# Multiplier Predictions

Strike Multiplier Predictions is a fixed-multiplier, exact-result prediction product. The 2026 World Cup is the first event series and use case.

The live app is available at [strike.fun/world-cup-multiplier-predictions](https://strike.fun/world-cup-multiplier-predictions).

For protocol, economics, coverage, settlement, API, and vault details, see [Multiplier Predictions Protocol](/protocol/world-cup-multiplier-predictions.md).

## What it is

Each event lists one or more clearly defined outcomes, such as exact match result fields for the first World Cup event series. Every selectable outcome has a fixed multiplier.

A prediction wins only if **every selected outcome is correct**. If any selected outcome is wrong, the multiplier prediction does not win.

## Quick example

* Outcome A: 5x
* Outcome B: 10x
* Combined multiplier: 50x
* Prediction amount: 10 USDT
* Potential payout if both selected outcomes are correct: 500 USDT

The app shows the combined multiplier and potential payout before you submit. The final accepted amount depends on the quote and vault checks.

## Submit a prediction

1. Open [strike.fun/world-cup-multiplier-predictions](https://strike.fun/world-cup-multiplier-predictions).
2. Choose an active multiplier event.
3. Select one or more outcomes.
4. Review the combined multiplier and potential payout.
5. Enter your prediction amount in USDT.
6. Confirm the wallet flow: USDT approval if needed, then vault submission.
7. Check your portfolio receipt for status, selected outcomes, prediction amount, potential payout or refund, and transaction links.

## Earn and Bonus Backstop

The Earn tab lets users contribute USDT to the Bonus Backstop Pool.

Contributors may earn when the Prediction Pool has leftover funds after settlement. The Bonus Backstop Pool can also be used to cover accepted prediction payouts when the Prediction Pool is not enough, so contributions carry downside risk.

Review the app’s pool, coverage, and risk information before contributing. For the full economics, see [Multiplier Predictions Protocol](/protocol/world-cup-multiplier-predictions.md).

## Claim or refund

After an event is settled:

* Winning predictions can claim their eligible payout.
* Cancelled or refunded events can expose refund actions.
* Portfolio receipts show claim or refund actions when they are available.

If a claim or refund is not shown, the event may still be open, settlement may not be finalized, or the connected wallet may not have an eligible receipt.

## Important notes

* A multiplier prediction is final once submitted.
* Exact-result rules matter: every selected outcome must be correct to win.
* Bonus Backstop Pool contributors can earn rewards but also carry backstop risk.
* Always review the event, selected outcomes, combined multiplier, prediction amount, potential payout, and wallet prompts before confirming.
