As answered by people managing Twelve Data and Oddpool.
Oddpool's answer:
• Unified data-layer across many markets
Prediction markets—whether crypto-native or centralized—tend to be fragmented: different platforms, different UIs, different data formats. Oddpool cuts through that by aggregating live market data, odds, spreads, volumes, historical price data, and outcomes across many venues. Instead of hopping between dozens of sites or APIs, users get a single source of truth for cross-venue analysis.
• Real-time arbitrage & spread insights
Because Oddpool collects data across markets and displays it in a normalized, comparable format, it surfaces arbitrage opportunities, mispricings, and market-spread inefficiencies — something that’s extremely difficult to track manually when data is spread across multiple, independent platforms.
• Historical & analytic depth — not just surface-level odds
Oddpool isn’t just “current price = current probability.” It offers historical data, volatility tracking, trend analysis, volume & liquidity metrics, conviction changes over time, and more. That lets traders, researchers, or quant-style users go beyond “what does the price say now” to “how was price behaving over time, and what is implied by that.”
• Consolidated dashboard for decision-making
Instead of fragmented UIs and inconsistent metrics, Oddpool provides clean, normalized dashboards — helping users compare markets, track sentiment shifts, and analyze data side-by-side. That’s especially powerful in prediction-markets land where transparency is weak and data is siloed.
