The Ethereum DEX aggregator market landscape has shifted over the past year, moving away from the near-dominance of a single protocol toward a more distributed competitive field.
Kyber currently leads with approximately 31% market share, followed by CowSwap at 22%, while 1inch has seen its share decline from roughly 30% to 15% over the same period. This diversification stands in contrast to broader trends in crypto, where many sectors have seen consolidation.
The all-time view shows 1inch commanding the majority of aggregator volume through 2021-2022, a period that coincided with aggressive liquidity mining campaigns across DeFi. The subsequent erosion of its share as incentives wound down raises a structural question of how much of any aggregator’s volume reflects genuine user preference versus incentive-driven activity.
It is worth noting that this data captures direct-to-aggregator volume only. If a user routes through aggregator A and it internally routes to aggregator B, only aggregator A receives credit. Flash loan trades are also filtered out. This methodology means the figures likely understate the reach of protocols that function as backends for other aggregators.
Whether the current distribution reflects lasting structural change or another rotation driven by incentive cycles will become clearer as token programs mature.
For now, the data suggests the aggregator space on Ethereum is more competitive than it has been in years.
