Pricing mechanism
Capital-backed opportunity markets (information finance): a creator sets a prize pool and a question; participants add options and stake (encrypted/confidential) on the ones they believe in. All committed capital is returned (no downside); the creator picks up to 10 winning options and the prize pool is split among their backers by a score of stake amount x time-in-market x earliness.
Settlement
Creator selects winning option(s) and prize-pool split; backers' encrypted choices are revealed and rewards distributed by score (stake/time/earliness). All stake returned (no-loss). Confidential staking via Arcium MPC on Solana. Explicitly NOT futarchy - the thesis is information access, not correcting human judgment.
Strengths
- First production implementation of the Paradigm Opportunity Markets primitive (Dave White and Matt Liston, August 2025)
- Arcium MPC integration solves the public-goods leak that has historically killed sponsor-funded prediction markets
- Concrete use cases shipping: Colosseum hackathon market, Hiring Market with SolRouterAI
- Won Arcium grand prize at Solana Privacy Hack (February 2026); active Solana presence with @colosseum endorsement
- Open-source code on GitHub; docs portal live; engineering credibility
Weaknesses
- Single-chain (Solana only) limits cross-platform composability with EVM ecosystems
- Opportunity Markets are a new primitive; sponsor-side education burden is high
- Small team, no disclosed institutional funding round yet (post-launch)
- Confidential pricing depends on Arcium MPC availability and finality
