts, the physical Rookie Royalty release produced the Clark Flawless Logowoman 1/1, which sold for $660,000 in July to become the most valuable woman’s sports card of all time.
According to data tool Card Ladder, Clark has now had two public sales of $500,000 or more for physical cards and 13 of $100,000 or more. Including physical cards, Clark’s Green Kaboom NFT is the 10th-most expensive sale of a Clark card on the secondary market.
Led by Clark’s Green Kaboom, Monday has become one of the most successful single days for Panini Blockchain, with more than $1.265 million spent and nine sales of $10,000 or more by 4 p.m. ET.
Considered arguably Clark’s most important insert to date, the physical Green Kaboom will sell as part of the 2025 Summer Goldin 100 later this month. As of Monday afternoon, that card had reached $183,000, including buyer’s premium, on 16 bids.
When asked if he planned to pair the digital and physical Kabooms together, Dingyu had a simple answer.
“Tempting but probably not.”
