Market Creation

The process of proposing, designing, and launching a new prediction market for trading.

#Definition

Market Creation is the process of establishing a new prediction market, including defining the question, setting resolution criteria, providing initial liquidity, and opening it for trading. Depending on the platform, markets may be created by the platform itself, approved users, or anyone willing to stake capital.

#Who Can Create Markets?

#Platform-Created (Centralized)

Kalshi, PredictIt

  • Only platform staff can create markets
  • CFTC regulatory oversight requires vetting
  • Professional curation and legal review
  • Standardized contract templates

Pros:

Cons:

  • Limited selection
  • Slower to market
  • No niche/experimental markets

#User-Created (Permissionless)

Polymarket, Manifold Markets, Omen

  • Anyone can propose markets (with requirements)
  • Decentralized or semi-decentralized approval
  • Wide variety of topics

Pros:

  • Rapid response to events
  • Long-tail markets
  • Innovation and experimentation

Cons:

  • Variable quality
  • Potential for abuse
  • Ambiguous rules

#Hybrid Approaches

Augur v2

  • Permissionless creation
  • REP token staking required
  • Dispute/validation by token holders

Prediction Market DAO

  • Community proposes
  • Governance vote approves
  • Creator earns fee share if successful

#Market Creation Process

#Step 1: Propose Question

Define what you're predicting:

Good questions:

  • "Will Bitcoin trade above $100,000 before Jan 1, 2026?"
  • "Who will win the 2024 U.S. Presidential Election?"
  • "Will Fed raise rates at Dec 2025 meeting?"

Bad questions:

  • "Will Bitcoin go up?" (no specific target/timeline)
  • "Who's the best president?" (subjective)
  • "Secret military operation success?" (unverifiable)

#Step 2: Define Outcomes

Specify possible results:

Binary: YES / NO Categorical: Multiple mutually exclusive options Scalar: Numeric range

Example:

Question: "What will be unemployment rate in Dec 2025?"
Outcomes:
- Scalar market: 0% to 10% range
- Or categorical: <3%, 3-4%, 4-5%, 5-6%, >6%
- Or binary: "Will unemployment be <4%?" YES/NO

#Step 3: Set Resolution Criteria

Define how market resolves:

Resolution Source: Bureau of Labor Statistics
Specific Data: "Unemployment Rate (U-3)"
Release Date: First Friday of January 2026
Backup Source: If BLS unavailable, use ADP National Employment Report
Edge Cases: If BLS revises data within 7 days, use revised figure

#Step 4: Determine Timeline

Set key dates:

  • Creation date: When market opens for trading
  • Close date: When trading stops
  • Resolution date: When outcome determined
  • Settlement date: When payouts distributed

Example:

Created: Nov 1, 2025
Close: Dec 31, 2025 23:59 UTC (betting stops)
Resolution: Jan 3, 2026 (BLS releases data)
Settlement: Jan 4, 2026 (payouts sent)

#Step 5: Provide Initial Liquidity

Most platforms require creator to:

AMM Platforms:

  • Deposit liquidity pool (e.g., $1,000)
  • Sets initial price (e.g., 50/50)
  • Earns trading fees

Order Book Platforms:

  • Place initial limit orders
  • Or subsidize market maker
  • Or no requirement (liquidity arrives organically)

Example - Polymarket:

Creator deposits: $500 USDC
Initial price: 50¢ YES / 50¢ NO
Trading fee: 2%
Creator earns portion of fees

#Step 6: Stake/Bond

Some platforms require creator stake:

Purpose:

  • Ensures honest resolution
  • Prevents spam markets
  • Incentivizes quality

Typical amounts:

  • Augur: ~$50-200 in REP tokens
  • Polymarket: Variable based on market type
  • Manifold: Mana (play money) stake

What happens to stake:

  • Returned if market resolves fairly
  • Slashed if dishonest resolution
  • Partially returned if market voids

#Step 7: Market Goes Live

Once created and approved (if needed):

#Market Creation Requirements

#Technical Requirements

Smart Contract Parameters (crypto platforms):

{
  question: "Will Bitcoin reach $100k in 2025?",
  outcomes: ["YES", "NO"],
  creator: "0x1234...",
  oracle: "UMA Optimistic Oracle",
  closeTime: 1735689599, // Unix timestamp
  category: "Crypto",
  tags: ["Bitcoin", "Price"],
  fee: 0.02, // 2%
}

Platform Metadata:

  • Market title and description
  • Category/tags for discovery
  • Related markets
  • Links to context/sources

#Economic Requirements

Minimum Liquidity (varies by platform):

  • Polymarket: ~$100-500 initial liquidity
  • Manifold: 100 Mana
  • Kalshi: N/A (platform provides)

Fee Structure:

  • Trading fees (1-5%)
  • Resolution oracle fees (0-1%)
  • Creator fee share (10-50% of trading fees)

CFTC-Regulated (Kalshi):

  • Cannot be "gaming or contests of chance"
  • Must have economic purpose
  • Cannot manipulate underlying event
  • Must meet contract designation requirements

Crypto Platforms:

  • May have geographic restrictions
  • KYC requirements in some jurisdictions
  • Prohibited topics (violence, illegal activity)

#Market Creation Costs

#Direct Costs

ItemTypical CostNotes
Liquidity deposit$100-1,000Returned when market closes
Bond/stake$50-500Returned if honest resolution
Gas fees (crypto)$5-50One-time blockchain transaction
Platform fee$0-100Some platforms charge creation fee

#Opportunity Costs

  • Capital locked: Can't use funds elsewhere
  • Time commitment: Writing rules, monitoring, resolving
  • Reputation risk: Bad markets hurt creator credibility

#Potential Revenue

Fee sharing:

Example:
Market generates $10,000 volume
2% trading fee = $200 total fees
Creator gets 30% = $60 revenue

Minus:
Initial liquidity: $500 (returned)
Bond: $100 (returned)
Gas fees: $10 (not returned)

Net profit: $60 - $10 = $50

#Market Creation Best Practices

#1. Clear, Unambiguous Questions

✅ "Will Bitcoin (BTC/USD on Coinbase) close above $100,000 on any day in 2025?" ❌ "Will Bitcoin moon in 2025?"

#2. Objective Resolution Sources

✅ "Based on official U.S. Bureau of Labor Statistics release" ❌ "Based on my judgment"

#3. Appropriate Timeline

  • Not too short (need time for information gathering)
  • Not too long (capital locked, interest wanes)
  • Typical: 1 week to 12 months

#4. Address Edge Cases

Include in rules:

  • Event postponement
  • Source unavailability
  • Ambiguous outcomes
  • Multiple valid answers

#5. Sufficient Liquidity

Provide enough liquidity for meaningful trading:

  • Minimum $100 for niche markets
  • $500+ for popular topics
  • $1000+ for high-interest events

#6. Promote Your Market

  • Share on social media
  • Post in relevant communities
  • Explain why market is interesting
  • Highlight unique angle or information

#Platform-Specific Creation

#Polymarket

  1. Connect wallet
  2. Navigate to "Create Market"
  3. Fill out market details
  4. Deposit USDC for initial liquidity
  5. Submit for review (if required)
  6. Market goes live

Approval process:

  • Automated for standard markets
  • Manual review for sensitive/complex topics

#Manifold Markets

  1. Sign in
  2. Click "Create Market"
  3. Choose type (binary, multiple choice, free response, numeric)
  4. Set question and rules
  5. Add initial liquidity (Mana)
  6. Publish immediately

No approval needed - fully permissionless

#Kalshi

  • No user creation allowed
  • Submit suggestions via feedback form
  • Platform may create if suitable
  • Legal/regulatory review process

#Common Market Creation Mistakes

#1. Vague Questions

Problem: "Will Candidate X do something big?" Fix: "Will Candidate X announce their campaign by [specific date]?"

#2. Subjective Resolution

Problem: "Who gives the best speech?" Fix: "Who wins Gallup poll for best speech?"

#3. Insufficient Liquidity

Problem: 10poolformajorpoliticaleventFix:Atleast10 pool for major political event Fix: At least 500 for high-profile markets

#4. Unclear Timeline

Problem: "Before next year" Fix: "By December 31, 2025 23:59:59 UTC"

#5. No Edge Case Handling

Problem: Silent on postponement Fix: "If event postponed >30 days, market voids"

#6. Unreliable Sources

Problem: "Based on @randomtwitter account" Fix: "Based on official .gov website"

#Market Creation Economics

#Creator Incentives

Fee revenue: Share of trading fees Reputation: Build track record Information: See aggregated beliefs Impact: Influence discourse on topic

#Creator Risks

Liquidity lock-up: Capital unavailable Slashing: Lose stake if dishonest Gas costs: Non-recoverable Opportunity cost: Better uses of time/money

#When Creation Makes Sense

Create a market when:

  • ✅ No existing market on topic
  • ✅ You have unique insight/information
  • ✅ Expected volume > $1,000
  • ✅ Clear, objective resolution possible
  • ✅ Public interest exists

Don't create when:

  • ❌ Similar market already exists
  • ❌ Resolution is subjective
  • ❌ Event too niche/obscure
  • ❌ Timeline too short or too long
  • ❌ Legal/ethical concerns

#The Future of Market Creation

Emerging trends:

AI-Assisted Creation:

  • Auto-generate rules from question
  • Suggest resolution sources
  • Identify ambiguities

Conditional Market Chains:

  • Create dependent markets automatically
  • "If X, then Y" structures

Template Libraries:

  • Reuse proven market structures
  • One-click creation from templates

DAO Governance:

  • Community votes on market approvals
  • Decentralized quality control
  • Token-weighted curation

#Market Creation Template

Copy this for your own markets:

Title: Will [Event] happen by [Date]? Description: This market resolves to "Yes" if [Official Source] reports [Specific Metric] > [X] before [End Date]. Resolution Source: [Link to Source] Resolution Criteria:

  • Primary: [Specific data point]
  • Backup: [Alternative source if primary fails]
  • Edge Cases: If event is canceled, market resolves [N/A or No]. Deadline: [Date & Time UTC]
