Kalshi Greenland: how it compares to Polymarket and PolyArb

Kalshi is a transactional event exchange; Polymarket is a decentralised prediction-market CLOB on Polygon.

What "Kalshi Greenland" usually refers to

Searches like "Kalshi Greenland" often point to a Kalshi-listed event involving Greenland (a geography or policy question) or to people comparing Kalshi’s US-focused markets with Polymarket’s global, on-chain markets. I’m not certain which exact Kalshi market you meant; Kalshi hosts CFTC-regulated event contracts while Polymarket runs on Polygon using pUSD and the Gnosis CTF for outcome tokens. If you need the precise Kalshi listing, check Kalshi directly.

How Polymarket differs from Kalshi

Polymarket is a decentralised CLOB on Polygon where outcome shares are ERC-1155 tokens (CTF) and settlement uses UMA; trading settles in pUSD. Polymarket sponsors gas via a Relayer and exposes public REST APIs and a market WebSocket for real-time book data. Kalshi operates differently as a centralized, regulated event exchange; the two attract different user bases and regulatory constraints.

Why traders care about intra-platform arbitrage

On Polymarket you can find intra-market arbitrage when the sum of best-ask prices across outcomes is less than $1.00. That gap—called the edge—is tradable by buying a complete set and later redeeming winning shares. PolyArb automates that process, scanning markets and executing with low latency to lock in short-lived spreads.

How PolyArb fits your workflow

PolyArb runs live today as a non-custodial service: $99/month, 40ms latency vs ~800ms for many free bots, Telegram and Discord alerts, and a $7.62 minimum guaranteed edge per trade. It connects to Polymarket order books, places FAK orders, and handles CTF splits/merges through the Relayer so you don’t manage gas or contract calls manually.

Risks and practical notes

Arbitrage on any platform carries risks: resolution disputes (UMA on Polymarket), partial fills and slippage, fee changes, smart-contract risk, and settlement timing. PolyArb reduces execution latency and provides alerts, but these operational risks remain—treat this as execution tooling, not investment advice.

FAQ

Is Kalshi the same as Polymarket?

No. Kalshi is a separate event exchange with its own regulatory model. Polymarket is a decentralised CLOB on Polygon using pUSD and the Gnosis CTF; they have different mechanics, settlement, and user access.

Can I arbitrage between Kalshi and Polymarket?

Cross-platform arbitrage is possible in theory but falls outside PolyArb’s focus. PolyArb targets intra-Polymarket arbitrage where you buy complete sets on the same market and redeem via CTF.

What does PolyArb guarantee?

PolyArb guarantees a $7.62 minimum edge per trade, low-latency execution (40ms), non-custodial operation, and Telegram/Discord alerts. This is tooling for execution; it does not eliminate settlement or oracle risks.
