Triangular Arbitrage Calculator Excel for KALSHI Markets

triangular arbitrage calculator excel is a search phrase that shows people want a practical tool for Kalshi binary markets. In Kalshi terms, each contract has a YES and a NO side, and the fair value typically sums to one dollar. This article explains how to think about triangular arbitrage on Kalshi and how an Excel workflow can help you spot edge opportunities without promising guaranteed profits. You’ll see how to frame inputs, monitor the best-ask prices for YES and NO, and translate those signals into actionable decisions within KalshiArb’s non custodial workflow.

Understanding triangular arbitrage on Kalshi binaries

On Kalshi every market is a binary YES/NO contract with a price between 0.01 and 0.99. Triangular arbitrage in this context means finding a price triangle where the best asks on YES and on NO are sufficiently cheap that buying both sides yields a small, risk-defined edge when the sum dips below 1.00. The key is that the edge is defined by the gap between the combined asks and the settlement dollar, not by any external oracle. In practice you look for moments when bestAsk(YES) + bestAsk(NO) is under 1.00, then you buy both legs to lock in edge minus the per contract fee.

How to adapt an Excel-based calculator for Kalshi edge

An Excel workflow starts with pulling live or near real time quotes for YES and NO from Kalshi’s REST API. You translate those quotes into a two-column price grid and compute the spread against 1.00. The goal is to flag when the sum of the two prices is below 1.00 to trigger a two-leg purchase. Remember the price units are in cents and the allowed range is 0.01 to 0.99, so your calculator should guard against inputs outside that band. Include a column to estimate the expected edge after the Kraken-like Kalshi fee curve so you can compare net outcomes.

Practical steps to build an intra-market arb scanner

Set up a simple alert rule in your Excel sheet that watches for the condition bestAsk(YES) + bestAsk(NO) < 1.00 and notifies you when it occurs. Keep the workflow non custodial: you collect the signals, then place the two limit orders on Kalshi through your API key. Track the fee impact using Kalshi’s pricing formula and consider the impact of partial fills and slippage. This approach aligns with Kalshi’s binary structure and the fact that every contract has a guaranteed payoff of 1.00 to the winning side.

FAQ

What does triangular arbitrage look like on Kalshi markets?
It involves spotting a time when the best asks for YES and NO sum to less than 1.00, allowing you to buy both sides and lock a small edge after fees.
Do I need special software to run the Excel approach?
You can start with a standard spreadsheet and pull data from Kalshi’s REST API; the key is cleanly converting quotes into a 0.01 to 0.99 price grid and calculating the net edge.
Is this edge guaranteed to be risk-free?
No. Edge depends on price movements, feasibility of filling both sides, timing, and the Kalshi fee curve. Always account for slippage, fees, and settlement rules.
How does Kalshi settle these arbitrage opportunities?
Kalshi settles each market according to its written resolution rules. The edge exploited by arbitrage is a pricing discrepancy before settlement, not a guarantee of profit.
