The Current State of Prediction Markets

From Fringe to Financial Mainstream

In less than two years, prediction markets have undergone a transformation that few industries experience in a decade. What were once obscure platforms used primarily by political junkies and crypto enthusiasts have become a fixture of mainstream finance — complete with MLB partnerships, Robinhood integrations, and analyst projections of $1 trillion in annual volume by 2030, according to Bernstein estimates reported by CNBC in April 2026.

The catalyst was the 2024 U.S. presidential election. Polymarket's election markets became the go-to tracker for real-time political sentiment, generating more media attention than many traditional polls. But the real story was happening in courtrooms and regulatory offices, where a series of landmark decisions would determine whether prediction markets could legally operate — and expand — in the United States.

This article provides a comprehensive overview of where prediction markets stand today: the platforms competing for dominance, the regulatory framework taking shape, and the controversies that could define the industry's future.

The Regulatory Breakthrough: Kalshi vs. CFTC

The modern prediction market era in the U.S. effectively began with KalshiEx LLC v. CFTC, a legal battle that reshaped the industry's regulatory landscape.

Kalshi, a CFTC-regulated Designated Contract Market (DCM), had sought approval to list political event contracts — specifically, contracts on U.S. congressional election outcomes. The CFTC blocked the contracts under 17 C.F.R. § 40.11, which prohibits event contracts involving "excluded commodities" that relate to activities like gaming, terrorism, or war. The CFTC argued that election contracts constituted prohibited gaming activity.

Kalshi sued, and in September 2024, a federal district court vacated the CFTC's order. In October 2024, the D.C. Circuit Court of Appeals denied the CFTC's emergency motion to stay the ruling, effectively clearing Kalshi to list election contracts just weeks before the November 2024 presidential election. The Financial Times reported that election bets surged immediately after the court lifted the ban.

The final chapter came in May 2025, when the CFTC dropped its appeal entirely, cementing the precedent that political event contracts are permissible on regulated exchanges.

Key insight: The Kalshi ruling didn't just legalize political prediction markets — it signaled that the CFTC's interpretation of § 40.11 was overly broad, opening the door for event contracts across categories including sports, geopolitics, and economics.

Platform Landscape: Who's Competing and How

The prediction market ecosystem has rapidly diversified. Here's how the major players compare as of mid-2026:

Platform	Regulatory Status	Key Markets	Distribution Strategy	Notable Development
Kalshi	CFTC-regulated DCM	Politics, economics, sports, weather	Webull partnership, direct platform	$208M March Madness volume (Mar 2025)
Polymarket	Acquired CFTC-licensed QCEX (Jul 2025)	Politics, sports, crypto, geopolitics	MLB partnership, standalone platform	$112M QCEX acquisition
Railbird	CFTC-approved DCM (Jun 2025)	Sports-focused	Dedicated sports exchange	Fresh CFTC designation
Novig	Seeking CFTC approval	Peer-to-peer sports	P2P model	$18M Series A (Aug 2025)
Robinhood	Brokerage (partners with exchanges)	Politics, economics	Integrated into brokerage app	Launched prediction markets Mar 2025
FanDuel / CME Group	Partnership announced Aug 2025	Event contracts (TBD)	FanDuel user base + CME infrastructure	Combines sports betting audience with derivatives expertise

Kalshi: The Regulatory Pioneer

Kalshi's legal victory made it the first platform to offer regulated political event contracts in the U.S. The platform has aggressively expanded into sports, with $208 million in March Madness trading volume in March 2025 alone. Kalshi's partnership with Webull extends its reach to mainstream retail investors who may never have visited a dedicated prediction market platform.

However, Kalshi's sports expansion has drawn scrutiny. Business Insider reported that its sports predictions "came under fire" during March Madness, with critics questioning whether the contracts were functionally indistinguishable from sports gambling.

Polymarket: From Crypto Darling to Regulated Player

Polymarket's trajectory has been remarkable. Originally a crypto-native platform operating largely outside the U.S. regulatory perimeter, it became a cultural phenomenon during the 2024 election cycle. In July 2025, Polymarket acquired QCEX — a CFTC-licensed exchange and clearinghouse — for $112 million, signaling its intent to operate as a fully regulated U.S. entity.

The platform was designated as a DCM on July 9, 2025, according to CFTC industry filings. By March 2026, Polymarket had secured an exclusive prediction market partnership with Major League Baseball, a landmark deal that embedded event contracts directly into one of America's premier sports leagues.

The New Wave: Railbird, Novig, and FanDuel/CME

The success of Kalshi and Polymarket has attracted a wave of new entrants. Railbird Exchange received CFTC approval as a Designated Contract Market in June 2025, positioning itself as a sports-focused prediction exchange. Novig, which raised an $18 million Series A in August 2025, is pursuing a peer-to-peer model and claims to be the fastest-growing platform in the category.

Perhaps the most significant new entrant is the CME Group–FanDuel partnership, announced in August 2025. This combination brings together the world's largest derivatives exchange with one of America's largest sportsbooks, potentially creating an event contracts platform with unmatched liquidity and distribution.

The Sports Question: Prediction Markets or Gambling?

The expansion into sports has become the industry's most contentious frontier. The core question is deceptively simple: Is buying a contract on whether the Kansas Jayhawks will win the NCAA tournament a "prediction" or a "bet"?

The legal distinction matters enormously. Prediction markets regulated by the CFTC are classified as futures contracts on event outcomes, subject to federal commodity law. Sports gambling is regulated by individual states under frameworks established after the Supreme Court's 2018 Murphy v. NCAA decision.

This tension has produced a federal court split on whether the Commodity Exchange Act (CEA) preempts state gambling laws when applied to CFTC-regulated prediction markets. A New Jersey federal court sided with Kalshi in May 2025, granting a preliminary injunction that prevented the state from treating its sports event contracts as gambling. But as the National Law Review reported in August 2025, other courts have reached different conclusions, creating legal uncertainty.

The CFTC itself has entered the fray on the federal preemption side. In an extraordinary move, the CFTC sued Arizona, Connecticut, and Illinois in April 2026, challenging those states' attempts to regulate prediction market platforms under state gambling statutes.

Key insight: The sports prediction market question isn't just about semantics — it determines which regulators have jurisdiction, what taxes apply, and whether platforms need state-by-state gambling licenses or a single federal CFTC registration.

Tax Implications: An Unresolved Wrinkle

The tax treatment of prediction market contracts remains a significant open question. KPMG published an analysis in May 2025 exploring the potential tax implications for CFTC sports event futures contracts, highlighting the ambiguity.

The central issue involves 26 U.S.C. § 4401, which imposes a federal excise tax on wagers. If sports event contracts are classified as wagers rather than futures contracts, platforms and participants could face substantial tax liabilities. CFTC-regulated futures are typically taxed under the favorable 60/40 rule (60% long-term, 40% short-term capital gains), while gambling winnings are taxed as ordinary income with different reporting requirements.

This unresolved question has major implications for both platform economics and participant returns.

Ethical Boundaries and Content Moderation

As prediction markets scale, they increasingly face questions about what should be tradeable. In April 2026, Polymarket removed contracts related to a potential U.S. service member rescue mission in Iran after Congressman Seth Moulton and others criticized the markets as morally objectionable.

This incident highlights a fundamental tension in prediction markets: the same mechanism that makes them valuable as information aggregation tools — financial incentives for accurate forecasting — can appear ghoulish when applied to life-and-death scenarios. Platforms are developing content policies, but no industry-wide standards exist.

Similarly, markets on geopolitical events like Strait of Hormuz traffic disruptions (traded on both Kalshi and Polymarket in early 2026) sit in a gray area — genuinely useful for hedging and forecasting, but potentially uncomfortable in their commodification of conflict.

The Road to $1 Trillion

Bernstein's projection that prediction markets could reach $1 trillion in annual volume by 2030 may sound ambitious, but the structural pieces are falling into place:

• Regulatory clarity is improving, with the CFTC actively defending federal jurisdiction over event contracts
• Distribution is expanding through partnerships with Robinhood, Webull, FanDuel, and MLB
• Institutional infrastructure is maturing, with CME Group's entry bringing derivatives-grade clearing and risk management
• New market categories — sports, weather, geopolitics, economic indicators — are dramatically expanding the addressable audience
• The CFTC is actively approving new DCMs, increasing competition and innovation

However, significant risks remain. The federal court split on state preemption could result in a patchwork of regulations. Congressional action — either supportive legislation or restrictive gambling laws — could reshape the landscape overnight. And ethical controversies around sensitive markets could trigger political backlash.

What to Watch

The prediction market industry is at an inflection point. The next 12–18 months will likely determine whether these platforms become a permanent feature of the financial landscape or face regulatory retrenchment. Key developments to monitor include resolution of the federal–state jurisdictional split, potential Congressional legislation on event contracts, the launch of the CME Group–FanDuel platform, and whether the IRS issues guidance on the tax treatment of event contracts.

For traders, researchers, and market observers, prediction markets have never been more accessible, more liquid, or more consequential. The question is no longer whether they'll exist — it's how large they'll grow and who will control them.
