Grayscale completed its second-quarter 2026 rebalance of its multi-asset funds this week, and the DeFi Fund’s new weights quietly reordered the pecking order among four major decentralized finance tokens. Uniswap stayed on top, but only just — and Ondo Finance jumped past Aave into second place.
The headline number that traveled fastest was in Grayscale’s separate Smart Contract Fund, where BNB displaced Ethereum and Solana as the top holding. But the DeFi Fund’s shift is the more interesting one for anyone trying to read institutional positioning in decentralized finance, because it is a case study in what a passive, rules-based rebalance can and cannot tell you.
What actually changed
According to Grayscale’s official announcement and coverage of the filing, the DeFi Fund’s component weights moved as follows between the first and second quarter of 2026:
| Token | Q1 2026 weight | Q2 2026 weight | Change |
|---|---|---|---|
| Uniswap (UNI) | 35.22% | 34.16% | -1.06 pts |
| Ondo (ONDO) | 19.83% | 25.44% | +5.61 pts |
| Aave (AAVE) | 21.36% | 19.97% | -1.39 pts |
| Ethena (ENA) | 12.19%* | 12.19% | roughly flat |
*Ethena was added to the fund in the Q1 2026 rebalance, replacing Aerodrome Finance (AERO), which was removed entirely at that time.
The changes took effect after market close on August 3, 2026, with the rebalancing process completed and reported around August 5–6. No token was added or removed this quarter — the four components stayed the same. What moved was each token’s share of the basket, and that shift was large enough for Ondo to leapfrog Aave into the fund’s second-largest position.
Why Ondo jumped ahead of Aave
The DeFi Fund tracks the CoinDesk DeFi Select Index, a market-cap-weighted methodology. When the fund rebalances, Grayscale does not pick winners; it adjusts holdings so the portfolio matches each component’s proportional share of the combined market capitalization of the basket, as defined by the index provider. In practice, that means Ondo’s relative market cap grew faster than Aave’s or Uniswap’s over the quarter, so more of the fund’s exposure automatically shifted toward it.
Ondo Finance has positioned itself around tokenized U.S. Treasurys and real-world-asset (RWA) products, a category that has drawn steady institutional interest through 2026. Aave, by contrast, is a lending protocol whose token value is more tied to borrowing activity and protocol revenue. A market-cap-weighted index will reflect that kind of category rotation mechanically, without anyone at Grayscale making an active call on which sector “wins.”
Reading a passive rebalance as a signal — carefully
It is tempting to treat any Grayscale fund adjustment as a bet the firm is making on your behalf. That is not quite right here. Three things are worth separating:
- What the rebalance shows: relative market-cap movement among Uniswap, Ondo, Aave and Ethena over one quarter, filtered through a specific third-party index methodology.
- What it does not show: Grayscale’s own view on which protocol has better fundamentals, better governance, or a safer smart-contract track record.
- What it might still be useful for: a dated, sourced data point on how capital-weighted attention within DeFi is shifting, which is different from — but not unrelated to — where flows and building activity are actually going.
The same caution applies to the companion move in Grayscale’s Smart Contract Fund, where BNB’s promotion above Ethereum and Solana reflects market-cap weighting dynamics in that basket, not a discretionary judgment that BNB is the superior smart-contract platform.
What to check before acting on this
If a rebalance like this changes how you think about your own DeFi exposure, verify the details yourself rather than trusting a single secondhand summary:
- Read Grayscale’s own press release for the exact effective date and share-class details.
- Confirm current weights directly from the fund’s factsheet, since quarterly rebalances mean any snapshot goes stale within three months.
- Separate index-driven weight changes from actual protocol news — Aave’s dip in weight this quarter is a relative market-cap effect, not a report of Aave-specific bad news.
- Check whether the product you can actually access (private placement, secondary market, or otherwise) matches the fund being described in headlines.
Bottom line
Grayscale’s Q2 2026 DeFi Fund rebalance is real, dated, and mechanically explainable: Uniswap stayed the largest holding but was trimmed, Ondo’s weight jumped past Aave’s on relative market-cap growth, and Ethena held steady after entering the fund the prior quarter. That is useful as a data point about capital-weighted attention inside decentralized finance. It is not evidence that professional money has picked Ondo over Aave as an investment, and it should not be treated as one.

Frequently asked questions
Grayscale's DeFi Fund (ticker DEFG) is a multi-asset product designed to track the CoinDesk DeFi Select Index, a market-cap-weighted basket of decentralized finance tokens. Its holdings are reviewed and adjusted every quarter.
Effective after market close on August 3, 2026, Grayscale trimmed Uniswap's weighting from 35.22% to 34.16%, while Ondo climbed from 19.83% to 25.44%, overtaking Aave, which fell from 21.36% to 19.97%. Ethena held 12.19%. Uniswap remained the largest single holding.
Not necessarily. The DeFi Fund is index-tracking, not discretionary. Weights shift automatically based on each token's market capitalization relative to the others in the basket, following a published methodology rather than an active manager's judgment call.
Grayscale's multi-asset funds are typically structured as private placements available to eligible investors, with different liquidity and access terms than a listed ETF. Check Grayscale's own product pages for current eligibility and share-class details before assuming retail access.
Quarterly. The Q1 2026 rebalance removed Aerodrome Finance (AERO) and added Ethena (ENA); the Q2 2026 rebalance adjusted the four remaining components' relative weights without adding or removing a token.
