    Quick Summary

    The key takeaway from this page

    Winning contracts pay $1.00 per share. Your profit is $1 minus your purchase price, minus fees. Losing contracts pay $0. Partial exits are possible before settlement.

    How Prediction Market Payouts Work

    From market resolution to cash in your account — a plain-language guide.

    The Three-Stage Payout Lifecycle

    1

    Resolution

    The market closes. An oracle (NOAA data, AP election call, price feed, etc.) confirms the outcome. Winning contracts are identified automatically.

    2

    Settlement

    The platform calculates payouts. Winning contracts pay out at $1.00 face value. Fees are deducted: Kalshi up to 1.75¢/contract (entry only), Polymarket most markets fee-free (crypto up to 1.56%, select sports up to 0.44%), Robinhood $0.02/contract per side (both buy and sell).

    3

    Credit

    Funds move into your account balance. Timing varies by platform. On Coinbase-linked Kalshi accounts, a secondary sync step can add a display delay.

    Payout Timing by Platform

    Timing estimates below are sourced from official platform documentation. Settlement timing can vary by market category and oracle source — treat these as typical ranges, not guarantees.

    PlatformPayout MethodTypical Timing
    KalshiCash (USD)Most markets settle within a few hours after the outcome is known (often ~3 hours). Funds credit to your account balance immediately after settlement.
    PolymarketUSDC (crypto stablecoin)Uncontested resolutions: minimum 2 hours after the UMA oracle fires. Resolutions that are disputed and escalated to a UMA token holder vote can take significantly longer.
    RobinhoodCash (USD, brokerage)Up to 2 business days for proceeds to become available for withdrawal. Funds transfer from Robinhood Derivatives to your investing account, which may add a display delay.
    Coinbase (via Kalshi)Cash (USD)Two-step: Kalshi settles first, then Coinbase display syncs. Display lag is common.
    Money-state receipts

    Money-state receipt checklist

    A platform-neutral receipt model for users who think a prediction-market payout, balance, cashout, or settlement amount does not match what they expected. It separates trade fills, fees, open positions, settlement result, account credit, withdrawal state, and support evidence before implying funds are missing.

    A mismatch is not proof funds are missing. First identify which account state changed.
    Your expected payout, gross settlement value, cash balance, portfolio value, and withdrawable balance are different surfaces.
    Reconcile the records before assuming the platform failed to pay.
    1

    Trade fill ledger

    What did I actually buy or sell, at what price, and how many contracts filled?

    Expected payout math usually starts wrong when the user uses headline price instead of actual fills, partial fills, or average execution price.

    Evidence to collect

    trade history
    order confirmation
    filled quantity
    average fill price
    side bought/sold
    2

    Fee and spread ledger

    Which fees, broker fees, spreads, or slippage were applied before settlement?

    A winning contract can still produce a lower net result than the user expected if they ignore entry costs, wrapper fees, or execution spread.

    Evidence to collect

    fee line item
    trade preview
    platform fee page
    filled price versus displayed price
    3

    Open position and netting ledger

    Did I have offsetting positions, open orders, or losing legs that netted against wins?

    Users often compare one winning trade with account-level cash and miss open exposure, prior losses, reserved collateral, or partially offset positions.

    Evidence to collect

    open positions
    open orders
    reserved collateral
    account cash
    portfolio value
    4

    Settlement source ledger

    Which official source and rule actually resolved the market?

    Chart price, news headlines, screenshots, or late app graphs are not the settlement authority; the contract rule/source controls payout.

    Evidence to collect

    market rules URL
    official source URL
    resolution timestamp
    platform resolved state
    5

    Account credit ledger

    Where did the winning value land: cash balance, prediction balance, portfolio value, wallet, or withdrawal rail?

    Settlement, account credit, and external withdrawal are separate states; a user can be paid internally before the destination account reflects cash.

    Evidence to collect

    cash balance
    prediction-market balance
    wallet transaction
    withdrawal status
    timestamp/timezone
    6

    Support evidence packet

    If the records still do not reconcile, what proof should I send support?

    The product should reduce panic and improve support outcomes by turning vague complaints into a concise evidence packet.

    Evidence to collect

    market identifier
    order/trade IDs if visible
    screenshots
    timeline
    app/web surface
    timezone
    support ticket ID

    What are you seeing?

    I won, but my cash balance is lower than expected.

    Likely checks

    • fees/spread/slippage
    • open positions or offsetting losses
    • displaying portfolio value instead of cash
    • wrapper transfer delay

    Run trade-fill, fee, open-position, and account-credit receipts before saying a payout is missing.

    Compare payout-drop math

    The chart or app price looked different from the final settlement.

    Likely checks

    • chart lag
    • official source timing
    • final-minute average
    • rule wording such as exact-vs-at-least

    Run the settlement-source ledger and link to settlement-source explainers.

    Check settlement sources

    The platform says paid, but I cannot withdraw it yet.

    Likely checks

    • internal credit precedes withdrawal availability
    • banking-hour transfer cadence
    • wallet/network state
    • account restriction

    Separate account credit from external withdrawal and route to platform-specific troubleshooting.

    Separate credit from withdrawal

    Support evidence packet

    If the records still do not reconcile, send support a concise packet rather than a vague “not paid” ticket.

    market identifier
    order/trade IDs if visible
    screenshots
    timeline
    app/web surface
    timezone
    support ticket ID

    What this checklist does not claim

    • Do not claim a platform refused to pay unless official account records and support response verify that framing.
    • Do not promise a fixed payout, credit, or withdrawal timeline unless the official platform source states it for that exact product.
    • Do not hardcode fees, state availability, settlement timing, or platform regulatory status in page copy; use current official platform sources before publishing.
    • Do not cite forums, affiliate pages, or competitor guides as factual sources; they are demand signals only.

    How Resolution Triggers Your Payout

    Platform-specific gotchas: Settlement timing can vary with market category, oracle source, and account type. Coinbase-linked accounts have an extra display-sync step that can cause visible confusion before funds arrive. When in doubt, wait a few hours before contacting support — most display discrepancies resolve on their own. If your problem is not payout timing but an IBKR or ForecastEx tax document that seems disconnected from your net result, use this ForecastEx 1099 reconciliation explainer instead.

    A note on timing estimates

    Timing figures above are sourced from official platform documentation as of April 2026 (Kalshi Help Center, Polymarket official docs). These are typical ranges, not contractual SLAs — actual settlement can vary by market category and oracle source. Robinhood timing is from secondary sources pending an official Robinhood support page. When in doubt, wait a few hours before contacting support — most display discrepancies resolve on their own.
