The latest milestone in Caitlin Clark's trading card market arrived Saturday night when her most important insert sold for $341,600 in the 2025 Summer Goldin 100 auction.
Saturday's result is the fourth highest sale for a Clark card of any kind at public auction, according to data tool Card Ladder's public records, and the top sale recorded for a Kaboom of any kind. The previous record for a Kaboom was the $225,000 paid for a 2018 LeBron James Gold Kaboom /10 BGS 9.5 in a private sale in 2024.
Considered among the most important insert sets of the ultra-modern era, Kaboom cards feature comic book-inspired art and carry a significant premium on the secondary market. First created as a chase for Panini America’s 2013-14 Innovation Basketball, Kaboom has since grown to become one of the most coveted cards for each of its subjects.
Originally designed with a basic silver background, Panini has since added Gold parallels numbered to 10 and the Green 1/1. To date, the most expensive sale for any Clark insert, according to data tool Card Ladder’s public records, is the $80,000 paid in a private sale for a Gold parallel in July.
Clark's example to sell at Goldin represents just the second Green Kaboom to achieve a BGS Pristine 10 grade. In total, Beckett has graded 93 Green Kabooms across all players and sports.

The latest ultra high-end Clark card to hit the auction block, the Green Kaboom closely followed the sale of Clark’s Immaculate Logowoman 1/1, which sold at Goldin for $317,200 on Saturday.
To date, the most expensive sale for any Clark card is the $660,000 paid for the Flawless Logowoman 1/1 in July, the top card sale ever for a female athlete.
Saturday's sale of Clark's Green Kaboom also follows the record sale of the digital example on Panini Blockchain, which fetched $175,000 on Sept. 8. That result, which helped deliver a record month for the platform, is the most paid for any NFT on Panini Blockchain.
