What is high-frequency trading (HFT) on Polymarket?
HFT on Polymarket means executing trades in under 100 milliseconds by using dedicated Polygon RPC nodes, co-located servers, and optimized transaction submission. HFT bots capture arbitrage opportunities that exist for fractions of a second — too fast for standard bots or humans. They process orderbook updates, calculate edges, and submit signed transactions before competitors.
How much does HFT infrastructure cost for Polymarket?
Running a competitive HFT setup on Polymarket requires dedicated Polygon RPC nodes ($500-$2,000/month), co-located servers near Polygon validators ($200-$500/month), custom mempool monitoring tools, and significant development time. Total monthly infrastructure cost: $1,000-$5,000+. This explains why HFT profits concentrate in very few wallets — the barrier to entry is high.
What percentage of Polymarket arbitrage profits go to HFT bots?
Based on on-chain analysis, approximately 73% of all arbitrage profits on Polymarket are captured by bots executing under 100 milliseconds. The remaining 27% is distributed among bots in the 100ms-10s range. This concentration means retail traders should focus on strategies that don't compete directly with HFT — like temporal arbitrage on 2-15 second windows or asymmetric spread capture.
Can you be profitable on Polymarket without HFT speed?
Yes. HFT captures the fastest arbitrage, but plenty of profitable opportunities exist at 200ms-2s execution speeds. Temporal arbitrage (exploiting Binance lag), asymmetric pair cost optimization, and multi-window accumulation strategies all work at slower speeds. A $6-12/month VPS running Python can consistently capture $200-$1,000+/day in opportunities that HFT bots leave behind.
What is order-flow front-running on Polymarket?
Order-flow analysis involves monitoring pending transactions in Polygon's mempool to predict near-term orderbook changes. By seeing large incoming buy orders before they execute, a bot can position ahead of the price impact. On Polymarket, this means detecting when a large trader is about to move the market and trading in the same direction milliseconds before their order fills.
