Polymarket Trading Bot Fees Compared: What You Actually Pay

Trading on Polymarket involves three potential cost layers, though not every layer applies to every platform:

• Trading fees: The fee a bot charges per executed trade, typically a percentage of trade size. This is the bot operator's revenue.
• Gas fees: Polygon network fees required to process every on-chain transaction. Typically $0.01–$0.10 per trade — small individually, but they add up for high-frequency traders.
• Platform fees: Polymarket itself charges zero trading fees. There is no middleman fee from the market itself — only gas.

Trading directly on polymarket.com is the baseline: zero trading fees, just gas. Every bot adds a service fee on top of that baseline in exchange for automation features like copy trading, AI predictions, and sniping.

• Share: No direct trading fee — revenue comes from the copy trading creator model (50% of creator earnings goes to creators, Share takes a cut of the remainder). No gas sponsorship; you pay Polygon gas on each trade.
• Polygun: Per-trade fee with fully sponsored gas (zero Polygon fees for users). Net cost may be lower than bots with a lower per-trade rate but no gas sponsorship, especially at volume.
• Polymtrade: Per-trade fee with fully sponsored gas. Similar gas savings to Polygun — both eliminate the need to hold MATIC tokens entirely.
• PolyCop: 0.5% per trade — the lowest explicit bot fee in the category. No gas sponsorship, so add Polygon gas on top for your true cost.
• Ok.bet: Per-trade fee with an $OK token discount option that can reduce your effective rate. No gas sponsorship.
• Polycool: Standard per-trade fee. No gas sponsorship. Fee structure is straightforward with no discount mechanisms.
• Polycule: Standard per-trade fee. No gas sponsorship. Note: Polycule experienced a $230,000 smart contract exploit in January 2026 — a non-financial cost worth weighing when assessing total risk.

The cheapest bot depends on how often you trade:

• Low volume (1–5 trades/week): Share or Polygun. Share charges no direct trading fee; Polygun's gas sponsorship keeps total cost low even at lower volumes.
• Medium volume (daily trading): Polygun or Polymtrade. Sponsored gas saves the most when trades start accumulating — you eliminate $0.03–$0.10 per transaction entirely.
• High volume (multiple trades/day): Gas-sponsored bots (Polygun, Polymtrade) deliver the largest savings. PolyCop's 0.5% rate is competitive, but gas fees without sponsorship stack up fast at scale.

• Polymarket.com direct: Truly free trading — zero trading fees — plus minimal Polygon gas per transaction. The cheapest option for casual or infrequent traders.
• Share: Free trading in the traditional sense. No per-trade percentage fee. Indirect costs exist through the creator revenue model, but you as a copier pay nothing extra beyond gas.
• Gas-sponsored bots (Polygun, Polymtrade): Higher per-trade fee but zero gas. The all-in cost is predictable — just the percentage fee, nothing else.
• Non-sponsored bots (PolyCop, Ok.bet, Polycool, Polycule): Lower or competitive per-trade fees, but Polygon gas stacks on top of every trade. Total cost rises with frequency.

The key insight: total cost depends almost entirely on trading frequency. For fewer than 5 trades per week, any bot's fee structure is nearly equivalent. For 20+ trades per day, the gas sponsorship from Polygun or Polymtrade saves meaningfully more than a lower percentage rate without it.
