What happens if I make this bet?

Set up a leveraged prediction-market bet. See your liquidation point, daily cost, best case, and worst case β€” in plain language.

1
What are you betting on?
This is the public price (think Polymarket / Kalshi). 50% means the market is split; 90% means most people think it'll happen.
2
How much money, and how big do you want to play?
This is the maximum you can lose. Even if everything goes wrong, you can't lose more than this.
Higher boost = bigger wins AND bigger risk. A 5Γ— boost means your $100 controls $500 of position size. 5Γ— the upside, 5Γ— the downside.
3
When does this question get answered?
Holding longer = pays more in daily fees. Holding right up to resolution is expensive β€” fees ramp up as the deadline approaches.
