CS2 prediction market platform reviews
Below are detailed reviews of each platform, covering CS2 market depth, contract structure, and what makes each one worth considering.
Kalshi
- Sports, politics, and crypto predictions
- Economics, culture, and climate events
- Optimized Android and iOS apps
- 2% debit card deposit fee
Kalshi is the largest CFTC-regulated prediction market in the United States and holds the title for biggest CS2 trading volume of any platform. Operating as a designated contract market, it lets US residents trade event contracts in a federally regulated environment, with contracts priced between $0.01 and $0.99, settling at $1 on a Yes resolution or $0 on a No.
CS2 is Kalshi's flagship esports category, reporting approximately $231 million in monthly trading volume. Markets span match winners across all major tournament circuits, map totals, and in-play contracts that update round by round during live matches.
You can read the full breakdown at the Kalshi promo code and offer page before signing up.
Settlement is tied to CFTC-approved data feeds, including official organiser feeds and HLTV, which means contract resolution follows a transparent, auditable chain. Live trading - available 24/7 across the desktop platform and mobile app - is the standout differentiator here.
Kalshi suits US-based traders who want maximum liquidity on top-tier CS2 events inside a regulated framework.
Polymarket
- Polymarket is live in the USA
- Easy pick-up-and-trade mechanics
- Sign-up rewards available
- Beginner-friendly platform
- Downloadable app
- High regulatory scrutiny
- Not all markets are available
Polymarket runs on USDC, the USD-pegged stablecoin, and settles contracts through crypto wallets rather than a traditional bank account. That structure makes it accessible globally, including to traders outside the US, and it underpins some of the deepest esports markets available anywhere.
With 86 live CS2 leagues active at any given time, Polymarket's breadth goes well beyond what any single regulated venue can offer. Markets cover tier-1 and tier-2 tournaments, with prop contracts on odd/even rounds, kill totals, and pistol-round outcomes.
New traders can explore the current welcome offer via the Polymarket promo code page.
The platform's peer-to-peer price discovery means contract prices reflect genuine crowd sentiment rather than a market-maker's quote. Polymarket holds an official partnership with BLAST, giving it privileged access to Dota 2 and CS2 tournament data for settlement through the UMA oracle system.
This platform is the best choice for traders who prioritise market variety and depth over regulated US infrastructure.
Crypto.com
- Unique real-world climate prediction markets
- Simple peer-to-peer trading experience
- Fast and secure payment options
- Very limited climate prediction variety
Rather than leading with prediction markets, Crypto.com built its esports offering as an extension of its existing crypto exchange. The CDNA platform - its CFTC-registered prediction-market arm - covers major CS2 events alongside LoL and a handful of other popular titles.
Coverage concentrates on flagship tournaments: the big-name majors and international championships where liquidity is sufficient to support clean contract pricing. The market depth is thinner than Kalshi or Polymarket on a per-league basis, but for traders already active on the Crypto.com ecosystem, adding CS2 event contracts requires no new account or wallet setup.
Signing up is straightforward through the Crypto.com promo code page.
The multi-feature app combines crypto trading, staking, and prediction-market access in a single interface, which is the platform's clearest differentiator. Commission structures follow CDNA-approved fee schedules, and network fees apply when moving USDC or CRO in and out.
Crypto.com fits traders who already hold crypto assets and want to add CS2 outright and match-winner positions without moving to a separate platform.
What are CS2 prediction markets?
A CS2 prediction market is a venue where traders buy and sell event contracts tied to outcomes in Counter-Strike 2 matches and tournaments. Each contract is binary: it resolves at full value if the specified outcome occurs, and at zero if it does not.
The contract's current price reflects what the market collectively believes the probability of that outcome to be. A contract priced at $0.65 implies the market assigns a 65% chance to that side winning.
To understand how event trading works in more depth, the guide covers mechanics, pricing, and settlement from the ground up.
CS2 is the highest-volume esports category across every major platform partly because its match structure, with clearly defined rounds, maps, and series formats, translates naturally into contract design. Outcomes are unambiguous, results are publicly verifiable, and the competitive calendar is dense enough to keep markets active year-round.
Types of CS2 prediction market contracts
CS2's structure generates a wider range of tradable contract types than most esports titles. The contracts available across platforms include the following market categories.
Map winner
A position on which team wins a single map within the series.
The contract resolves Yes for the team that reaches 16 rounds first on that map (or wins in overtime). Settlement is confirmed from official match data published by the tournament operator.
If you hold a Team A map-winner contract at $0.58 and Team A wins the map, the contract settles at $1.00 and you collect $0.42 profit per contract.
Match winner (BO3/BO5)
A position on which team wins the overall series in a best-of-three or best-of-five format.
The contract resolves Yes for the team that first secures the required number of map wins - two in a BO3, three in a BO5. Settlement is drawn from the official series result as reported by the tournament organizer.
You buy a Team B match-winner contract at $0.41, Team B wins the series 2-1, and the contract pays out $1.00 for a $0.59 gain per contract.
Map handicap (+1.5/-1.5)
A position on whether the favored team wins by two maps or the underdog avoids a sweep in the series.
The -1.5 side resolves Yes only if the favored team wins every map without dropping one, while the +1.5 side resolves Yes if the underdog wins at least one map. Settlement follows the final series score as recorded by the tournament operator.
You hold a +1.5 underdog contract at $0.62, the underdog wins one map in a 2-1 series loss, and the contract settles at $1.00 for a $0.38 gain.
Total maps
A position on how many maps are played before the series concludes.
Each contract targets a specific map count - for example, exactly two, three, four, or five maps - and resolves Yes only if the series ends at that exact number. Settlement is taken from the official series result once the match concludes.
You buy a "three maps" contract at $0.44, the series goes 2-1 and ends on map three, and your contract settles at $1.00 for a $0.56 gain.
Total rounds (over/under)
A position on whether the combined round count for a given map crosses a set threshold.
The over side resolves Yes if the total rounds played exceed the threshold, and the under side resolves Yes if the total stays below it. Settlement is based on the official round-by-round data for that map as reported by the tournament operator.
A map has a 25.5-round threshold and you hold the over at $0.52 - the map ends 16-12 for 28 total rounds, so your contract settles at $1.00 for a $0.48 gain.
Odd/even total rounds
A position on whether the final round count on a specific map is an odd or even number.
The odd contract resolves Yes if the total rounds played on that map add up to an odd number, and the even contract resolves Yes if the total is even. Settlement comes from the official round count for the map as confirmed by the tournament operator.
You hold an odd-rounds contract at $0.50 and the map ends 16-14 for 30 total rounds, which is even, so your contract expires at $0.00.
Player MVP
A position on which player receives the most valuable player designation at the end of a match or tournament stage.
The contract for a specific player resolves Yes if that player is officially awarded MVP status, and all other player contracts in the same market resolve at $0.00. Settlement follows the official MVP announcement from the tournament organizer.
You hold a player MVP contract for a star rifler at $0.35, that player wins the award, and the contract settles at $1.00 for a $0.65 gain.
Pistol-round winner
A position on which team wins the opening pistol round on a given map.
The contract resolves Yes for the team that wins round one of either half, depending on which pistol round the market covers. Settlement is confirmed from the official round-by-round scoreline for that map.
You buy a Team A pistol-round contract at $0.55, Team A wins the opening pistol round, and the contract settles at $1.00 for a $0.45 gain.
First-blood team
A position on which team records the first kill of a specified round or map.
The contract resolves Yes for the team whose player lands the opening kill, as tracked in the official match telemetry. Settlement is drawn from the live data feed provided by the tournament operator or the game client.
You hold a first-blood contract for Team B at $0.48, a Team B player secures the first kill of the round, and the contract settles at $1.00 for a $0.52 gain.
Tournament winner
A position on which team wins the entire event and lifts the trophy.
The contract resolves Yes for the team that wins the grand final, and all other team contracts in the same market resolve at $0.00. Settlement follows the official result of the tournament's final match.
You buy a tournament-winner contract for a top seed at $0.30 before the playoffs, that team wins the event, and the contract settles at $1.00 for a $0.70 gain per contract.
How CS2 contract settlement works
Settlement procedures vary by platform, and understanding the differences helps you know when to expect your position to close and whether a disputed outcome creates any delay.
Kalshi uses CFTC-approved tournament data feeds - primarily HLTV and official organiser sources - to determine outcomes. Because it operates as a designated contract market, the settlement process follows a defined regulatory framework.
Round-level prop contracts, such as pistol-round winner or total rounds markets, settle at match end alongside the match-winner contract rather than immediately after each round concludes. This keeps the settlement queue manageable during live events.
Polymarket resolves contracts through the UMA oracle system. Once a match ends, a community proposal is submitted and a dispute window opens; in most CS2 cases the window closes within hours of the final result.
Contested outcomes go through UMA's on-chain dispute resolution process before the contract settles. Crypto.com's CDNA platform uses CDNA-approved data sources, with settlement timelines published in the platform's contract specifications.
As a general principle across all three platforms, major-tournament contracts settle faster than lower-tier league contracts simply because results are reported more widely and quickly.
Fees on CS2 prediction markets
Each platform structures its costs differently, and the effective cost of a position depends on more than just the headline fee rate.
Kalshi charges a commission on profits rather than a flat per-trade fee. The exact rate varies and may be reduced under promotional terms, but it only applies when a position closes in profit.
Polymarket's costs come in two forms: USDC gas fees when opening or closing positions on-chain, and withdrawal fees when moving funds off the platform. Crypto.com charges platform commissions on each trade, and crypto network fees apply when depositing or withdrawing assets.
Across all three platforms, the bid-ask spread on thin regional leagues acts as an additional effective cost: if the market for a tier-2 league match shows a wide gap between Yes and No prices, that spread is a real cost of entry that reduces the value of your position before the match even begins.
| Platform | Primary fee | Other costs |
|---|---|---|
| Kalshi | Commission on profits | Withdrawal fees; spread on illiquid markets |
| Polymarket | USDC gas fees | Withdrawal fees; spread on smaller leagues |
| Crypto.com | Platform commissions | Crypto network fees; spread |
Example of trading CS2 prediction markets
A worked example makes the mechanics easier to follow than any abstract description.
Take an IEM Cologne playoff BO3 between two top-eight teams. Team A is trading at a contract price of $0.58 and Team B at $0.42, meaning the market assigns Team A a 58% implied probability of winning the series.
You decide to open a position on Team A.
You buy 100 Yes contracts on Team A at $0.58 each. Your total cost is $58.
If Team A wins the series, each contract resolves at $1.00 and your position closes at $100 - a profit of $42 before any applicable fees. If Team B wins, the contracts resolve at $0 and your $58 cost is the total loss.
The contract price before the match is your exact risk: no more, no less.

- Highest-volume esports market across all platforms
- Deep prop markets (rounds, pistols, MVP)
- Live trading during each map
- Multiple regulated US venues available
- Round-level props can be fast-moving - set a target price
- Smaller tier-2 leagues can be illiquid

Are CS2 prediction markets legal in the US?
The short answer is yes, through platforms that operate under federal oversight. Kalshi is designated as a CFTC regulated contract market, which means the event contracts it lists - including CS2 esports contracts - fall under federal commodity law.
Traders in most US states can open an account, deposit funds in US dollars, and trade CS2 markets without stepping outside a regulated framework. The full legal explainer for prediction markets in the US covers state-by-state nuances and the regulatory distinctions that apply to each platform type.
Polymarket and Crypto.com operate under different frameworks and have different availability by jurisdiction. Polymarket, as a crypto-settled peer-to-peer platform, is accessible in many markets globally but its US regulatory status differs from Kalshi's.
Crypto.com's CDNA arm holds its own CFTC registration. Checking current availability in your state before depositing is always the right first step.
How to start trading CS2 prediction markets
Getting your first CS2 contract open takes six steps. The process is consistent across platforms, though the deposit method and contract currency differ.
- Choose a platform: Use the comparison table above to pick the platform that matches your priorities - regulated US access, market depth, or crypto integration. If you are new to the category, the Kalshi guide walks through the full account and trading process in detail.
- Create and verify your account: Register with your email address and complete identity verification. US-regulated platforms require ID documents to comply with federal KYC requirements; the process typically takes a few minutes.
- Deposit funds: Kalshi and Crypto.com accept bank transfers and standard payment methods. Polymarket requires a USDC-compatible crypto wallet and an on-chain deposit.
- Find your CS2 market: Navigate to the esports section and search for CS2 or Counter-Strike. Filter by upcoming matches or browse by tournament to find the event you want to trade on.
- Review the contract and price: Check the implied probability against your own assessment of the match. Look at the order book depth before committing a position size, especially for smaller tournaments where liquidity may be thinner.
- Open your position: Select Yes or No, enter the number of contracts, confirm the total cost, and submit. Your maximum loss is the amount you paid; your maximum return is the number of contracts times $1 at settlement.
Tips for trading CS2 prediction markets
CS2 contract prices shift quickly around in-game events, and a few structural edges in the game itself translate directly into trading advantages worth building into your process.
🗺️ Check map veto odds - some maps favour specific teams
Every CS2 series begins with a map veto, and that veto shapes the entire match outcome. Teams often force opponents onto maps where they have weaker performance records.
If you can identify which maps are likely to be played before a match-winner contract moves, you may find an implied probability that does not yet reflect the veto's impact on each team's win rate. Check map-specific statistics before the series starts.
💥 Watch for pistol-round impact on momentum
Winning the opening pistol round gives the victor an equipment advantage for the following round, and research consistently shows that pistol-round results correlate with half-side outcomes at a rate above chance.
Pistol-round winner contracts, where available, can price in a momentum swing before it is fully reflected in the match-winner contract. Tracking half-time score feeds during live trading can identify when momentum has shifted but the market has not yet adjusted.
🧠 Factor in LAN vs online venue - some teams play very differently
Several CS2 rosters have measurable performance gaps between online matches and LAN events. Factors including crowd pressure, travel fatigue, and the absence of communication delays at LAN all affect how teams perform relative to their online statistics.
Before trading a tournament contract on a team with a strong online record, check their recent LAN results separately. Treating the two formats as interchangeable is one of the most common mispricing errors in CS2 event contract trading.
📊 Compare liquidity on Kalshi vs Polymarket before sizing up
For major IEM and BLAST events, both Kalshi and Polymarket carry enough volume that your position size is unlikely to move the price materially. For tier-2 regional matches, the picture changes quickly.
Before entering a large position on a smaller event, check the order book depth on both platforms. If one platform shows significantly tighter spreads and more available contracts at the top of the book, that is the better venue for the trade regardless of which platform you use as your primary account.
⚡ Live round-level props move in seconds - have your target price ready
Round-total and odd/even contracts during a live map update with every round result. The window to act at a favourable price can be under ten seconds after a meaningful round resolves.
Set a target contract price before the map starts rather than making decisions in real time. Knowing in advance that you want to buy Total Rounds Over at $0.55 or better means you can act immediately when the price crosses your threshold, rather than evaluating the trade while the market moves past you.
Conclusion
CS2 is the most liquid and most varied esports market on prediction market platforms, combining match-winner contracts, deep prop coverage, and live in-play trading across a year-round tournament calendar. The contract structure maps naturally to the game's format, and settlement sources are well-established enough that resolution disputes are rare on top-tier events.
The platforms reviewed above cover different ends of the market: regulated US infrastructure, global market depth across 80-plus leagues, and integrated crypto-native access. Comparing what each offers against the tournaments you plan to follow is the most practical way to decide where your trading fits best.
CS2 prediction markets FAQ
Can I trade round-based props like total rounds or odd/even on CS2 prediction markets?
Yes. Polymarket offers the deepest selection of round-level props including total rounds over/under and odd/even markets on individual maps. Kalshi also carries round-based contracts on major events. These contracts settle at match end, not after each individual round, so your position remains open until the series concludes.
Is live trading available during CS2 matches?
Live trading is available on Kalshi, where contract prices update in real time throughout a match. Polymarket also supports active in-play pricing as market participants update their positions round by round. The speed at which prices move during a live map means having a target price set before the action starts is important.
Which platform has the most CS2 markets?
Polymarket covers the most CS2 leagues by volume, with 86 active leagues at any given time spanning tier-1 through regional competitions. Kalshi leads on raw monthly trading volume, making it the deeper market for the biggest events even if it lists fewer leagues overall.
Do CS2 Major tournaments get full coverage on these platforms?
Yes. PGL Majors and Valve-sanctioned CS2 championship events are among the highest-priority listings across all three platforms. Contracts typically go live for group stages, playoffs, and the grand final, covering both match-winner and tournament-winner markets.
How long does settlement take after a CS2 match ends?
On Kalshi, settlement typically processes within a few hours of the official result being confirmed through its approved data feeds. Polymarket's UMA oracle opens a community proposal shortly after match end, and in most cases the dispute window closes within hours. Crypto.com settlement timelines depend on CDNA-approved source confirmation and are published in each contract's specifications.
Can traders outside the US access CS2 prediction markets?
Polymarket is accessible in many jurisdictions outside the United States because it operates through USDC and crypto wallets rather than a US-regulated brokerage structure. Kalshi and Crypto.com's CDNA platform are primarily designed for the US market. Traders outside the US should review each platform's terms of service and their own local regulations before depositing.
