Could you build this?
No Operating a prime broker across prediction markets entails high-frequency algorithmic routing, margin/risk management engines, legal and regulatory compliance (CFTC/crypto cross-jurisdictions), and settlement custody.
What it would actually take: The stack needs high-throughput, low-latency market gateways connecting to both centralized order books (Kalshi via FIX/REST) and decentralized smart-contract order books (Polymarket on Polygon/EVM). The complex pieces are real-time cross-venue portfolio margin management, automated liquidation engines, and clearing/settlement custody infrastructure, accompanied by specialized financial regulatory frameworks. This requires financial software engineers, quant infrastructure architects, and compliance lawyers.
