Prediction Markets Explained: How Event Contracts Are Reshaping Trading

Prediction markets have gone from a fringe experiment to a $44 billion annual volume sector in under two years. What started as niche political betting — mostly limited to academic circles and small-scale platforms — has exploded into a mainstream financial product category attracting Robinhood, Coinbase, Interactive Brokers, and dozens of other major platforms.

The concept is simple: instead of analyzing charts or reading earnings reports, you trade contracts on whether a real-world event will happen. Will the Federal Reserve cut rates at its next meeting? Will Bitcoin hit $150,000 by year-end? Will a specific team win the Super Bowl? Each question becomes a tradeable contract priced between $0 and $1, reflecting the market’s collective probability estimate for that outcome.

This guide explains how prediction markets work, which platforms dominate the space, how they are integrating into traditional brokerage infrastructure, and what the regulatory landscape looks like heading into 2026. Whether you are an active trader exploring a new asset class or simply curious about how event contracts function, this breakdown covers the essentials.

What are prediction markets?

A prediction market is a trading venue where participants buy and sell contracts based on the outcome of future events. Rather than trading an asset like a stock or currency pair, you trade a position on whether something will or will not happen.

Each contract is structured as a binary outcome. You can buy a “Yes” position (you believe the event will occur) or a “No” position (you believe it will not). Contracts are priced between $0.01 and $0.99, and this price represents the market’s implied probability. A “Yes” contract trading at $0.65 means the market collectively estimates a 65% chance that the event will occur.

If the event happens, “Yes” contracts pay out $1.00 and “No” contracts expire worthless. If the event does not happen, the reverse applies. The profit is the difference between what you paid and the $1.00 payout — or the full purchase price if you are wrong.

This structure is functionally similar to a binary option, which is a critical distinction in regulatory discussions. However, prediction markets differ in that they are tied to observable real-world events rather than financial instrument price movements, and they operate on regulated exchanges with transparent order books.

The concept is not new. The Iowa Electronic Markets, launched in 1988 at the University of Iowa, allowed small-scale trading on U.S. election outcomes for research purposes. But for decades, prediction markets remained confined to academic settings and low-volume platforms like PredictIt. The breakout came in 2024, when Polymarket surged during the U.S. presidential election cycle, and Kalshi secured a landmark legal victory affirming its right to list political event contracts.

By early 2026, the sector had matured far beyond elections. Prediction markets now cover economic indicators, sports, technology milestones, and cultural events — creating a new asset class that bridges traditional finance and real-world information.

How do prediction markets work?

The mechanics of prediction market trading follow a straightforward cycle: contract creation, trading, and settlement.

Contract creation begins when a platform lists a new event with clearly defined resolution criteria. For example, Kalshi might list a contract asking: “Will the Federal Reserve cut rates by 25 basis points at its March 2026 meeting?” The contract specifies exactly how the outcome will be determined (in this case, the official FOMC statement), the expiration date, and the settlement rules.

Trading works through an order book model on centralized platforms like Kalshi, which operates a Central Limit Order Book (CLOB) — the same matching engine architecture used by stock and futures exchanges. Buyers and sellers place limit and market orders, and the exchange matches them. Kalshi allocates roughly $35,000 per day (approximately $12.7 million annualized) in market-making incentives to maintain liquidity across its contract offerings.

Decentralized platforms like Polymarket use a hybrid model. Order matching happens off-chain for speed, but settlement occurs on-chain via the Polygon blockchain. Positions are settled in USDC, making Polymarket accessible to international users without U.S. banking relationships. Polymarket’s system relies on cryptographic signatures (EIP-712) for order authentication, a fundamentally different technical approach from traditional exchange infrastructure.

Settlement occurs when the event resolves. On Kalshi, winning contracts pay $1.00 in USD, deposited directly into the trader’s account via traditional banking. On Polymarket, winners receive USDC to their connected crypto wallet. The losing side of the trade receives nothing.

Here is a practical example. Suppose you believe there is a higher-than-market probability that the Fed will cut rates. The “Yes” contract is trading at $0.40, implying a 40% probability. You buy 100 contracts at $0.40, investing $40 total. If the Fed does cut rates, your contracts settle at $1.00 each — you receive $100, netting $60 in profit. If the Fed holds rates steady, your contracts expire worthless and you lose the $40.

This all-or-nothing payoff profile is what makes prediction markets accessible. There is no need to manage stop-losses or margin calls. Your maximum loss is always limited to what you paid for the contracts.

What can you trade on prediction markets?

The range of tradeable events has expanded dramatically, moving prediction markets well beyond their political betting origins. As of early 2026, major platforms offer contracts across several broad categories.

Financial and economic events represent the fastest-growing category and the one most familiar to forex and macro traders. Contracts cover Federal Reserve interest rate decisions, Consumer Price Index (CPI) releases, GDP growth numbers, employment data, and inflation forecasts. These events already drive currency markets — prediction markets offer a way to trade the outcome directly rather than positioning through derivatives.

Politics and elections remain the original core of prediction markets. The 2024 U.S. presidential election was the catalyst that pushed Polymarket into mainstream awareness, with billions in trading volume on election night alone. Platforms now cover elections globally, legislative outcomes, and policy decisions.

Sports have become a major growth driver. Kalshi reported over $1 billion in Super Bowl LX trading volume in February 2026, a 2,700% year-over-year increase. DraftKings and FanDuel have both launched prediction market products, leveraging their existing sports audience. FanDuel partnered with CME Group to list exchange-traded sports contracts, while DraftKings operates its own CFTC-licensed exchange through its acquisition of Railbird.

Crypto and technology events include price bracket contracts (Will Bitcoin exceed $X by a specific date?), protocol upgrade outcomes, regulatory decisions affecting digital assets, and technology milestones like product launches or AI benchmarks.

Cultural and entertainment events round out the offering, covering awards ceremonies, media releases, and viral moments. While these categories typically attract lower volume, they broaden the platform’s appeal to audiences who might not engage with financial markets directly.

This category expansion matters because it transforms prediction markets from a single-event novelty into a continuous trading product. Unlike elections, which happen infrequently, economic data releases, sports seasons, and crypto market events create a constant stream of tradeable opportunities.

Major prediction market platforms

The prediction market landscape has consolidated around two dominant platforms — Kalshi and Polymarket — while a growing roster of brokerages and fintech firms distribute their products or build competing infrastructure.

Kalshi operates as a CFTC-regulated designated contract market (DCM), making it the primary venue for legally compliant prediction market trading in the United States. From roughly 3.3% market share in early 2024, Kalshi surged to approximately 66% of total prediction market volume by September 2025. This growth was driven largely by its regulatory license, which enabled distribution partnerships with Robinhood, Coinbase, and WeBull. Kalshi processes over $100 billion in annualized trading volume and $8.1 billion in monthly notional as of February 2026. Its API supports REST, WebSocket, and FIX 4.4 protocols — the same connectivity standards used by major stock and futures exchanges.

Polymarket remains the leading decentralized prediction market, settling trades in USDC on the Polygon blockchain. It captured early market leadership during the 2024 election cycle and maintains strong positioning in political and crypto-native event categories. Polymarket’s recent acquisition of Dome, a Y Combinator-backed unified prediction market API, signals a strategic shift toward becoming infrastructure for other platforms rather than solely a consumer-facing product.

The following table summarizes the major platforms and brokerages that have launched prediction market products:

The competitive dynamics are shifting. Both Robinhood and Coinbase are building their own CFTC-licensed exchange infrastructure, expected to be operational in 2026. If successful, this would allow them to disintermediate Kalshi and capture the full revenue stack — from order matching to clearing and settlement. This vertical integration trend mirrors what happened in the crypto exchange space, where platforms that initially relied on third-party liquidity eventually built their own matching engines.

For traders, this competition is broadly positive. More platforms mean tighter spreads, broader event coverage, and integrated trading experiences where prediction market contracts sit alongside stocks, crypto, and forex in a single account.

How forex brokers are entering prediction markets

Prediction markets represent the most significant new product opportunity for forex brokerages since cryptocurrency CFDs. The trading mechanics translate naturally: binary outcome contracts priced between $0 and $1 are conceptually similar to the instruments FX traders already understand. The infrastructure is maturing fast enough that brokers can integrate prediction markets without building from scratch.

Three distinct integration pathways have emerged, each suited to different business profiles.

White-label turnkey solutions offer the fastest route to market. Providers like Leverate, which launched its prediction markets platform in February 2026, deliver fully branded interfaces that integrate alongside existing trading products. Leverate reports that its platform is compatible with MetaTrader 4 and MetaTrader 5 — the dominant retail forex trading terminals — and covers sports, politics, crypto, and financial event categories. Other providers include Tradesmarter, which targets crypto-native and mobile-first audiences with a Polymarket-style interface, and Devexperts, which released a DXtrade events module designed specifically for CFD brokers. Deployment timelines for white-label solutions range from two to eight weeks.

API-first integration suits brokerages with in-house development teams seeking greater product control. DriveWealth announced a partnership with Kalshi in February 2026 to embed event contracts via API, enabling fintech partners to offer prediction markets alongside equities and ETFs. Kalshi’s API uses REST, WebSocket, and FIX 4.4 protocols — the same connectivity standards already in use at most professional trading firms. For brokerages running MetaTrader environments, Kalshi’s API represents the lower-friction path compared to blockchain-native integration. Development timelines typically run three to six months.

Custom builds on open-source infrastructure represent the highest-investment pathway. The Gnosis Conditional Tokens Framework (CTF) — the same smart contract infrastructure that underpins Polymarket — is publicly available for firms that want full control over market creation, settlement logic, and fee structures. This approach requires significant engineering resources and is justified only when prediction markets are intended as a core product line rather than an add-on.

For traders, the broker integration trend matters because it means prediction market contracts will increasingly appear inside platforms you may already use. Rather than opening a separate account on Kalshi or Polymarket, you may soon trade event contracts directly within your existing forex or multi-asset brokerage account.

Regulatory landscape for prediction markets

The regulatory environment is the single biggest variable shaping how prediction markets develop. As of early 2026, the landscape is favorable at the federal level in the United States but remains contested at the state level and unresolved internationally.

In the United States, the CFTC has taken a strongly supportive stance. On January 29, 2026, Chairman Michael Selig announced a four-part regulatory agenda that represents the most significant pro-prediction-market policy signal from a U.S. regulator to date. The key actions included withdrawing a 2024 proposed rule that would have prohibited political and sports event contracts, announcing new rulemaking to establish clear standards, and committing to harmonize jurisdiction with the SEC.

On February 17, 2026, the CFTC filed an amicus brief in the Ninth Circuit supporting Crypto.com against the state of Nevada, marking the first time under Chairman Selig that the agency took an active legal position defending prediction markets against state-level gambling regulation. This represents a 180-degree reversal from the prior administration’s enforcement posture.

However, several states — including Massachusetts, Nevada, and Utah — have moved to restrict prediction markets through lawsuits and cease-and-desist orders, asserting that these platforms constitute unlicensed gambling. This federal-state conflict may ultimately require Supreme Court resolution.

In the European Union, the situation is more restrictive. ESMA’s 2018 ban on binary options for retail investors remains in effect, and event contracts are structurally similar to binary options. Kalshi has acknowledged that some of its contracts “are structured as binary options.” Until EU regulators issue explicit guidance distinguishing prediction markets from prohibited binary options, platforms serving EU retail clients face significant classification risk. MiCA implementation in 2026 adds additional complexity for crypto-settled prediction markets.

In the United Kingdom, the regulatory framework is split. Matchbook has launched prediction markets under a Gambling Commission license, which is viable for sports and entertainment events. Financial prediction markets — covering interest rates or economic data — would require FCA authorization, which remains untested. The binary options ban applies here as well.

The UAE and MENA region presents the lowest regulatory friction globally. No specific prohibition exists on event contracts, the DFSA and SCA oversight frameworks accommodate innovative financial products, and there is no personal income tax on trading gains. The region’s time zone bridges Asian and European sessions, and Interactive Brokers already serves UAE-based prediction market traders.

In Brazil, the securities regulator (CVM) approved the B3 exchange to launch prediction market derivatives in Q1 2026, initially covering USD/BRL, Ibovespa, and Bitcoin price outcomes. Access is currently restricted to professional investors holding R$10 million or more in financial assets. Retail access is expected to require additional regulatory clarity in the 2026–2027 timeframe.

Risks and challenges

Prediction markets offer a compelling trading opportunity, but several meaningful risks deserve attention.

Regulatory fragmentation is the most significant concern. The unresolved federal-state conflict in the United States creates compliance uncertainty, and at least 12 states have taken action to restrict prediction market platforms. Outside the U.S., the lack of clear classification — is this a financial instrument, a derivative, or gambling? — exposes platforms and users to shifting regulatory treatment.

Market integrity and insider trading present unique challenges. Prediction markets are inherently vulnerable to information asymmetry. Someone with advance knowledge of a regulatory decision, corporate announcement, or sports outcome could trade on that information before it becomes public. The CFTC has acknowledged that it is still developing frameworks for insider trading enforcement in event contract contexts. Several high-profile incidents have already drawn scrutiny to this issue.

Liquidity concentration varies dramatically across event categories. Popular events like presidential elections and Super Bowl outcomes attract deep order books and tight spreads. Niche markets — a local election, a specific technology milestone — may suffer from thin liquidity, wide bid-ask spreads, and difficulty exiting positions at fair prices.

Classification risk affects both platforms and traders. In jurisdictions where prediction markets are classified as gambling rather than financial instruments, winnings may be taxed differently, consumer protections may not apply, and platforms may face licensing requirements designed for casinos rather than exchanges.

Technology and settlement risk differs by platform architecture. Blockchain-settled platforms like Polymarket carry smart contract risk (bugs in code) and potential network congestion during high-volume events. Centralized platforms like Kalshi carry traditional counterparty risk and have experienced downtime during peak demand periods. White-label solutions introduce vendor dependency — if the provider experiences issues, all downstream brokers are affected.

The future of prediction markets

The trajectory of prediction markets depends largely on how the regulatory landscape resolves. Three scenarios frame the range of outcomes.

In the bull case (estimated roughly 45% probability), the CFTC finalizes supportive rulemaking by late 2026, state-level challenges are dismissed or preempted, and the EU carves out an exemption for event contracts from its binary options ban. Under this scenario, prediction markets become a standard feature of multi-asset brokerages within 12 months, similar to how cryptocurrency trading went from novelty to expected offering.

In the base case (roughly 40% probability), regulatory clarity emerges gradually over 18 to 36 months. The CFTC finalizes rules in late 2026, but state litigation continues in parallel. The EU maintains its binary options ban for retail clients. Brokers operate prediction markets with geographic restrictions, capturing first-mover advantage in permissive jurisdictions while waiting for broader regulatory green lights.

In the bear case (roughly 15% probability), the Supreme Court rules that states retain authority to regulate prediction markets as gambling, and the EU classifies event contracts as prohibited binary options. The market fragments into jurisdiction-by-jurisdiction licensing, limiting growth to offshore and crypto-native platforms.

Regardless of which scenario plays out, several structural trends are clear. The convergence of traditional brokerage and prediction market infrastructure is already underway — Robinhood, Interactive Brokers, and Plus500 have all launched products, and DriveWealth is enabling API-based distribution for any fintech partner. Monthly active users have grown from roughly 4,000 in early 2024 to over 600,000 by early 2026. The sector posted a record $702 million in single-day trading volume and regularly sustains $6 billion in weekly volume.

The platforms and brokerages that establish prediction market products now are positioning for a future where event contracts sit alongside stocks, forex, crypto, and commodities as a standard asset class. For traders, this means a growing set of venues and tools for expressing views on real-world outcomes — with the trading infrastructure to support it.
