A growing chunk of Polymarket's daily volume—at least 15%—now comes from automated bots and algos.
On short-term crypto contracts (5-15 min BTC/ETH/SOL up/down markets, often $50-60M daily), it's closer to ~37-40%.
Recent Dune/Hubble data shows a "Bot Zone" cluster: just 3.7% of addresses drive nearly 37.44% of total platform volume, with extreme patterns like hyper-concentrated trading and ultra-short holds.
