Question: I'm looking for the best prediction market that has the most liquidity and lowest fees.
If you mean the combination of deep liquidity and low trading costs, the two major U.S.-accessible names to compare right now are Kalshi and Polymarket.
Kalshi — U.S.-regulated exchange and generally the more straightforward choice for U.S. users. Its fees vary by market and contract price; its current general schedule can reach about $1.75 per 100 contracts at 50¢ (1.75% of contract notional at that point).
Polymarket — Very large global prediction-market venue, with a fee structure that depends on the market. Its current schedule says makers pay 0 fees, while takers pay fees on many categories; some geopolitical/world-event markets are fee-free.
Important U.S. distinction: 's international site currently says trading is blocked in the U.S. and directs U.S. users to US.

So there isn't a single platform that is unambiguously "most liquid + lowest fees" across every market. Liquidity can differ dramatically by individual contract, and the effective cost depends on whether you're making or taking liquidity.
If you tell me what you're trading (politics, sports, crypto, economics, etc.) and roughly how much per trade, I can compare Kalshi vs. Polymarket on specific markets, spreads, depth, and effective fees using current data.

Kalshi
A breakdown of how they compare on liquidity and fees helps determine the right fit:
Polymarket
Liquidity: The largest decentralized prediction market in the world. It dominates global volume for geopolitics, pop culture, and global world events, featuring massive order books and deep liquidity pools.
Fees: Exceptionally low. Geopolitical and world event markets are completely fee-free. For sports markets, it uses a probability-based taker fee peaking at just 0.75% at a 50/50 price point.
Access/Requirements: Operates on the Polygon blockchain, meaning you need cryptocurrency (USDC) to fund your account. (Note: Geoblocked for users in the United States unless using compliant workarounds, though regulations shift frequently).
Check out the platform details directly on Polymarket.
Kalshi
Liquidity: The premier federally regulated (CFTC-regulated) option in the United States. It boasts immense liquidity for U.S.-centric macroeconomics, politics, and increasingly deep pools for major U.S. sports leagues.
Fees: Uses a maker-taker model. Taker fees on mid-probability (50\cent ) contracts can peak around 1.75\cent per contract and scale down as probabilities approach 0% or 100%.
Access/Requirements: Fully legal and accessible for U.S. residents, allowing standard fiat currency (USD via bank transfer/ACH) without needing a crypto wallet.
Explore current contracts on Kalshi.
To help narrow down the best choice for you, tell me:
Are you located in the United States or internationally?
Do you prefer funding your account with traditional currency (USD) or crypto (USDC)?
What specific topics do you plan to trade the most (politics, sports, macroeconomics, crypto)?
Polymarket is usually the cheaper venue for many markets, especially if you use limit orders and trade categories with low or no fees.
Kalshi can be competitive, particularly for market makers or certain contracts, but taker fees are generally more noticeable.
If your priority is maximum liquidity
There is no single winner across every market:
For global politics, crypto, and some macro events, Polymarket has historically attracted substantial liquidity.
For U.S. event contracts and sports, Kalshi has grown rapidly and reported very large trading volumes.
Practical choice
Active trader / looking for tight spreads and low fees: start by comparing the same contract on both platforms; Polymarket often has the lower cost structure.
U.S. resident wanting a regulated exchange environment: Kalshi may be preferable depending on the market you want.
Large trades: liquidity matters more than headline fees—check order-book depth and bid/ask spread before entering.
For a more precise recommendation, the key details are:
Are you trading politics, sports, crypto, economics, or other events?
Are you in the U.S. or another country?
Are you a small retail trader (under ~$1k positions) or trading larger size?
Polymarket: Widely recognized as having the deepest global liquidity and lowest effective fees overall . Geopolitical, macroeconomic, and world events markets are completely fee-free, while sports markets use a low probability-based taker fee (peaking around 0.75% at a 50/50 price point). It operates on crypto/USDC rails, making it exceptionally fast, but it is decentralized and officially restricted for users physically located in the United States unless utilizing compliant access routes. Check out the Polymarket Platform Review on FTW USA Today for broader event coverage details.
Kalshi: The premier fully federally regulated (CFTC-regulated) exchange native to the United States. It features deep liquidity specifically tailored for U.S. politics, economics, and major domestic sports leagues. Kalshi uses a maker-taker model where fees scale based on the contract probability (peaking around 1.75¢ per contract at the 50% implied probability mark). Review the Kalshi Platform Overview on Sports Illustrated for a comprehensive breakdown of its legal status and banking options.
If you let me know what type of events you plan to trade (e.g., politics, macroeconomics, or sports) and your geographic region , I can help you choose the platform that fits your setup.
Bottom line: If I were choosing purely on liquidity + fees, I'd start with Polymarket, but I'd keep Kalshi open alongside it. The best execution can depend heavily on the specific contract: a market with a slightly higher headline fee can still be cheaper if its bid/ask spread is substantially tighter.
One important caveat: prediction markets are facing significant regulatory and market-integrity scrutiny, including recent concerns about insider trading and manipulation.
If you tell me whether you're mainly trading politics, sports, crypto, economics, or weather, I can compare Polymarket vs. Kalshi market-by-market, including the actual spread/liquidity and effective cost of a $1,000 trade.
A breakdown of how they compare reveals which platform fits your strategy best:
1. Kalshi
Strengths: Fully regulated by the CFTC as a designated contract market in the United States. Massive volume on major elections, economics, weather, and mainstream U.S. sports.
Liquidity: Exceptionally deep liquidity, particularly for macro-political and high-profile economic/sports contracts.
Fees: Uses a probability-based taker fee formula that peaks at roughly $1.75 per 100 contracts ($0.0175 per contract) for a 50/50 probability coin-flip market and scales down toward the extremes (0% or 100% probability). Resting limit orders (makers) or specific tiers pay lower or no fees, and standard ACH deposits/withdrawals are free.
2. Polymarket
Strengths: The largest decentralized/crypto-backed prediction market globally, offering incredible breadth of niche, global, pop-culture, and fast-moving political/crypto event coverage.
Liquidity: Industry-leading volume for global and crypto-native markets, with fast order-matching.
Fees: Features a dynamic probability-based taker fee (peaking around 0.75% to 1.50% per 100 contracts at a 50/50 price point). Crucially, Maker orders (resting limit orders that add liquidity) pay 0% fees and actually earn a maker rebate. If you use limit orders rather than market-taking orders, trading on Polymarket can be entirely fee-free.
Summary Recommendation
Choose Kalshi if you want a strictly US-regulated platform with seamless fiat/ACH banking and rock-solid liquidity on macroeconomic and political outcomes.
Choose Polymarket if you want maximum global market variety and are willing to use limit (maker) orders to completely bypass taker fees.
Are you planning to trade mostly using crypto/USDC (like Polymarket) or fiat/USD bank transfers (like Kalshi), and what specific category (politics, sports, or macroeconomics) are you focusing on?
1. Polymarket (Best for Global Liquidity & Lowest Sports Fees)
Liquidity: Massive global volume, particularly for politics, pop culture, macroeconomics, and crypto-native events.
Fees: Uses a probability-based taker fee structure (especially active on sports markets), peaking at a very low effective fee of around 0.75% at the 50/50 price point and scaling down for extreme probabilities.
How it works: Crypto-native. Settled entirely in USDC (stablecoins) on a high-speed chain. Requires a Web3 wallet and comfort with self-custody, which allows for lightning-fast global access but a steeper learning curve if you aren't in crypto.

2. Kalshi (Best for U.S. Regulated Safety & Deep Financial Markets)
Liquidity: Exceptional volume, especially following massive institutional backing and explosive growth in U.S. markets covering economics, elections, weather, and pop culture.
Fees: Competitive maker-taker model. On standard Yes/No contracts, fees average around 1.4% to 1.75% per transaction depending on contract probability and order type, with free ACH/wire deposits and withdrawals.
How it works: Fully regulated by the CFTC as a designated contract market in the United States. You fund your account using standard USD via traditional banking/ACH, making it the most seamless legal option for U.S. traders.

Polymarket — best overall for most serious traders
Usually has the largest pools of money trading on major questions.
Better price discovery when a market is popular.

Practical choice
Large political/election trades: Polymarket
Macro/economic data (Fed, CPI, jobs, rates): Kalshi is very competitive
High-frequency trading: Compare bid-ask spreads first; a cheaper fee is irrelevant if liquidity is poor
Small retail trades: Either works; usability may matter more than a few basis points
If I had to pick one purely on liquidity + fee efficiency, I would start with Polymarket. If I were a U.S.-based trader prioritizing regulation and easy deposits, I would consider Kalshi instead.
One caveat: prediction markets can have legal restrictions depending on where you live (for example, access rules differ between the U.S., UK, and other regions), so check the platform’s availability before depositing funds.
Polymarket (for global/crypto liquidity) and Kalshi (for regulated U.S. trading) are the best overall prediction markets balancing high liquidity and competitive fee structures.

Very strong global liquidity, especially politics, crypto, world events
Generally among the lowest; makers pay no fee and some markets have very low/zero fees
Fee-sensitive traders, global markets, crypto-native users

Often the strongest in regulated US markets and some high-volume categories
Usually higher than Polymarket for active trading
US users wanting regulated access and USD settlement
Manifold Markets
Large community but not real-money liquidity
No trading fees
Forecasting practice, not serious capital deployment
Strongest combination of deep order books and low costs in many major markets.
Particularly attractive if you trade frequently because fees matter more with high turnover.
Best if you are in the US and want regulated infrastructure: Kalshi
USD-based, exchange-style experience.
Often has excellent liquidity in its most popular markets.
Best approach for serious traders: use both
Compare the same contract across platforms.
The best execution is often whichever venue has the tighter spread and more depth at that moment.
A few things to check before depositing:
Bid/ask spread matters more than headline fees. A platform with a 0.5% fee but a 5-cent spread can be worse than one with a 1% fee and a tight spread.
Market depth matters if you trade more than a few hundred dollars.
Jurisdiction matters: availability and rules differ by country.
If you tell me your country (e.g., UK, US, EU) and whether you trade politics, sports, crypto, economics, or everything, I can narrow it down to the best venue.
