Introduce

When you come across the terms “blockchain” and “marketplace” together, you might immediately think of the burgeoning ecosystem of exchanges that handle cryptocurrency transactions.

However, blockchain technology is extremely versatile and supports the creation of many types of markets, not just cryptocurrencies. This article will show how blockchain technology is completely transforming one specific type of market: prediction markets.

What is a prediction market?

Prediction markets are speculative platforms where participants trade the outcomes of future events instead of traditional financial assets. Participants buy and sell contracts that pay out based on the outcome of a specific event.

For example, consider a prediction market that asks, “Will the train from the US to Europe be running by 2035?” Traders can buy contracts betting on a “yes” or “no” outcome. If the train service starts before the deadline, the “yes” contract will be worth $1 and the “no” contract will be worthless, and vice versa.

The value of these contracts fluctuates as market sentiment and information changes. For example, if there are advances in underwater tunnel technology, the price of a "have" contract may increase.

Conversely, if such advances do not occur, the “no” contract is likely to increase in value. Prediction markets are effective forecasting tools because they aggregate diverse information and insights from a large number of participants, thus often yielding highly accurate predictions.

Prediction markets can cover a wide range of topics. These topics can include political elections, economic indicators, sporting events, and even weather forecasts. Essentially, any event with an uncertain outcome can be the subject of a prediction market. This flexibility allows prediction markets to tap into collective intelligence across a wide range of fields, providing valuable insights that may not be apparent from traditional analysis.

Why are prediction markets useful?

Prediction markets are efficient because participants are rewarded for acting on their knowledge and insights. Unlike traditional gambling, where luck plays a large role, prediction markets rely on participants' understanding of external factors that influence outcomes.

In the train example, if the “no” contract is trading at $0.90 and the “yes” contract is trading at $0.10, it indicates that the market has a shared belief that the train is unlikely to operate in 2035.

These markets are very good at aggregating and representing collective intelligence. They operate on the principle that the aggregate knowledge from a crowd is often more accurate than the knowledge of individual experts.

By analyzing prediction market data, stakeholders across many industries can gain valuable insights into future trends and probabilities. Some proponents even argue that prediction markets can foster a new form of democracy called futarchy, where policies are decided based on their predicted impact on the general welfare.

Prediction markets act as information aggregators. Participants with insider knowledge or expertise are economically incentivized to report their insights through trading. This results in market prices that reflect shared beliefs about the likelihood of an event occurring.

This feature can make prediction markets extremely useful for forecasting and decision-making. Businesses can use these insights to inform strategy, governments can gauge public sentiment about policies, and investors can identify emerging trends.

Prediction markets and blockchain technology

The value that prediction markets bring can be significantly enhanced by decentralizing them through blockchain technology. Traditional centralized platforms face limitations due to the need for users to trust the platform operator.

Blockchain-based prediction markets have many advantages:

Anti-censorship

Centralized prediction markets are vulnerable to being shut down or restricted. Decentralized platforms governed by smart contracts eliminate single points of failure. Every node on the network runs the same code, so there is virtually no single entity that can take down the platform.

Blockchain technology ensures that once deployed, prediction markets operate independently without the control of any single entity. This decentralization means that no single organization can easily censor or manipulate the market.

For example, in politically sensitive areas, traditional prediction markets may be shut down to prevent certain information from spreading. However, a decentralized prediction market running on a blockchain can resist such censorship, providing a more public and trustworthy platform for exchanging information.

Cut out the middleman

Blockchain technology eliminates the need for intermediaries by allowing users to interact directly with smart contracts. This reduces the costs and counterparty risks typically found in centralized platforms, as users do not need to trust a third party or pay additional fees.

Smart contracts automate the process of executing market transactions, ensuring agreements are executed exactly as intended. This automation reduces the risk of human error and fraud.

For example, in a traditional prediction market, participants may have to trust the platform operator to accurately settle bets and distribute payouts. In a blockchain-based market, smart contracts handle these tasks automatically, increasing transparency and trust in the system.

Increase accessibility

Decentralized prediction markets are permissionless markets that allow anyone in the world to participate. This opens up the opportunity for a more diverse and inclusive group of participants.

In traditional prediction markets, participants may face barriers such as high fees or limited accessibility due to location. However, blockchain-based markets welcome anyone with an internet connection.

This inclusivity not only democratizes access, but also enriches the market with more insights and perspectives. For example, someone in a remote part of the world with valuable local knowledge can contribute to a prediction market on a global platform, providing unique insights that might otherwise be overlooked.

The power of blockchain oracles

One challenge in decentralized prediction markets is determining the outcome of events without a central authority. Blockchain oracles solve this problem by providing a mechanism to verify actual outcomes. There are several ways to implement oracles:

  • Third-party data feeds: Simple but undermines decentralization because a third party controls the resulting data.

  • Reward for reporting: Users are rewarded for reporting honestly. For example, some prediction markets use a staking mechanism, where users stake tokens to report results. Honest reports are rewarded, while dishonest reports lose their staked tokens.

Blockchain oracles are essential to ensuring prediction market outcomes are accurate and trustless. Oracles act as a bridge between the blockchain and the real world, providing a reliable data feed. In a weather prediction market, an oracle can draw data from multiple trusted meteorological sources to verify outcomes.

Various oracle solutions are being developed to enhance the reliability and security of prediction markets. Some solutions use decentralized networks of reporters who verify data through consensus mechanisms. Others use a combination of decentralized verification and trusted data feeds. As blockchain technology matures, these oracles will become more sophisticated, ensuring that their results are more accurate and tamper-proof.

Future prospects and challenges

Despite its huge potential, blockchain-based prediction markets also face challenges. Scalability remains a key issue, as current blockchain networks can struggle with high transaction volumes.

Scalable blockchain solutions, such as rollups and other layer 2 technologies, can help alleviate these challenges and make prediction markets more efficient.

Regulatory uncertainty also poses a challenge. As prediction markets become more popular, they may attract increased scrutiny from regulators concerned about issues such as gambling laws and market manipulation. Clear and favorable regulatory frameworks can help ensure these markets develop in a way that maximizes their benefits while minimizing potential risks.

Another potential growth area is the integration of prediction markets with other blockchain-based applications. For example, decentralized finance (DeFi) platforms could integrate prediction markets to provide innovative financial products. Imagine a DeFi protocol where users can hedge against risks by participating in economic indicator prediction markets. Such integrations could create new opportunities and drive adoption of prediction markets across the broader blockchain ecosystem.

Summary

Prediction markets are not only fun tools for betting on future outcomes, but also sophisticated tools for aggregating reliable information across a wide range of fields. By rewarding individuals for sharing their knowledge, prediction markets can generate valuable insights into social trends, industry trends, and political trends.

The limitations of centralized platforms are being addressed by decentralized solutions powered by blockchain technology. As more advanced oracles are developed, these platforms will become more trustworthy and transparent, unlocking the true potential of the prediction market.

The combination of prediction markets and blockchain technology promises a future where collective intelligence is harnessed more efficiently, markets are more accessible and fair, and information flows more freely and securely.
