CryptoStruct launches Kalshi and Polymarket real-time data feeds with Tokyo expansion
CryptoStruct launched a real-time WebSocket market data feed for Kalshi on Tuesday, covering full order books and all trades by UTC day. The same day, CryptoStruct expanded the feed to Polymarket and added a Tokyo endpoint on AWS ap-northeast-1, bringing both platforms' data to Asian infrastructure alongside Coinbase Spot. The offerings are self-serve and available now. CryptoStruct operates as a data infrastructure provider, not a trading venue.
Kalshi and Polymarket data now flows through the same pipe for the first time, cutting the engineering work for any app that wants to compare prices or hedge across both venues. Trading bots, analytics dashboards, and brokerage tools that previously maintained separate integrations can consolidate to one WebSocket connection.
The Tokyo endpoint matters because Asian market makers and quant funds have driven growing volume in crypto perpetuals; proximity lowers latency for any firm arbitraging between Kalshi's new US500 product and offshore equivalents. CryptoStruct is betting that regulated prediction markets need the same infrastructure standards crypto already demands. If the feed gains traction, it sets the template for how rival platforms become interchangeable backend commodities rather than sticky front-end brands.
CryptoStruct joins KashRock's prediction market API as the second infrastructure vendor this week normalizing data across Kalshi and Polymarket, turning rival platform feeds into a single integration target for trading apps.
