[YichengYang-Ethan]

Adding Oracle3 to the Prediction Markets section.

Oracle3 is an open-source autonomous trading agent that operationalizes the Wang Transform pricing model across multiple prediction-market venues (Kalshi, Polymarket, Solana via DFlow). It complements the existing entries by providing a multi-venue execution agent with explicit constraint-based arbitrage and model-driven strategies.

The pricing engine is backed by a working paper: Pricing Prediction Markets: Risk Premiums, Incomplete Markets, and a Decomposition Framework (Yang, 2026, UIUC) — λ̂ = 0.183 estimated on 291,309 resolved contracts across 6 platforms.
