When it comes to the ultimate showdown of liquidity and fees, the two undisputed giants are Polymarket and Kalshi . Which one is "best" depends heavily on whether you prioritize raw global volume or strict U.S. regulatory backing.
Here is how they stack up on liquidity and fees:
Summary Verdict
If you'd like, let me know:
I can help you choose the exact platform that fits your strategy.
If your priorities are **(1) maximum liquidity and (2) low trading costs**, I’d put **Polymarket** and **Kalshi** at the top, but the winner depends on what you trade. ### My pick: Polymarket **Polymarket is probably the best overall choice for a high-volume trader** if you're eligible to use it.
If your priorities are (1) maximum liquidity and (2) low trading costs, I’d put Polymarket and Kalshi at the top, but the winner depends on what you trade.
Polymarket is probably the best overall choice for a high-volume trader if you're eligible to use it.
C × p × (1-p)), rather than 4–7% of your entire position. Kalshi may be preferable if you specifically want a U.S.-regulated exchange and U.S.-dollar infrastructure.
| Polymarket | Kalshi --- | --- | --- Liquidity | 🟢 Excellent | 🟢 Excellent Low fees for makers | 🟢 0% | 🟡 Depends on market Low fees for takers | 🟢 Often competitive | 🟢 Competitive Global/event markets | 🟢 Excellent | 🟡 More U.S.-focused U.S. regulatory structure | 🟡 More complicated | 🟢 CFTC-regulated exchange Crypto/on-chain | 🟢 Yes | 🟡 Limited My overall pick | 🥇 Polymarket | 🥈 Kalshi
One important caveat: "most liquidity" isn't the same as "lowest effective trading cost." For a large order, I would compare the actual order-book depth + spread + fees for the specific contract you're trading. A nominally cheaper venue can be much more expensive if your order moves the market.
Also, the regulatory situation is changing rapidly in the U.S.; several states are currently challenging prediction-market operators, so availability can depend on where you live.
If you tell me what type of markets you trade (politics, sports, crypto, Fed rates, etc.) and roughly how much you trade per position, I can compare the effective fees and liquidity of Polymarket vs. Kalshi for your use case.
If your priorities are **(1) maximum liquidity and (2) low trading fees**, I’d narrow it to **Polymarket vs. Kalshi**. ### My pick: Polymarket For a trader who cares primarily about **deep markets, tight spreads, and low friction**, I’d currently lean **Polymarket**.
If your priorities are (1) maximum liquidity and (2) low trading fees, I’d narrow it to Polymarket vs. Kalshi.
For a trader who cares primarily about deep markets, tight spreads, and low friction, I’d currently lean Polymarket.
| Polymarket | Kalshi --- | --- | --- Liquidity | 🟢 Extremely strong, especially major political/sports/crypto markets | 🟢 Extremely strong, particularly U.S. event markets Taker fees | Typically ~0–3.5¢ per $1 contract depending on category/price | Typically higher on many contracts; fee schedule varies Maker fees | 0; eligible makers receive rebates | Usually 0, but some markets have maker fees Fee-free markets | Geopolitical/world-event markets | Some products have special schedules Trading currency | USDC | USD Regulatory position | Offshore/crypto-based; more regulatory uncertainty | U.S.-regulated CFTC exchange Best for | Lowest friction + broad/global markets | U.S. access + regulated environment
Polymarket's current fee structure is particularly attractive if you're a maker: makers aren't charged trading fees, while eligible makers can actually receive rebates. Taker fees vary by category, with rates such as 4% for politics/finance/tech and 5% for sports/economics/general; the actual dollar fee depends on the contract price. Geopolitical markets are currently fee-free.
Kalshi is also very liquid and has been expanding its market-making infrastructure; it recently launched a formal market-maker program and is attracting institutional liquidity. Kalshi Help Center Reuters Its standard fee schedule, however, generally makes immediately executed/taker trades more expensive than a comparable maker trade on Polymarket.
One important distinction: Kalshi has the stronger U.S. regulatory footing, while Polymarket's offshore/crypto structure carries more regulatory and access considerations. There are also currently significant legal disputes over prediction-market regulation in the U.S.
One caveat: the cheapest venue can change on a market-by-market basis. A market with a 1¢ tighter spread on Kalshi can easily outweigh a nominal fee difference.
If you tell me whether you're primarily trading politics, sports, crypto, economics, or weather, I can compare the two specifically on current liquidity, bid/ask spreads, and effective round-trip cost for that category.

Summary Recommendation
To help narrow this down, what types of events do you plan on trading (e.g., politics, macro economics, or sports) and do you prefer funding with a traditional bank account or a crypto wallet?
If your priorities are **(1) maximum liquidity and (2) lowest trading costs**, I’d narrow it to **Kalshi vs. Polymarket**. ### My pick: Polymarket for lowest fees; Kalshi for deepest U.S. liquidity | | **Polymarket** | **Kalshi** |
If your priorities are (1) maximum liquidity and (2) lowest trading costs, I’d narrow it to Kalshi vs. Polymarket.
| Polymarket | Kalshi | |
|---|---|---|
| Liquidity | 🟢 Excellent, especially politics/crypto | 🟢 Excellent, especially U.S. sports |
| Fees | 🟢 Very low for makers; 0% in some markets | 🟡 Generally higher |
| Maker fee | 0% | Varies |
| Taker fee | ~4–7% of the probability component depending on category | Formula-based, generally around 7% coefficient |
| Best for | Politics, crypto, global events | U.S. sports, macro, regulated U.S. trading |
| Regulation | Polymarket US is CFTC-regulated; international product has different regulatory status | CFTC-regulated |
| Overall | Best fee structure | Best U.S. liquidity/coverage |
Polymarket's current fee schedule is particularly attractive if you're able to provide liquidity rather than take it: makers pay 0%, while taker fees vary by category. Geopolitical/world-event markets currently have zero trading fees altogether.
Kalshi's standard fee formula is roughly 0.07 × contracts × price × (1-price), although some markets have lower coefficients and high-volume traders can receive better rates. Its February 2026 schedule, for example, puts S&P 500/Nasdaq-100 markets at a 0.035 coefficient.
On raw volume, Kalshi has recently been ahead: one August 2026 comparison reported roughly $33B of June 2026 transactions on Kalshi vs. $14.5B on Polymarket. However, liquidity is highly market-specific—Polymarket can be considerably deeper in politics and crypto, while Kalshi has been particularly strong in sports.
One important distinction: the lowest nominal fee isn't necessarily the lowest trading cost. For a serious trader, I would compare spread + slippage + explicit fee for the specific contracts you trade. A 0.5% fee with a tight spread can be cheaper than a nominally fee-free market with poor depth.
If you tell me what you want to trade (sports, politics, crypto, economics, etc.) and roughly how much per trade, I can compare the actual all-in cost and liquidity of Kalshi vs. Polymarket for your use case.
If your priorities are **(1) maximum liquidity and (2) low trading fees**, I’d put **Polymarket** first overall, with **Kalshi** as the strongest U.S.-regulated alternative. | | **Polymarket** | **Kalshi** | |---|---|---|
If your priorities are (1) maximum liquidity and (2) low trading fees, I’d put Polymarket first overall, with Kalshi as the strongest U.S.-regulated alternative.
| Polymarket | Kalshi | |
|---|---|---|
| Liquidity | 🥇 Generally the deepest overall | Very strong, especially U.S. markets |
| Taker fees | ~0–1.75¢ per $1 contract at 50% probability, depending on category | ~1.75¢ per $1 contract at 50% probability under its general schedule |
| Maker fees | 0% on standard markets | Usually 0%, but some markets have maker fees |
| Market selection | Excellent, particularly politics, crypto, geopolitics, world events | Excellent U.S. economic, sports, politics, financial/event markets |
| Regulation | More complicated jurisdictionally | CFTC-regulated U.S. exchange |
| Best for | Maximum liquidity + broad market selection | U.S. users prioritizing regulatory structure |
Polymarket is currently describing itself as the world's largest prediction market, and its liquidity programs are explicitly designed to deepen order books and tighten spreads.
Its current fee structure is particularly attractive if you provide liquidity with limit orders: maker fees are 0%, while taker fees vary by category. For example, politics/finance/tech markets have a 4% fee rate and sports/general markets 5%; the actual dollar fee is multiplied by p × (1-p), so the maximum occurs around 50% probability. Geopolitical/world-event markets can be completely fee-free.
Kalshi is the one I'd choose if being on a federally regulated U.S. exchange is more important to you than having the broadest/deepest market ecosystem. Its current general fee schedule uses 0.07 × contracts × P × (1-P) for takers, while certain markets have different schedules. kalshi.com Kalshi has also been expanding its institutional infrastructure and recently partnered with Nasdaq on trade surveillance.
Don't judge "lowest fees" purely by the posted commission. Spread + slippage + fee is your real trading cost.
For example, a market with a 0% maker fee but a 1¢ wider bid/ask spread can be more expensive than a market charging a small commission with a very tight spread. For large trades, liquidity becomes especially important.
Bottom line:
If you're planning to trade $10k, $100k, or $1M+, the answer gets more interesting—I can compare the actual spread + fees + available liquidity on Polymarket vs. Kalshi for the kinds of markets you want to trade.

If your priorities are (1) maximum liquidity and (2) lowest trading costs, I’d narrow it to Kalshi vs. Polymarket.
| Kalshi | Polymarket | |
|---|---|---|
| Liquidity | 🟢 Excellent, particularly sports and major U.S. events | 🟢 Excellent, especially major politics/world events |
| Taker fees | Up to ~1.75¢/contract at 50¢ | Category-dependent; roughly 0–1.75¢ per $1 contract at the midpoint |
| Maker fees | Generally very low/zero on many markets | 0%, plus maker rebates on eligible markets |
| Exit fee | Generally no separate sell fee | Fee can apply when trading, depending on market |
| U.S. accessibility | 🟢 Strong; CFTC-regulated exchange | 🟢 U.S. platform now available, but regulatory situation is more complicated |
| Best for | High-volume trading, sports, macro, U.S. events | Politics, geopolitics, global events, crypto |
Polymarket's current fee schedule is particularly interesting: taker fees range from 4% to 7% of the p × (1-p) component, depending on category, while makers pay zero and can receive rebates. Geopolitical/world-event markets are currently fee-free.
Kalshi's core fee formula is approximately $0.07 × contracts × p × (1-p), meaning a contract at 50¢ costs about 1.75¢ per contract for a taker. The fee falls rapidly as the price approaches 0¢ or 100¢.
If you're a maker—you place resting limit orders rather than crossing the spread—both can be extremely cheap. Polymarket explicitly has 0% maker fees plus liquidity/maker rebates.
If you're a taker, I'd generally lean Kalshi for frequent trading because its fee structure is straightforward and you're not paying a fee again simply because you later sell the position. For very large orders, however, spread + order-book depth matters more than the headline fee.
And liquidity is highly market-specific. The biggest Kalshi markets can have enormous depth, while Polymarket can be substantially better for particular international/political contracts. Current reporting also indicates Kalshi remains extremely strong in overall U.S. prediction-market volume.
Bottom line:
If you tell me what you want to trade (sports, politics, Fed/economics, crypto, etc.) and roughly how much per trade, I can compare the actual current spreads, liquidity, and fees and tell you which platform is cheapest for your strategy.
