  "summary": "DeFi lending is a ~$40-54B deposit category (DefiLlama lending category, April 2026) dominated by Aave, which holds roughly 60-63% of active borrows (Token Terminal), about 36-42% of the DefiLlama lending category by deposits/TVL, and a ~$13B+ TVL lead over its nearest rival at its April-May 2026 peak (Aave's own TVL had drawn down to ~$12.8B by the 2026-06-16 snapshot). The structure has bifurcated: Aave remains the broad-market, multi-chain incumbent (pooled model), while the fastest growth is in modular/isolated architectures led by Morpho (Morpho Blue primitive + curated Vaults), with Euler V2 staging a post-hack comeback. Spark, the lending/yield arm of Sky (formerly MakerDAO), is the #2-#3 player on the back of Sky's stablecoin reserves. Compound has stagnated as a legacy pooled lender, JustLend dominates Tron, and Kamino leads Solana lending. Figures vary by snapshot date; the most cited April-May 2026 readings are reported below.",

  "leadership_shift": "2018-2020: MakerDAO pioneered on-chain lending with overcollateralized DAI; Compound then ignited 'DeFi summer' (2020) with the COMP liquidity-mining model and briefly led. 2021: A multi-protocol top tier - by Oct 2021 Aave (~$18.9B) had overtaken Compound (~$12B), with MakerDAO (~$16.4B) also huge; Aave won via faster innovation (flash loans, more assets) and aggressive multi-chain/TradFi expansion. 2023: Aave consolidated the #1 spot with V3 and broad multi-chain deployment while Compound stagnated (founder pivoted to Superstate) and Euler suffered a ~$200M hack; MakerDAO spun out SparkLend. 2024-2026: The category split into two tracks - (1) Aave entrenched as the pooled, multi-chain incumbent (~36-42% of the DefiLlama lending category by deposits / ~60-63% of active borrows, ~$13B+ TVL lead at the Apr-May 2026 peak) with Spark as the Sky-backed #2/#3; and (2) a modular/isolated-market wave led by Morpho (Blue primitive + curated Vaults, ~$10B deposits at peak) and a recovering Euler V2. The narrative is specialization rather than displacement: Morpho/Euler grew by pulling capital off monolithic pools with isolated, curator-driven markets and tighter spreads, while Aave defended its liquidity moat. Chain-specific leaders emerged too: JustLend on Tron and Kamino on Solana (~75% of Solana lending).",
