You open the Polymarket page and notice that a position you had yesterday is gone today. Your first reaction may be "the market settled," but it could also be that the frontend data just did not load. These two situations require completely different responses. Stay calm and check before acting.

Key Point: Check the Status First, Then Decide If It Is "Settled" or "Not Displayed"
There are two completely different reasons a position may disappear:
Case A: The market has settled
The event result is already out, and your position was converted into USDC, so it naturally disappeared from your holdings list. This is the normal process.
Case B: Frontend data delay
The market has not settled yet, but the page temporarily failed to load your position data due to caching, network, or API sync issues. Your position is still on-chain, it is just not being displayed.
The key to telling these two cases apart is to look at the market status, not at the holdings list.
Step 1: Check the Market Status First
[What to do]: Confirm what stage the market is currently in: "settled" or "not settled."
[How to do it]:
Open the market's detail page, not your holdings page.
Check the status label at the top of the page or in the rules area.
Case A: The status shows "Resolved" or "已解决"
This means the market has completed settlement, and your position has indeed become USDC.
[What to do]: Go to the "Portfolio" or "Balance" page and check whether your USDC balance increased. If it did, your position was automatically converted into money, and you just did not notice.
[Completion standard]: You see the corresponding amount of USDC added on the balance page.
Case B: The status still shows "Open" or "待定"
This means the market has not settled yet, and your position should still exist in theory.
[What to do]: It may be a frontend display issue. Go to the "Profile" page and look at the address link directly. This usually lets you bypass frontend caching and see the real data.
[Completion standard]: You confirm through the address link that the position still exists, and it is just not shown on the page.
Step 2: If the Status Is Still "Open" but the Position Is Missing, Check for Frontend Delay
[What to do]: Confirm that it is a frontend caching or sync issue, not that your position is actually gone.
[How to do it]:
Refresh the page: This is the simplest and most effective method. Polymarket position data relies on WebSocket push updates, and sometimes there can be push delays. A hard refresh, Ctrl+F5 or Cmd+Shift+R, usually fixes it.
Clear browser cache: If refreshing does not work, clear localStorage or site cache and reload the page.
Check the Profile link: Go directly to polymarket.com/profile/your-wallet-address to bypass frontend caching and read on-chain data directly. If you can see the position there, the position still exists and the problem is on the frontend.
Try another browser or device: If none of the above works, try a different browser or mobile device to rule out local environment issues.
[Completion standard]: The position reappears in your holdings list, or you confirm through the Profile link that the position exists.
Common Causes: Why Does a Position "Disappear"?
Reason 1: The market settlement process is not complete
Some markets do not make positions disappear immediately even when the result shows "Resolved." In Polymarket V2, the settlement process relies on on-chain operations, and there may be brief "ghost trades" or settlement delays. If your position shows as filled but the on-chain transaction actually failed, the frontend may show the position first and then withdraw it later.
Reason 2: Polymarket infrastructure pressure
Polymarket's recent growth has far exceeded its infrastructure capacity. The official VP of engineering admitted that the team was not prepared to scale. Price delays, order cancellations, and slow trade confirmations are currently known issues. A position suddenly disappearing is sometimes a display anomaly caused by infrastructure pressure.
Reason 3: Browser local storage problems
The Polymarket frontend relies on localStorage to cache trade status. If local storage is corrupted or expired, position data may load incompletely.

Troubleshooting Checklist
| Symptom | Possible Cause | What to Do |
|---|---|---|
| Position disappeared, market status "Resolved" | Market settled, position already converted to USDC | Check the balance page to see if USDC increased |
| Position disappeared, market status "Open" | Frontend cache or API sync delay | Refresh, clear cache, check Profile link |
| Position appeared, then disappeared after refresh | Ghost trade, on-chain settlement failed | Check transaction hash status on Polygonscan |
| All positions disappeared | Wrong wallet address selected | Check the currently selected address in MetaMask |
Risk reminder: Do not place a new order just because "the position disappeared." If the position is actually still there but just not displayed, you may open a duplicate position and tie up unnecessary funds. Confirm the on-chain status first before acting.
