Which Prediction Market Is Best for Each Category

How Prediction Market Contracts Resolve

Resolution is the part of prediction market trading that most guides skip over, and it's the part that bites you if you don't understand it going in.

Resolution Sources

Every Kalshi contract has a designated resolution source written into the rules before trading opens. For economic markets, Kalshi uses official government data releases: the Bureau of Labor Statistics for CPI, the Bureau of Economic Analysis for GDP.

For rate decisions, the Federal Reserve's own announcement is the source. For elections, the source of the resolution is the Associated Press calling the race, not the official certification of the results.

For entertainment awards like the Oscars or the Emmys, resolution occurs when the awarding body makes the official announcement.

That distinction between “AP call” and “official certification” matters more than you'd think. On election night, a contract can resolve hours before a state formally certifies its results.

If you understand that going in, you know exactly when to expect your position to settle, and you're not sitting around waiting for something that already happened.

What Happens When an Event Is Postponed or Canceled

Edge cases are worth knowing about, too. If an event gets postponed or canceled, Kalshi's market rules specify how resolution works in those scenarios.

For entertainment markets, a delayed Oscar ceremony doesn't mean the contract expires worthless. It means the resolution waits for the rescheduled event. Reading the resolution criteria before you enter a position takes about 30 seconds and saves a lot of confusion later.

Polymarket uses a slightly different approach, with resolution sources specified per market and a community-based dispute process for ambiguous outcomes.

For political markets, the resolution logic tends to be straightforward. For more unusual markets, it's worth checking the details before you put money down.

What Moves Prices on Prediction Markets

Sports markets move on game events. Real-world markets move on information, and the information cycle varies by category.

Political Markets

On political markets, the biggest price movers are polling releases, fundraising reports, and major news events. A single high-quality poll showing a candidate up five points in a swing state will move a market faster than almost anything else.

Prices also react to what's happening on competing platforms. If Polymarket and Kalshi are pricing the same contract differently, arbitrage traders push them toward each other, which means a sudden move on one platform is often a signal worth paying attention to on the other.

Economic Markets

Economic markets run on a calendar. The Fed announces rate decisions on specific dates. CPI prints on a specific Tuesday every month. GDP estimates come out quarterly.

Unlike sports, where the action is live and unpredictable, most economic markets have a known resolution date weeks in advance. Positioning before a data release tends to be where the value is. Once the number hits, prices adjust fast, and the easy money is gone.

Culture and Entertainment Markets

Culture markets move differently again. Award show contracts have a precursor circuit that functions almost like a forecasting ladder. Critics' Choice typically comes before BAFTA, BAFTA before the Oscars, and the earlier results carry a real signal.

I've watched Oscar Best Picture contracts move meaningfully after BAFTA results landed, even though the two organizations vote independently. If you're trading entertainment markets, tracking the precursor season is probably the single most useful thing you can do.

Crypto Markets

Crypto markets on prediction platforms move with the underlying crypto markets, plus a layer of platform-specific mechanics around resolution dates and price targets.

A broader Bitcoin rally doesn't automatically resolve a contract. What matters is whether the price hits the specific target at the specific time the contract resolves. Those are different questions, and confusing them is a common mistake for new traders.

How to Choose the Best Prediction Market Site

I use six criteria to rank the best prediction market apps.

Market Selection

Market selection should be the first filter. There's no reason to use a prediction market app that doesn't cover the topics you want to trade.

For politics, Kalshi and Polymarket are the first two places I'd check. Polymarket US has a smaller menu right now, but its political markets are active and price news quickly.

Kalshi is the better pick if you want the widest range in one account. It covers politics, economics, culture, climate, companies, and plenty of smaller categories that most competitors don't touch.

OG and Crypto.com make more sense if you want to trade on culture and company markets. They won't match Kalshi's full range, but they're strong for music, gaming, AI, IPOs, and company headlines.

Fees

The difference between platforms can look small on one trade, but it starts to matter once you're placing a lot of orders.

Polymarket offers patient traders the best fee deal. If you use maker orders, you can post the price you want and earn a small rebate when another trader takes it. Kalshi offers more favorable fees for traders who make limit orders.

OG and Crypto.com keep fees simple with a flat $0.02 per contract. That's easy to understand, but it won't always be the cheapest option depending on the contract price and how often you trade.

Liquidity

Liquidity is easy to overlook until you try to enter or exit a market and the price you want isn't really there.

When a market has thin liquidity, buyers and sellers are usually far apart on price. That means you may have to pay more to enter a position or accept less when you want to get out.

It can be even more frustrating in fast-moving markets. If news hits and you want to close a position, there may not be enough money waiting on the other side at a fair price.

Kalshi and Polymarket usually have the strongest liquidity for political and economic contracts. OG and Crypto.com can have weaker liquidity once you move outside their main categories.

Welcome Bonus

When this market was finding its feet, plenty of prediction apps launched with no sign-up offer at all. That has flipped. Nearly every major platform now puts a welcome bonus on the table, so I treat it as one of my core scoring criteria.

A few different bonus structures are out there, and you can see the full breakdown in my prediction market bonuses guide.

The most common type of sign-up offer you can find at prediction markets is the trade-and-get, where the app credits you once you place a qualifying trade, which is the model that Kalshi, OG, and ProphetX run with.

A handful go the deposit-and-get route instead, handing you the bonus when you fund the account, like Polymarket and Novig.

Bonus size drives most of my score on a signup offer. Prediction markets don't attach wagering requirements to their bonuses, so a bigger offer generally means more usable value. That's not to say that the conditions are irrelevant. Short time limits, high qualifying trades, and low caps can each cut into an offer's value.

User Experience

User experience may sound irrelevant, but it affects how you trade.

Real-world events usually ask you to track a few things at once. You need to know how the contract resolves, where the price has been, whether another app has a better number, and when the next poll, earnings call, rate decision, or data release is coming.

A good interface makes all of that easier to check before you trade. A bad one makes you hunt for basic information while the price is moving.

OG will feel familiar if you're from sports betting, as it supports American odds.

Kalshi and Polymarket both give you order book visibility, which helps before you enter a position. You can see where buyers and sellers are priced, then decide whether to take the current number or wait for a better entry.

Banking

Payment options won't change how every market trades, but they matter when you need to fund quickly or cash out without extra friction.

Crypto.com is the best match if you use crypto. It supports 350+ cryptocurrencies, giving it the broadest crypto funding menu in the group.

Kalshi and OG make more sense if you prefer PayPal or Venmo. Both support those options, which is useful if you don't want to rely on bank transfers or crypto.

Polymarket is the strongest pick for higher-volume traders who care about banking costs. It has no deposit or withdrawal fees and offers high daily limits, making it easier to move larger amounts.

Tips for Trading on Prediction Markets

• Read the resolution rules before you enter. Resolution rules are especially important for real-world events. A political market based on an AP race call can settle differently from one based on official certification. An economic market tied to a BLS release settles on a specific number, date, and time. Spend 30 seconds on the rules before you trade, and settlement will be a lot less confusing.
• Use the economic calendar. CPI, Fed decisions, GDP, and jobs reports all have release dates that you can see weeks in advance. The best price is often available before the number drops. Once the report is out, the market usually reprices quickly, and you may be chasing a move other traders already caught.
• For award markets, follow the precursor awards. Critics' Choice, SAG, and BAFTA all happen before the Oscars, and each one can shift the race. If a movie keeps winning precursor awards but is still trading cheaply in a Best Picture market, I'm at least taking a closer look. Some smaller award markets don't always adjust quickly.
• Compare prices before you trade. The same political outcome can trade a few percentage points apart on Kalshi and Polymarket. On a meaningful position size, a better entry can save real money. Checking both platforms usually takes less than a minute.
• Be careful with long-dated markets. A year-end contract gives you time to change your mind and exit if your read changes. It also gives the market plenty of time to move against you. I treat longer-dated entries as a starting point, not a promise to hold until settlement.
• Use limit orders instead of taking the price in front of you. Posting a limit order makes you a maker, which means lower fees and, on some platforms, a rebate paid back to you. Taking the current price costs the most, especially in a market trading near 50 cents where fees peak. If you're patient and your read isn't time-sensitive, set your number and let the market come to you.
• Lean on Prediction Markets Pro for mentions and politics markets. Prediction Markets Pro tracks the data that drives contracts in politics markets from mention counts and speech patterns to polling shifts, and it saves you from manually counting how many times a politician says a word. For mentions markets in particular, where a contract can hinge on a single phrase in a single speech, having that history in front of you is the difference between a guess and a read.
• Check the order book before you size up. A price means nothing if there's no volume behind it. I've seen contracts showing a tempting number with only a handful of shares available at that level, which means a decent-sized order would move the price against you on the way in. Look at what's actually resting on both sides before you commit real money.
• Don't confuse a price with a probability you agree with. A contract at 60 cents means the market thinks the outcome happens 60% of the time. Your job isn't to pick winners; it's to find contracts where you believe the true odds differ from the price. If you'd bet on something at any price, you're not trading, you're just rooting.
• Trade the resolution date, not just the outcome. Two contracts can ask the same question with different deadlines, and the shorter window is almost always the harder bet. A market asking whether Bitcoin hits $150K by Friday is a different animal from one asking by year-end, even though the headline reads the same. Match the timeframe to how confident you are, not just how confident you are in the outcome.
• Sell early instead of holding to settlement. You don't have to ride a contract to $1 or $0. If your position moves from 40 cents to 70 cents on news, you can cash out the gain right there and free up capital for the next trade. Holding for the last 30 cents means carrying full risk for a shrinking reward, which is rarely the smart play.
• Watch for correlated contracts across a single event. A market on a Fed cut and one on a recession by year-end aren't independent, and neither are separate contracts on the same election. If you load up on several positions that all depend on the same thing happening, you don't have a diversified book. You have one big trade wearing a disguise.
• Fade the overpriced longshot. Prediction markets have the same favorite-longshot bias as sportsbooks, where 3-cent contracts on dramatic outcomes tend to trade above their true odds because people love a lottery ticket. Selling a longshot you think is overpriced is often better value than buying the favorite on the other side.

Prediction Markets FAQs

What is the best prediction market for politics, economics, and culture?
Kalshi covers the most ground across politics, economics, culture, crypto, commodities, and climate. For the lowest fees on political trading specifically, Polymarket is the better call. For culture and companies with a parlay builder and sportsbook-style interface, OG is worth a look.

How old do you have to be to use prediction markets?
You must be 18 or older to trade on Kalshi, Polymarket, and most other US prediction markets. That's a lower bar than sports betting, which requires you to be 21 in most states.

Are prediction markets safe and legal?
Yes. The major US platforms operate under CFTC regulation, which means federal oversight rather than state gaming licenses. Your funds are held in segregated accounts, and every contract is fully collateralized, so you can never lose more than you put in.

What is the difference between a prediction market and a sportsbook?
At a prediction market, you're trading contracts directly against other users with no house setting the line. Prices move with supply and demand, and you can exit before settlement if there's liquidity on the other side. At a sportsbook, the house sets the odds and builds a margin into every line, and your bet is fixed once you place it. You can check my guide on how prediction markets work to learn more about these platforms. 

Can you exit a position early?
On most prediction market apps you can, including Kalshi, OG, Crypto.com, and Polymarket. You can sell contracts before settlement as long as there's liquidity on the other side. That means you can lock in a profit if prices move in your favor, or cut a loss before the market fully resolves.

Are prediction market apps available across the US?
Kalshi and OG are available in most US states. Availability varies by platform, so always check the current terms for your state before depositing.

Can you use more than one prediction market at the same time?
Yes, and you should. The same contract can trade at different prices across platforms, so keeping accounts on two or three lets you shop for a better entry. It also gives you a backup when liquidity dries up on one of them.

Can you trade live during a game or event?
Yes. Kalshi, Polymarket, and most major platforms offer live trading on in-progress sports events, with prices updating in real time as the action unfolds. It works the same way on real-world markets, so a political contract will move the moment a result gets called.

How do prediction markets make money if there's no vig?
They charge trading fees instead of building a margin into the price.

Do you pay taxes on prediction market winnings?
Yes. Profits from CFTC-regulated prediction markets are generally taxable income in the US, and platforms don't withhold automatically. Most make tax documents available in your account settings at year-end.
