Why do you always lose money on Polymarket?

Do you know why you can’t beat the front-runner on Polymarket? Because they scrutinize the rules like lawyers reviewing contracts, nitpicking every word.

In April 2026, a controversy on Polymarket about a Venezuelan leader exploded in the community.

On Polymarket, there was a market asking, “Who is the leader of Venezuela at the end of 2026?” Many traders’ instinct was: Maduro is in a U.S. prison, Delcy is running the cabinet in Caracas, and the actual power holder is obviously Delcy—so they bet on Delcy.

But the rules and supplementary explanations are written very clearly: “officially holds” refers to the person who has been formally appointed and sworn in. The UN-recognized Venezuelan government has not officially dismissed or replaced Maduro, and official government information still recognizes him as president. The rules also specifically add: “Temporary authorization to exercise presidential powers does not equal a transfer of the presidential office.”

Under this set of rules, even if Maduro is still in a U.S. prison, he remains the legitimate president of Venezuela.

There are many similar examples:

• After Polymarket issued stablecoins, the market had a dispute over “what is the Polymarket token FDV”: whether stablecoins count as tokens—a difference of a single word

• Iran uranium: the standard for “agreeing”—conditional statements vs. the formal signing of an agreement

Behind all these cases is the same logic: on Polymarket, rules are the core. But when the rules generate disputes, Polymarket has a complete adjudication process to resolve them. This article will introduce how this mechanism works, and where it is similar to traditional courts—and where there are fundamental differences.

1. Polymarket’s arbitration mechanism

Ambiguity in the text of the rules does not only cause pricing disagreements; it also becomes a formal dispute at settlement.

On Polymarket, many markets are settled every day, and markets involving political statements, diplomatic remarks, or military actions are especially prone to disputes.

Disputed events are actually the norm in prediction markets. Ambiguity creates pricing differences during the trading phase, then turns into dispute conflicts during the settlement phase—this is the same issue expressed at two different times.

To resolve these disputes, Polymarket has built a complete adjudication process. The settlement process has two paths: normal settlement and dispute resolution.

Step 1: Submit a Propose

When a market meets the settlement conditions, anyone can submit an arbitration outcome, declaring whether the market should be judged YES or NO. When submitting a proposal, the submitter must stake 750 USDC as a bond. This bond is the submitter’s endorsement of their own judgment. When there are no objections from the market, the user who submits the Propose can receive a reward of 5 USDC.

Currently, there are only 1782 users in the market who have submitted Propose. The highest-profit user has earned a total of $281K.

Step 2: 2-hour challenge window (Dispute)

After a proposal is submitted, it enters a 2-hour challenge period. This is the first branching point in the entire process.

If no one raises any objection within 2 hours, the system assumes the proposal is correct, the market settles directly, and the process ends. The vast majority of markets follow this path.

If someone believes the proposal result is wrong, they can challenge it within these 2 hours as well, and they also need to stake 750 USDC. If the challenge is successful, they can earn a bonus of 250 USDC.

Very few people specifically act as Dispute users. The user who earns the most in the Dispute stage is 0xB7A, with a profit amount of $17123 .

Step 3: Discussion period up to 48 hours

Once the dispute track is entered, both sides move into the UMA Discord discussion stage. The purpose of this stage is to allow each party to submit arguments and evidence: interpretations of the rule text, news reports, historical precedents, official statements—any materials that can support their position can be brought up in this stage.

The discussion period lasts up to 48 hours. This is the only stage in the entire process where reasons can be fully stated. The quality of this stage, to a large extent, determines the direction of the subsequent voting.

Step 4: 48-hour voting

After the discussion ends, UMA token holders enter the voting stage. Voting is divided into two phases, each lasting 24 hours.

• The first phase is blind voting. It requires each voter to make an independent judgment based on their own understanding of the rules, rather than following the big players.

• The second phase is public. If no vote is published during this phase, it is treated as an abstention, and the vote becomes invalid directly.

After the voting ends, UMA sets two settlement thresholds. Both must be met at the same time in order to complete the arbitration:

• In terms of participation level: at least 5 million tokens must participate in the vote to ensure the decision has sufficient representativeness.

• In terms of absolute consensus: the winning side’s vote share must exceed 65%, not just a simple majority above 51%.

If both thresholds are not met simultaneously, the vote fails, and it proceeds to the next round of re-voting, with up to 4 re-votes. After 4 rounds still without consensus, Polymarket’s official team has the right to directly intervene and make a ruling.

Step 5: Automatic settlement

Once the voting result is confirmed, the market settles automatically, and funds are distributed according to the result. There is no appeal, no re-examination, and no chance for remediation.

From the time the dispute challenge is submitted to the final settlement, the entire dispute process usually finishes within a week.

2. Polymarket vs. traditional courts: the same logic, different design

At first glance, Polymarket’s arbitration process is highly similar to traditional courts. Both have a party bringing a claim, a party challenging the claim, a discussion and statement stage, and finally an adjudicator who issues a result.

But the two systems differ fundamentally in one key design: separation of power.

1⃣ The court’s power is isolated

In traditional courts, plaintiffs and defendants only have the right to present their case; they do not have the power to decide. Judges only have the power to rule and hold no vested interest. More importantly, judges must remain independent from the case. Once there is any conflict of interest between a judge and the case, recusal must be enforced and another judge will be assigned to hear it.

The decision-maker and the interested parties are never the same people.

2⃣ Polymarket does not have this kind of isolation

UMA token holders are the arbitrators, but they can also hold positions in the disputed market at the same time. Which direction the arbitration goes directly affects their own profit and loss. The arbitrator and the interested party are the same person. In traditional courts, this is called a conflict of interest and would require mandatory recusal. But on Polymarket, it is legal and normal.

This design flaw is the root cause of the following two problems.

1. Why the discussion stage fails

In court, the positions of the plaintiff and defendant are fixed from the moment the lawsuit is filed. Lawyers do not switch sides mid-trial, nor withdraw their statements because the other side’s momentum is strong. The debate is built on this stability: clear stances and clear roles.

UMA Discord discussions face two problems at the same time.

Herd effect: Discussions are public and conducted under real names. Once an influential KOL takes a position, it becomes easy for others to follow along. Many participants only post a single “P1” or “P2” without giving any reasons.

Position shifts: People who participate in the discussion also hold positions in the dispute market. When their positions change, their stance naturally changes as well—this is why the phenomenon of posting an opinion and then deleting it is common on UMA Discord.

The root cause of both problems is the same: the arbitrators and interested parties are not isolated. Courts separate these two roles using a mandatory recusal system to ensure that stances remain stable during discussion. Polymarket does not have this isolation.

2. Why arbitration results are not transparent

In court, after judges hear complete statements from both sides, they make a judgment. The written judgment explains which side’s arguments were adopted, what the basis was, and why the decision is made this way. The losing party may be dissatisfied, but at least they know where they lost. Then, next time, they can reinforce their arguments in a targeted way.

These judgments form a precedent system that can be studied. Later judges, lawyers, and parties can cite them, so the standards for ruling become verifiable, learnable, and predictable.

After the UMA vote ends, there is only one result: YES or NO. The parties who discussed do not know what the voters looked at, what they believed, or why they leaned toward that side. They don’t know which arguments actually mattered, nor where the persuasiveness was insufficient. Because the arbitration logic is never made public, the outcome of disputes is difficult to learn from and accumulate.

Court judgments form a precedent system, while Polymarket’s arbitration leaves only a single result.

3. To conclude

So Polymarket is never merely a market for “guessing correctly about events.” It is more like a system that translates real-world events into legal text, and then translates that legal text into settlement outcomes.

Understanding the rules is as important as doing research. A frontrunner’s advantage often comes from a deeper understanding of the rules—knowing what this system acknowledges, and what the arbitration will recognize.

Whoever can realize earlier that there is a gap between “reality” and “rules” has a better chance to profit from the price deviations created by misinterpretation, disputes, and emotions.
