# 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.

## Market Types

| Category | Examples |
|----------|----------|
| Politics | Elections, legislation |
| Sports | Game outcomes, championships |
| Crypto | Price predictions, ETF approvals |
| Culture | Awards, entertainment events |

## Common Issues

| Issue | Resolution |
|-------|------------|
| Market not found | Try different search terms |
| Insufficient USDC | Add USDC or let auto-bridge |
| Market closed | Can't bet on resolved markets |

## Tips

- Search and check odds before betting
- Start with small amounts to test
- Check market liquidity for best prices
- Redeem promptly after markets resolve

Overview

This skill helps you interact with Polymarket prediction markets: find markets, check odds, place bets, and manage positions on Polygon using USDC.e. It guides searches, explains odds and payouts, and handles auto-bridging of funds to Polygon when needed.

How this skill works

The skill searches Polymarket markets by keywords or categories, fetches real-time prices and implied probabilities, and prepares transactions to buy Yes/No shares. It calculates shares and potential payouts, checks market liquidity and status, and can initiate auto-bridge transfers of USDC to Polygon before placing bets. It also retrieves open positions and redemption options for resolved markets.

When to use it

  • You want to find or filter Polymarket markets (politics, sports, crypto, culture).
  • You need current odds or implied probabilities for a specific outcome.
  • You plan to place a bet or test a small stake on a market outcome.
  • You want to view, manage, or redeem your Polymarket positions.
  • You need to bridge USDC to Polygon automatically before betting.

Best practices

  • Search and review market liquidity and spread before placing a bet to avoid bad fills.
  • Confirm implied probability and compute shares/payouts so you understand risk and reward.
  • Start with small stakes when testing a new market or unfamiliar outcome.
  • Ensure your wallet has enough USDC.e on Polygon or enable auto-bridging ahead of a trade.
  • Avoid betting on markets that are closed or low-liquidity; check market status first.

Example use cases

  • Search Polymarket for upcoming election or sports markets and list top trending markets.
  • Check the current odds and implied probability for a candidate or team.
  • Place a $5–$20 bet on a Yes/No outcome and show expected shares and payout if correct.
  • View your open Polymarket positions, current value, and gas/bridge requirements.
  • Redeem winnings after a market resolves and auto-bridge funds back if needed.

FAQ

How are odds represented on Polymarket?

Odds are shown as share prices (e.g., $0.60 = 60% implied probability). Each winning share pays $1 at resolution.

What happens if I don’t have USDC on Polygon?

The skill supports auto-bridging: it can move USDC from another chain into USDC.e on Polygon before placing a bet, subject to network fees and time delays.

Can I bet on resolved or closed markets?

No. Closed or resolved markets cannot accept new bets. You can still redeem positions if you held winning shares.
