In early May 2026, Grayscale completed its quarterly rebalancing of its crypto industry funds. Notably, the DeFi Fund added Ethena to its portfolio while removing Aerodrome Finance, sparking widespread discussion about shifts in institutional allocation strategies.
As the world’s largest digital asset investment platform by assets under management, Grayscale’s quarterly portfolio adjustments are more than routine internal rebalancing—they reveal the underlying logic of institutional capital when selecting DeFi and infrastructure assets. In this round, Ethena entered the fund with a 13.59% weighting, immediately becoming the fourth-largest holding. In contrast, Aerodrome, which was only added in Q3 2025, was completely removed.
What Are the Specific Changes in the DeFi Fund and Smart Contract Fund This Time?
This adjustment affected both Grayscale’s DeFi Fund and Smart Contract Fund, each following the CoinDesk Index methodology. For the DeFi Fund, Grayscale sold Aerodrome Finance and other existing assets, reallocating the proceeds to Ethena. The updated DeFi Fund holdings are: Uniswap (UNI, 35.22%), Aave (AAVE, 21.36%), Ondo Finance (ONDO, 19.83%), Ethena (ENA, 13.59%), Curve DAO, and Lido DAO at 5.27% and 4.73% respectively.
The Smart Contract Fund saw no additions or removals this quarter, but did adjust the weightings of existing assets. Ethereum (ETH) reclaimed the top spot with a 30.14% weighting, closely followed by Solana (SOL) at 29.69%, together comprising about 60% of the portfolio. Cardano (ADA) holds 17.96%, while Avalanche (AVAX), Hedera (HBAR), and Sui (SUI) account for 7.69%, 7.41%, and 7.11% respectively.
What’s the Rationale Behind Ethena’s 13.59% Weight in the DeFi Fund?
Ethena’s 13.59% weighting makes it the fourth-largest holding in the DeFi Fund, far surpassing the previous weight assigned to Aerodrome (around 5.36%). This significant increase means Ethena entered the fund from a strong starting position, reflecting the index’s comprehensive assessment of its true market depth.
Ethena’s core narrative centers on its synthetic dollar protocol. Unlike fiat-backed or overcollateralized stablecoins, Ethena’s USDe achieves value stability through a unique mechanism: the protocol holds crypto assets and establishes corresponding short positions in derivatives markets. This hedging structure minimizes price volatility risk. The approach is more capital-efficient than traditional overcollateralized stablecoins and transforms stablecoins from simple mediums of exchange into yield-generating assets.
From a fundamental perspective, Ethena made key advances in its economic model in 2026. In Q1, its risk committee confirmed preset parameters for the fee switch mechanism, enabling ENA to transition from a pure governance token to a yield-generating asset. Governance updates show USDe’s total supply held steady at roughly $6.07 billion at the end of February, with staked USDe tokens reaching $3.53 billion—a staking ratio of 57.96%. The APY for staked USDe was 3.59%, consistently outperforming other mainstream stablecoin savings rates under prevailing market conditions.
These combined factors enabled Ethena to meet the market-cap-weighted criteria for inclusion in the CoinDesk DeFi Select Index. Once the index added the asset, Grayscale’s quarterly rebalancing followed suit, bringing ENA into the institutional DeFi portfolio.
Does Aerodrome’s Removal Reveal Institutional Standards for DeFi Project Selection?
Aerodrome Finance (AERO) was added to the Grayscale DeFi Fund in Q3 2025, replacing MakerDAO (MKR), with a weighting of about 6.60%. Yet, just two quarters later, AERO was fully removed, with its weight at exit around 5.36%. This rapid change signals that index-tracking funds strictly adhere to thresholds for liquidity, custody feasibility, and market cap stability. If a project’s quarterly performance deteriorates in quantitative terms, it may trigger removal.
Some operational metrics for Aerodrome during the current evaluation cycle may no longer meet the CoinDesk DeFi Select Index’s inclusion criteria. While the official press release did not disclose specific quantitative reasons for removal, the standardized process illustrates the general institutional logic: DeFi assets must maintain designated liquidity depth, custody compliance, and responsiveness to market events to remain in the index.
Additionally, the quarterly rebalancing system itself is inherently competitive. For institutional capital, periodic recalibration is both routine and a stress test for a project’s fundamentals.
What Does ETH’s Return to the Top Spot in the Smart Contract Fund Signal?
In this round of quarterly rebalancing, Grayscale’s Smart Contract Fund kept its asset structure unchanged but made notable adjustments to weightings. Ethereum regained the top position with a 30.14% weighting, overtaking Solana (29.69%) for the first time since Q4 2025, when SOL had surpassed ETH.
The roughly 0.45 percentage point gap between ETH and SOL may seem minor, but it reflects the fund’s balanced allocation strategy. In the 2026 market landscape, the Smart Contract Fund still follows a market-cap-weighted cap methodology. This means the relative performance of these two ecosystems—including on-chain activity, decentralized application deployments, transaction throughput, and stablecoin deposits—directly influences their dynamic weights. The current allocation shows that institutions are maintaining exposure to Solana’s high-throughput scenarios while also valuing Ethereum’s security and ecosystem depth.
The fund also retains Cardano, Avalanche, Hedera, and Sui as the third to sixth "diversification tier," ensuring risk dispersion at the infrastructure layer.
How Are Ethena’s Ecosystem Fundamentals Performing in Relation to This Rebalancing?
Early 2026 saw market volatility, with USDe supply contracting from its peak. However, after redemption pressures eased at the end of April, USDe stabilized at around $4.28 billion. The protocol’s debt coverage ratio held at 101.11%, and the reserve fund reached approximately $62.5 million, indicating the protocol’s ability to maintain overcollateralization even under stress.
Ethena’s staking activity remains robust. The supply of staked USDe tokens reached 3.53 billion at the start of 2026, with a staking ratio near 58%. Once the fee switch mechanism passes compliance audits and is activated, ENA will directly capture protocol revenue, creating a more complete value capture model. Ethena has also expanded its white-label stablecoin products across multiple blockchains, with total cross-ecosystem circulation surpassing $100 million for the first time at the start of the year. The sustained improvement or stability of these fundamentals is a key prerequisite for ENA’s inclusion in the quarterly index evaluation.
Is Institutional Asset Allocation Undergoing Structural Shifts?
From a macro perspective, institutional capital in crypto is moving from "broad experimentation" to "strategic deepening." For example, in Q1 2026, the DeFi Fund significantly increased allocations to assets with real yields and stablecoin infrastructure attributes. The portfolio is concentrated in staked assets (Lido DAO), on-chain lending (Aave), stablecoin liquidity infrastructure (Curve), and tokenized asset financing (Ondo). The addition of Ethena reinforces the emerging category of "yield-generating stable assets."
The Smart Contract Fund, while keeping its asset lineup unchanged, recalibrated weightings to reflect a strategic intent for balanced bets on mainstream infrastructure. Both funds point to a trend: institutional allocations are shifting from early-stage ecosystem bets to assets with mature product-market fit, verifiable economic models, and sustainable income potential.
Does This Rebalancing Signal a New Structural Allocation Direction?
Grayscale’s quarterly rebalancing essentially follows the CoinDesk index methodology, reflecting not only Grayscale’s preferences as a single manager but also broader institutional standards for "investable assets." Looking ahead, institutional scrutiny in DeFi will likely focus on three dimensions:
First, paradigm innovation in stablecoin infrastructure. Ethena’s inclusion shows that synthetic dollar models based on delta-neutral strategies are now on the mainstream institutional radar.
Second, diversification and sustainability of yield sources. Whether from staking, lending rates, or decentralized trading fee splits, DeFi protocols with sustainable cash flow structures are pulling ahead of pure governance tokens.
Third, compliance and index inclusion as a first-mover advantage. DeFi assets that meet liquidity requirements, custody compatibility, data transparency, and cross-cycle stability will enter institutional portfolios sooner.
Conclusion
Grayscale’s Q1 2026 rebalancing is a textbook data-driven adjustment: Ethena joined the DeFi Fund with a 13.59% weighting, replacing Aerodrome, signaling that institutional capital is prioritizing stablecoin infrastructure logic over DEX trading fee logic. ETH’s return to the top spot in the Smart Contract Fund illustrates a balanced approach at the infrastructure layer. Observed alongside recent survey data showing nearly 80% of institutions plan to allocate to digital assets, this rebalancing helps the market understand the underlying metrics guiding institutional asset selection.
Frequently Asked Questions (FAQ)
Q1: Why did Ethena’s weighting jump straight to 13.59%, instead of a smaller trial allocation?
A: The Grayscale DeFi Fund follows the CoinDesk DeFi Select Index’s market-cap-weighted methodology. Ethena’s market size, liquidity, and custody availability during the evaluation period determined its index weight. The fund purchases assets in proportion to the index composition during rebalancing, so there’s no "trial allocation" phase for valuation adjustments.
Q2: Does Aerodrome Finance’s removal mean the project has major fundamental issues?
A: Removals are based on quantitative index thresholds, including sustained trading volume, liquidity staking, custody feasibility, and market cap stability. The official information did not specify the reasons for removal, so it’s not possible to directly infer major fundamental problems. However, being dropped from the fund does indicate that Aerodrome failed to meet one or more inclusion criteria during this evaluation cycle.
Q3: The ETH and SOL weightings in the Smart Contract Fund are very close. Does this imply institutional disagreement?
A: The narrow gap—about 0.45 percentage points—between ETH and SOL reflects a balanced institutional approach to both ecosystems. The high-low distribution mainly highlights subtle differences in market depth and application metrics at this stage, not a decisive preference. Both assets are expected to remain core holdings in the same portfolio over the long term.
Q4: Does this rebalancing signal a prelude to broader institutional allocation in DeFi?
A: About 66% of institutions have clear expectations for DeFi participation. As the world’s leading digital asset investment platform, Grayscale’s index-driven quarterly rebalancing offers a valuable framework for institutional DeFi asset selection. However, the fund’s net asset value and total AUM remain relatively limited, so this event reflects changing selection standards rather than serving as an independent trigger for large-scale capital inflows.
