MANTIS

MANTIS is a Greek-first prediction-market product alpha. I built it to explore how localized markets could turn questions about politics, sport, and current affairs into clear forecasts.

Open the live demo

Project status: Prototype only. MANTIS does not operate a live or regulated prediction market, hold customer funds, or execute real-money trades. I paused the launch after reviewing the legal and operational requirements in Greece.

What I built

• Greek and English product flows
• Curated Greek and international markets
• Binary and multi-outcome market views
• Search, category, and liquidity-based discovery
• Market detail pages with probabilities and charts
• Trade-ticket and portfolio flows
• Responsive desktop and mobile layouts

The project took the idea from a market thesis to a working product alpha. I designed the path from market discovery to order entry and portfolio tracking, while testing how a prediction-market interface should work for Greek users.

Why I paused the launch

Once the alpha was working, I looked more closely at what a compliant launch would require in Greece. The legal structure and operational burden made the original plan impractical. I stopped before launch rather than operate with unresolved risks.
