what's Vistadex?

Vistadex is a full-stack prediction market platform on Solana, operating as an aggregator and exchange. It matches equivalent markets across venues for complete event coverage, running real-time auctions to deliver optimal prices. Users trade binary outcomes (YES/NO) from one Solana account with best-in-class execution, leveraging Solana's speed for low-friction, efficient trading. A standout feature, Claim Markets, ingests public figures' X feeds and internet content via LLM extraction to identify verifiable forward-looking claims. These are matched to existing markets, with automated paper trades ($100 size at midpoint price from $10k virtual balance) to compute directional accuracy. PnL leaderboards rank performance objectively, filtering vague claims and using mark-to-market until resolution.

Vistadex rolled out claim markets, converting public claims into live prediction positions.
