By Grayscale Investments has made BNB the largest holding in its Smart Contract Fund, overtaking both Ethereum and Solana following the firm’s second-quarter portfolio rebalance, a move that underscores growing institutional interest in the BNB Chain ecosystem. According to Grayscale’s latest portfolio update, BNB now represents 30.6% of the Smart Contract Fund, ahead of Ether at 29.47% and Solana at 29.15%. The asset manager funded the new allocation by proportionally reducing its existing holdings across the portfolio, marking the first time BNB has been included in the fund.
The rebalance became effective August 3 and was announced on August 5 as part of Grayscale’s regular quarterly review process. The Smart Contract Fund tracks the CoinDesk Smart Contract Platform Select Capped Index, which weights assets primarily by market capitalization while imposing concentration limits to maintain diversification. Alongside BNB’s addition, Cardano experienced the largest reduction in weighting, falling to 4.88%, while Hedera (2.08%), Avalanche (1.92%) and Sui (1.90%) rounded out the remainder of the portfolio.
Institutional Interest Shifts Toward BNB
The portfolio reshuffle reflects changing institutional preferences within the smart contract platform sector. While Ethereum and Solana remain the two largest smart contract ecosystems by developer activity and decentralized finance adoption, BNB’s inclusion at the top of the fund suggests Grayscale believes the asset has become increasingly important within the broader blockchain infrastructure landscape.
The BNB Chain has expanded rapidly over the past year, benefiting from growth in decentralized finance, tokenized real-world assets and enterprise blockchain applications. Recent network activity and ecosystem expansion have also contributed to increased institutional attention. Market participants viewed the rebalance as a notable endorsement of BNB’s growing role in the digital asset market. Following the announcement, BNB outperformed several large-cap cryptocurrencies during the trading session, while Ethereum and Solana traded modestly lower.
Grayscale noted that the rebalance was conducted according to the methodology governing the underlying CoinDesk index rather than as a discretionary investment decision.
Broader Fund Changes Extend Beyond Smart Contracts
The Smart Contract Fund was not the only product updated during Grayscale’s quarterly review. The asset manager also rebalanced its Decentralized Finance (DeFi) Fund, increasing exposure to Ondo while trimming Uniswap, and adjusted its Decentralized AI Fund by reducing NEAR Protocol and redistributing capital across the remaining holdings. These changes highlight Grayscale’s ongoing effort to keep its thematic cryptocurrency investment products aligned with evolving market capitalizations and index methodologies.
The Smart Contract Fund itself is designed to provide investors with diversified exposure to leading blockchain platforms that support decentralized applications and smart contracts. Unlike single-asset investment vehicles such as spot Bitcoin or Ethereum ETFs, the fund offers exposure to multiple Layer-1 ecosystems through a single investment product. For BNB, becoming the largest holding represents another milestone in its growing institutional acceptance. While the difference between the top three allocations remains relatively small, the rebalance signals that one of the world’s largest digital asset managers now considers BNB the leading component of its smart contract platform portfolio.
As institutional participation in digital assets continues to broaden beyond Bitcoin and Ethereum, periodic fund rebalances such as Grayscale’s increasingly provide insight into how professional investors are allocating capital across the wider blockchain ecosystem.
