Common Risks and Security Measures in Prediction Markets

The trading essence of prediction markets is a contest over the probabilities of future events. Prices reflect what market participants expect, but this does not mean that prices equal the true probabilities. Factors such as market sentiment, information asymmetry, and insufficient liquidity can all cause prices to deviate from reality, leading to losses for you.

💡Common Risks:

1. Liquidity Risk: Prediction contracts for popular events usually have higher liquidity, and investors can buy or sell at any time. However, for some niche events, the trading volume of their contracts may be extremely low. When investors need to exit, they may not be able to find a counterparty in time, resulting in an inability to close positions or forcing them to execute trades only at unfavorable prices.

2. Information Asymmetry Risk: Institutional investors or insiders may have greater information advantages. Their trading activity can affect market prices, while ordinary investors are at a disadvantage in terms of information access and analytical ability, making them more likely to make incorrect decisions. For example, in April 2026, a U.S. servicemember was arrested after profiting $400,000 for placing bets on events related to Maduro on Polymarket—this incident exposed the risk of insider trading.

3. Ethical Controversy Risk

Betting on human tragedies such as wars and terrorist attacks puts participants under moral scrutiny. In 2026, under pressure, the platform removed the U.S. military rescue operation prediction section, reflecting the public backlash that such trades may trigger. If an individual’s trading record is made public, it is even more likely to have a negative impact on professional development.

👷How to Avoid Pitfalls?

‌1. Set up a fund firewall‌: Invest only funds that you can afford to lose completely. As a guideline, the amount for a single trade is recommended not to exceed 5% of your net assets.

2. Rational analysis—avoid blindly following the crowd: When engaging in prediction trading, decisions should be based on sufficient information and rational analysis, avoiding being swayed by market sentiment or other people’s views. Focus on the event’s fundamentals, analyze the various possible outcomes and their probabilities, rather than blindly following popular trades or believing rumors. At the same time, recognize that the price in a prediction market does not always reflect the true probability, and maintain independent thinking.

3. Avoid ethical minefields‌: Refuse contracts involving sensitive topics such as disasters affecting people’s livelihoods and violent conflicts.

4. Don’t blindly trust insider information: In the world, there is no wall that leaks nothing. The so-called insider information you receive may already be part of a “few hands” brokerage scheme.
