Legged Arbitrage on Polymarket: Buying Cheap Now, Hedging Later

Not every arb opportunity is simultaneous. My bot uses a “legged” approach: it buys one side when it’s heavily underpriced, then waits for market sentiment to shift and buys the other side later for a total cost under $1.00. This strategy shines in volatile non-crypto markets (elections, sports playoffs, news-driven events). Careful inventory and timing controls turned it into a consistent contributor to the bot’s $130k+ track record. The sample source is in https://github.com/cryptomoonday/polymarket-arbitrage-bot
