OWN R&D · REAL-TIME TRADING

A goal is scored — and the order hits the exchange within a second.

Kalshi Arb — Our own system that detects goals in live football matches and trades on the Kalshi prediction exchange before the market reprices. Built for real money.

0.5–1 s REACTIONSK DETECTION + US EXECUTIONIOC ORDERS ON KALSHIREAL MONEY

CHALLENGE

On the Kalshi prediction exchange, football markets reprice within seconds of a goal. Whoever learns about the goal earlier and reacts faster still trades at the old price. What decides is the speed of the pipeline from detection to execution — and reliability, because the system works with real money.

SOLUTION

The detection side runs in Slovakia: through the Chrome DevTools protocol it intercepts WebSocket data of live matches directly from data feeds, recognises goal events in binary messages and filters duplicates (20-second debounce).

The signal travels over TCP to an execution server on a US VPS — close to the exchange for latency. It keeps markets pre-loaded and immediately sends an IOC limit order to Kalshi; acknowledgments and sell signals return over the same link. Documented reaction from goal to submitted order: 0.5–1 second.

Because real money is involved, the system has safeties: a per-match budget cap, three pricing modes by risk (live orderbook, fixed price, cached hybrid) and a dry-run mode for testing without trades. Every detection generates a dated report — operations are measurable and auditable after the fact.

RUNNING TODAY

Sub-second reaction From a goal in a live match to an exchange order in 0.5–1 s — automation where a human cannot keep up.

Two continents, one pipeline Detection in Slovakia, execution on a US server next to the exchange — an architecture designed around latency.

Deployed on live matches Dated detection reports from real matches — the system runs in production, not in a slide deck.

The same engineering for clients Realtime data, API integrations and automation that reacts for people — exactly what we build for companies.
