What Ravioli is
Ravioli is a free-to-play prediction market. You trade shares on real-world questions across sports, politics, and culture using free credits, and the price of a share is the crowd's live estimate that the outcome happens. Nothing here costs money, and the prizes are real.
A price is a probability
Every market trades between 0 and 100 cents a share. A share priced at 62c means the crowd puts the outcome at roughly 62 percent, and it moves as people trade. Read the number and you have the current consensus without wading through opinions.
Free credits, real prizes
You trade with Sense, the in-app currency. It is free, there is nothing to deposit, and it cannot be exchanged for cash. What you win is redeemable in the shop for gift cards and merch, so being right pays without anyone risking money.
How markets resolve
Sports markets settle against the official box score. Everything else resolves against cited sources, verified with live web search before payout. Winning shares pay 100 Sense each and settle straight into your balance.
Common questions
- Is any real money involved?
- No. There is no deposit, no wallet, and no crypto. Accounts start with free Sense and you can earn more through daily rewards and streaks. Sense never converts back to cash.
- How is this different from Kalshi or Polymarket?
- Same mechanics, none of the money. You get an order book, an automated market maker, and multi-outcome markets, but you play with free credits and compete for prizes instead of a payout in dollars.
- What are Debates?
- A second mode alongside the markets. You pick a side, write an argument, and AI scores the reasoning on fact-checking, relevance, and logic. Scores stay hidden until the debate resolves so nobody can copy a winning take.
Or see every open market, the debates, who is winning, or the full mechanics and scoring rules on the about page.
