A Technical Guide To Prediction Markets
A Comprehensive Typology of Forecasting Projects
Prediction markets represent a rapidly evolving intersection of economics, technology, and collective intelligence. Sometimes referred to as ‘information markets’, ‘idea futures’ or ‘event futures’, prediction markets where participants trade contracts whose payoffs are tied to a future event, thereby yielding results that can be interpreted as market-aggregated forecasts.
Prediction markets are contract-based markets that track the outcome of specific events.
This piece provides a comprehensive technical analysis and classification system for contemporary forecasting projects, whilst examining their underlying mechanics, technological infrastructure, and operational tradeoffs.
I do this through systematic categorization based on prediction type, resolution mechanisms, technical architecture, and incentive structures, also identify several distinct types of prediction market platforms and analyze their respective strengths, weaknesses, and real-world implementations.
#1 Prediction Type and Complexity in Prediction Markets
Prediction markets generate forecasts by aggregating participant inputs, with the type and complexity of predictions shaping their technical design, computational demands, and market applicability. This typology classifies platforms by the nature of their predictive outputs; Binary, Scalar (Numerical), and Combinatorial (Multi-Outcome), each requiring distinct algorithms, data structures, and computational resources
1. Binary Prediction Markets
Binary prediction markets resolve to simple yes/no or true/false outcomes, making them the least computationally complex. They are ideal for event-based forecasts, for exmple“Will Candidate X win the 2026 election?”) and rely on classification algorithms like logistic regression, decision trees, or simple majority voting to aggregate participant bets.
In decentralized platforms, smart contracts encode binary logic, while centralized platforms use internal databases. The market aggregates participant stakes (share purchases for “Yes” or “No”) to estimate probabilities, often represented as prices between 0 and 1.
Technical Details:
Aggregation: Market prices reflect the weighted average of participant bets, interpreted as the probability of the “Yes” outcome.
Resolution: A binary condition (e.g., event occurred or not) triggers payouts, with winners receiving a fixed payoff.
Algorithms: Logistic regression or majority voting aggregates predictions, minimizing computational overhead.
Data Structure: Simple key-value stores or smart contracts suffice, storing bets and outcomes.
Mathematical Formula (Market Probability):
Let Syes and Sno be the total stakes (e.g., funds or shares) on “Yes” and “No” outcomes. The implied probability of “Yes” is:
The payout for a winning share is:
Code Example (Solidity for Binary Market):
// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;
contract BinaryMarket {
uint256 public yesShares;
uint256 public noShares;
bool public resolved;
bool public outcome; // True for Yes, False for No
mapping(address => uint256) public yesBets;
mapping(address => uint256) public noBets;
function bet(bool _choice) public payable {
require(!resolved, "Market resolved");
if (_choice) {
yesShares += msg.value;
yesBets[msg.sender] += msg.value;
} else {
noShares += msg.value;
noBets[msg.sender] += msg.value;
}
}
function resolveMarket(bool _outcome) public {
require(!resolved, "Market already resolved");
outcome = _outcome;
resolved = true;
// Payout logic: Winners receive 1:1 based on shares
}
function getProbability() public view returns (uint256) {
if (yesShares + noShares == 0) return 0;
return (yesShares * 100) / (yesShares + noShares); // Probability as percentage
}
}This contract tracks bets on a binary outcome and calculates the implied probability.

2. Scalar (Numerical) Prediction Markets
Scalar prediction markets forecast continuous numerical values (e.g., “What will Tesla’s stock price be in 2026?”), requiring regression models or optimization techniques like least squares to aggregate participant predictions. These markets are more complex than binary ones, as they handle a range of outcomes rather than a single yes/no decision. Participants submit numerical predictions, often weighted by stake or confidence, and the market aggregates these into a final value, typically the median or mean. Resolution compares the aggregated prediction to the actual outcome, with payouts based on accuracy.
Technical Details:
Aggregation: Predictions are combined using weighted averages or medians, optimized to minimize error (e.g., mean squared error).
Resolution: The actual outcome determines payouts, often proportional to prediction accuracy.
Algorithms: Linear regression, kernel methods, or robust statistics handle outliers and noise.

3. Combinatorial (Multi-Outcome) Prediction Markets
These type of prediction markets handle interdependent or multi-faceted outcomes, predicting across multiple variables or scenarios (e.g., “Which company and region will lead EV sales in 2026?”).
These are the most complex, requiring graph-based algorithms, clustering, or ensemble models to aggregate predictions and account for dependencies. Participants bet on combinations of outcomes, and the market computes probabilities for each scenario, often using simulations or Bayesian networks. Resolution involves verifying multiple conditions, increasing computational and data demands.
Technical Details:

#2 Outcome Resolution and Verification Mechanisms
Outcome resolution and verification mechanisms are critical to ensuring trust, accuracy, and fairness in prediction markets. These mechanisms determine how platforms confirm the outcome of events (e.g., election results, price movements) and distribute payouts to participants. The choice of mechanism impacts speed, scalability, cost, and reliability, particularly in real-time or uncertain environments. This section explores four primary approaches; Oracle-Based, Human-Reviewed, Automated Feed-Based, and Hybrid Resolution.
1. Oracle-Based Resolution
How It Works
Oracle-based resolution relies on external data feeds, typically provided by decentralized oracles like Chainlink or Pyth, to deliver real-world data to smart contracts on a blockchain. These oracles act as bridges between off-chain data sources (e.g., election results, sports scores) and on-chain logic. The process is fully deterministic, with smart contracts automatically executing payouts based on the oracle’s data. Oracles aggregate data from multiple sources to ensure accuracy, often using a weighted average or median to mitigate manipulation risks.
Technical Workflow:
Market Creation: A smart contract defines the event (e.g., “Will Bitcoin exceed $100,000 by December 2025?”) and specifies an oracle as the data source.
Data Fetching: At resolution time, the oracle queries external APIs (e.g., news outlets, price feeds) and submits the result to the blockchain.
Verification: The smart contract validates the oracle’s input (e.g., checking signatures or consensus among multiple oracle nodes).
Payout: The contract distributes funds to winners based on the resolved outcome.
Code Example (Solidity for Chainlink Oracle Integration):
// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;
import "@chainlink/contracts/src/v0.8/interfaces/AggregatorV3Interface.sol";
contract PredictionMarket {
AggregatorV3Interface public oracle;
address public owner;
bool public resolved;
int public outcome;
constructor(address _oracle) {
oracle = AggregatorV3Interface(_oracle);
owner = msg.sender;
resolved = false;
}
function resolveMarket() public {
require(!resolved, "Market already resolved");
(, int price,,,) = oracle.latestRoundData(); // Fetch latest data from Chainlink
outcome = price;
resolved = true;
// Distribute payouts based on outcome
}
}This contract queries a Chainlink price feed to resolve a market (e.g., ETH/USD price).
Real-World Examples
Polymarket: Uses Chainlink oracles on Polygon to resolve markets. Oracles fetch data from trusted APIs and smart contracts settle bets. Fit: Fully deterministic, leveraging blockchain for immutability and oracles for off-chain data.
Aavegotchi (Prediction Markets): A DeFi protocol on Polygon that experiments with prediction markets for gaming/NFT events, using Chainlink for outcomes like tournament results. Fit: Relies on oracle data for fast, automated resolution without human intervention.
Kleros Court (Oracle Component): While primarily a dispute resolution platform, Kleros integrates oracles to provide initial data for prediction market outcomes (e.g., event verification), with smart contracts finalizing payouts. Fit: Oracles supply deterministic inputs for on-chain execution.
SWOT Analysis

Cost Volatility: Fluctuations in oracle token prices or gas fees could deter users during market spikes.
2. Human-Reviewed Resolution
This type of prediction market relies on expert or community consensus to determine event outcomes, often using judgmental aggregation algorithms like the Delphi method. This approach is suited for subjective or ambiguous events (e.g., “Will AI surpass human intelligence by 2030?”) where automated data is unavailable or unreliable. Platforms collect votes or opinions from designated reviewers, aggregate them (e.g., via weighted majority or Bayesian methods), and resolve the market. In decentralized systems, this may involve staking or incentives to ensure honest reporting.
The Delphi method uses iterative consensus building:
ConsensusLevel = 1 - (σ / μ)
Where:
σ = standard deviation of expert opinions
μ = mean of expert opinions
Real-World Examples
SAP Analytics Cloud (Delphi-Method Tools): While not a traditional prediction market, it uses human-reviewed forecasting with Delphi-style consensus for business predictions (e.g., sales forecasts). Experts iteratively refine predictions off-chain, aggregated centrally for resolution.
Manifold Markets: A semi-decentralized platform for community-driven predictions, using human moderators (trusted reveiwers) to resolve niche markets (e.g., cultural events).
SWOT Analysis

4. Hybrid Resolution
Hybrid resolution markets combines automated data feeds (e.g., oracles, APIs) with human review or dispute mechanisms to balance speed, accuracy, and robustness. Typically, an automated system provides an initial outcome, which can be challenged by human validators (e.g., community voters, experts) if disputes arise. This is common in decentralized platforms where oracles supply data, but human oversight ensures fairness for ambiguous or contested outcomes. The process leverages smart contracts for automation and on-chain governance for disputes.
Real-World Examples
Augur (Turbo): Uses Chainlink oracles for initial outcomes (e.g., sports results) but allows community disputes with staked voting on Ethereum. Fit: Combines automated speed with human oversight for contested markets.
Reality.eth: A decentralized platform for prediction markets, using oracles for initial data and Kleros-style human arbitration for disputes.
Polkamarkets: Built on Polkadot, it uses oracles for primary resolution (e.g., price feeds) but incorporates community governance for disputes. It balances scalability and fairness for diverse markets.

#3 Technical Infrastructure and Deployment
This is the underlying architecture of prediction market platforms, determining how they handle operations like market creation, trading, resolution, and settlements. This typology is crucial for balancing decentralization, scalability, cost, and reliability. Platforms are categorized into Fully On-Chain (all operations executed via blockchain smart contracts for maximum transparency), Fully Off-Chain (centralized systems using proprietary servers for efficiency and compliance), and Hybrid (a blend of on-chain and off-chain elements for optimized performance). This section explains each category's mechanics, highlights protocol examples, and provides a SWOT analysis emphasizing technical implications.
1. Fully On-Chain Infrastructure and Deployment
Fully on-chain platforms execute all core functions like market creation, order matching, trading, resolution, and payouts directly through blockchain smart contracts, without relying on external off-chain components like oracles or centralized servers. Users interact via wallets (e.g., MetaMask), and all data is stored immutably on the blockchain. Market creation involves deploying a smart contract defining the event (e.g., binary or scalar outcomes) and parameters (e.g., collateral token). Trading uses automated market makers (AMMs) or order books encoded in contracts, where liquidity is provided by staked tokens. Resolution occurs via on-chain governance (e.g., community voting encoded in the contract) or predefined logic (e.g., comparing to native blockchain data like token prices). Payouts are automatic upon resolution, redistributing collateral to winners.
Platform Examples
Opinion Labs (O.LAB): O.LAB enables permissionless market creation for events like economic indicators or crypto trends, using on-chain optimistic oracles for resolution. All operation are fully on-chain, from market deployment to voting-based settlements, are handled by smart contracts, with no external data feeds.

3. Hybrid Infrastructure and Deployment
Hybrid platforms combine on-chain elements (e.g., smart contracts for settlements, tokenization) with off-chain components (e.g., oracles for data, centralized order books for matching) to balance decentralization with efficiency. On-chain operations, typically on Layer 2 chains, handle trustless tasks like collateral locking and payouts. Off-chain systems manage high-latency tasks, such as order matching via centralized APIs or data fetching via oracles. Market creation may start with an off-chain UI but deploys a smart contract. Trading uses off-chain signed orders (e.g., EIP-712) for speed, batched on-chain for settlement.
Platform Examples
Limitless: Beta-launched in 2024 on Base, with $300 million+ volume by mid-2025, using CLOB for liquidity-trained predictions, with on-chain Base settlements and off-chain APIs/oracles for data, plus centralized UI for accessibility.
Gensyn Judge: Unveiled in September 2025 on a custom chain, using AI for scalable resolutions, with on-chain contracts and off-chain AI/oracles for objective dispute handling, blending speed and decentralization.
PredX: A multi-chain platform with Telegram mini-apps for AI-assisted predictions. Does on-chain executions and off-chain AI/data feeds, enhancing UX with social integration.

#4 Incentive Structures and Liquidity Models
Incentive structures are critical to prediction markets, as they drive user participation and ensure truthful reporting to produce accurate forecasts. These mechanisms align participant interests with market goals, rewarding accurate predictions and penalizing errors. This section classifies incentive structures into five categories: Market-Maker Model (Automated Market Makers), Order-Book Model, Token Staking, Scoring-Based, and Participation Rewards. Each leverages distinct motivators, liquidity provision, trading efficiency, reputation, algorithmic scoring, or activity-based incentives to encourage engagement.
1. Market-Maker Model (Automated Market Makers)
The Market-Maker Model uses Automated Market Makers (AMMs) to incentivize participation by enabling users to provide liquidity to prediction markets via smart contracts, typically on decentralized platforms. AMMs replace traditional order books with liquidity pools, where users deposit tokens (e.g., USDC, ETH) to fund trading for outcomes (e.g., “Yes” or “No” shares). The pool’s pricing algorithm, often a constant product formula (e.g., x⋅y = k), adjusts share prices based on supply and demand, ensuring continuous liquidity. Participants earn fees (e.g., 1-2% of trades) proportional to their pool contributions, incentivizing liquidity provision and accurate pricing. AMMs operate on-chain, with smart contracts handling deposits, trades, and payouts, ensuring trustless execution. The model encourages participation by rewarding liquidity providers while facilitating trading, though it requires high initial capital and can suffer from impermanent loss.
Mathematical Formula (AMM Pricing):
For a binary market with pools for “Yes” ( x )and “No” ( y ) outcomes, the constant product AMM maintains:
The price of a “Yes” share is:
Liquidity providers earn fees:
Code Example (Solidity for AMM Market):
// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;
contract AMMPredictionMarket {
uint256 public yesPool;
uint256 public noPool;
uint256 public constant K = 1000000; // Constant product
mapping(address => uint256) public liquidity;
function addLiquidity() public payable {
require(msg.value > 0, "No funds provided");
uint256 yesShare = msg.value / 2;
uint256 noShare = msg.value / 2;
yesPool += yesShare;
noPool += noShare;
liquidity[msg.sender] += msg.value;
}
function buyShares(bool _yes, uint256 _amount) public payable {
require(msg.value > 0, "No funds provided");
if (_yes) {
uint256 newYesPool = yesPool + _amount;
uint256 newNoPool = (K * yesPool * noPool) / newYesPool;
noPool = newNoPool;
yesPool = newYesPool;
} else {
uint256 newNoPool = noPool + _amount;
uint256 newYesPool = (K * yesPool * noPool) / newNoPool;
yesPool = newYesPool;
noPool = newNoPool;
}
}
function getPrice(bool _yes) public view returns (uint256) {
return _yes ? (noPool * 100) / (yesPool + noPool) : (yesPool * 100) / (yesPool + noPool);
}
}This contract implements an AMM for a binary market, adjusting prices based on pool balances.
Platform Examples

2. Order-Book Model
The Order-Book Model incentivizes participation through traditional exchange mechanics, where users place buy and sell orders for outcome shares ( say “Yes” at $0.60) on a centralized or decentralized order book. Orders are matched based on price and volume, with liquidity provided by user bids/asks or house-backed pools. Participants are motivated by potential profits from trading at favorable prices, akin to stock exchanges. Centralized platforms manage order books via servers, offering low-latency matching and fiat integration. Decentralized platforms use on-chain or hybrid order books, with settlements via smart contracts.

3. Token Staking
Token Staking incentivises participation by requiring users to lock tokens (e.g., governance or reputation tokens) to participate in markets or resolve outcomes, rewarding truthful reporting with token returns or additional rewards. In decentralised platforms, users stake tokens to place bets, vote on resolutions, or act as market creators, with stakes slashed for dishonest behaviour (e.g., incorrect votes). This aligns incentives with accuracy, as users risk losing tokens. Rewards may include governance rights, fees, or token appreciation. Staking is managed via smart contracts, with on-chain logic tracking stakes and payouts. The model fosters trust and engagement but requires token ecosystems and can be deterred by volatility.
Mathematical Formula (Staking Reward):
If incorrect, the stake is slashed:
Platform Examples
Gensyn Judge: Unveiled in 2025 on a custom chain, it uses AI and token staking for scalable prediction resolutions. Users stake $GEN tokens to vote on outcomes, earning governance rights and fees.
Polkamarkets: A prediction market on Polkadot, it uses POLK tokens for staking in event markets. Participants stake for trading and resolution and are rewarded with fees.
SWOT Analysis
Strengths:
Strong Alignment: Staking ties financial risk to accuracy, ensuring truthful reporting and resolution.
Decentralized Governance: Token holders influence market rules, enhancing community trust and engagement.
Flexible Rewards: Combines financial (fees) and non-financial (governance) incentives, appealing to diverse users.
Blockchain Security: On-chain staking ensures transparent, tamper-proof reward distribution.
Scalable Engagement: Token ecosystems support large-scale participation in DeFi markets.
Weaknesses:
Token Volatility: Fluctuating token prices (e.g., 2025 crypto dips) reduce reward predictability, deterring users.
High Entry Costs: Staking requires significant token holdings, excluding low-capital participants.
Complexity: Blockchain-based staking demands technical knowledge, limiting mainstream adoption.

Low Participation: Insufficient staking in niche markets weakens resolution accuracy.
4. Scoring-Based
Scoring-Based incentive structures reward users with points or leaderboard rankings based on prediction accuracy, often using algorithmic metrics like the Brier score. Participants submit forecasts (e.g., probability for an outcome), and scores are calculated post-resolution, with higher scores for accurate predictions. Points may translate to reputation, badges, or minor financial rewards in hybrid systems. Centralized platforms use databases to track scores, while decentralized ones use smart contracts. This model encourages skillful forecasting without direct financial risk, ideal for educational or community-driven platforms, but may lack strong incentives for high-stakes markets.
Mathematical Formula (Brier Score):
For ( N ) predictions, with forecast probability fi and outcome oi (1 or 0), the Brier score is:
Reward points are:
Platform Examples
Metaculus: A community-driven platform, prominent in 2025 for scalar and binary predictions (e.g., AI milestones), uses points and leaderboards to reward accuracy. Its scoring system incentivizes skillful forecasting, attracting thousands of users for non-financial engagement.
Good Judgment Open: A long-standing platform that awards points for accurate crowd-sourced predictions. Its leaderboard-driven model fosters competition, aligning with scoring-based incentives for educational purposes.

Conclusion
Prediction markets in 2025 stand at an inflection point, no longer niche experiments, but emerging as credible tools for information aggregation, hedging, and collective intelligence.
The future of prediction markets will likely be defined by three converging forces: scalability, interoperability, and institutionalization. Scalability is being addressed through high-throughput blockchains, Layer 2 rollups, and efficient off-chain order matching systems, enabling sub-second trades and mass-market accessibility.
Interoperability across chains, oracle systems, and even off-chain data streams will unify fragmented liquidity and unlock richer, more nuanced markets, including those covering complex real-world events.
Institutionalization is the final piece: as compliance-ready platforms emerge, expect hedge funds, insurers, and enterprises to integrate prediction markets into decision-making and risk management processes, driving liquidity toward the $10B+ mark by 2027.
Reaching this future requires three deliberate steps. First, continued investment in technical infrastructure: secure smart contracts, robust oracles, and resilient off-chain services must be prioritized to prevent exploits and downtime. Second, incentive design must evolve toward aligned, sustainable participation, reducing barriers for casual users while rewarding accuracy and liquidity provision. Third, collaboration with regulators and standards bodies is critical to legitimize the industry and create pathways for fiat and institutional adoption without diluting the decentralization ethos.
There is also an opportunity for innovation at the edges, integrating AI for market resolution, using zero-knowledge proofs for privacy-preserving participation, and building social-first prediction experiences (e.g., in chat apps or metaverse settings) to make forecasting as natural as tweeting. These are not speculative luxuries but necessary steps to bridge prediction markets from Web3-native communities to mainstream audiences.
In summary, prediction markets are on the cusp of becoming a core financial and informational primitive, much like spot exchanges and futures markets in prior decades. The next phase will favor platforms that strike the right balance between trustlessness, usability, and compliance, and that can scale without sacrificing market integrity. The winners of this transition will not just be platforms but societies, as we gain access to the most powerful crowd-sourced forecasting infrastructure humanity has ever built.
