  "topic": "DEX trading volume over time",
  "summary": "Decentralized exchange (DEX) spot trading volume has grown from roughly $115B in 2020 and ~$1T in 2021 to a record ~$4.9 trillion in 2025, with 2024 (~$1.5T) up 138% over 2023 (~$647.6B). DefiLlama tracks cumulative all-time DEX volume above $13 trillion (June 2026). Monthly spot volume peaked around $419.76B in October 2025 (CoinGecko basis); DefiLlama's broader all-chain coverage shows even higher single-month peaks. The DEX-to-CEX spot volume ratio more than tripled from ~6% (Jan 2021) to an all-time high of 37.4% in June 2025 (Solana memecoin mania), settling around 21.2% by November 2025. By market share, Uniswap and PancakeSwap have led for years (Uniswap 35.9% / PancakeSwap 29.5% in Aug 2025), but Solana-native DEXes (Raydium, Jupiter) and Base's Aerodrome surged in 2025 — Raydium briefly overtook Uniswap in monthly volume in Nov 2025 ($124.6B vs $90.5B). NOTE: annual totals differ across sources because some count spot-only and others include perps; figures here are spot unless noted, and confidence is lower where sources disagree.",
