When a market you bet on resolves, two things can happen: it pays you out (if you picked the winning side), or it doesn’t (if you didn’t). This guide walks through both - plus the case where you can claim a refund because the resolver never posted an outcome.

​
Wait for the market to be claimable

You can’t claim immediately when a market closes. The full sequence is:
  1. Betting closes when the close time hits.
  2. The resolver posts the outcome. Arcium decrypts every position (~10 seconds).
  3. The challenge window opens for 24–48 hours. Anyone can flag the result.
  4. The market becomes claimable once the window passes undisputed (or an admin resolves a dispute).
Only after step 4 can you claim. The app’s status badge tells you which phase the market is in - wait until it shows Claimable.

​
Claim a payout

If you bet on the winning side, your position is now claimable.

Open Positions

Go to the Positions tab. Find the resolved market in your list.Each card shows:
  • Your side and stake.
  • The market’s outcome.
  • Your projected payout.
2

Click Claim

A green Claim button is visible on positions where you won. Click it.Your wallet pops up with a single transaction to sign.

Wait for confirmation

A few seconds after you sign, USDC lands in your wallet. The position’s status flips to Claimed.
That’s it. There’s no manual approval, no off-chain step. The protocol already knows whether you won (Arcium decrypted your bet at settlement) and pays out the right amount automatically.
The amount you receive is calculated from the odds you locked in at bet time, adjusted slightly by the payout ratio at settlement. See Fees and odds.

​
You don’t need your decryption key to claim

This is the question that comes up the most, so it’s worth being explicit: Your local-storage secret is only needed to display your own side in the app. It’s not needed to claim. The protocol already knows whether you won - Arcium decrypted your position at settlement and wrote the outcome to the market account. Your claim just asks the program to pay out, and the program reads the outcome directly. So if you cleared your browser data and the Positions tab is showing your side as “encrypted,” you can still click Claim. The payout will go through.

​
Claim multiple positions

If you placed several bets on the same market - for example, three YES bets at different times - each one is a separate position. You claim each one independently. The Positions tab groups your bets by market, so you’ll see all three in one place. Click Claim on each. Each is a separate transaction.

​
Claim a refund

If a market enters the refundable phase, it means the resolver missed their deadline and never posted an outcome. The market never gets settled - instead, bettors can pull their net stake back. The flow:
  1. Open the Positions tab.
  2. Find a market in the Refundable phase.
  3. Click Claim refund.
  4. Sign the transaction.
USDC comes back to your wallet. The amount is your net stake (what entered the pool after fees) - not your original gross bet. The fees are not refunded.
There’s a refund deadline. If you don’t claim within the window after the market enters Refundable, the protocol admin can sweep the unclaimed funds. The app shows you the deadline on each refundable position. Claim promptly.

​
What happens if you don’t claim

Every claimable market has a claim deadline - usually a few days after the market enters Claimable. After that:
  • Your position is still recorded on chain, but the claim button stops working in the app.
  • Unclaimed payouts go to the protocol admin’s sweep, who uses them for accounting and treasury reconciliation.
In short: claim promptly. The app shows you the deadline; don’t ignore it.
