The Rise of Prediction Markets: How Polymarket, Kalshi, and PredictIt Monetize Our Beliefs
Not everyone is addicted to gambling, but those who do are always on the lookout for new opportunities to invest their money. There is a universal truth: if you can bet on the outcome of an event, there will definitely be those who want to take a risk. It is this feature of human nature that has opened the door to prediction markets, giving the industry such high-profile projects as Polymarket, Kalshi and PredictIt.
In an incredibly short period of time, prediction markets have gone from being a niche pastime to being the most important financial tool. According to analysts published by Reuters, in 2025, the trading volume of operators of such platforms reached $47 billion. This proves that the habit of "betting on one's beliefs" has become a serious part of the information economy. However, this growth has attracted the attention of regulators: in February 2026, the Commodity Futures Trading Commission (CFTC) issued a special warning regarding fraud and the use of insider information on forecasting platforms.
What makes this sector really interesting is the lack of monopoly. The market is divided between three conceptually different players: Polymarket functions as a crypto-native platform, Kalshi has transferred predictions to the format of an officially regulated exchange, and PredictIt remains the main laboratory for political forecasts. They all sell probabilities, but they package this product in completely different ways.
What are prediction markets?
At their core, these are platforms where people trade the outcomes of future events. Contracts are tied to real facts: election results, economic indicators (e.g. inflation), sports matches or even weather conditions. Traders buy and sell shares based on their expectations.
In the simplest binary case, buying a Yes contract for 30 cents means that the hive mind estimates the probability of the event at 30%. If the forecast comes true, the contract closes at $1; If not, it depreciates to zero. Thus, forecasting comes down to the pure trading essence: belief, price, payout.
Economists have long been interested in such markets because they are built on the right allocation of incentives. A study by the National Bureau of Economic Research (NBER) found that prediction markets integrate new information at lightning speed, provide little room for arbitrage, and are generally more accurate than surveys or professional analysts. As the event date approaches and more data becomes available, the percentage of errors in forecasts steadily decreases. This is not a magic crystal ball, but a continuous consensus mechanism where participants risk real money.
Of course, the system is not perfect. Low liquidity can distort prices, and vague contract wording can cause settlement chaos. Traders can succumb to emotions, and regulators are justifiably wary of insider trading and manipulation. However, with clear rules and liquidity, prediction markets become the best tool for measuring what informed people actually believe, rather than what they say out loud.
Polymarket: A Crypto-Native Forecasting Engine
Polymarket is the most "Internet" platform of the three. It combines the mechanics of predictions with blockchain technologies and on-chain settlements. The platform works as a peer-to-peer marketplace, uses smart contracts on the Polygon network and an oracle system to record the results.
The main trump cards of Polymarket are speed and breadth of coverage. The platform instantly reacts to trends: elections, geopolitics, sports, crypto, and breaking news, catching the mood of the crowd in real time. The scale speaks for itself: as of April 2026, the platform offered 10,798 active markets and had a trading volume of over $3.8 billion. At the same time, it has a complex system of commissions that are maximum in the middle of the price range and decrease as the probability approaches extreme values. It is also important to note the history of the project: after the CFTC sanctions in 2022, the platform returned to the United States in legal status thanks to the purchase of the regulated company QCEX. It's basically where Web3 meets the question "What are the odds?".
Kalshi: A regulated exchange with an institutional approach
Kalshi is strikingly different from competitors with its legal structure. It is an officially recognised Designated Contract Market (DCM) regulated by the CFTC, giving the platform an unmatched level of legal legitimacy. Kalshi is not trying to be an "alternative" platform, it positions itself as a serious exchange product.
The mechanics are familiar: contracts are traded from 1 to 99 cents and are calculated according to the "$1 or $0" principle. The platform is growing at a tremendous pace: according to Reuters, by the end of 2025, the weekly trading volume on Kalshi exceeded $1 billion. The company itself claimed millions of weekly users and more than 3500 available markets. Kalshi is constantly introducing new exchange features, such as incentives for liquidity providers and combined positions. The platform brings exchange discipline to the forecasting industry: transparency, market surveillance, and legal sustainability. Victories in the courts and the support of federal bodies only strengthened her position. If Polymarket is the pulse of the Internet, then Kalshi is forecast markets that have put on a business suit.
PredictIt: A Political Specialist with a Loyal Audience
PredictIt has consciously chosen a narrow specialisation and focused exclusively on politics. There is no such variety of topics as on Polymarket, or the institutional ambitions of Kalshi, but it is the main platform for forecasts for elections, appointments and laws. At the same time, the rules prohibit the creation of markets associated with wars, terrorist acts or murders.
The current model of the site's work was formed after receiving a letter from the CFTC in 2025. Operational management was transferred to the Consortium of Prediction Market Researchers (PMRC), the limit of 5,000 traders was abolished, and the maximum investment amount per contract was equated to the limit of donations to federal campaigns - $3,500. The main pain of PredictIt traders is high fees: the platform takes 10% of the profit and another 5% when withdrawing funds. Despite this, the platform remains highly sought-after due to its niche nature. For those who care more about the distribution of seats in the Senate than macroeconomics, this is the perfect tool. This is not a supermarket of forecasts, but a specialised political bureau.
Platform Comparison
Although all three platforms allow you to make money on future events, they have different strategies:
- Polymarket: The main advantage is the speed, variety, and native liquidity of the Internet. Previously, it faced complaints from the US authorities, but now has a regulated division.
- Kalshi: The main advantage is status, structure, and institutional trust. Fully regulated by the CFTC. The best choice for users who value legality and a traditional exchange format.
- PredictIt: The main advantage is a deep focus on politics and elections. It operates under the auspices of a research consortium and the supervision of the CFTC. It is designed for traders interested in political analytics.
The conclusion is obvious: Polymarket relies on scale, Kalshi on regulation, and PredictIt on specialisation.
Previously, the phrase "monitor the situation" meant passively reading the news. Prediction markets have turned this process into an active action that can be measured in money. Instead of just arguing in chat rooms, platform users monetise their hunches, proving that modern analytics is the ability to value in dollars what the crowd believes.Jessica Moore is a blog writer at CasinosInCanada who creates informative articles about online casinos and gaming trends.
Oh cool, prediction markets. Because what the world really needed was a way to parlay every political crisis and natural disaster into a fun little ‘yes or no’ bet for profit. But hey, if everything is already monetized, might as well slap a price on our beliefs too and call it ‘truth discovery’ instead of glorified gambling, right?
Again, these tales about "institutionals". The Polymarket is dragging, everything else is for the grandfathers from Wall Street! On the results of the Oscar, I raised the normal cash there, while Kalshi is being verified for six months. Blockchain rules
