Sky Protocol's annualized revenue soared to $419 million, sUSDS revenue products attracted $44 mill

Sky Protocol's settlement cycle in the past three months has hit a new high in annualized total revenue, subverting DeFi's inherent perception of lending.

Sky Frontier Foundation disclosed in its June 2026 operating update that the agreement's annualized total revenue operating rate has reached a record high of US$419.08 million, allowing the agreement to cross the threshold that a few decentralized lending platforms have touched. Such a scale of revenue expansion is unusual-sUSDS holders have accumulated more than US$250 million in revenue since its launch, and a new fixed income product has absorbed a total of US$44.1 million in lockup value in its first month of launch.

These numbers are not just due to rising interest rates. They reflect a strategic shift from agreements to structured income products that are similar to institutional money management tools. Sky's reserves also climbed to $82.5 million, an increase of $33.7 million from March, suggesting that the agreement is also building a balance sheet buffer while distributing benefits to savers. This dual behavior-maintaining the high-income engine while replenishing reserves-tells a story that is far more complex than a simple binge of borrowing fees.

Analysis of revenue sources

Most of the revenue comes from the monthly settlement cycle, which normalizes the gains from Sky's core collateral vault and Sky's savings rate mechanism. The savings rate is the main driver of demand and transfers gains to sUSDS holders. Since its launch, the mechanism has cumulatively allocated more than $250 million in accrued income to savers. This figure is cumulative, but the growth rate has accelerated significantly. Combined with an annualized total revenue operating rate of $419 million, this means Sky is not just charging fees from volatile borrowers-it is building a continuous revenue stream from assets that users are willing to hold for the long term.

In June this year, Sky highlighted the shift with a fixed-income product launched through Sky.Money and Pendle Finance. The product provides predefined returns for sUSDS, with a total locked value of US$44.1 million in its first month of launch. This suggests that institutions and high-net-worth people have a clear need for DeFi tools to eliminate uncertainty about floating interest rates. For Pendle, this means more principal and income tokens available for tokenization; for Sky, it means a more stable deposit base and a new charging layer.

Grove token and proxy ecosystem expands

Meanwhile, Grove, one of Sky's Prime Agents, launched its GROVE governance token in June. Prime Agents are no ordinary players, they manage large-scale operations within the Sky ecosystem, and the launch of governance tokens demonstrates their intention to give these operators financial incentives and voting rights. Although this update does not disclose Grove's total lockup value or fee structure, its launch timing deserves attention. This coincides with the fact that real-world asset tokenization has exceeded US$20 billion on the chain, and a large amount of traditional capital is pouring into agreements that can generate predictable returns from diversified collateral. Grove's actions show that the agent layer within Sky is becoming an independent economic unit, rather than just a maintenance function.

Concerns behind operating rates

Record annualized revenue operating rates do not guarantee sustainable profit margins. 4.19 The US$100 million figure is based on retrospective data from the past three settlement cycles and captures a moment when stablecoin yields remain high and risk appetite drives more capital flows into DeFi. If interest rates narrow, or agreement revenue shifts to provide fee discounts to governance participants, operating rates could cool without warning. The increase in reserves to $82.5 million provides some protection, but remains small relative to the agreed total balance sheet. The real test will be whether Sky can maintain its earnings appeal when volatility in the broader cryptocurrency market returns, or when competitors replicate fixed-income products at lower cost.

In addition, there is uncertainty about how regulators will treat structured income products that fall between deposits and securities. The Sky. Money front end and its partnership with Pendle have attracted much attention because fixed income products often resemble regulated tools in traditional finance. Although no enforcement action has yet occurred, any DeFi protocol that shifts from variable-rate loans to structured fixed-income products faces hidden regulatory risks. For now, the market is betting that revenue numbers are enough to override this concern.

It is clear that Sky has moved beyond the simple over-mortgage model defined in the early MakerDAO era. Today, it is operating multiple revenue streams-treasury fees, savings rate spreads, agency economics, and earnings tokenization cooperation-while accumulating reserves. The $44.1 million fixed-income product launch is small compared to the $419 million operating rate, but it points to where the next growth point may come from. If sUSDS becomes the preferred cash management tool for DeFi funds and high-net-worth individuals, the economic characteristics of the agreement will begin to become less like a peer-to-peer lending pool and more like a decentralized income infrastructure layer. This is exactly the structural shift that June data suggests-although it has not yet been fully confirmed.
