Decentralization at risk as 100 wallets hold 80% of DeFi supply: Report

DeFi’s decentralization narrative is now being tested, as governance data reveals power is not widely distributed. The ECB’s March 2026 paper shows the top 100 holders control over 80% of tokens across major protocols, forming a clear concentration.

As this structure persists, decision-making shifts toward a small group, often including treasuries, founders, and centralized exchanges. Delegation intensifies this effect, as just 10–20 voters control up to 96% of delegated power.

Participation remains low at 5–12%, which means most holders do not influence outcomes, leaving control in fewer hands. This imbalance matters because regulators can now identify who shapes protocol decisions.

As frameworks like MiCA tighten, these visible control points increase regulatory exposure. This shift suggests DeFi may face oversight similar to traditional finance structures.

DeFi governance narrows, but who is in control?

DeFi governance is shifting from broad ownership to concentrated control, as delegation hands decision power to a small group. The ECB’s March 2026 paper shows the trend clearly, with the top 20 voters in Ampleforth controlling 96.04% of delegated votes.

As this structure develops, the results rely more on a small number of active delegates than on the larger holder base. Influence clusters quickly, as seen by the fact that Uniswap’s top 18 hold 52% and MakerDAO’s top 10 control 66%.

Nevertheless, since one-third to almost 50% of the top voters cannot be identified, this focus does not translate into obvious accountability. Delegation separates traceable ownership from influence, which is why this occurs.

This creates a market where control is concentrated but partially hidden. As a result, DeFi’s decentralization weakens, while regulatory pressure rises without fully resolving enforceability.
