Why is Prediction Market So Popular? Is It Gambling?

As of early January 2026, prediction markets have evolved from niche experiments among crypto enthusiasts and academic economists into essential tools within the global information ecosystem. These platforms, where participants wager real capital on future outcomes to generate crowd-sourced probabilities, are now routinely cited by hedge funds, media outlets, political strategists, journalists, and policymakers.

In an era marked by geopolitical tensions, AI-driven misinformation, economic volatility, and political polarization, prediction markets provide unbiased, incentive-aligned forecasts that often outperform traditional polls, expert opinions, and financial indicators.

What sets them apart is the “skin in the game” principle, ensuring participants back their beliefs with tangible stakes. This shift is transforming prediction markets into a serious alternative for data-driven decision-making, with momentum building toward mainstream adoption.

The Scale and Inflow of Capital in Prediction Markets

The prediction market sector has demonstrated explosive growth, underscoring its potential as a major financial and informational force. In the final months of 2025, combined trading volumes across leading platforms like Polymarket and Kalshi surged to approximately $40 billion, marking a dramatic expansion from earlier years.

Kalshi alone achieved $23.8 billion in nominal volume—a staggering 1,108% year-over-year increase from 2024—while Polymarket hit peaks such as $3.74 billion in November 2025, with monthly volumes occasionally exceeding $4 billion. By year-end, open interest across the industry reached around $849 million, and weekly notional volumes climbed to $4.5 billion among key players.

This influx of capital reflects broadening appeal, extending beyond crypto-native users into mainstream finance, politics, and beyond. Industry projections forecast annual volumes potentially hitting $1 trillion by the end of the decade, fueled by regulatory advancements, blockchain scalability, and AI integrations.

For 2026 specifically, experts predict prediction markets will become the fastest-growing crypto application, with open interest rising to $0.5 billion and volumes accounting for 3% of centralized exchange activity. All indicators suggest sustained capital inflows, positioning the sector for significant expansion throughout 2026 and into the future.

What is Prediction Market?

Prediction markets aren’t a 21st-century invention; their conceptual foundations trace back centuries. In the 19th century, informal betting on elections and horse races aggregated crowd wisdom, but formalized versions emerged in academia during the 20th century.

The Iowa Electronic Markets (IEM), established in 1988 by the University of Iowa, pioneered small-scale electronic trading on political outcomes. Over decades, IEM consistently outperformed national polls in U.S. presidential elections, achieving accuracy rates up to 10% higher in vote-share predictions.

Early versions appeared in academic settings as tools for forecasting elections and economic indicators. Later, platforms like the Iowa Electronic Markets demonstrated that small, well-designed markets could outperform large-scale opinion polls.

Despite theoretical promise, early markets faced insurmountable hurdles: regulatory friction limited participation, centralized platforms created trust issues, settlement mechanisms were slow and opaque, and global access was nearly impossible.

The blockchain revolution in the 2010s shattered these constraints. Decentralized protocols enabled permissionless access, transparent on-chain records, and automated smart-contract settlements. By 2024, platforms like Polymarket had already notched $9 billion in volume, but 2025 marked the “Big Bang” expansion.

Weekly volumes exceeded $2 billion for the first time in October 2025, fueled by U.S. regulatory nods from the CFTC and integrations with mainstream apps like Robinhood. This infrastructure shift transformed prediction markets from theoretical curiosities into scalable, global systems.

Crypto changed all of that, removing intermediaries, enabling automated settlement, and allowing markets to exist without geographic or institutional constraints. What was once a theoretical tool became a scalable system.

At its core, a prediction market is a marketplace where people trade contracts based on the outcome of future events. It is a system for pricing uncertainty. Participants trade contracts tied to future events, each representing a specific outcome. These outcomes are binary or multi-outcome, clearly defined, and time-bound. Each contract represents a specific outcome—for example:

• Who will win an election (e.g., “Candidate A wins the 2026 election”)
• Whether a company’s stock will reach a certain price (e.g., “Bitcoin trades above $100,000 by December 31”)
• If an ETF will be approved (e.g., “The ETF is approved before Q3”)
• Whether inflation will exceed a target level (e.g., “Inflation exceeds 4% this quarter”)
• Sports and Culture: Bets on NFL outcomes and celebrity events
• Niche and Emerging: Short-term crypto price predictions, like on platforms such as Limitless on Base, which handled $760 million in volume and 50,000+ active traders

Each contract trades between $0 and $1. The price of a contract reflects the collective belief of the market about the probability of that event happening. If a contract trades at $0.70, the market is essentially saying there is a 70% chance the event will occur. The price is not symbolic. It is the market’s best estimate of probability at that moment in time.

• A price of $0.20 implies a 20% chance
• $0.65 implies a 65% chance
• $0.90 implies strong conviction

Trading Dynamics: Contracts trade in a $0–$1 range, where the price directly equates to the market’s implied probability. For instance, a contract at $0.72 signals a 72% likelihood of the “yes” outcome. At resolution, winners receive $1 per contract; losers get nothing.

When the event is resolved: Contracts tied to the correct outcome pay out (often $1), incorrect outcomes become worthless. Resolution Process: Outcomes are settled via oracles (e.g., Chainlink for on-chain data) or dispute mechanisms like token-holder voting (e.g., UMA for Polymarket). This ensures objectivity, though disputes can arise in ambiguous cases. There is no ambiguity. No interpretation. Reality decides.

In simple terms, prediction markets turn future uncertainty into tradable probabilities. Beyond trading, these markets serve broader purposes: hedging risks (e.g., companies betting on regulatory approvals), decision-making (DAOs using probabilities for governance), and even scientific forecasting (e.g., AI development milestones).

Real-world examples from 2025 illustrate their versatility:

• Politics: Markets on the 2024 U.S. election (resolved in 2025) saw Polymarket volumes exceed $2 billion, accurately forecasting Donald Trump’s victory with probabilities stabilizing at 65% weeks ahead—outpacing polls like FiveThirtyEight.
• Crypto and Finance: “Will Bitcoin surpass $150,000 by December 31, 2025?” contracts traded heavily, with volumes in the hundreds of millions, reflecting macro sentiment.
• Economics: Inflation forecasts, like “U.S. CPI above 3% in Q4 2025,” aggregated trader insights faster than Federal Reserve models, acting as leading indicators.
• Sports and Culture: Kalshi’s sports markets exploded, capturing 75% of its volume by year-end.
• Globally, volumes hit $18.8 billion in December alone.

Why Prediction Market is Popular?

Several forces drove the rise of prediction markets toward the end of 2025, culminating in their explosive growth. Prediction markets’ meteoric rise in 2025 stemmed from multiple converging factors, each backed by empirical evidence.

The Collapse of Trust in Traditional Forecasting / Erosion of Trust in Legacy Systems

Polls are biased. Experts are political. Institutions are slow. Traditional polls and experts faltered amid polarization and bias. In many domains—especially politics and macroeconomics—traditional forecasting tools have lost credibility. People no longer trust surveys that can be manipulated, framed, or selectively reported.

Prediction markets don’t ask for opinions. They demand commitment. When money is involved, signaling changes. Bluffing becomes expensive. Confidence must be backed by conviction. This alone makes prediction markets uniquely powerful. In contrast, prediction markets demand financial commitment, reducing noise.

A 2025 study analyzing $2.4 billion in political trades found markets outperforming chance 67–93% of the time, with Brier scores (a measure of forecast accuracy) near 0.09—superior to polls. Economics markets alone grew 905% to $112 million.

Information Efficiency / Efficient Information Aggregation at Scale / Information Aggregation at Scale

Prediction markets aggregate data from thousands of participants. This often makes them more accurate than polls, expert opinions, or forecasts from single institutions. Each participant brings partial information: A trader interprets macro data, a journalist understands political incentives, an industry insider notices subtle signals, a retail participant reacts to breaking news.

Prediction markets compress all of this into a single number: price. That price updates continuously, absorbing new information faster than committees, reports, or centralized models ever could.

In this sense, prediction markets are not just markets—they are distributed intelligence systems. Diverse participants—insiders, analysts, retail traders—contribute fragmented knowledge, distilled into dynamic prices. This “distributed intelligence” updates in real-time, often ahead of news cycles. For instance, Polymarket probabilities shifted on inflation data before official releases, serving as macro leading indicators.

Case Studies of Superiority: In the 2024 election cycle (resolved 2025), markets like Polymarket achieved 74% accuracy over polls in key races.

Decentralization and Crypto Infrastructure / Blockchain and Regulatory Tailwinds / Crypto-Native Design Enables Global Truth Discovery

Blockchain-based platforms have removed intermediaries, enabling: Global participation, Transparent settlement, Permissionless access. This aligns perfectly with the broader Web3 and DeFi movement. Decentralized prediction markets benefit from core blockchain properties: Permissionless access, Transparent mechanics, Automated settlement, Resistance to censorship.

This matters most for controversial or politically sensitive topics, where centralized platforms may face pressure or restrictions. On-chain markets don’t care about narratives. They care about outcomes. Decentralized features like censorship resistance enabled global access, while CFTC approvals for Kalshi boosted legitimacy. U.S. re-entry for Polymarket via acquisitions amplified volumes.

By Q4 2025, sports betting dominated, comprising 75% of Kalshi’s activity.

Demand for Alternative Signals

Traders, investors, and analysts increasingly use prediction markets as real-time sentiment indicators—especially in politics, macroeconomics, and crypto regulation.

Low Barrier to Entry

Many prediction markets allow small bets, making participation accessible while still offering meaningful insights.

A New Class of Market Participants / Diverse Ecosystem and Participants

Prediction markets attract a unique mix of users: Traders seeking asymmetric information, Analysts testing hypotheses in real time, Investors hedging regulatory or macro risk, Observers using markets purely as signal tools. Not everyone is there to “bet”. Many are there to listen. In fact, some of the most valuable users never place trades at all—they simply watch probability shifts as an alternative data feed.

From hedge funds using signals for arbitrage (e.g., Goldman Sachs integrations) to passive observers tracking mindshare (Polymarket hit 67% dominance). New entrants like OpinionLabs ($1.6B weekly volume) and MyriadMarkets expanded the pie. Platforms like PBX (air quality predictions) and Spaace (Solana-based) target long-tail topics.

What Can Be Consider Gambling?

Traditionally, gambling involves: Placing money on outcomes driven mostly by chance, Limited ability to influence or analyze the result, Negative expected value due to house edge.

Examples include: Casino games, Slot machines, Pure luck-based betting.

The key characteristics are randomness and lack of informational advantage.

Gambling is defined by three core traits: Outcomes dominated by randomness, No meaningful informational edge, Structural negative expected value (house edges 5–10%).

Casinos are designed so that, over time, the player loses. Skill does not change the math.

Is Prediction Market Gambling?

The debate over whether prediction markets constitute gambling is persistent, but it is often framed incorrectly. Many critics treat “gambling” and “investment” as a binary distinction, when in reality prediction markets do not fit neatly into either category. To evaluate them properly, we must look beyond surface similarities and examine their economic structure, incentives, and information dynamics.

Why Prediction Markets Are Often Labeled as Gambling

At a glance, prediction markets resemble gambling for several reasons. Participants risk real money on uncertain future events, including elections, sports outcomes, or geopolitical developments. Some traders act emotionally, speculate without research, or chase momentum—behavior commonly associated with betting.

From a behavioral perspective, these similarities are undeniable. However, behavioral resemblance alone is insufficient to classify an activity as gambling. The underlying mechanics matter far more than how poorly some participants choose to engage with the system.

The Core Differences Between Gambling and Prediction Markets

Traditional gambling is defined by three structural traits: randomness, the inability to gain a persistent informational advantage, and a built-in house edge. Prediction markets systematically break all three.

• First, outcomes are not purely random.
  Casino games rely on chance. Prediction markets rely on real-world dynamics—policy decisions, incentives, institutional behavior, and human psychology. Prices move in response to information, not dice rolls.
• Second, informational edges are real and actionable.
  In gambling, knowing more does not meaningfully change expected value. In prediction markets, research, faster access to information, and superior analysis directly improve outcomes. Traders are not guessing numbers; they are interpreting data, incentives, and probability distributions.
• Third, many platforms lack a house edge.
  Casinos are mathematically designed to extract value from participants. Many decentralized prediction markets operate with zero or minimal fees and without a centralized counterparty. Expected value depends on skill relative to the market, not on rules engineered to guarantee participant losses.

An Economic Perspective: Informational Derivatives

From an economic standpoint, prediction markets function more like financial derivatives than gambling instruments. They facilitate price discovery and probability aggregation by incentivizing participants to reveal private information through market action.

Economists increasingly classify them as informational derivatives—tools that reward better information, better analysis, and faster reaction to new data. Empirical studies have shown that prediction markets consistently outperform random chance and, in some domains, rival expert forecasting.

This classification is critical to understanding why prediction markets are treated differently under U.S. law.

Why Prediction Markets Are Not Classified as Gambling in the United States

U.S. regulators focus on structure and function, not superficial resemblance. Gambling is legally associated with entertainment-based wagering on chance outcomes with a house advantage. Prediction markets, by contrast, provide measurable informational value, enable hedging, and function as probabilistic signaling mechanisms.

If prediction markets were broadly classified as gambling, many established financial instruments—such as options, futures, and credit default swaps—would face the same classification. The legal distinction exists because prediction markets contribute to information efficiency rather than exploiting randomness.

Risks Exist—But Risk Does Not Equal Gambling

Prediction markets are not inherently safe. Like any market, misuse leads to losses. Key issues observed in recent years include emotional trading, overconfidence in weak information, herd behavior during volatile events, wash trading that inflates volume, and disputes over outcome resolution due to oracle or governance weaknesses.

These problems mirror those found in traditional financial markets. Their presence indicates human error and structural immaturity, not gambling mechanics.

Conclusion

Prediction markets are not gambling by nature. They become gambling only when participants treat them as such.

Risk alone does not define gambling. Randomness, structural disadvantage, and the impossibility of gaining an edge do. Prediction markets fail to meet these criteria. They are markets—imperfect, evolving, and occasionally misused—but fundamentally driven by information, incentives, and analysis.

The difference between gambling and trading does not lie in the tool.

The Future of Prediction Markets (2026 and Beyond)

Looking ahead, prediction markets are likely to evolve in several directions: Integration with traditional finance as hedging tools, Use by institutions as alternative data sources, Regulatory frameworks distinguishing them from betting, Expansion into corporate governance and policy modeling.

Most importantly, they may become a standard lens for understanding uncertainty. In a world overloaded with opinions, narratives, and noise, prediction markets offer something rare: A price that reflects what people truly believe will happen—not what they want to say.

Looking to 2026, prediction markets are poised for institutional mainstreaming: Integration with Finance and AI: Hedging tools in DeFi; AI agents trading for optimized forecasts. Talus raised $10M for AI infrastructure. Regulatory Evolution: Frameworks distinguishing from betting; U.S. expansions via partners like DraftKings. Expansion Areas: Corporate governance (e.g., tokenized decisions), policy modeling, and global events. Volumes projected at 3% of CEX, OI at $0.5B. Global and Niche Growth: Platforms like PBX and Spaace target long-tail topics.

Ultimately, prediction markets may redefine how we quantify uncertainty, evolving from betting venues to foundational truth-discovery layers in media, finance, and beyond. With $44 billion in 2025 as a baseline, the trillion-dollar milestone feels increasingly attainable.
