Editor's Note: Prediction markets are transitioning from niche crypto applications to a more mainstream intersection of finance and information.

The 2024 U.S. election brought Polymarket and Kalshi into the public eye, but what truly shifted the industry narrative was the fact that post-election, trading volume did not rapidly diminish. Markets in sports, technology, and economics captured the traffic, proving that the long-term demand for prediction markets is not solely driven by political events.

This article outlines the core landscape of the 2026 prediction markets: on one side, a duopoly formed by Polymarket and Kalshi, with the former expanding its influence through on-chain transactions, USDC settlement, and media distribution, and the latter leveraging CFTC compliance accreditation and channels like Robinhood to enter the mainstream financial scene; on the other side, a new set of platforms is exploring opportunities in short-term trading, sports prediction, media integration, on-chain native metrics, and infrastructure layers.

Of particular note is that the competition in the prediction market is no longer just about trading volume but a comprehensive competition of liquidity, distribution capability, and regulatory pathways. Simultaneously, issues such as volume inflation, trade volume statistic disputes, token airdrop expectations, and state-level regulatory pressure indicate that this race is still in a highly uncertain phase.

The prediction market is no longer just a DeFi experiment. It is becoming a new asset class where financial transactions, media content, and algorithmic strategies converge. In the future, the platforms with a real chance to break out may not be the generalized replicas but those with clear vertical domain scenarios and distribution advantages.

The following is the original text:

Two platforms that were relatively unknown in 2022 settled a nominal trading volume last year that exceeded New Zealand's GDP.

In 2025, the combined trading volume of Kalshi and Polymarket reached $44 billion. In May 2026, Kalshi was valued at $22 billion and completed a $1 billion funding round. The parent company of the New York Stock Exchange, ICE, committed to invest $2 billion in Polymarket at a $9 billion valuation. The AI Agent has executed over 30% of on-chain transactions. Meanwhile, a new wave of teams is building vertically specialized platforms on Base, Solana, Hyperliquid, and Arweave — all betting on one judgment: these two giants cannot monopolize every category.

This may be the most comprehensive overview of the prediction market builder ecosystem to date.

Rewriting the Narrative in Numbers

2024 is the validation moment for prediction markets. The US presidential election alone brought $3.3 billion in trading volume to Polymarket. During the campaign, nearly every major financial newsroom began reporting on prediction market odds. Bloomberg, Politico, and FiveThirtyEight all referenced these data points in their analyses.

But what happened after November 5 took many by surprise: the trading volume didn't drop back to pre-election levels. The sports market caught this influx.

By the end of 2025, the sports market held 85% of Kalshi's trading volume and 39% of Polymarket's. Tech and science markets saw a 1,637% year-over-year growth, with economic markets up by 905%. The political markets—once thought to be the core driver of prediction markets—only grew by 43%.

The prediction market found its long-term engine, and it wasn't elections.

Duopoly Dynamics

Polymarket operates on Polygon, settles in USDC, and intentionally does not charge fees on most markets, prioritizing building a trading volume advantage. In October 2025, ICE made a $20 billion strategic investment at a valuation of around $90 billion. In June 2025, X announced Polymarket as its official prediction market partner. In February 2026, Substack natively integrated Polymarket's real-time odds data; within a few weeks, one-fifth of the top 250 revenue-generating Substacks started using this data. The platform's CMO also confirmed that the POLY token and airdrop are on the way. With full functionality deployed, its projected annualized fee revenue will exceed $2 billion.

Kalshi secured CFTC designation as a contract market, becoming the first event derivatives platform to achieve such status and turning it into a distribution barrier. It was this regulatory qualification that allowed Kalshi to onboard Robinhood. In just 2025, Robinhood facilitated over 4 billion event contract trades. In January 2025, Kalshi launched markets related to the Super Bowl. In less than 12 months, the sports market's share of its trading volume skyrocketed from around 10% to over 85%. In May 2026, Kalshi closed a $1 billion funding round with a valuation of $22 billion, led by Coatue with participation from Sequoia, a16z, Paradigm, Morgan Stanley, and ARK. At the time of the funding round, Kalshi had around 2 million monthly active users, an annualized trading volume of approximately $178 billion, and annualized revenue of about $15 billion.

By 2025, these two companies collectively controlled about 97.5% of the entire prediction market industry's trading volume.

Ecosystem Map

Challengers

Outside of the duopoly, there are already over a dozen teams building new prediction market platforms. Each of them is targeting a specific niche.

@trylimitless is deployed on Base, focusing on short-term markets including 15-minute, hourly, and daily markets, catering to cryptocurrency and stock traders looking for quick settlement. The project raised $10 million from institutions such as 1confirmation, Coinbase Ventures, F-Prime, DCG, and Arrington. In the first quarter of 2026, its monthly trading volume reached $1.1 billion. Following the launch of the $LMTS token, its fully diluted valuation briefly reached $800 million.

@MyriadMarkets operates on the Abstract chain and integrates Linea, Celo, and BNB. It is betting on "media-native" prediction markets. Its first distribution partnership took place in December 2025 when the platform embedded prediction features into Trust Wallet. It now has over 430,000 users with over 1.7 million predictions made. The project was founded by the team behind Decrypt and Rug Radio.

KASH integrates with X through @kash_bot, allowing users to create and trade prediction markets within referenced posts. In February 2026, KASH raised $2 million from institutions like Big Brain Holdings, Spartan, Coinbase Ventures, Animoca, and Sui Foundation. Its core thesis is: whoever can enter the scene where users already are in the shortest path will win the prediction market.

@DriftProtocol is built on top of the $500 million Solana liquidity pool of Drift Protocol. It supports over 30 staked assets, allows cross-margin positions, and offers FUEL rewards.

@HedgehogMarket targets on-chain native metrics such as Base fees, funding rates, validator performance, and also provides general binary options on Solana and Eclipse. The platform supports permissionless market creation, with peak TVL reaching around $20 million.

The HIP-4 by @HyperliquidX went live on May 2, 2026, co-designed by Kalshi's Crypto Lead John Wang. The mechanism is fully collateralized in USDH, follows a CLOB order book model, and does not charge any opening fees. The first market was deployed by the Hyperliquid team, centered around BTC outcomes, achieving a trading volume of $6 million on the launch day. Currently, @Outcomexyz is the primary frontend for HIP-4, contributing a trading volume more than 10 times greater than any other interface.

@azuroprotocol acts more like infrastructure than a frontend product for the general user. It provides a sports prediction market layer to other teams, utilizing the Liquidity Tree liquidity pool design. The project has raised $11 million in funding from institutions such as Delphi Digital, Gnosis, and Arrington Capital.

@Overtime_io operates on Optimism, Arbitrum, and Base. All protocol revenues flow into $OVER token buybacks.

@RobinhoodApp is backed by Kalshi's backend and facilitated over 2 billion event contract trades in just the third quarter of 2025.

The infrastructure layer is also heating up. In August 2025, @theclearingco completed a $15 million seed round with investors including Union Square Ventures, Haun Ventures, Coinbase Ventures, and Variant. The company was founded by former executives of Polymarket and Kalshi. Capital is starting to flow to the clearinghouse layer, often signaling the maturation of an asset class.

Key Drivers of 2026

Regulated platforms are seeking on-chain tracks. Kalshi is tokenizing markets and deploying on Solana, Polymarket advances U.S. CFTC compliance through the acquisition of QCEX, and Hyperliquid's HIP-4, co-designed by Kalshi — all these actions point in one direction: a global liquidity layer at the base, overlaid with regulatory shells from different regions.

AI Agents have become an integral part of prediction market activity. According to analytics platform LayerHub, over 30% of wallets on Polymarket are running an AI Agent. Olas' Polystrat Agent executed over 4,200 trades in its first month, with a maximum single position yield of 376%. Elastics also secured a $2 million funding, attempting to build a natural language trading interface.

Whether by design from the platform team or not, the prediction market is turning into an algorithmic trading venue.

Media platforms are treating prediction odds as a highly sticky content. Official partnerships' agreements of X, Substack's native integration, and Google Finance displaying real-time odds all serve essentially the same purpose: transforming financial questions into media events open for communal discussion, thus driving organic user acquisition.

Sports represent the most sustainable vertical path. The 2024 U.S. election brought in the first wave of users, while sports retained them. Any new platform that raises funding in 2026 without a sports strategy is either building deep infra or making a highly concentrated bet on a niche.

The Real Challenge

There are three risks worth pointing out directly.

First, the trading volume metric itself is contentious. An analysis released by Paradigm in December 2025 highlighted that Polymarket's NegRisk architecture leads to most third-party data tracking tools double-counting. CertiK estimated that wash trading accounted for almost 60% peak of Polymarket's trading volume in 2024. Hence, the $440 billion figure is more suitable as a directional reference rather than a rigorously audited accurate data.

Second, state-level legal frictions are a tangible reality. As of January 2026, over 19 related federal litigations have been filed. In March 2026, Ohio ruled Kalshi's sports product as gambling. Wisconsin and Arizona's Attorneys General have also taken action against the two major platforms. While there is a federal tailwind from the CFTC, strong state-level resistance coexists, and this tension is not likely to dissipate soon.

Third, token speculation is driving platform activity. In 2025 and early 2026, a significant portion of the trading volume was related to the market's anticipation of the POLY airdrop. Any platform that only publishes impressive trading volume figures without explaining this context is misleading readers.

Conclusion

In 2024, the prediction market completed the transition from a "fun DeFi experiment" to a financial asset class. By 2025, it started building institutional-grade pipelines: the exchange parent company's strategic investments, CFTC settlements, Robinhood integration, and seed round funding at the clearinghouse level.

By 2026, the real question this space will have to answer is: Apart from Kalshi and Polymarket, who else has a shot?

The current answer: Teams deeply rooted in a vertical, with a clear distribution advantage, and able to find a regulatory safe harbor or on-chain liquidity depth.

The window for generalized clones has closed. Other paths, however, remain open.

If you're building in this space and seeking the right growth architecture for your vertical, let's chat.
