- • Fund weightings are subject to change after the August 3 rebalance date as published allocations may fluctuate based on market conditions and index methodology.
Summary
Grayscale Investments completed its second quarter rebalancing of its Smart Contract Fund on August 3, 2026, introducing BNB as the portfolio's largest holding with a 30.6% allocation. The addition elevated BNB ahead of Ether and Solana, which maintained 29.47% and 29.15% weightings respectively. The rebalancing followed the CoinDesk Smart Contract Platform Select Capped Index methodology, establishing BNB's position immediately upon addition while maintaining Ether and Solana near their prior allocation levels from the fund's May 1 review.
The Q2 rebalancing resulted in significant portfolio restructuring, particularly affecting smaller-cap holdings. Cardano experienced the most substantial reduction, declining from 17.96% to 4.88% of the fund's composition. Hedera, Avalanche, and Sui all saw meaningful allocation cuts, falling to 2.08%, 1.92%, and 1.90% respectively. To accommodate BNB's entry, Grayscale proportionally sold existing fund components and deployed proceeds into the new position, a systematic approach consistent with index-tracking methodologies rather than active management decisions.
Beyond the Smart Contract Fund, Grayscale rebalanced additional thematic crypto products during the quarter. Uniswap maintained the largest position in the DeFi Fund at 34.16%, despite reduction of UNI exposure, while NEAR Protocol led the AI Fund at 31.35% following partial position trimming. The rebalancing underscores Grayscale's systematic quarterly adjustment framework, with fund weightings remaining subject to modification following the August 3 implementation date as market conditions and index calculations evolve.
