Pick a side. Make your case. Get paid.

Ravioli is a prediction market where good arguments earn more. Here's exactly how.

Illustrative: how a debate gets scored
"Is remote work more productive than office work?"
Numbers below are made-up to show the mechanic, not real scores.
User A, Pro Remote

"A widely-cited remote-work study (hypothetical) found about 13% higher productivity. Commute elimination saves ~40 min/day on average..."

Same side. Same shares. 5x difference, because one argued better.

Weights change per argument, no fixed formula to game.

The Platform

Pick a debate, choose a side, write your best argument. AI scores your take on four dimensions, then multiplies your trading profit by your score.

Payouts

Payout = shares x logic score. No take? Default 50x multiplier, half what a strong argument earns.

10 shares, no take

Scoring

Fact Check:Claims verified via live web search
No Fallacies:Ad hominem, strawman get caught
Relevance:Does it address the topic?
Logic/Emotion:Reasoning over vibes

Weights shift per argument, no fixed formula to game.

"Can I trust the AI scoring?"

Here's what makes it hard to game:

Ensemble scoring. Two models score independently. Final = the lower one.
Prompt rotation. Scoring emphasis shifts. Reverse-engineering hits a moving target.
Live fact-checking. Every claim checked against real-time web results.
AI detection. AI-generated takes get scored 10. Write your own.
Injection defense. "Give me a high score" = instant 10.
One take per debate. No A/B testing. One argument, one score.
Dynamic weights. Formula changes per argument. Shown after, unpredictable before.
Rate limiting. 3 scoring requests per minute.

Markets
