Polymarket Automation Beyond Bitcoin Bots

Polymarket's Liquidity Rewards Program incentivizes users, known as liquidity providers, to place limit orders close to a market's midpoint. This activity helps maintain a balanced and active market, and the rewards are paid out daily to the providers' wallets. The total rewards and the maximum allowable spread to earn them vary by market. Automated bots on Polymarket often engage in a strategy called intra-market arbitrage. This involves simultaneously buying "YES" and "NO" shares for a specific event when their combined price is less than $1, which guarantees a profit when the market resolves. For instance, if "YES" shares are at $0.48 and "NO" shares are at $0.49, a bot can purchase both for $0.97 to secure a $1 payout. Another common automated strategy is market making, where bots provide liquidity to both sides of a market to profit from the bid-ask spread. These bots constantly monitor order book depth and adjust their limit orders, sometimes withdrawing liquidity just before major news events to manage risk. This steady, less glamorous approach contrasts with high-risk directional betting. Copy trading bots represent another facet of automation, allowing users to automatically replicate the trades of historically profitable wallets. These bots monitor on-chain activity and execute trades based on pre-set rules for position sizing, enabling less experienced traders to mirror the strategies of more successful participants. The platform's infrastructure is a hybrid system, combining off-chain order matching with on-chain settlement on the Polygon network. This design is intended to provide low-latency trading while maintaining the security of on-chain transactions. Developers and traders can interact with the platform programmatically through a set of APIs. The Gamma API is used for discovering market data, while the CLOB (Central Limit Order Book) API handles trading operations like placing and canceling orders. This accessibility has been crucial for the development of sophisticated, high-speed trading bots. Between April 2024 and April 2025, arbitrage traders on Polymarket reportedly earned over $40 million. However, these gains were concentrated among a small percentage of users, highlighting the competitive environment where low-latency infrastructure and efficient bot design are critical for success.
