Polymarket Oracle: Information Arbitrage Logic

The "Oracle" doesn't predict the future; it identifies the Liquidity Gap between news events and market prices. In this lesson, we learn the technical logic of Information Arbitrage—using AI to process global news feeds faster than the market can react.

🏗️ The Arbitrage Pipeline

Ingestion: Real-time RSS feeds from GDELT and NewsAPI.
Reasoning: Gemini 2.5 Pro performs a "Binary Sentiment Pass" on the headline.
Execution: If sentiment > 0.9, the bot executes a buy order on the corresponding outcome.

🛠️ Technical Snippet: The News Scorer Prompt

### SYSTEM ROLE
You are a High-Frequency Sentiment Analyst. 

### INPUT
Headline: "White House announces new tariff policy."
Market: "Will tariffs be announced by Friday?"

### TASK
Score the probability (0-1) that this headline resolves the market.
Constraint: Zero nuance. Output only the float.

🔍 Nuance: The 'Laggard' Effect

Prediction markets often lag behind Twitter (X) by 30-120 seconds. An elite bot uses Stream Processing to capture this 60-second window, which represents "Risk-Free" profit if the news is verified.

⚡ Practice Lab: The RSS Scout

Setup: Use the feedparser library in Python.
Scrape: Pull the last 10 headlines from a news source.
Score: Use a model to score each headline against a "Mock Market."
Verify: Note the speed of the AI pass compared to a human reading the same headlines.

📝 Homework: The Arbitrage Logic

Design a logic gate for a "Macro Event" bot. If "Event A" happens, what specific "Market ID" on Polymarket would be most affected? Define the "Linkage" between news and outcome.
