# How to Dispute a Market Outcome

Disputes keep BigMarket fair and transparent.\
If you believe a market’s resolution was wrong or data was inaccurate, you can raise a dispute — directly from the market page or by calling the smart contract.

***

### Who Can Dispute

Anyone who **has a stake in the market** can open a dispute.\
There’s **no slashing risk**, but you must have participated — this prevents spam and ensures only genuine participants can challenge outcomes.

***

### How to Dispute

1. **Wait for the market to enter the “Resolving” state.**\
   Once the initial outcome is posted (via oracle or resolution agent), the “Dispute” option becomes available.
2. **Visit the market page** on **bigmarket.ai** and click **“Dispute Outcome.”**\
   You can also call the contract directly if you prefer to interact on-chain.
3. **Confirm your dispute.**\
   This signals that you disagree with the reported outcome and triggers a **voting window**.

***

### The Voting Window

* The **dispute voting period lasts 2 days** (48 hours).
* During this time, DAO participants can vote to confirm or overturn the outcome.
* The voting duration can be updated later by DAO proposal.

When the vote concludes, the result is finalized **on-chain**:

* If the vote **upholds** the dispute → the market outcome changes.
* If the vote **fails** (no or low participation) → the market **resolves to the original outcome**.

***

### Dispute Lifecycle (Visual)

Here’s how the process works from resolution to final claim:

```
[ Resolving ]
   ↓
[ Disputed? ] — No → [ Resolved / Claims Open ]
        ↓ Yes
[ Dispute Voting Window (2 days) ]
        ↓
[ Voting Outcome Finalized On-Chain ]
        ↓
[ Resolved / Claims Open → Claim Your Rewards ✅ ]
```

***

### 💡 Key Takeaways

* Anyone with a stake can dispute.
* No slashing or penalties for disputing.
* Voting lasts 2 days and can be changed by DAO vote.
* If no votes are cast, the market **defaults to the original resolution**.

This keeps the system open to correction without adding unnecessary risk or complexity.
