Polymarket vs Kalshi, explained
By the Cent Signals editorial desk. Reviewed June 3, 2026.
Polymarket and Kalshi are two prediction-market platforms that price real-world events as probabilities. This page compares them on the facts only: regulator and legal status, settlement, fees, available regions, and resolution source. Cent Signals is a free, independent desk that tracks Polymarket activity and explains how prediction markets price probability, not trading advice. It reads as of 2026 and is documentation only, describing how each platform is structured rather than guiding any choice between them.
What these two platforms are
Both Polymarket and Kalshi let participants take positions on the outcome of future events, with each contract priced between zero and one dollar so the price reads as the market's implied probability. The mechanics differ in where the contracts live and who oversees them. Kalshi is, as of 2026, a CFTC-regulated Designated Contract Market domiciled in the United States, so its event contracts sit inside the federal commodities framework. Polymarket is an on-chain market that settles in USDC on the Polygon blockchain and, in 2026, received a CFTC amended designation to operate a US-facing exchange alongside its existing platform.
Cent Signals covers Polymarket specifically. It reads the public prices, volume, liquidity, and wallet activity on Polymarket and explains what those figures describe. If you are new to reading those numbers, the companion explainer on what Polymarket is and how it works walks through the basics first.
Feature comparison (as of 2026)
The table sets Polymarket and Kalshi side by side on the dimensions that actually differ. Each cell describes a current fact as of 2026. Fee schedules, regional access, and regulatory status all change over time, so treat each platform's own published terms as the authoritative source.
| Capability | Polymarket | Kalshi |
|---|---|---|
| Regulator and legal status (as of 2026) | On-chain market; 2026 CFTC amended designation for a US exchange | CFTC-regulated Designated Contract Market, US-domiciled |
| Settlement asset and venue | USDC on the Polygon blockchain | US dollars through the regulated exchange |
| Resolution source (as of 2026) | Decentralized oracle with UMA dispute system | Exchange rules and named settlement source under CFTC oversight |
| Account and identity verification required | Partial (Wallet-based; fiat on-ramps may add checks) | Yes: KYC required |
| On-chain, publicly inspectable activity | Yes | Partial (Exchange records, not on-chain) |
| Available regions (as of 2026) | International, plus US exchange after 2026 designation | US states (some categories limited) and many countries |
| Trading fees (as of 2026) | Category taker fees; makers pay none; US exchange flat taker fee | Per-contract transaction fees; $2 bank withdrawal; no settlement fee |
Yes, Partial, and the short value cells above describe the current state of each platform as of 2026. They are not ratings and do not rank one platform above the other.
Regulator and legal status
The clearest structural difference, as of 2026, is regulatory posture. Kalshi operates as a CFTC-regulated Designated Contract Market, which means its event contracts are listed and overseen within the United States federal commodities regime. Polymarket spent earlier years operating its market offshore and, in 2026, received a CFTC amended designation that lets it run a US-facing exchange while its broader on-chain platform continues. The result is two different legal shapes around economically similar contracts. This is a description of where each platform stands, not a judgement about either one.
Settlement and resolution source
How a market pays out is the other place the two diverge. On Kalshi, each contract names a settlement source in its terms and resolves under exchange rules subject to CFTC oversight, with a regulated path for disputes. On Polymarket, resolution happens on-chain through a decentralized oracle that uses the UMA optimistic-oracle dispute system, where token holders can propose and challenge an outcome before it finalizes. One settles through a regulated exchange process and the other through an on-chain oracle. Because the figures Cent Signals publishes are snapshots of public Polymarket data, reading the methodology page explains exactly which public sources those numbers come from.
Fees and available regions
On fees, as of 2026, Polymarket historically charged nothing to trade and has since layered in a taker-fee model that varies by category, while maker orders that add liquidity to the book pay no fee; its US exchange applies a flat taker fee. Kalshi charges per-contract transaction fees on executed trades, with no charge on resting orders that never fill, no ACH deposit fee, and a flat fee on bank withdrawals. On regions, Kalshi reports availability across US states, with some categories limited in a small number of states, plus access in many countries internationally. Polymarket operates internationally and added its US-facing exchange after the 2026 designation. Both sets of figures move, so the platforms' own current pages are the authoritative reference.
How Cent Signals fits in
Cent Signals is not a platform and not a place to take a position. It is a free, independent reading desk for the public data Polymarket exposes. It indexes markets with real activity behind them and the wallets that transact large notional, then explains what the prices and positions describe. You can see that in practice on a market page such as the market on a 50-plus basis point Fed rate cut after the June 2026 meeting, or on a tracked wallet such as this Polymarket trader and the positions it currently holds. Those pages report observations of public data, never instructions.
Frequently asked questions
Are Polymarket and Kalshi regulated the same way?
No. As of 2026 Kalshi operates as a CFTC-regulated Designated Contract Market domiciled in the United States, so its event contracts sit inside the federal commodities framework. Polymarket runs an on-chain market that settles in USDC on the Polygon network and, in 2026, received a CFTC amended designation to operate a US exchange alongside its existing platform. The two carry different regulatory histories and structures.
How does each platform settle and resolve a market?
Kalshi resolves each contract under exchange rules subject to CFTC oversight, with a defined settlement source named in the contract terms and a regulated dispute path. Polymarket resolves on-chain through a decentralized oracle, using the UMA optimistic-oracle dispute system, where token holders can challenge a proposed outcome. One settles through a regulated exchange process and the other through an on-chain oracle. Both publish their resolution sources, as of 2026.
What fees does Polymarket charge compared to Kalshi?
As of 2026, Polymarket historically charged no trading fees and has since introduced a taker-fee model that varies by category, while maker orders that add liquidity pay no fee; its US exchange uses a flat taker fee. Kalshi charges per-contract transaction fees on executed trades, no fee on resting orders that never trade, no ACH deposit fee, and a flat fee on bank withdrawals. Both publish current fee schedules, which change over time.
Where can people use Polymarket and Kalshi?
As of 2026, Kalshi reports availability across US states, with some categories limited in a handful of states, plus access in many countries internationally where it is not separately regulated. Polymarket operates internationally and, following its 2026 CFTC amended designation, runs a US-facing exchange. Available regions for both change as rules evolve, so the platforms' own current terms are the authoritative source.
Do I need an account to use Polymarket or Kalshi?
As of 2026, Kalshi requires account registration and identity verification, including government identification and, for US users, the documents tied to its CFTC compliance. Polymarket is an on-chain market reached through a crypto wallet, with fiat on-ramps that can create a wallet during signup. Cent Signals itself sits apart from both: it requires no account and no wallet, because it only reads and explains public data and never routes a trade.
Is Cent Signals affiliated with Polymarket or Kalshi?
No. Cent Signals is an independent editorial desk. It is not operated by, funded by, or partnered with either platform. It reads public Polymarket data and explains how prediction markets price probability. It does not accept orders, custody funds, route trades, or connect wallets, and any outbound links to either platform are reference only.
