Kalshi And Polymarket Are Live: What US Traders Must Know Now
Prediction markets have existed in some form for centuries, but cryptocurrency changed something fundamental about them. For the first time, anyone with an internet connection can take a financial position on the outcome of a real-world event, from election results to interest rate decisions, without a broker, a bookie, or a bank standing in the middle. Two platforms sit at the center of this shift right now: Kalshi and Polymarket. Understanding how they work, how they differ, and where the legal lines sit in 2026 is no longer optional for serious cryptocurrency traders.
TL;DR
- Prediction markets let you buy and sell contracts tied to yes/no outcomes of real-world events, with your payout determined entirely by whether the event resolves in your favor.
- Kalshi is a federally regulated U.S. exchange operating under the CFTC, while Polymarket runs on-chain via the **Polygon** [(POL)](https://www.noncemedia.com/asset/pol) network and currently blocks U.S. IP addresses following a 2022 settlement.
- Before trading either platform, U.S. residents must understand the regulatory gap between them, how liquidity shapes pricing accuracy, and the tax treatment of event contract gains.
What Prediction Markets Explained Actually Means
A prediction market is a financial exchange where the assets being traded are contracts tied to future events rather than companies or currencies. Each contract pays out $1 (or the equivalent in stablecoins) if a specific outcome occurs, and zero if it does not. Traders buy and sell these contracts before the event resolves, and the market price at any moment represents the crowd’s collective probability estimate.
If a contract for “Federal Reserve cuts rates before September 30, 2026” trades at $0.62, the market is effectively pricing a 62% probability of that cut happening. When the event resolves, holders of the correct side receive $1 per contract. Holders of the wrong side receive nothing.
> “The price of a prediction market contract is a probability expressed in dollars. A contract trading at $0.70 means the market believes there is a 70% chance the event occurs.”
This structure makes prediction markets fundamentally different from sports betting or casino gambling, even though they can superficially resemble both. The pricing mechanism is continuous and reflects real information aggregation. Academic research, including work published by the Journal of Economic Perspectives, has repeatedly shown that prediction markets outperform polls and expert panels on forecasting accuracy because participants have a direct financial incentive to be correct, not merely opinionated.

How Kalshi Works As A CFTC-Regulated Exchange
Kalshi is a designated contract market licensed by the U.S. Commodity Futures Trading Commission (CFTC). That single fact separates it from every other prediction market operating in the English-speaking world. Kalshi received its DCM designation in November 2020, making it the first federally regulated event-contracts exchange in the United States.
Because Kalshi operates under federal oversight, U.S. residents can use it legally and without a VPN. Deposits and withdrawals run through standard U.S. bank rails in dollars. There is no native cryptocurrency involved in the trading experience itself, though the underlying mechanics share more with financial derivatives than with a traditional brokerage account.
Kalshi’s market catalog includes interest rate decisions, inflation readings, economic data releases, political events, and sports outcomes. In June 2026, the platform announced a $1,000,000 prize pool contest tied to the 2026 FIFA World Cup, a sign of how far the platform has moved toward mainstream engagement since its founding.
Kalshi’s regulatory status does come with trade-offs. Market creation is more restricted than on permissionless platforms. The CFTC must approve new market categories, which means fast-moving topics can take weeks to reach the order book. Fee structures are transparent and disclosed, but they are present on both sides of a trade.
> “Kalshi’s CFTC license is its core competitive advantage for U.S. traders and its core constraint for market variety.”

How Polymarket Works As An On-Chain Protocol
Polymarket is a decentralized prediction market built on the Polygon (MATIC) network. Traders use USD Coin (USDC) to buy outcome shares, and all positions, resolutions, and payouts are handled by smart contracts rather than a centralized counterparty. There is no Polymarket employee who decides whether a market resolves yes or no. An optimistic oracle system, currently powered by UMA Protocol, handles dispute resolution.
Polymarket’s permissionless structure means market creation is open and fast. During major political events, Polymarket’s election markets have generated hundreds of millions of dollars in volume within single weeks, making them among the most liquid public forecasting venues on the planet for those specific events. The 2024 U.S. presidential election cycle saw Polymarket briefly become a mainstream media reference point for probability tracking.
The legal situation for U.S. users is more complicated. In January 2022, Polymarket settled with the CFTC for $1.4 million and agreed to block U.S.-based users from the platform. The restriction is enforced via IP geolocation. U.S. residents who use a VPN to access Polymarket do so outside the bounds of the settlement terms, and the CFTC has indicated it views circumvention of such blocks seriously.
For non-U.S. traders, Polymarket offers a genuinely open, permissionless experience. Connecting a Web3 wallet, bridging USD Coin (USDC) to Polygon, and placing a position takes under ten minutes once the infrastructure is set up.

How Pricing And Liquidity Actually Work On Both Platforms
Prediction market contracts are priced between $0.01 and $0.99 before resolution. That price reflects the aggregated bids and asks from all active participants, the same way a stock price reflects supply and demand. Understanding what drives pricing accuracy helps traders spot mispricings.
Liquidity is the most important variable. A market with $50,000 in open interest will have a more accurate price than one with $500, because large participants cannot move the price without injecting real information or real capital. Polymarket’s larger user base and permissionless global access tend to generate deeper liquidity on high-profile political and economic markets. Kalshi’s regulated status draws institutional participants who may bring different information and larger position sizes.
Automated market makers (AMMs), which are smart contract-based liquidity pools that hold both outcome tokens, backstop thin markets on Polymarket when human counterparties are scarce. On Kalshi, a traditional central limit order book (CLOB) matches buyers and sellers directly, the model familiar from stock exchanges.
Traders should watch the bid-ask spread as a quick proxy for liquidity quality. A spread of $0.01 to $0.02 on a contract priced at $0.60 indicates a healthy market. A spread of $0.10 or wider on the same contract suggests thin liquidity and a higher cost of entry and exit. Entering wide-spread markets means you are already underwater by the size of the spread the moment your order fills.

Market Resolution And The Oracle Problem
Every prediction market lives or dies by its resolution mechanism. When the event occurs, something must determine the final payout. On centralized platforms like Kalshi, the exchange itself resolves markets based on publicly verifiable primary sources such as official government data releases or certified election results.
On decentralized platforms like Polymarket, the oracle problem becomes a design challenge. Oracles are systems that bring off-chain real-world data onto the blockchain. Polymarket’s UMA-based system uses an optimistic model: a proposed resolution is submitted, and a challenge window opens. If no one disputes it with a bond, the resolution stands. If someone disputes it, UMA token holders vote to arbitrate.
This system has worked well for clear-cut outcomes but has generated controversy on ambiguously worded markets. In 2024, several Polymarket markets related to political events produced heated disputes over whether the resolution criteria had been met, with some users losing positions they believed they had won on the underlying facts. The resolution wording of a market, not just its subject, is something every trader should read carefully before committing capital.
Kalshi’s centralized resolution is more predictable in practice, though it introduces a single point of trust. The CFTC oversight provides a formal dispute mechanism that on-chain governance does not.

Tax Treatment And Record-Keeping For U.S. Traders
U.S. traders on regulated prediction markets like Kalshi must treat gains as taxable income. The IRS has not issued formal guidance specifically tailored to event contracts as of June 2026, but the consensus among tax practitioners is that winnings from CFTC-regulated event contracts are treated as short-term capital gains or ordinary income, depending on how the instrument is classified.
Kalshi issues 1099 forms to U.S. account holders who meet the reporting threshold, which simplifies record-keeping relative to on-chain alternatives. Every trade, every resolution, and every withdrawal is logged against a verified identity.
On-chain platforms like Polymarket generate no tax forms. Every USDC transaction, every outcome token purchase, and every resolution payout is recorded permanently on the Polygon blockchain, however, and the IRS treats on-chain transactions as taxable events regardless of whether a form arrives. Tools such as Koinly and CoinTracker can import Polygon wallet history and generate cost-basis reports, but the trader bears full responsibility for accurate reporting.
Position sizing relative to tax liability matters more in prediction markets than in many other instruments. A $500 position that resolves at $1,000 (a 100% return) generates a $500 taxable gain. If that same market resolves at zero, the $500 loss may offset other gains. Tracking both outcomes is mandatory, not optional.

Who Should Actually Use Prediction Markets
Prediction markets are not suitable for every cryptocurrency participant, and being honest about that distinction matters. They are best suited to traders who have a specific, researched informational edge on a particular event, not to traders seeking broad market exposure or passive yield.
If you follow Federal Reserve communications closely and believe the market is mispricing the probability of a September 2026 rate cut, a Kalshi interest rate market gives you a direct, efficient way to express that view. The contract will resolve based on a binary outcome within a defined time horizon, and your maximum loss is capped at your position size.
If you are a casual cryptocurrency holder looking to grow your portfolio, prediction markets introduce a fundamentally different risk profile. Every position is a binary bet with a fixed expiry. There is no “holding through a dip” strategy, because contracts either resolve in your favor or they do not.
Researchers, analysts, and journalists increasingly use prediction market prices as data rather than as trading vehicles, treating the aggregated probabilities as a real-time polling mechanism with financial skin in the game. This is one of the most underappreciated use cases: reading the market, not entering it.
For non-U.S. participants, Polymarket’s permissionless model offers access to a wider range of markets with deeper liquidity on high-volume events. For U.S. participants, Kalshi is the only legally accessible regulated option, and its market catalog is meaningfully narrower but growing.

Conclusion
Prediction markets are one of the most intellectually coherent applications of the cryptocurrency infrastructure built over the past decade. They combine financial incentives with information aggregation, producing probability estimates that consistently outperform other forecasting methods in controlled studies.
For U.S. traders, the regulatory map is clear: Kalshi operates legally under CFTC oversight, accepts dollar deposits, and provides 1099 reporting. Polymarket offers a deeper, more permissionless global market but is off-limits to U.S.-based users under the terms of its 2022 CFTC settlement. Using a VPN to circumvent that block is a legal risk, not a technical workaround.
The most important skill in either venue is not picking winners. It is reading the resolution criteria of a contract carefully, assessing the liquidity depth before entering, and sizing positions relative to your total risk budget. Prediction markets reward precision, not enthusiasm, and that distinction separates the participants who profit from those who donate their capital to the order book.
