Lido's stETH has retained its position as the single most-deposited collateral asset across Aave, Spark, and Morpho lending markets, even as Lido's overall share of staked ETH has gradually eroded from its 2024 peak. The post-Pectra environment, in which validators can consolidate stake into single 2,048-ETH nodes and a broader set of staking participants can compete on operational parameters, has structurally narrowed Lido's lead in the underlying staking market. But the network effect of stETH integrations across DeFi has proven much stickier than the upstream staking-share number alone would suggest.
Lido's market share of total staked ETH peaked at slightly over 32% in mid-2024, well below the levels that had triggered earlier debates about validator concentration. Following Ethereum's Pectra upgrade, the share has gradually declined toward roughly 25%, with the lost share split among several smaller liquid-staking providers, restaking-focused alternatives like ether.fi and Renzo, and a growing solo-staking cohort enabled by the lower hardware requirements of the consolidated-validator model. None of those competing providers, however, has matched stETH's footprint inside DeFi's lending markets. Aave, Spark, and Morpho collectively hold over $11 billion in stETH deposits, and the asset routinely accounts for the largest single line item in each protocol's collateral mix.
The persistence is partly a function of liquidity depth. stETH has the deepest secondary-market depth of any liquid staking token — the Curve stETH/ETH pool alone has consistently maintained more than $400 million in liquidity, supplemented by significant depth on Uniswap and Balancer — and lending protocols continue to award it the most generous loan-to-value parameters as a result. A standard stETH position in Aave can be levered up to a 92.5% loan-to-value ratio, materially higher than any competing LST, which translates directly into more capital-efficient looping strategies for sophisticated users. Risk teams at Aave and Spark have publicly defended the elevated LTV on stETH, citing the asset's deep liquidity history, audited oracle inputs, and the fact that it has never traded materially below its underlying ETH peg outside of a few brief stress events.
Newer challengers have claimed share among restaking-curious users without dislodging stETH from its core lending-collateral position. Renzo, Kelp, and ether.fi have built sizable user bases around restaking-yield narratives, and their tokens have accumulated meaningful TVL. But none has been awarded comparable LTV parameters in the major lending markets, and none has matched stETH's secondary-market depth. The result is a bifurcated LST market: stETH dominates collateral usage, while restaking-focused alternatives capture incremental staking deposits. The bifurcation has held with surprising stability through the post-Pectra transition, suggesting that LST market share in the lending stack is governed by different dynamics than market share in the underlying staking layer.
The implications for Lido's competitive position are nuanced. The protocol no longer dominates upstream staking flow — meaningful capital is being directed elsewhere — but it remains structurally embedded in the DeFi capital stack. That embedded position generates significant indirect revenue: stETH integration fees, Curve LP rewards, lending-protocol oracle dependencies. The asset's persistence as a collateral standard also functions as a defensive moat. Any competitor seeking to displace stETH would need to simultaneously match its liquidity depth, its parameter history with risk teams, and its multi-protocol integration footprint — a combination of barriers that no challenger has yet been able to overcome.
The forward question is durability. If a competing LST achieves comparable secondary-market depth and demonstrates a multi-quarter track record of stable peg behavior under stress, lending protocols would likely adjust their parameter sets to grant comparable LTVs. Whether that scenario materializes within the next year depends largely on Renzo, ether.fi, and potentially one of the EigenLayer-aligned LRTs growing their on-chain liquidity to match stETH's. Watchers should focus on Curve and Uniswap depth metrics for the major LST/LRT pairs, lending-protocol parameter governance proposals, and the relative growth rate of stETH versus its closest challengers. For now, Lido's incumbency advantage is intact — but it is no longer the unassailable position it once was.
