Could you build this?
Partial The front-end comparison tables and arb scanner UI are straightforward, but maintaining low-latency websocket connections across multiple prediction markets (Kalshi, Polymarket) to calculate real-time arbitrage before prices change requires solid data aggregation infrastructure.
What it would actually take: The architecture requires backend ingestion workers maintaining persistent WebSockets to Polymarket (order books/trades) and Kalshi's API, normalizing different contract specifications for the same underlying event. Redis is needed to maintain in-memory order books and compute cross-exchange spreads with fee adjustments in real time, serving updates to a Next.js/React frontend via server-sent events or websockets. The hardest parts are entity matching across platforms with differing resolution criteria and handling API rate limits/latency to ensure arbitrage alerts are timely.

Nobody's really built a analytics & bi tool for Legal yet.
