Decentralized Exchange (DEX) volumes have sharply declined to $6.047 billion by May 28, 2026, according to DeFiLlama data. This marks a significant drop from $22 billion in January 2026 and a stark contrast to the $159 billion peak in October 2025. The decline follows a consistent downward trend since the October 2025 market crash, with weekly volumes now around $40 billion, a 76% decrease from early 2025 levels. Despite the downturn, Uniswap, PancakeSwap, and Aerodrome Finance remain dominant players in the market. Uniswap recorded $1.428 billion, PancakeSwap $805.97 million, and Aerodrome $798.11 million in trading volumes. The drop in DEX activity reflects a broader market sentiment shift, with investors gravitating towards stablecoins and reducing altcoin exposure. However, lower DEX volumes do not necessarily signal the demise of DeFi, as the sector has historically rebounded from similar downturns.
