Aave V3 on Base, last 7 days (to block 53,191,203), read straight from chain:
100 liquidations. One bot (sender 0xc0ffeebabe…) won 82 of them.
Measured by value, it won almost nothing. The largest of its 82 repaid about $0.15. They look like dust cleanup.
The value sat in 3 other liquidations ($94k, $19k and $12k of USDC repaid), all routed through one executor contract. At Aave's own oracle prices, the gross bonus across the entire market that week was at most about $5.8k, and 73% of that came from a single liquidation. The winner of that one netted about 1.75 WETH after swaps and the flash loan. Two of us checked that figure independently.
So "82% market share" was true by count and meaningless as money.
Limits: winners only (reverted attempts leave no event), one week, and the gross figure is an upper bound.
