The Low-Fee Paradox: Fee-Tier Competition and the Winner-Take-Most Equilibrium in Uniswap v3

But when Uniswap introduced a tiny 0.01% fee tier, it triggered a 'winner-take-most' effect that consolidated price discovery into a single pool.

For the average trader, it means the 'decentralized' future is becoming just as concentrated as the old system, just with lower overhead.
From the abstract
We document the emergence of a volatile winner-take-most equilibrium in Uniswap v3 following the introduction of a 0.01% fee tier for WETH/USDC in November 2022. By October 2025 the new tier captures a peak of 78% of trading volume and over 80% of liquidity activity. Informed and predatory order flow migrate disproportionately, generating 4x-7x higher absolute price impact and repeated loss-versus-rebalancing (LVR) spikes above 6x. From mid-2024, however, sophisticated liquidity providers adapt
