What is Polymarket?

Polymarket is a decentralized prediction market platform where you trade shares representing outcomes of real-world events. If your prediction is correct, shares pay out $1. If wrong, they're worth $0.

Example: "Will it rain tomorrow?"

YES shares trading at $0.65
NO shares trading at $0.35

If you buy YES at $0.65 and it rains:
- You receive $1.00
- Profit: $0.35 (54% return)

If it doesn't rain:
- Shares worth $0.00
- Loss: $0.65

Getting Started

1. Setup Account

1. Visit polymarket.com
2. Connect with email or Web3 login
3. Deposit USDC (Polygon network)
4. Start trading

2. Understanding Shares

Each market has YES and NO shares
- Prices always sum to ~$1.00
- Price = implied probability
- $0.70 YES = 70% chance according to market

You can:
- Buy YES (bet it happens)
- Buy NO (bet it doesn't)
- Sell anytime before resolution

Trading Strategies

1. Information Edge

Strategy: Trade when you have better information than the market

Examples:
- Local knowledge (weather, events)
- Industry expertise
- Early access to data
- Research skills

Process:
1. Find market where you have edge
2. Assess if price reflects your info
3. Size position based on confidence
4. Monitor for new information

2. Arbitrage

Strategy: Exploit price discrepancies

Types:
- Cross-platform (Polymarket vs Kalshi)
- Related markets (correlated outcomes)
- Yes/No mispricing (should sum to $1)

Example:
Market A: "Team wins championship" = $0.40
Market B: "Team makes finals" = $0.35

Arbitrage: Can't win championship without making finals
Action: Buy "makes finals" if you believe championship odds

3. Momentum Trading

Strategy: Follow price trends

Signals:
- Rapid price movement
- Volume spikes
- News catalysts
- Social sentiment

Process:
1. Identify trending markets
2. Confirm with volume
3. Enter with trend
4. Set stop-loss
5. Exit when momentum fades

4. Mean Reversion

Strategy: Bet on overreactions correcting

When to use:
- Sharp moves on minor news
- Emotional/sentiment driven spikes
- No fundamental change

Example:
- Celebrity rumor moves market 20%
- Rumor debunked
- Price should revert

5. Event-Driven

Strategy: Trade around scheduled events

High-impact events:
- Election days
- Earnings releases
- Fed meetings
- Court decisions
- Sports games

Process:
1. Calendar upcoming events
2. Assess current pricing
3. Position before event
4. Or wait for live trading opportunities

Position Sizing

Kelly Criterion

Optimal bet size = (bp - q) / b

Where:
b = odds received (decimal - 1)
p = probability of winning (your estimate)
q = probability of losing (1 - p)

Example:
- Share price: $0.40 (market says 40%)
- Your estimate: 60% chance
- Potential profit if win: $0.60 per share

b = 0.60 / 0.40 = 1.5
p = 0.60
q = 0.40

Kelly = (1.5 × 0.60 - 0.40) / 1.5
Kelly = (0.90 - 0.40) / 1.5
Kelly = 0.33 (33% of bankroll)

Most traders use fractional Kelly (25-50%) for safety

Risk Management Rules

Conservative:
- Max 5% per position
- Max 20% correlated exposure
- Always have exit plan

Moderate:
- Max 10% per position
- Max 30% correlated exposure
- Use stop-losses

Aggressive:
- Max 20% per position
- High conviction trades only
- Accept higher variance

Analysis Framework

Market Efficiency Check

# Questions to ask:

1. Why is this mispriced?
   - Information asymmetry?
   - Emotional trading?
   - Low liquidity?

2. What does the market know that I don't?
   - Check news sources
   - Review trading history
   - Analyze large positions

3. What's my edge?
   - Unique information?
   - Better analysis?
   - Faster reaction?

Probability Assessment

Base rate analysis:
1. Find historical frequency
2. Adjust for current context
3. Compare to market price
4. Identify gaps

Example: "Will Company X beat earnings?"
- Historical beat rate: 75%
- Current conditions: Strong sector
- Analyst sentiment: Positive
- Your estimate: 80%
- Market price: $0.65 (65%)
- Gap: 15 percentage points
- Action: Consider buying YES

Liquidity Analysis

  best_bid: .bids[0],
  best_ask: .asks[0],
  bid_depth: .bids | length,
  ask_depth: .asks | length
}'

Good liquidity indicators:
- Tight spread (<$0.02)
- Deep order book (>$10k each side)
- Active trading (>100 trades/day)

Poor liquidity warnings:
- Wide spread (>$0.05)
- Thin book (<$1k depth)
- Few recent trades

Advanced Techniques

Correlation Trading

Find related markets and trade the spread:

Example:
- "Candidate A wins primary" = $0.60
- "Candidate A wins general" = $0.35

If A must win primary to win general:
- General should be ≤ Primary
- Look for mispricings

Live Event Trading

Strategy for real-time events (sports, elections):

1. Pre-position before event
2. Watch live with market open
3. React faster than market
4. Scale in/out as odds shift

Tools needed:
- Fast data feed
- Quick execution
- Pre-planned scenarios

Hedging

Reduce risk by offsetting positions:

Example:
- Long "Team A wins" at $0.50
- Event: Key player injured
- Hedge: Buy "Team A wins" NO to lock in smaller loss
- Or: Buy related "Team B wins" YES

Cost of hedge = insurance premium
