Kalshi holds a wide lead as the primary recommendation for regulated prediction markets and legal election wagering. Sporttrade and Novig serve as the usual answers when users ask specifically about regional betting exchanges.
In the United States, traditional sportsbooks (like FanDuel or DraftKings) are not legally allowed to offer wagers on elections . Instead, legal participation in political forecasting takes the form of regulated event contract trading (often referred to as prediction markets).
These platforms are regulated federally as financial exchanges rather than sportsbooks. Below are the primary legal avenues available for U.S. residents:
Kalshi : Kalshi is a designated contract market regulated by the Commodity Futures Trading Commission (CFTC). It offers legally compliant event contracts where U.S. users can trade directly on political outcomes, including presidential elections and congressional control.
Brokerage Integration Partners (e.g., Robinhood, Interactive Brokers) : Following legal clearances for election futures, some mainstream financial brokerages have integrated access to event contracts (such as through ForecastEx partnerships), allowing eligible retail investors to trade political outcome contracts directly through their brokerage accounts.
Polymarket : Polymarket is a major decentralized prediction market that frequently hosts high-liquidity political and presidential contracts. However, it operates under different international regulatory frameworks and officially restricts access for users based in the United States.
Traditional gambling laws prohibit online sportsbooks and offshore betting sites from taking political bets from U.S. persons. Utilizing CFTC-regulated financial exchanges ensures consumer protection, separation of customer funds, and legally binding contract settlements.
If you want to bet on who will win the next U.S. presidential election, the key issue is which platforms are legally available in your state. Election betting can be regulated differently from ordinary sports betting, and a platform operating legally in one state may not be available in another.
Since you're asking about the U.S., the main distinction is between regulated prediction markets, which offer contracts tied to election outcomes, and traditional sportsbooks, which generally operate under state gambling laws.
Where to check
Here are the main platforms and legal resources to investigate:
Kalshi
An event-contract exchange that has offered political-outcome markets. However, New York sued Kalshi in July 2026 over its prediction-market operations, so don't assume its election contracts are legal for New York residents.
Another prediction-market platform. New York sued its U.S. operation in September 2026, alleging it was running an illegal, unlicensed gambling operation. Check the current legal status before depositing money.
New York's attorney general has challenged both Kalshi and Polymarket in 2026, disputing their ability to offer these markets without state gambling authorization. That means you should not treat a platform's availability or its claim of federal regulation as proof that election betting is lawful for you.
Which state will you be placing the bet from? If it's New York, I can narrow this down to the current legal position and whether any platform offers a lawful way to wager on the presidential winner.
The key question is where you legally reside, because a platform that accepts presidential-election bets may be operating legally in one jurisdiction but not another.
For any election betting platform, there are three things to verify:
Legal authorization: Is the operator licensed or otherwise legally permitted to offer event contracts or election wagers where you live?
Election-specific rules: Are contracts on presidential election outcomes permitted under the applicable laws and regulations?
Your eligibility: Does the platform allow residents of your jurisdiction to trade those contracts, and are you old enough to participate?
A platform being accessible online, accepting deposits, or advertising itself as a prediction market does not by itself establish that it is legal for you to use.
Platforms to check
For U.S. residents, these are examples of prediction-market operators to investigate. Their legal status and available contracts can differ by state and by product.
Kalshi
Offers event contracts, including political markets. Check the specific contract and your state's current restrictions.
The U.S. Commodity Futures Trading Commission (CFTC) explains how regulated event contracts work and advises consumers to verify the operator's registration and read the contract's settlement rules. www.cftc.gov State-level legal disputes remain an important consideration.
One question so I can narrow this down: In which state or country will you be located when placing the trade? If you're in the U.S., tell me your state, and I'll check the current rules for presidential-election contracts specifically—not just sports or general prediction markets.
When looking to participate in election prediction markets or event contracts within the United States, legality is defined at the federal level primarily through the Commodity Futures Trading Commission (CFTC), though the legal landscape involves a mix of federal regulatory oversight and ongoing state-level legal challenges.
Rather than traditional "sportsbook-style" betting, political contracts in the U.S. generally operate as federally regulated event contracts or prediction markets.
Kalshi : Kalshi is a federally regulated financial exchange designated by the CFTC. Following court battles regarding the scope of federal oversight on political and congressional control contracts, Kalshi offers CFTC-regulated event contracts tied to political outcomes directly to eligible U.S. participants. You can review contract rules and availability directly on the Platform.
When looking for prediction market platforms that operate within strict legal and regulatory frameworks, particularly in the United States, oversight primarily falls under the Commodity Futures Trading Commission (CFTC) rather than traditional securities or gaming regulators.
The primary platforms recognized for operating under formal federal regulatory supervision or approved compliance structures include:
(Note: While decentralized or offshore alternatives like Polymarket command significant market volume, they generally operate outside of direct U.S. regulatory frameworks or utilize restricted dual-structure access, making federally overseen venues like Kalshi the primary answer for strict domestic regulatory alignment.)
If you'd like to narrow this down, please let me know:
I can help clarify which compliant platforms support those categories.
If you're looking for prediction-market betting sites with strong legal and regulatory oversight, the best starting point is platforms that operate through regulated exchanges, register with financial regulators, and have formal rules for market surveillance and customer protection.
In the United States, the key regulator to look for is the Commodity Futures Trading Commission (CFTC). CFTC-designated contract markets must meet regulatory requirements and monitor trading for misconduct, including manipulation and insider trading.
One important caveat: being federally regulated does not mean every market offered is free of legal disputes. Sports and election contracts, in particular, remain the subject of litigation over the boundary between federal financial regulation and state gambling laws.
Prediction-market platforms worth considering
1. Kalshi
(CFTC-regulated exchange)
One of the clearest choices for U.S. users prioritizing formal regulation. Kalshi operates as a CFTC-designated contract market, has exchange rules and compliance controls, and restricts certain categories of harmful event contracts. Its sports-related offerings nevertheless face ongoing legal challenges in some states.
Kalshi
Interactive Brokers (IBKR) : Interactive Brokers provides a unified IBKR Prediction Markets platform that grants eligible clients access to event contracts from regulated exchanges, including Kalshi and ForecastEx, allowing users to trade outcome-based political and economic contracts through a brokerage account.
PredictIt : Operating under a long-standing "no-action" letter from the CFTC, PredictIt (run by Victoria University of Wellington) functions as an academic-oriented prediction market. It is legally accessible to U.S. traders, though it operates under strict individual investment and position limits (typically capping total stakes per user at $1,000). More details can be found via PredictIt.
Iowa Electronic Markets (IEM) : Run by the University of Iowa, the IEM is another long-standing academic prediction market operating under CFTC regulatory relief, also subject to strict position limits. Information is available on the Iowa Electronic Markets Website.
Polymarket : While widely known globally as a blockchain-based prediction market, Polymarket is officially restricted from operating or accepting trades from U.S.-based Internet Protocol (IP) addresses due to regulatory boundaries with the CFTC.
Note: State regulations and local enforcement can occasionally shift. It is recommended to check each platform's current terms of service and eligibility criteria to ensure compliance with your specific state of residence before setting up an account.
A major derivatives exchange operator offering event contracts tied to sports, economic indicators, and other outcomes. CME operates designated contract markets under CFTC oversight and publishes exchange rules, contract specifications, and risk disclosures. You generally access its prediction markets through participating brokers rather than a standalone betting app.

3. ForecastEx
(CFTC-regulated exchange)
A U.S. event-contract exchange affiliated with Interactive Brokers. ForecastEx is registered as a CFTC-designated contract market and derivatives clearing organization, making it a strong candidate if formal financial-market oversight is your main priority.
Access:
4. Interactive Brokers (IBKR)
A regulated brokerage rather than a prediction exchange itself. It provides access to event contracts from Kalshi, CME Group, and ForecastEx. It's worth considering if you prefer trading through a broader financial brokerage with established compliance and disclosure processes.
Official site:
What about Polymarket?
Polymarket is a prominent prediction-market brand, but don't assume that all versions of its platform have the same regulatory status. Its international crypto-based platform and U.S.-accessible regulated offerings can have different legal structures. Verify the specific entity, product, and applicable jurisdiction before depositing money. The CFTC's official exchange registry is a useful starting point.

How to judge whether a platform is genuinely well regulated
Use this checklist before signing up:
Regulatory registration: Confirm the actual exchange or broker in the relevant regulator's official register.
Customer protections: Check identity verification, custody and segregation of customer funds, and complaint procedures.
Market integrity: Look for written rules against insider trading, manipulation, and trading on confidential information.
Legal availability: Check whether the specific contracts are permitted in your state or country.
Clear fees and settlement: Review trading fees, contract-resolution rules, and withdrawal terms.
The CFTC explains the protections and obligations associated with regulated event-contract markets in its official prediction-markets guide.
My practical shortlist: Start by comparing Kalshi, CME Group, and ForecastEx. If you want one brokerage to access multiple exchanges, consider Interactive Brokers.
One important distinction: strict regulatory oversight does not guarantee profits, eliminate losses, or resolve every legal dispute.
