The Hidden Cost of Prediction Markets: The Internal Trading Dilemma in Decentralized Systems

Prediction markets have garnered attention for their decentralized nature, but as they scale, a growing issue has become evident—rampant insider trading. This is not an isolated case but a systemic dilemma.

In on-chain prediction markets, information flow is not as strictly regulated as in centralized exchanges. Participants with early access to information can easily arbitrage, while ordinary users remain unaware. This advantage is illegal in traditional finance, but in a decentralized ecosystem, it becomes the price of a "free market."

The problem is: to eliminate this phenomenon, regulatory and oversight mechanisms are needed, which directly contradict the original intent of decentralization. It’s a difficult trade-off—you cannot have both complete decentralized freedom and the market protections of traditional finance.

The future of prediction markets depends on whether the ecosystem can find a sustainable balance between these two extremes.

Basically, it's insider trading and exploiting the system, and you can't hide on the chain either. --- So decentralization just means big players can freely harvest profits... --- That's why I've always said prediction markets are just gambling with a different name. --- If I had known earlier, information asymmetry is always the biggest money secret. --- Once regulation comes, it’s no longer decentralized. What’s the point of playing? Better to just stick to trading profits early. --- Really, complete freedom and complete protection are fundamentally impossible to achieve at the same time. --- The systematic nesting doll in the crypto world is truly amazing.

Basically, it's just the legalization of cutting leeks; information asymmetry is always a powerful tool for making money.

Decentralization is a joke; information asymmetry cuts the leeks, whoever is faster makes money.

Same old story, decentralization just gets exploited --- Basically, information asymmetry is money asymmetry; whoever is faster makes the profit --- This is the true picture of Web3... freedom and fairness simply cannot coexist --- Once regulation comes, it’s no longer decentralization, this vicious cycle is unsolvable --- Prediction markets are now just a cash machine for big players, retail investors are just leeks --- Want safety and freedom? Dream on, that’s like having your cake and eating it too --- If I had known earlier, I wouldn’t have touched on-chain predictions; the information gap is terrifying --- Doesn’t this mean we’re all being arbitraged... sounds so uncomfortable --- In the end, decentralization still falls into the law of the jungle, sad --- Instead of waiting for a balance point, it’s better to learn how to identify insiders first

This is the trap of decentralization—freedom and fairness are mutually exclusive. Big players will always know first. What happened to the promise of equality for all? Once regulation comes, it’s no longer Web3. But if it doesn’t, you get slaughtered. Truly hopeless. Prediction markets are doomed to become playgrounds for information brokers. Instead of fussing over this, it’s better to secure your own wallet and stay honest.

It's the same old story again, called a free market in nice words, but actually just a playground for the big players. Information asymmetry equals wealth disparity; this is the same everywhere, and Web3 can't escape it. Decentralization? Ha, that depends on who has a higher degree of centralization. When regulations come, everyone behaves; if not, it's chaos—there's no third way. Prediction markets, at their core, still depend on who has better information; it's not a technical issue. Instead of obsessing over the balance point, it's better to face reality—big fish eat small fish. This is called the cost; if you want to enjoy freedom, you must accept the risk of being cut, and vice versa.

Isn't this the eternal contradiction of Web3—freedom and protection are fundamentally at odds? Information asymmetry will always be the king of arbitrage; on-chain transparency is overrated. Decentralization has become a paradise for insiders, which is quite ironic. Instead of struggling to find a balance, it's better to face reality: those who knew early make money, latecomers just take over. Regulation, when it comes, ends up destroying the ecosystem; if it doesn't, insiders run rampant. This game is doomed to have no winners. We're all just pawns in the prediction market.

Decentralization is like this: freedom and fairness are mutually exclusive. I've always said that prediction markets are information asymmetry games—whoever has better information makes more money. These days, wanting complete freedom without being exploited is just wishful thinking... Insider trading is indeed outrageous; on-chain, no one is regulating, and this is how it is. In my opinion, finding a balance is incredibly difficult; in the end, it's all about compromise. Regulation means losing freedom; no regulation means being exploited—either way, it's uncomfortable.
