Pricing mechanism
Opinion market: bettors wager on what the majority opinion will be on a question (subjective belief, not objective truth). Each market runs 24h; at close, trading halts and a gamified, points-based poll resolves it - the side with the most votes settles to $1, the losing side(s) to $0.
Settlement
Poll-based resolution by 'voters' (separate from bettors). Voters earn points for participation, which they can wager or redeem for cash; during public beta, sybil resistance relies on a proof-of-personhood protocol (one vote per verified user). Payouts on Solana.
Strengths
- Poll-based resolution of subjective opinion is a genuine differentiator vs two-token 'opinion launchpad' designs where market cap (whale/cabal capital) decides the winner
- Bettor + voter two-role design with proof-of-personhood sybil resistance aims for a credible measure of collective belief
- Broad, engagement-native topic range (politics, pop-culture, conspiracies, sports, breaking news); strong 'hyper-financialized social medium' narrative
- Ran a concrete $50K paper-trading Alpha (Dec 2025) with prizes + custom jewelry to seed early users
Weaknesses
- Resolution quality hinges on proof-of-personhood and honest voting - sybil/collusion resistance for subjective polls is hard and unproven at scale
- Subjective 'majority opinion' resolution is inherently contestable vs objective-event prediction markets
- Still early - the headline event was a paper-trading Alpha, not live real-money volume
- Payout automation still maturing (manual SOL transfers historically)
