Grayscale has announced that Cardano (ADA) now holds an 18.55% allocation in its Smart Contract Fund, following the firm's Q4 2025 portfolio rebalancing. This positions Cardano as the third-largest asset in the fund, trailing only Solana and Ethereum, which have allocations of 29.55% and 29%, respectively. The rebalancing reflects routine adjustments based on the CoinDesk Smart Contract Platform Select Capped Index. Cardano's significant allocation underscores its growing reputation in the smart contract ecosystem, despite launching its smart contract functionality in 2021. The cryptocurrency's inclusion in the Grayscale Smart Contract Fund since March 2022 highlights sustained confidence in its infrastructure. Cardano is also part of other Grayscale products, including the Digital Large Cap ETF, as the firm explores launching a spot ETF for ADA.
