SparkLend crosses 600,000 ETH in deposits, setting a new all-time high
The Sky-linked lending protocol keeps pulling in ETH as whales favor conservative DeFi venues
SparkLend now holds 600,000 ETH in deposits, a new all-time high for the lending protocol as of mid-September 2026.
The numbers behind the milestone
The climb has been steady. SparkLend held 380,000 ETH in deposits in late April 2026. By mid-May, that figure had reached 516,000 ETH. Four months later, it crossed the 600,000 ETH line.
The broader balance sheet has grown alongside it. Total market size, meaning the value of all assets supplied to the platform, stands at $7.39 billion as of mid-September 2026.
Total value locked, or TVL, is nearing $4.96 billion. TVL is the standard DeFi yardstick: think of it as the money actually sitting in the vault rather than the money that has walked out the door as loans.
On that front, active loans total roughly $2.4 billion.
Whales have been a big part of the story. Large holders funneled approximately 88,320 ETH into SparkLend over the six months leading up to September 2026.
USDS borrowing and the Sky connection
SparkLend is the flagship lending protocol inside the Spark ecosystem. Spark is tied to Sky, the protocol formerly known as MakerDAO, one of DeFi’s original heavyweights.

Borrowing of USDS on SparkLend has hit new highs, reaching between $800 million and $900 million.
Unlike many lending markets where interest rates float freely with supply and demand, SparkLend sets governance-controlled rates for assets including USDS.
A deliberately narrow playbook
SparkLend does not try to be everything to everyone. Its collateral set is narrow, limited to wstETH, a wrapped form of staked ETH, and previously rETH. It also restricts high-leverage looping compared with peer platforms.
SparkLend fully deprecated its low-usage Gnosis Chain deployment on September 14, 2026. The protocol now focuses exclusively on Ethereum.
Why investors are leaning conservative
Investors have been gravitating toward conservative DeFi protocols following incidents affecting competitor platforms. There is also a broader preference among institutional participants for vetted, lower-risk lending options.
What this means
For Sky, the USDS borrowing figures are arguably the more strategic number. Between $800 million and $900 million in USDS borrowing shows SparkLend working as a distribution engine for the stablecoin, not just a parking spot for ETH.
Whale inflows of approximately 88,320 ETH over six months mean a relatively small number of large holders could move the deposit figures meaningfully if they decide to leave. The Ethereum-only focus also concentrates exposure.
