Ravioli, Prediction Markets & Debates
Science Markets
This market resolves to Yes if NASA publicly announces a new application of its GeoCryoAI framework, beyond mapping zero-curtain conditions, by February 1, 2027.
This market resolves to Yes if, by March 31, 2027, a peer-reviewed scientific study confirms that energy in turbulence can transfer from small to large scales (backward energy cascade), reversing the traditional forward cascade model, as demonstrated by computer simulations at KTH Royal Institute of Technology. Confirmation must be published in a reputable scientific journal.
Will researchers discover a commercially viable alternative to platinum for hydrogen fuel production by June 30, 2027?
Will the AI-discovered natural molecule receive FDA approval by July 2027?
Will the new spectrometer detect a novel solar phenomenon during the next solar eclipse?
Will a commercial application of sunlight-induced quantum entanglement be announced by August 1, 2027?
This market resolves to Yes if, by August 13, 2027, the hypothesis that black holes older than the Big Bang explain dark matter is widely accepted by the scientific community, as reflected in recognized scientific consensus publications and statements by major scientific organizations.
This market resolves to Yes if a commercial product using nanocrystals synthesized through the new method described by University of Chicago researchers is publicly announced by any company by December 31, 2027.
This market resolves to Yes if a scientific demonstration of a practical quantum technology application using entanglement created by sunlight is publicly announced by December 31, 2027. Practical applications may include quantum communication or computing tasks. The announcement must come from a credible scientific organization or journal.

Will definitive evidence for black holes predating the Big Bang be found by the end of 2027?
This market resolves to Yes if any AI-designed intrabodies are used in clinical trials for Alzheimer's, Parkinson's, or Motor Neurone Disease by December 31, 2027. To confirm resolution, announcements from reputable research institutions or clinical trial registries will be used.
Will the concept of 'disruptive science' undergo a significant revision in a major scientific journal by December 2027?
Will a working quantum compass prototype using phonon lasers be demonstrated by the end of 2027?
Will an electron 'catapult' find commercial application in solar cells by 2027?
Will the TOFA compound enter human clinical trials for obesity treatment by December 31, 2027?
This market resolves to Yes if an official report states that the global average temperature has reached or exceeded 1.5°C above pre-industrial levels by December 31, 2027. This is based on data from leading climate monitoring organizations such as NASA, NOAA, or the IPCC.
Will the NSF's new Ph.D. model be considered successful by August 1, 2028?
Will chickpeas be successfully grown on the Moon by the end of 2028?
Will a successful chickpea harvest be achieved in lunar soil simulant on the Moon by 2028?
This market resolves to Yes if a verifiable source confirms the successful establishment and operational status of a nuclear power station on the Moon by the end of 2036. The source must be from a reputable space agency such as NASA or an equivalent international organization.
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.
