  "summary": "On-chain perpetuals are the largest revenue-generating DeFi vertical and one of its most concentrated. Total perp DEX volume has grown from under $1B/day in 2022 to a multi-trillion-dollar annual market (CoinGecko: top-12 perp DEXes averaged ~$611B monthly in 2026 vs ~$532B in 2025). Hyperliquid, a fully on-chain orderbook on its own L1, is the dominant leader, controlling roughly 38-44% of perp DEX volume in early-to-mid 2026 (and ~70-75% at its 2025 peak), with ~$190B monthly volume in April 2026 and the largest open interest of any DEX. The former 2021-2023 leaders dYdX (off-chain orderbook / Cosmos appchain) and GMX (oracle/pool AMM on Arbitrum) have fallen to single-digit / sub-3% share. The market structure has bifurcated: high-performance on-chain/hybrid orderbooks (Hyperliquid, dYdX, Lighter, Aster, Vertex, Drift) win pro/HFT flow, while oracle-pool AMMs (GMX, Jupiter Perps) serve retail. A wave of newer venues (Aster, Lighter, Variational, Pacifica, Extended, edgeX) emerged in late 2025-2026 and has overtaken Jupiter and dYdX. The options sub-segment is far smaller and consolidating around Aevo (perps + options, off-chain match / on-chain settle) and Lyra/Derive (AMM, migrated to its own rollup), with legacy names like Dopex/Stryke and Premia marginalized. NOTE: figures aggregate multiple secondary sources (DefiLlama API and the DefiLlama/CoinGecko web pages were partly rate-limited/blocked) and vary by snapshot date; treat as directional.",

  "leadership_shift": "2021-2023 (orderbook + AMM duopoly): The market was essentially split between dYdX and GMX. dYdX (off-chain orderbook, later its own Cosmos appchain) led on volume after its Aug-2021 airdrop, holding ~$10B weekly; GMX (oracle-pool AMM, launched Arbitrum Sep 2021) led the AMM wave at ~$2B weekly. 2023 (inflection): Hyperliquid launched ~May 2023 with a fully on-chain orderbook on a custom L1, ran ~$2-3B weekly through end-2023 and flipped GMX. 2024 (the flip): Hyperliquid grew to ~$10B weekly by Aug 2024, flipping dYdX v4; industry perp DEX volume hit ~$1.5T (+138% YoY) with Hyperliquid contributing over half in Q4. 2024-2025 (consolidation): Hyperliquid took ~70-80% peak share (Q2 2025: ~$653B of ~$898B total, ~73%; the ~$898B total is confirmed but Hyperliquid's slice that quarter is methodology-dependent — ~73% per some trackers vs 48.7% / ~$437B per Dune Analytics, so treat the $653B sub-figure as basket-dependent); dYdX and GMX fell to single digits. Late 2025-2026 (fragmentation at the top): New orderbook venues (Aster, Lighter) plus Variational, Pacifica, Extended and edgeX gained ground, briefly cutting Hyperliquid to ~38% before it rebounded to ~44%; these newcomers overtook Jupiter and dYdX. Net result: a decisive shift from the dYdX/GMX duopoly to Hyperliquid dominance, with on-chain/hybrid orderbooks displacing pure oracle-pool AMMs for top flow, and a long tail of fast-rotating challengers. Options remained a small, separate niche consolidating around Aevo and Lyra/Derive while legacy names (Dopex, Premia, Ribbon, Friktion) faded.",
