Decentralized exchanges (DEXs) are now handling 23% of the spot trading volume processed by combined centralized exchanges (CEXs), including Binance, Coinbase and others, according to the supplied market data. That marks a record level, with DEX market share up more than 1,100% over the past five years.
The shift has come even as trading activity across both segments contracts. Analysts describe the gain as an important milestone for DeFi, while cautioning that the trend is more nuanced than a simple transfer of users from centralized to decentralized venues.
Gaining share by shrinking more slowly
Analyst Mago identified a pattern behind the rising share. DEX volume fell 55% year-on-year, from $588 billion in 2025 to $262 billion in 2026, yet DEX market share rose from 17.5% to 23.2% over the same period.
In that sense, DEXs did not take share by growing. They took it by shrinking more slowly than CEXs. When the market cools, CEX flow leaves, while on-chain flow sticks, according to the analysis.
Uniswap and PancakeSwap lead DEX volumes
In monthly spot volumes, Uniswap and PancakeSwap dominated with 36% of all DEX volumes. Aerodrome ranked third and PumpSwap fourth.
The largest surge in 2026 occurred in July, when DEX market share rose from 18% to more than 22%. The move coincided with a broader market rebound, as Bitcoin recovered from below $57.8K to over $60K and extended its recovery to over $87K in August and September.
DEX market share had doubled between 2024 and 2025, but later remained flat during the bear market in early 2026.
Security concerns cut both ways
Andy Cavanaugh, founder of The Rollup, argued that the $6.3 billion Binance hack, following Bitget's $388 million exploit in September, will further boost the trend. He described a major shift over 48 hours, with on-chain activity favored over off-chain activity.
Some data points support that view. Hyperliquid's share of aggregate CEX volume increased from 8.0% to 8.3% during the Binance hack. On an individual basis, Hyperliquid was handling the equivalent of 14.5% of Binance's volume, up from a 13.5% low in mid-October.
However, the case is not one-sided. Most DEXs may not fully repay users in the event of hacks in the way Binance or Bitget did, according to the source. Rising AI-enabled security risks across self-custody and other segments could also keep flows sticky or push traders back to CEXs.
Separately, Blockaid flagged an attack targeting the front ends of 12 DeFi projects this week, underscoring that hacks are not isolated to centralized exchanges alone. It remains to be seen whether security risks will ultimately drive DEX market share in the future.
What to watch
DEX spot trading market share reached a record 23% in October, and analysts believe the Binance hack may accelerate DEX trading dominance. The coming months will show whether that shift persists, or whether security concerns and market conditions pull activity back toward centralized venues.
