Funding a trading account moves money into a separate service with its own deposit, trading and withdrawal conditions. PredictPedia does not accept deposits or hold trading balances. Use the trading platform's authenticated funding screen, and read the instructions again for each transfer.
Record the exact destination
Polymarket's deposit instructions require selecting both the token and network, then using the address shown for the account. Addresses can differ across networks.[1] Its international documentation describes pUSD as the trading collateral token backed by USDC on Polygon.[2] This does not mean every external token or blockchain is an accepted deposit route.
Before sending crypto, compare the selected network, asset, recipient address and minimum deposit with the withdrawal form at the sending service. Start with a small amount that still meets the displayed minimum. Record the transaction hash. A familiar ticker alone does not prove that two tokens or networks are compatible.
Separate buying power from withdrawable cash
Kalshi's bank-deposit documentation distinguishes deposit processing from funds credited for trading.[3] Being able to buy a contract does not establish that the deposit is fully settled or immediately withdrawable. Review any hold before placing a trade whose proceeds you will need soon.
| Balance or status | What to verify |
|---|---|
| Deposit submitted | Whether the payment actually left the source account |
| Trading balance | Whether provisional credit is included |
| Open positions | How much cash remains tied to contracts |
| Withdrawable amount | Holds, minimums, verification and destination restrictions |
Budget the entire transfer
Use the fees displayed by both the sending service and the receiving platform. Kalshi publishes a fee schedule; the applicable charge can depend on the funding method.[4] Network charges and third-party conversion costs can be separate from a trading fee.
In a hypothetical transfer, sending $100 with a $2 sending charge leaves $98 before any other costs. If your plan requires $100 of trading capital, the transfer amount and available balance are different quantities. Keep enough uncommitted cash for the fees you can identify instead of assuming the headline deposit becomes the exact trading balance.
Test the return path
After the initial deposit settles, inspect the withdrawal workflow. Confirm that you control the destination and can satisfy any account verification requirement. Selling a position, resolving an event and withdrawing cash are separate steps; an open order or an unsettled position is not cash ready to leave the platform.
If a transfer is missing, gather its timestamp, amount, network and transaction or payment reference before contacting official support. Never send a wallet recovery phrase or private key to a support account. Do not resend the full amount merely because the first transfer is delayed; first reconcile its status with the receiving service.
