Kalshi vs Polymarket for Irish Users (2026 Comparison)

Kalshi and Polymarket: What They Are

Kalshi and Polymarket are the two most prominent US-regulated prediction market platforms. They share a common regulatory framework (CFTC oversight) and a similar product concept — contracts that pay out based on real-world event outcomes — but differ significantly in structure, market focus, and international accessibility.

Kalshi

Kalshi launched in 2021 as the first CFTC-regulated prediction market exchange in the United States. It operates as a designated contract market (DCM), which gives it a more formal regulatory status than Polymarket's no-action letter framework. Kalshi's market focus has historically been on financial and economic outcomes — Federal Reserve rate decisions, inflation data, economic indicators, and US political events. Kalshi uses USD (not crypto) for all transactions, which removes the EUR-to-USDC conversion friction that Polymarket imposes on European users.

In 2025-2026, Kalshi expanded aggressively into sports markets (following a legal fight that established sports event contracts as CFTC-permissible), and partnered with Wealthsimple to launch a prediction market product in Canada — the first major licensed prediction market product outside the US. Kalshi's business model is B2B as well as B2C, licensing its technology to partners like Wealthsimple.

Polymarket

Polymarket launched in 2020 and operates as a decentralised prediction market on the Polygon blockchain. Unlike Kalshi, which is fully centralised and fiat-denominated, Polymarket uses USDC (a stablecoin) for all transactions and relies on the UMA protocol for decentralised market resolution. This creates a more open, peer-to-peer market structure with generally deeper liquidity on political events — Polymarket's speciality.

Polymarket holds a CFTC no-action letter rather than a formal DCM designation, meaning its regulatory standing is more informal than Kalshi's. However, Polymarket has operated without incident since 2020 and has built the world's deepest liquidity pool for political prediction markets. Its international accessibility is broader than Kalshi's — Polymarket applies geo-blocks selectively (blocking US states that restrict it) but has not blocked Ireland.

Key Differences — Kalshi vs Polymarket

Can Irish Users Access Kalshi?

This is the key question — and the honest answer is: access is restricted for most Irish users on Kalshi's main platform.

Kalshi has historically focused on the US market. Its main platform (kalshi.com) requires users to be US residents or citizens, and international users attempting to register from Irish IP addresses will typically encounter geo-block restrictions. Unlike Polymarket, which explicitly allows non-US users (excluding specific geo-blocked regions), Kalshi's default position is US-only, with limited international exceptions.

Kalshi has been expanding its international footprint, and the situation may evolve — check kalshi.com directly for the current registration status from Ireland. As of our last review in mid-2026, the main Kalshi platform is not reliably accessible to Irish users without a US connection.

Wealthsimple Predict — Canada Only

Kalshi's most significant international expansion is its partnership with Wealthsimple to launch "Wealthsimple Predict" — a regulated prediction market product for Canadian users. This is a meaningful development for the prediction market space: it represents the first major licensed prediction market product outside the US. However, Wealthsimple Predict is Canada-only and not accessible from Ireland. The product is built on Kalshi's underlying technology but distributed under Wealthsimple's Canadian financial services licence — Irish users cannot access it.

Can Irish Users Access Polymarket?

Yes — Polymarket does not geo-block Ireland. Irish users can register and trade with a MetaMask or Web3 wallet, using USDC deposited from a crypto exchange. See our full Polymarket Ireland guide for the detailed setup walkthrough including fees, KYC process, and deposit mechanics.

The short summary: accessible but not frictionless. USDC-only deposits, EUR conversion costs, and no GRAI licensing are the main friction points.

The Licensing Problem for Irish Users

Neither Kalshi nor Polymarket holds a GRAI (Gambling Regulation Authority Ireland) licence or any EU-level gambling/financial authorisation. This is the central issue for Irish users evaluating either platform.

Both platforms are regulated by the US CFTC, which is a legitimate regulatory body — but one with zero jurisdiction over Irish user complaints. If you experience a dispute on either platform:

• You have no GRAI complaint pathway
• You have no EU MiCA framework protection (neither platform has sought MiCA authorisation)
• Your only recourse is the platform's internal appeals process or, theoretically, the US CFTC — impractical for retail Irish users
• There is no segregated fund requirement protecting your balance under Irish law

This is not a reason not to use these platforms — it is information to make an informed decision. Both Kalshi and Polymarket have strong operational track records. The question is whether you want that consumer protection layer, and what you're willing to trade for the unique market access they offer.

Our Recommendation for Irish Users

Since neither Kalshi nor Polymarket currently holds GRAI authorisation, Irish users seeking consumer protection can access these licensed platforms instead:
