Do you know why it's hard to compete with the front-runner in Polymarket? Because they focus on the rules, dissecting them like lawyers reviewing contracts.

In April 2026, a controversy about the leader of Venezuela erupted in the community on Polymarket.

There is a market on Polymarket asking, "Who will be the leader of Venezuela by the end of 2026?" Many traders' intuition was that: Maduro is in a U.S. prison, Delcy is presiding over the cabinet in Caracas, and the actual power holder is obviously Delcy, so they placed their bets on Delcy.

But the rules and supplementary notes are very clear: "officially holds" refers to the person who is formally appointed and sworn in. The Venezuelan government recognized by the UN has not formally removed or replaced Maduro, and official government information still designates him as president. The rules also specifically add: "Temporary authorization to exercise presidential powers does not equate to the transfer of the presidential position."

According to 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, a controversy arose about "What is the FDV of Polymarket tokens": Are stablecoins considered tokens, a matter of a single word difference?
• Iranian uranium: The standard for "agreement," conditional statements vs. formally signed agreements

The underlying logic in these cases is the same: in Polymarket, the rules are central. However, when rules lead to disputes, Polymarket has a complete adjudication process to resolve them: this article will introduce how this mechanism operates and how it compares to traditional courts in terms of similarities and fundamental differences.

1. Polymarket's Adjudication Mechanism

The ambiguity of rule texts not only causes pricing discrepancies but can also lead to formal disputes during settlement.

Every day, a substantial number of markets settle on Polymarket, especially those involving political statements, diplomatic remarks, and military actions, which are particularly prone to disputes.

Disputed events are actually the norm in prediction markets. Ambiguity creates pricing discrepancies during the trading phase and turns into conflict during the settlement phase—this reflects the same issue at different points in time.

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

Step 1: Submit a Proposal

When a market meets the settlement conditions, anyone can submit a ruling result, declaring whether the market should be judged YES or NO. A deposit of 750 USDC is required when submitting a proposal as collateral, which serves as an endorsement of the submitter's judgment; when there are no objections, the user who submitted the proposal can receive a reward of 5 USDC.

Currently, only 1782 users have submitted proposals in the market, with the highest-earning user having earned a total of $281K.

Step 2: 2-Hour Challenge Window (Dispute)

After a proposal is submitted, a 2-hour challenge period begins. This is the first fork in the entire process.

If no one raises an objection within 2 hours, the system defaults the proposal as correct, and the market settles directly, ending the process. The vast majority of markets follow this path.

If someone believes the proposal result is incorrect, they can raise a challenge within this 2-hour window, which also requires a deposit of 750 USDC. A successful challenge can earn a bonus of 250 USDC.

Very few users specialize in Dispute; the user who earns the most in the Dispute phase has the username 0xB7A, with a profit amount of $17123.

Step 3: Up to 48-Hour Discussion Period

Once on the dispute track, both parties enter the UMA Discord discussion stage. The purpose of this phase is to allow each side to present arguments and evidence: interpretations of rule texts, relevant news reports, historical precedents, official statements—any material that can support their position can be introduced in this phase.

The discussion period lasts up to 48 hours and is the only phase where parties can fully state their reasons; the quality of this stage largely determines the direction of subsequent voting.

Step 4: 48-Hour Voting

After the discussion ends, it enters the voting phase for UMA token holders, which divides into two stages of 24 hours each.

• The first stage is blind voting. Each voter must make an independent judgment based on their understanding of the rules, rather than follow the lead of large players.
• The second stage is public voting. Votes that are not disclosed in this stage are considered abstentions, and the ballots are rendered invalid.

After voting concludes, UMA has established two settlement thresholds that must be met simultaneously to complete the ruling:

• In terms of participation volume: at least 5 million tokens must participate in voting to ensure that the ruling has sufficient representativeness.
• In terms of absolute consensus: the winning side's voting rate must exceed 65%, rather than simply a majority of 51%.

If both thresholds are not met, the vote fails, leading to a resubmission for another round, with a maximum of 4 resubmissions. If there is still no consensus after 4 rounds, Polymarket officials have the authority to intervene directly in adjudication.

Step 5: Automatic Settlement

Once the voting results are confirmed, the market automatically settles, distributing funds according to the result. There are no appeals, no retrials, and no chances for remedy.

The entire dispute process, from challenge submission to final settlement, usually completes within a week.

2. Polymarket vs. Traditional Courts: The Same Logic, Different Designs

On the surface, Polymarket's adjudication process is highly similar to that of traditional courts: there are parties making claims, parties challenging claims, a discussion phase, and ultimately a decision maker giving the outcome.

However, the two systems fundamentally differ in one design aspect: separation of powers.

1⃣ The powers of the court are isolated

In traditional courts, the plaintiff and defendant have speaking rights but no ruling rights. Judges have ruling authority but no vested interest. More importantly, judges must maintain independence from cases. Once a judge has any interest linked to a case, they must be recused, and another judge must be assigned.

The adjudicator and the interested parties are never the same person.

2⃣ Polymarket lacks this separation

UMA token holders are the decision-makers, but they can simultaneously hold positions in the dispute markets. Which way they rule directly impacts their profits and losses. The adjudicators and the interested parties are the same people, which in traditional courts is considered a conflict of interest and must be avoided, but in Polymarket, it is legal and normal.

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

1️⃣ Why does the discussion phase fail?

In court, the positions of the plaintiff and defendant are fixed from the moment of the lawsuit. Lawyers do not suddenly switch sides in the middle of a trial, nor do they withdraw their statements due to the opponent's strong momentum. Clear positions and distinct roles create stability, which the entire debate is built on.

The UMA Discord discussion faces two issues simultaneously.

Herd mentality: Discussions are held publicly under real names; once an influential KOL expresses a stance, it easily turns into mere following afterward. Many participants just post a simple "P1" or "P2," without providing any reasons.

Position shifts: Participants in the discussion may also hold positions in the dispute markets; when their positions change, their stances naturally shift. This is why we often see comments made in UMA Discord being deleted after posting.

Both issues stem from the same root: the lack of separation between adjudicators and interested parties. Courts use mandatory recusal systems to separate these two roles, ensuring stability in positions during discussions; Polymarket does not have this separation.

2️⃣ Why are adjudication results not transparent?

In court, after listening to complete statements from both sides, the judge makes a ruling, specifying which arguments were accepted, the basis of the decision, and the reasoning behind the ruling in the judgment document. The losing side may be dissatisfied, but at least they know where they lost and can strengthen their arguments accordingly next time.

These rulings form a system of precedents that can be studied, allowing subsequent judges, lawyers, and parties to reference them, making ruling standards discoverable, learnable, and predictable.

After UMA voting ends, there is only one result: YES or NO. The parties involved in the discussion do not know what voters saw, what they believed, or why they leaned toward one side. The winning side does not know which argument had an impact, and the losing side does not know where the persuasiveness fell short. Because the logic governing the adjudication is never disclosed, the outcomes of disputes are difficult to study and accumulate.

The court's judgment forms a precedent system, while Polymarket's adjudications leave behind only one result.

3. Final Thoughts

Therefore, Polymarket has never been merely a market for "guessing the outcome of events"; it is more like a system that translates real events into legal text and then translates legal text into settlement results.

Understanding the rules is as important as conducting research. The advantages of the front-runner often come from a deep understanding of the rules, knowing what this system recognizes and how decisions will be made.

Whoever can recognize the gaps between "reality" and "rules" earlier has a better chance of profiting from the price distortions created by misunderstandings, disputes, and emotions.
