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.
