How to Create a Crypto Prediction Market like Polymarket (Overview + Steps)

What Are Crypto Prediction Markets?

Crypto prediction markets are platforms where users bet on future events, from politics to crypto trends. These platforms utilize blockchain to enhance accuracy, security, and transparency, allowing users to wager on outcomes and potentially earn rewards if their predictions are correct. Traditional prediction markets often suffer from centralization and trust issues, but blockchain tech resolves this by decentralizing the process.

Key Advantages of Blockchain in Prediction Markets:

  • Transparency: All transactions are visible, fostering trust.

  • Smart Contracts: Automatic, tamper-proof payouts without intermediaries.

  • Data Accuracy: Oracles provide reliable real-world data, reducing manipulation risks.

Prediction Platforms Market Overview and Why Polymarket?

Prediction markets are witnessing an unprecedented surge in popularity, and crypto prediction market development is at the heart of this trend. In Q3 of the last year alone, the market exploded -- driven mainly by the anticipation surrounding the U.S. presidential election. These political events have a ripple effect, influencing everything from public sentiment to crypto regulations.

In the third quarter, prediction market activity skyrocketed, with betting volume rising by an astounding 565.4%. It jumped from $463.3 million in Q2 to $3.1 billion in Q3.

💡 Fun fact: Tech billionaire Elon Musk shared on his social media platform X that he thinks the cryptocurrency-based prediction platform Polymarket was a better way to predict the next U.S. presidential contest than traditional polling methods.

Why Polymarket Leads the Way

Among the many platforms out there, Polymarket stands out as the most significant player. With over a 99% market share as of September 2024, it's clear why founders are considering this platform as the gold standard in crypto prediction market development.

It's the decentralized nature, user-friendly design, and the use of oracles to ensure data accuracy that makes it the top choice. In the sections below we'll take a closer look at how Polymarket dominates the field.

Types of Prediction Markets on Polymarket

Crypto prediction markets come in all shapes and sizes, offering something for everyone. Below are some of the main categories you can explore in crypto prediction market development:

  • Crypto

  • Politics

  • Sports

  • Pop Culture

  • Mentions

  • Business

  • Science

Each prediction market type requires a reliable method to determine the outcome. That's where oracles come in.

💡 In crypto prediction market development, the variety of market types is endless -- everything from pop culture to scientific predictions can be integrated, attracting a wide user base and increasing engagement.

Each prediction has a deadline to find out whether it came true or not. A special oracle is responsible for determining the result of a prediction in Polymarket.

How Are Prediction Markets Created on Polymarket?

Creating a crypto prediction market involves clear steps to ensure transparency and accuracy. Polymarket follows a structured process with emphasis on quality:

Key Stages:

  • Market Creation: A new prediction with a set timeframe is created for users to bet on.

  • Asset Contribution: Users "vote" using assets, contributing to a prize pool.

  • Outcome Determination: Oracles verify the outcome, distributing rewards to accurate predictions.

Polymarket's Curated Approach:

  • Markets are created by Polymarket's team, guided by community suggestions.

  • Criteria include trading demand, social impact, credible information sources, and clear resolution timeframes.

How Are Prices Calculated on Polymarket?

On Polymarket, prices are driven by user demand and supply dynamics. Each outcome is tokenized as an ERC-1155 token, bought and sold with USDC. This creates a transparent, peer-to-peer betting environment.

Price Dynamics:

  • Initial Price: Set by early traders through market bids. For example, a $0.60 "Yes" bid and a $0.40 "No" bid set initial prices.

  • Live Trading: Prices fluctuate with user demand, reflecting real-time probabilities.

Example -- Polymarket

Let's discuss this example: "Will Ethereum reach a new all-time high in 2024?" There are two possible outcomes: Yes or No, and each is associated with ERC-1155 tokens representing these outcomes.

Initially, there's no set price for these tokens. The value of a "Yes" token will fluctuate based on market activity, starting at a neutral baseline. As we see on the screen, the current market price for a "Yes" token is $0.19. This means users believe there is a 19% chance that Ethereum will hit a new all-time high by the specified date. In other words, the token's price reflects the perceived probability of the event occurring.

💡Here's the opportunity: if you think the chances are actually higher, you can buy "Yes" tokens at this undervalued price. If Ethereum does indeed reach a new peak, each "Yes" token will pay out $1. This means your $0.19 investment would generate a profit of $0.81 per token -- a 426% return.

At the same time, any user who holds "No" tokens would lose their stake, as those tokens become worthless if the "Yes" outcome is true. However, Polymarket users aren't locked into their predictions -- they can sell their tokens whenever they want, cashing out early if they believe the market has shifted.

Detailed Tech Look at Polymarket's Outcome Tokens

Polymarket's technical structure is built on the foundation of crypto prediction market development, employing sophisticated mechanisms to ensure accuracy, transparency, and flexibility. One of the key components that make this possible is the Gnosis Conditional Token Framework (CTF), which underpins the prediction market's functionality.

Each prediction uses parameters:

  • Oracle: Verifies the event's final outcome.

  • QuestionId: Unique identifier from a hash of event details.

  • OutcomeSlotCount: Defines potential outcomes (typically binary).

Users receive conditional tokens tied to predictions, exchanging collateral (USDC). The oracle determines the outcome, rewarding those holding winning tokens.

Splitting & Merging

The Gnosis CTF contract allows the splitting and merging of prediction tokens, adding flexibility to the trading ecosystem. Here's how it works:

  • Splitting: Any user can split a unit of collateral (like USDC) into both binary outcome tokens (e.g., "Yes" and "No"). This means holding both tokens covers every possible outcome, balancing risk.

  • Merging: Users can also merge one of each binary outcome token back into a single unit of collateral. This keeps the total collateral consistent and prevents imbalances.

Splitting & Merging -- Polymarket

In a properly structured market, the combined value of these binary tokens always sums up the total collateral. For instance, if "Yes" is valued at $0.30, the "No" counterpart would be $0.70 -- both adding up to $1 of collateral.

Orders in Crypto Prediction Market Development

Polymarket utilizes a hybrid order book, combining off-chain efficiency with on-chain security. The Central Limit Order Book (CLOB) handles off-chain order matching, while on-chain execution maintains user control and transparency. Orders are EIP-712 signed data structures, stored off-chain until executed.

Limit Orders

Limit orders allow precise investments, executing trades only at a set price. Users specify their target price and quantity, with an optional expiration.

Market Orders

Market orders are immediate trades at the best current price, prioritizing execution over optimal pricing.

Liquidity Rewards Program in Crypto Prediction Market Development

Creating a robust, sustainable liquidity ecosystem is a cornerstone of effective crypto prediction market development. In Polymarket, liquidity is vital, and this is why they've introduced an engaging liquidity rewards program. The idea is simple: by posting resting limit orders, liquidity providers (also known as "makers") are automatically enrolled in Polymarket's incentive scheme. This program borrows heavily from the liquidity rewards strategy used by dYdX, but with tweaks specific to the binary nature of Polymarket's contracts.

Key goals of this rewards program include:

  • Encouraging liquidity across all stages of a market's life cycle.

  • Promoting tight quoting around a market's midpoint to ensure a healthy spread.

  • Incentivizing ongoing activity and reducing price manipulation attempts.

💡 For businesses exploring crypto prediction market development, setting up similar liquidity rewards can significantly enhance user engagement and market depth, key factors for long-term success.

Oracles in Crypto Prediction Market Development

In the realm of crypto prediction market development, oracles play a pivotal role by providing accurate, reliable data to determine the outcomes of events. For Polymarket, the oracle system is outsourced to a third-party service called UMA, a trusted player in the decentralized oracle ecosystem. Unlike traditional systems where data is sourced from a single, central authority, UMA provides a decentralized oracle that excels in providing verifiable data to the blockchain, making it a cornerstone of secure and transparent crypto prediction market development.

UMA's "optimistic" model assumes data is correct unless contested, using its Data Verification Mechanism (DVM) for disputes. UMA token holders handle challenges, preserving data integrity through community voting.

How UMA Works:

  1. A proposed market resolution has a 2-hour challenge period.

  2. If unchallenged, it's validated. Challenges trigger a 24-48 hour debate.

  3. UMA token holders vote on the outcome within 48 hours.

  4. Resolutions reward or penalize proposers and challengers based on accuracy.

UMA's system relies on game theory to discourage tampering. Participants face economic consequences for false data, promoting honest behavior. The commit/reveal voting method protects voter anonymity, reducing manipulation risks.
