Polymarket vs Kalshi: Which Prediction Market Leads After Midterms?
Why Traders Are Comparing These Two Platforms After Election Day
The US midterms on November 3, 2026, put Polymarket and Kalshi in the spotlight. Kalshi reported more trading volume.
That is only part of the story, though, because the two work in very different ways.
Below is how they compare on rules, fees, volume, and access, with a close look at India. Sources were checked on November 13, 2026, and details can change.
What Is Polymarket vs Kalshi? A Simple Explanation for Beginners
Both sites let people trade on yes or no questions about the future. Will a party win the House? Will interest rates fall? Each question becomes a market.
Polymarket’s main site runs on crypto. Traders use a wallet and a dollar-linked token. Kalshi is a US exchange. It uses normal US dollars and follows CFTC rules.
Think of Polymarket as a crypto-based prediction marketplace and Kalshi as a CFTC-designated US exchange. Both have access rules, but they are built in different ways.
How Do Prediction Markets Turn Opinions Into Simple Share Prices?
A share in a standard binary contract costs between 0 and 1 dollar. A winning share pays 1 dollar. A losing share pays nothing.
Say a share costs 62 cents. The market sees roughly a 62% chance. If it wins, the buyer gets 1 dollar back, which is 38 cents of gross profit before fees.
If it loses, all 62 cents are gone. The basics of how prediction markets work are the same on both sites. Each market’s own rules say how the result is decided.
What Is Polymarket, and How Does Its Crypto-Based Platform Work?
Polymarket’s main site runs on crypto. Traders connect a wallet and fund it with a token like the USDC stablecoin.
Trades happen on the Polygon blockchain. Polymarket’s documents say trades use a token called pUSD, which is backed by USDC.
Polymarket US is a separate product. Its approval does not automatically cover the main site. News appears on Polymarket’s official X account.

What Is Kalshi and Why Does the CFTC Oversee Its Event Contracts?
Kalshi lists Kalshi event contracts in US dollars. The CFTC’s official registry shows Kalshi as a designated contract market since November 3, 2020. The same registry lists QCX LLC, doing business as Polymarket US, as designated on July 9, 2025.
That label does not mean the CFTC guarantees any contract or outcome. It means the exchange works under CFTC rules.
Kalshi also takes traders from many countries. People outside the US can add money by debit card, wire, or crypto. News and notices appear on Kalshi’s official X account.
Polymarket vs Kalshi: How Do Fees, Liquidity, and Access Compare?
As of November 13, 2026, the main differences look like this:
Factor | Polymarket | Kalshi |
Structure | Crypto-based, wallet access | Regulated US exchange |
Status | Polymarket US is a designated contract market; the main site is separate. | Designated Contract Market |
Funding | USDC on Polygon turned into pUSD. | US dollars, plus card, wire, or crypto abroad |
Fees | Taker fees by category; makers pay none. | Fee set per market |
Liquidity | Differs by market | Differs by market |
Polymarket’s fee documentation says makers are never charged and geopolitical markets are free. Politics markets can still carry taker fees.
Kalshi’s fee help page says it charges a fee on the expected earnings of a contract. Some markets use different fees. Here is a standard example:
Platform | Fee on 100 contracts at $0.50 |
Polymarket, a politics taker | $1.00 |
Kalshi, standard taker | $1.75 |
This uses Polymarket’s 4% politics taker rate and Kalshi’s standard 7% taker formula.
Real fees can change by market, rebates, and the current schedule. Deposit and withdrawal costs are separate from trading fees.
Which Platform Has Higher Trading Volume and Market Liquidity?
Volume is how much money changed hands. Liquidity is how easily you can buy or sell without moving the price. Makers put orders on the book, and takers fill them.
On volume, Polymarket vs Kalshi gives two different totals. On November 4, 2026, Kalshi said its midterm markets passed 2.5 billion dollars in its company midterm recap. No independent check of that number was found.
A midterm research report counted about 2 billion dollars across both sites from January 5 to November 4. Kalshi had about 1.53 billion of it, and Polymarket had 474 million. It counts only the taker side, with each contract valued at its 1-dollar payout.
The two counts use different methods, so they cannot be compared directly. Both still put Kalshi ahead. But more volume does not prove better liquidity, so no liquidity winner is named here.
Can Indian Residents Legally Trade on Polymarket or Kalshi Today?
Three questions get mixed up here. Is it legal? Does the website open? Does the platform accept Indian users? Each has its own answer.
The Promotion and Regulation of Online Gaming Act, 2025, started on May 1, 2026.
A government briefing on the Act says it bans online money games, whether they rely on chance, skill, or both.
Whether it covers a given product depends on how that product works and how the law is read. No court ruling reviewed here settles every event contract.
On April 25, 2026, the IT ministry issued a notice naming Polymarket among sites it called illegal and blocked.
It also warned VPN providers not to help users reach them. Polymarket has been reported as unreachable in India.
Kalshi is less clear. A national business report said in June 2026 that Kalshi added India to its restricted-jurisdiction list. But the October 2026 agreement reviewed here does not name India in that list.
Rules and laws can change, so Indian residents should confirm country rules directly with Kalshi before trading.
Crypto tax is a separate matter. India’s crypto tax rules do not decide whether a prediction product is allowed.
What Are the Main Risks of Using Prediction Markets Right Now?
Losses: a losing share drops to zero.
Thin trading: big price gaps can make selling costly.
Unclear results: disputes over how a market ends can delay payouts.
Access limits: sites can close regions, and governments can block them.
Locked funds: a platform limit or legal action could cut off an account. This is a possible risk, not a confirmed problem on both sites.
Are Prediction Market Prices Reliable Signals of Public Opinion?
Prices can hold useful clues, since traders put real money behind their views. Kalshi said that, among races settled by 6:00am ET on November 4, its favored candidates won 479 of 487. But winning many safe races does not prove markets beat polls in close contests.
Small markets swing easily, and traders are not a random sample of voters. A price is a chance estimate, not a verified poll or an official count.
What Should Traders Know Before Choosing Polymarket or Kalshi?
The Polymarket vs Kalshi answer depends on what is being measured:
Regulation: Kalshi and Polymarket US are designated contract markets. Polymarket’s main site is crypto-based.
Midterm volume: available estimates put Kalshi ahead, using different methods.
Fees: each market needs its own check.
Liquidity: not proven here.
Government action and reported platform limits make legal advice important before any money moves.
Neither platform leads in every category. One is a regulated exchange, the other is built on crypto, and the numbers keep changing.
