Editor's Note: Prediction markets are evolving from a niche crypto application to a more mainstream financial and information market.

The 2024 US election brought Polymarket and Kalshi into the public eye, but what truly changed the industry narrative was that trading volume did not rapidly disappear after the election. Markets in sports, technology, and economics absorbed 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 prediction markets in 2026: on one side, a duopoly formed by Polymarket and Kalshi, with the former expanding its influence through on-chain trading, USDC settlement, and media distribution, and the latter entering mainstream financial scenarios through CFTC compliance qualifications and channels like Robinhood. On the other side, a group of new platforms are seeking opportunities in short-cycle trading, sports prediction, media embedding, on-chain native metrics, and the infrastructure layer.

What's more noteworthy is that the competition in prediction markets is no longer just about trading volume; it's a comprehensive contest involving liquidity, distribution capabilities, and regulatory pathways. Meanwhile, issues like wash trading, disputes over trading volume statistics, expectations for token airdrops, and state-level regulatory pressure indicate that this sector is still in a highly uncertain stage.

Prediction markets are no longer just DeFi experiments. They are becoming a new asset class where financial trading, media content, and algorithmic strategies intersect. The platforms that truly have a chance to break through in the future may not be generalized replicas, but rather those with clear vertical scenarios and distribution advantages.

The following is the original text:

Two platforms that were barely known in 2022 settled a notional 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 raised $1 billion in funding at a valuation of $22 billion. The Intercontinental Exchange (ICE), parent company of the New York Stock Exchange, pledged a $2 billion investment in Polymarket at a $9 billion valuation. AI Agents are already executing over 30% of on-chain trades. Meanwhile, a group of new teams are building vertical-specific platforms on Base, Solana, Hyperliquid, and Arweave—they are all betting on one judgment: these two giants cannot monopolize all categories.

This is likely the most comprehensive overview of the prediction market builder ecosystem available today.

Numbers That Rewrote the Narrative

2024 was the validation moment for prediction markets. The single market of the US Presidential election alone brought $3.3 billion in trading volume to Polymarket. During the campaign, almost all major financial news desks began reporting prediction market odds. Bloomberg, Politico, and FiveThirtyEight cited this data in their analyses.

But what happened after November 5th surprised many: trading volume did not drop back to its previous baseline. Sports markets absorbed that traffic.

By the end of 2025, sports markets accounted for 85% of Kalshi's trading volume and 39% of Polymarket's. Tech & Science markets grew 1,637% year-over-year, and Economic markets grew 905%. Political markets—the vertical once assumed to be the core driver of prediction markets—grew by only 43%.

Prediction markets found their long-term engine, and it wasn't elections.

The Duopoly Landscape

Polymarket runs on Polygon, settles in USDC, and intentionally charges no fees on most markets to prioritize building trading volume. In October 2025, ICE invested $2 billion in a strategic investment at a post-money valuation of approximately $9 billion. In June 2025, X announced Polymarket as its official prediction market partner. In February 2026, Substack natively integrated Polymarket's live odds data; within weeks, one-fifth of the top 250 revenue-generating publications on Substack began using this data. The platform's CMO also confirmed that the POLY token and an airdrop are forthcoming. Upon full functionality launch, its projected annualized fee revenue is expected to exceed $200 million.

Kalshi, on the other hand, obtained a Designated Contract Market designation from the CFTC, becoming the first event contract platform with such credentials, and turned this into a distribution moat. It was this compliant status that enabled Kalshi to enter Robinhood. In 2025 alone, Robinhood facilitated over 4 billion event contract trades. In January 2025, Kalshi launched markets related to the Super Bowl. In less than 12 months, sports markets skyrocketed from roughly 10% to over 85% of its trading volume. In May 2026, Kalshi raised $1 billion at a $22 billion valuation, led by Coatue with participation from Sequoia, a16z, Paradigm, Morgan Stanley, and ARK. At the time of funding, Kalshi had approximately 2 million monthly active users, annualized trading volume of about $178 billion, and annualized revenue of about $1.5 billion.

In 2025, these two companies collectively controlled about 97.5% of the total trading volume in the prediction market industry.

Ecosystem Map

The Challengers

Beyond the duopoly, over a dozen teams are building new prediction market platforms. Each targets a specific gap.

@trylimitless is deployed on Base, focusing on short-cycle markets including 15-minute, hourly, and daily markets, targeting cryptocurrency and stock traders seeking fast settlement. The project raised $10 million from 1confirmation, Coinbase Ventures, F-Prime, DCG, and Arrington, among others. In Q1 2026, its monthly trading volume reached $1.1 billion. The fully diluted valuation of the $LMTS token once reached $800 million after launch.

@MyriadMarkets runs on the Abstract chain and integrates with Linea, Celo, and BNB. It bets on "media-native" prediction markets. Its first distribution partnership occurred in December 2025, embedding prediction features into Trust Wallet. It currently has over 430,000 users who have completed more than 1.7 million predictions. The project was founded by the team behind Decrypt and Rug Radio.

KASH embeds into X via @kash_bot, allowing users to create and trade prediction markets within quote posts. In February 2026, KASH raised $2 million from Big Brain Holdings, Spartan, Coinbase Ventures, Animoca, and the Sui Foundation, among others. Its core belief: whoever can enter the scenarios where users already spend their time via the shortest path will win prediction markets.

@DriftProtocol is built atop Drift Protocol's $500 million Solana liquidity pool. It supports over 30 collateral assets, allows cross-collateral positions, and offers FUEL rewards.

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

@HyperliquidX's HIP-4 went live on May 2, 2026, co-designed by John Wang, Head of Crypto at Kalshi. This mechanism uses USDH exclusively as collateral, employs a CLOB order book model, and charges no opening fees. The first market, deployed officially by Hyperliquid, revolves around BTC outcomes, achieving $6 million in trading volume on its first day. Currently, @Outcomexyz is the primary frontend for HIP-4, contributing 10x the trading volume of any other interface.

@azuroprotocol is more like infrastructure than a frontend product for general users. It provides a sports prediction market layer for other teams, using a Liquidity Tree pool design. The project has raised $11 million from Delphi Digital, Gnosis, and Arrington Capital, among others.

@Overtime_io runs on Optimism, Arbitrum, and Base. All protocol revenue flows to $OVER token buybacks.

@RobinhoodApp is powered by Kalshi's backend, facilitating over 2 billion event contract trades in Q3 2025 alone.

The infrastructure layer is also heating up. In August 2025, @theclearingco raised a $15 million seed round from investors including Union Square Ventures, Haun Ventures, Coinbase Ventures, and Variant. The company was founded by former executives from Polymarket and Kalshi. Capital flowing to the clearinghouse layer usually signals that an asset class is maturing.

Core Drivers in 2026

Regulated platforms are exploring on-chain tracks. Kalshi tokenizing markets and deploying to Solana, Polymarket advancing US CFTC compliance through the acquisition of QCEX, and Hyperliquid's HIP-4 being co-designed by Kalshi—all these moves point in the same direction: a global liquidity layer at the base, overlaid with regulatory shells for different regions.

AI Agents have become a non-negligible part of prediction market activity. According to analytics platform LayerHub, over 30% of wallets on Polymarket are running AI Agents. Olas's Polystrat Agent executed over 4,200 trades in its first month, with single-position returns as high as 376%. Elastics also raised $2 million, aiming to build a natural language trading interface.

Whether platform teams initially designed for it or not, prediction markets are becoming algorithmic trading venues.

Media platforms are treating prediction odds as high-engagement content. X's official partnership deal, Substack's native integration, and Google Finance displaying live odds essentially serve the same purpose: turning financial questions into media events that can be discussed collectively, thereby driving organic user acquisition.

Sports is the most sustainable vertical. The 2024 US election brought the first wave of users; sports kept them. Any new platform raising funds in 2026 without a sports strategy is either building deep infrastructure or making a highly concentrated bet on a specific niche.

The Real Challenges

Three risks are worth pointing out directly.

First, trading volume metrics themselves are controversial. An analysis published by Paradigm in December 2025 noted that Polymarket's NegRisk architecture causes most third-party data tracking tools to double-count. CertiK estimated that wash trading accounted for peaks near 60% of some Polymarket trading volume in 2024. Therefore, the $44 billion figure is better used as a directional reference rather than strictly audited, accurate data.

Second, state-level legal friction is real. As of January 2026, there were over 19 related federal lawsuits. In March 2026, Ohio ruled that Kalshi's sports products constituted gambling. Attorneys General in Wisconsin and Arizona have also taken action against both major platforms. Federal tailwinds from the CFTC coexist with strong headwinds at the state level, and this tension won't disappear soon.

Third, token speculation is driving platform activity. A significant portion of trading volume in 2025 and early 2026 was related to market expectations for the POLY airdrop. Any platform touting impressive trading volume numbers without disclosing this context is misleading readers.

Conclusion

In 2024, prediction markets completed the leap from "interesting DeFi experiment" to a financial asset class. By 2025, they began building institutional-grade pipelines: strategic investments from exchange parent companies, CFTC-related settlements, Robinhood integration, and seed funding for clearinghouse layers.

In 2026, the real question for this sector has become: Who else has a chance to win besides Kalshi and Polymarket?

The current answer: Teams that go deep in verticals, possess clear distribution advantages, and can find paths for regulatory protection or on-chain liquidity density.

The opportunity for generalized replicas is over. Other paths, however, remain open.

If you are also building in this space and want to find the right growth architecture for your vertical, let's talk.
