Prediction markets traded billions of dollars in volume during the 2024 election cycle. That surge made Kalshi vs Polymarket one of the most searched comparisons in finance and politics.
Both platforms let you bet on real-world outcomes, from election results to economic data. But they work very differently under the hood.
This guide breaks down kalshi vs polymarket on the things that matter most: regulation, fees, contract types, and who can actually use them.
What Are Prediction Markets?
A prediction market is a platform where users buy and sell contracts tied to future events. If you think a candidate will win, you can buy a yes share. If the event happens, that share pays out at $1.
The price between $0 and $1 reflects the market's view of how likely the event is. A share trading at $0.65 means the market estimates a 65% chance.
These markets have been studied as forecasting tools, since pooled money often beats individual experts. They are also a way to express opinions on news, sports, and economic trends.
Kalshi vs Polymarket at a Glance
Kalshi is a regulated U.S. exchange. Polymarket runs on blockchain technology and uses crypto for trades.
Kalshi is approved by the Commodity Futures Trading Commission (CFTC). Polymarket settled with the CFTC in 2022 and is officially blocked for U.S. users, though many still access it through workarounds.
Kalshi accepts U.S. dollars via debit card or bank transfer. Polymarket runs on the Polygon blockchain and uses USDC, a stablecoin pegged to the U.S. dollar.
How Kalshi Works
Kalshi calls its contracts event contracts. They cover everything from inflation numbers and Federal Reserve decisions to weather, awards shows, and sports.
Regulation and Safety
Kalshi is regulated as a Designated Contract Market by the CFTC. That means it follows the same legal framework as commodity futures exchanges like the CME.
For U.S. residents, this regulation is the main draw. Your funds sit in segregated accounts, and the platform has to follow strict rules around fraud and market manipulation.
Fees and Funding
Kalshi charges trading fees that vary by contract and price. Fees are typically a small percentage of the trade size and may be lower for limit orders that add liquidity.
You can deposit U.S. dollars from a bank account or debit card. Withdrawals usually take one to three business days.
How Polymarket Works
Polymarket is one of the largest crypto-based prediction markets. It runs on Polygon, an Ethereum-compatible blockchain, and uses USDC for all trades.
How Trading Happens
You connect a crypto wallet to Polymarket and deposit USDC. From there, you buy yes or no shares on events.
The order book is fully on-chain. Smart contracts handle settlement when events resolve, which removes the need for a central clearinghouse.
Markets and Volume
Polymarket gained massive attention during the 2024 U.S. presidential election. Some single markets traded over $3 billion in volume.
It offers contracts on politics, sports, crypto prices, pop culture, and more. The range tends to be broader than Kalshi, partly because Polymarket faces fewer regulatory limits.
Access for U.S. Users
Polymarket is officially geoblocked for U.S. residents. Some users access it through virtual private networks, but doing so may violate the platform's terms and U.S. law.
If you are in the U.S., Kalshi may be the only fully compliant option among the two.
Kalshi vs Polymarket: Side-by-Side
Here is a quick comparison of the main differences.
Regulation: Kalshi is CFTC-regulated. Polymarket is not regulated in the U.S.
Funding: Kalshi accepts U.S. dollars. Polymarket uses USDC on Polygon.
Availability: Kalshi works for U.S. residents. Polymarket is geoblocked in the U.S.
Market variety: Polymarket typically offers more contracts and bigger volume. Kalshi has fewer markets but more legal certainty.

Risk and Responsible Use
Prediction markets are not the same as investing in stocks or ETFs. Outcomes are binary, and you can lose your entire stake on a single trade.
Many financial planners suggest treating prediction markets as a small slice of your overall money, not a core wealth strategy. Some people use them to hedge real-world risks, like a farmer betting on weather. Thinking through saving vs investing can help you size that slice.
If you want to put more serious money to work, a traditional broker may make more sense. Apps like Robinhood and Public let you buy stocks, ETFs, and Treasury products with low or no fees. Robinhood also opened up Robinhood futures trading for users who want exposure to commodities and indexes.
