News Arbitrage / Information-Latency Edge

Latencyscore 4found Jun 24, 2026github.com/benjee-inc/polymarket-arb-dashboard

Exploit the lag between public news events breaking and Polymarket prices updating by rapidly trading affected markets before the crowd reprices them.

How It Works The benjee-inc/polymarket-arb-dashboard is described as a "news arbitrage bot dashboard," indicating a strategy that monitors news feeds (RSS, Twitter/X, news APIs) for resolution-relevant events and trades ahead of the broader market repricing. When a news event directly determines the outcome of an open Polymarket market (e.g., a vote outcome, a sports score, an economic data release), there is a brief window before Polymarket prices reflect the new information.

Entry / Exit Conditions Entry: immediately upon detecting a news event that materially changes the probability of a market outcome, place a large order in the correct direction before prices update. Exit: hold to resolution (since the outcome is now near-certain) or sell once prices have fully repriced to lock in gains without resolution risk.

Verified Results No verified results are provided. The repository has 0 stars and 0 forks. News arbitrage is a well-documented strategy in prediction markets and is the primary edge exploited by sophisticated participants; the competitive landscape is intense.

Implementation Notes The dashboard framing suggests real-time monitoring of multiple markets and news sources with visual alerts. Effective implementation requires extremely low-latency news ingestion (direct API connections to wire services, WebSocket feeds), fast NLP or rule-based classification of news relevance to open markets, and pre-staged orders ready to fire. The edge window is typically seconds to minutes.

Risks - Competition: professional firms with co-located infrastructure and direct news feeds dominate this space; retail implementations are unlikely to be fast enough. - False positives: misclassifying irrelevant news as resolution-relevant leads to losing trades. - Oracle lag: even if the trader knows the outcome, Polymarket's resolution oracle may take hours to settle, during which price may not fully converge. - Liquidity: in fast-moving situations, order books thin out rapidly, limiting fill size.
