Regulation & Legality 👩⚖️
Kalshi
A federally regulated Designated Contract Market. You can trade event contracts in the U.S. under a published rulebook with surveillance, dispute pathways, and controlled listings. If legality is your first filter, this is the fully regulated option.
Polymarket
Runs on chain and settles in USDC. U.S. trading has been restricted since a CFTC action, while the platform continues operating for non-U.S. users and has signaled plans to expand compliant access. Wallet management and jurisdiction rules matter much more here than on a traditional exchange.
Bottom line: Kalshi leans on exchange oversight and documented resolution. Polymarket leans on transparent smart contracts and public on-chain history. Different protections, different trade-offs for traders and investors.
Market Types & Event Variety 📈
Kalshi lists markets where every contract has a published rule set that names the event, the official data source, and the exact settlement conditions ($1 for Yes, $0 for No). Coverage includes inflation, interest rates, employment, weather, entertainment, and politics, with sports expanding through different partners.
Polymarket casts a wider net. It lists contracts across a presidential election, sports, culture, and tech. New markets can go live within hours of breaking news, so if you want the quickest listings and the broadest topical stream, Polymarket usually leads.
Liquidity, Fees, & Payout Structure 💲
Liquidity
Kalshi runs a central limit order book on a regulated exchange. Bids and asks meet in USD, with liquidity supported by market makers and distribution from fiat-facing partners. Polymarket uses an on-chain order book settled in USDC. Depth usually spikes around election news, court rulings, and big sports weekends.
Fees
Kalshi charges trading fees based on expected earnings, plus standard payment-rail costs where they apply. ACH can be free; card rails and certain transfers have posted fees. Polymarket has no trading fee on core markets, but you’ll pay small blockchain network fees when you move USDC. If you plan to trade headlines frequently, compare total costs (platform plus rails) before you pick a side.
Payouts
Both are binary. A winning “Yes” pays 1; a losing share pays 0. On Polymarket, that 1 is 1.00 USDC. Prices map to implied probabilities, so 0.63 reflects a 63% chance the outcome hits.
Deposits, Withdrawals, & Currency💰
Kalshi
Link a bank account and move money by ACH or bank transfer. No wallet setup, no keys to manage. Good if you want a more traditional path on a regulated platform.
Polymarket
USDC only. Connect a compatible crypto wallet on Polygon and fund it with USDC. Transfers are low-cost once you’re set up, but you’re responsible for keys and on-chain movements.
Timing Notes
ACH follows bank timing and compliance checks, so plan ahead. On-chain speed depends on the network and your wallet. If you expect heavy news flow (like political debates, CPI mornings, playoff Sundays), make sure funds are in place before volume hits.
In short, pick Kalshi for a regulated U.S. exchange with USD funding to trade politics and macro. Pick Polymarket for on-chain speed, USDC settlement, and a constant feed of new listings.
About Kalshi
Kalshi was founded by Tarek Mansour and Luana Lopes Lara in New York. In the year 2020, it received DCM status from the CFTC, becoming the first U.S. exchange for regulated event trading. That framework means posted rules and defined settlement for every event you trade.
Leadership and growth: Kalshi CEO Tarek Mansour leads the company; 2025 funding rounds drew investor interest and Bloomberg coverage, and the exchange reported record activity into November. What it’s known for today: macro releases like CPI and jobs, interest-rate decisions, weather, and politics, with sports expanding through partners.

About Polymarket
Polymarket launched in 2020 and is led by Polymarket CEO Shayne Coplan. Prices run from 0 to 1 in USDC and settle on chain, so each trade and payout is recorded on the blockchain and can be verified. The product began with an AMM and now uses a central limit order book to deepen liquidity and tighten spreads. It’s a go-to for fast, topical events across politics, sports, tech, and culture when news hits.
U.S. trading has been limited since a 2022 CFTC action, while non-U.S. users continue to trade. In 2025, the company announced a $112 million deal to acquire a CFTC-licensed exchange and clearinghouse, a big step toward winning the race on compliant U.S. availability.
How Do Prediction Markets Operate? 💭
Think of price as probability. In a prediction market, a “Yes” at 0.62 implies a 62% chance of that outcome. Traders buy and sell around news flow, polls, and opinions, and can exit early if the view changes. At resolution, winners receive 1 (or 1.00 USDC), losers receive 0. That binary payout is why prices feel like odds, whether you trade macro prints, sports, or a high-visibility election market that mentions Donald Trump by name.
Two quick tips that help: read the contract rules and make sure you agree with the listed data source and settlement trigger, and plan funding in advance of key listing moments so you’re not waiting for transfers while the market moves.
Final Thoughts on Kalshi and Polymarket
If you want a federally controlled lane with USD rails, Kalshi is the pick. It’s a CFTC-designated exchange with contract specs, surveillance, and clear rules. If you want on-chain speed and the widest stream of fresh listings, Polymarket is the best crypto option out there. For most North Americans, that’s the crux of Kalshi vs Polymarket: legality and access first, everything else follows.
A few tips: check the fee math before you trade news. Kalshi charges on expected earnings, while Polymarket has no trading fees, but you’ll pay small network costs. Verify your jurisdiction and chose your payment method in advance of a presidential election week or a big sports slate, and start small until you’re comfortable with how each prediction market settles an outcome.
