Deadstock, a blockchain platform from ATH Labs, is testing a model that lets users trade ownership of physical Pokémon cards onchain while the cards remain in vaults, targeting a trading card market estimated at roughly $10 billion to $15 billion. The platform is being tested on Arbitrum and stores PSA 10 Pokémon cards in custody while issuing one-to-one tokens tied to each card, allowing ownership to change hands without moving the physical asset. The approach is designed to reduce frictions around shipping, authentication and marketplace fees in a sector where demand has become large enough to create retail queues and purchase limits at chains such as Target and Walmart. The main challenge remains whether tokenized platforms can build enough liquidity and reliable price discovery to compete with established marketplaces. eBay remains the dominant venue in the sector, with $2.62 billion in individual trading card sales in 2025, according to GemRate data. CoinDesk reported that House of Chimera found a significant share of volume on tokenized card platforms comes from game-like pack openings or instant-buy features rather than peer-to-peer trading between collectors, underscoring questions about how much organic secondary-market activity these models can generate. Deadstock's supply strategy still rests on access to Japanese inventory through Japan Trading Card Center, while broader investor interest in rare cards has been highlighted by Logan Paul's $16.5 million sale of a Pikachu Illustrator card.
