How MercadoPrevio Works

Turn your predictions into opportunities. Simple, transparent, and exciting.

What is MercadoPrevio?

MercadoPrevio is a prediction market platform where you can participate in future events by buying contracts. If your prediction is correct, you win!

It's like investing in your opinion about what will happen in the world.

How it works in 4 steps

1

Choose an event

Browse through available markets and choose an event that interests you.

2

Make your prediction

Decide whether the answer is yes or no and buy contracts.

3

Wait for the result

Follow the event and wait until the closing date.

4

Receive your winnings

If you were right, each contract pays R$ 1.00. The platform retains 5% of the profit; the rest goes to your wallet.

Understanding prices

Contract price R$ 0.65

= 65% probability

The price reflects the market's probability that the event will happen.

Practical example

You invest: R$ 10.00
Contract price: R$ 0.40
Contracts purchased: 25 contracts
Profit (if correct): R$ 25.00
Fee (5% of profit): − R$ 1.25
You receive: R$ 23.75

Yes or No?

YES

You believe the event will happen by the closing date.

"Will Brazil win the World Cup?" → Buy YES if you think so!
VS

NO

You believe the event will not happen by the closing date.

"Will Brazil win the World Cup?" → Buy NO if you think not!
