# Bankr Polymarket

Interact with Polymarket prediction markets.

## Overview

Polymarket is a decentralized prediction market where users can search markets, view odds, place bets, and manage positions.

**Chain**: Polygon (uses USDC.e for betting)

## Prompt Examples

**Search markets:**
- "Search Polymarket for election markets"
- "What prediction markets are trending?"

**Check odds:**
- "What are the odds Trump wins the election?"
- "Check the odds on the Eagles game"

**Place bets:**
- "Bet $10 on Yes for Trump winning"
- "Place $5 on the Eagles to win"

**View/redeem positions:**
- "Show my Polymarket positions"
- "Redeem my Polymarket positions"

## How Betting Works

- You buy shares of "Yes" or "No" outcomes
- Share price reflects market probability (e.g., $0.60 = 60% chance)
- If your outcome wins, shares pay $1 each
- Profit = $1 - purchase price (per share)

**Example**: Bet $10 on "Yes" at $0.60 = ~16.67 shares. If Yes wins, get $16.67 (profit $6.67).

## Auto-Bridging

If you don't have USDC on Polygon, Bankr automatically bridges from another chain.
