Polymarket's New Fee Structure

Polymarket announced extra fees for its 15‑minute crypto markets to limit high‑frequency algorithmic trading. The fees target bets with near‑even odds, reaching a maximum of 1.56% and dropping toward the extremes of 0% or 100% probability. A portion of the proceeds will be rebated to makers who provide liquidity. The change is marketed as a way to keep fast markets deeper, tighter, and easier to trade.

Bot's Record Gains

The address 0x8dxd, suspected to be an automated trading bot, turned a $300 stake into more than $400,000 in profit. Between Jan 6 and Jan 9 it added 700 predictions, raising one‑month earnings to nearly $512,000 and total profits to over $550,000. The bot focuses on directional bets for Bitcoin, Ethereum, Solana and XRP. It is believed to exploit a slight data lag between major exchanges and Polymarket’s roughly 50:50 odds.

Potential Impact on the Strategy

The new fee schedule directly targets the bot’s likely edge, making trades at 50% odds the most expensive. Although the highest fee stays below 1.56%, it could erode the narrow margins the bot relies on. Rebates for liquidity providers may also alter market dynamics. Consequently, the bot’s future profitability is uncertain under the revised fee regime.
