Polymarket and Kalshi Expand Political Donations in 2026

Prediction market operators polymarket and Kalshi, along with their founders, have donated at least $5 million to Republican and Democratic political groups during the current election cycle, highlighting the industry’s growing efforts to engage with policymakers as regulatory pressure intensifies across the United States.

Campaign finance records and a private remittance document reviewed by Reuters show that the companies’ political spending has increased sharply compared with the 2024 election cycle, when they began attracting widespread attention. The contributions come as Prediction Markets face legal challenges from state authorities and growing scrutiny from federal lawmakers over concerns about insider trading, election betting and national security.

The companies have so far directed approximately $2.7 million to Republican groups, with Democrats receiving the remainder. However, the overall distribution could change as additional campaign finance disclosures become available before Election Day.

More than one-third of the combined contributions went to state-level political groups supporting candidates for governor, attorney general and state legislatures, according to an analysis by the Center for Political Accountability (CPA), a nonprofit focused on political spending transparency.

Prediction Market Companies Increase Political Spending

The combined $5 million in contributions represents a significant expansion of political engagement by Polymarket and Kalshi. Although their spending remains relatively small compared with contributions from the cryptocurrency and sports betting industries, the increase signals that prediction market operators are paying greater attention to the political decisions that could shape their future.

Prediction markets allow users to trade contracts tied to the outcomes of events, including elections, sporting competitions and government announcements. The prices of these contracts can reflect market participants’ collective expectations about the likelihood of particular outcomes.

Polymarket and Kalshi gained prominence during the 2024 US presidential election after their markets attracted attention for signalling Donald Trump’s victory in ways that differed from some traditional polling indicators.

The industry’s growing profile has brought increased scrutiny from lawmakers and regulators. Questions surrounding the legal status of event-based contracts, the boundaries between financial trading and gambling, and the possibility of trading on confidential information have become increasingly important to the companies’ operations.

David Primo, a political science professor at the University of Rochester in New York, said the industry was navigating an uncertain regulatory environment.

He argued that companies needed to engage with elected officials because decisions made by policymakers could significantly affect their ability to operate.

The donations therefore reflect a broader effort by prediction market companies to establish relationships with politicians and participate in discussions over the rules governing their businesses.

Kalshi Says Political Donations Are Not Partisan

Kalshi’s head of federal government relations, John Bivona, said the company’s complete disclosures by Election Day would show that its political contributions were distributed approximately evenly between Republicans and Democrats.

Bivona argued that regulation designed to protect consumers while allowing prediction markets to develop in the United States should not be treated as a partisan issue.

His comments come as the industry faces pressure from different political directions. While the Trump administration has generally supported prediction markets, some congressional Republicans have raised concerns about betting on elections. Democrats have also introduced several proposals intended to restrict certain types of prediction market activity.

Polymarket did not directly address questions about its Political Donations. A company spokesperson said the business engages with people across the political debate and welcomes discussions with anyone interested in understanding its platform.

The companies’ efforts to engage with both parties reflect the importance of federal and state policy decisions to their long-term prospects. Regulatory changes could affect which contracts they can offer, how their platforms operate and whether they can expand into additional markets.

Polymarket CEO Shayne Coplan Broadens Republican Contributions

Polymarket Chief Executive Shayne Coplan, who had previously donated almost exclusively to Democratic candidates and causes, has broadened his political giving during the current election cycle.

Campaign finance records show that Coplan and Polymarket have collectively directed approximately $1.3 million to Republican committees and candidates while continuing to support Democratic groups.

The contributions include donations to the Republican National Committee, a super political action committee supporting House Republicans and V-PAC, a super PAC backing Ohio Republican gubernatorial candidate Vivek Ramaswamy.

A separate contribution also highlights the role of organisations that do not publicly disclose their donors. According to a private remittance document reviewed by Reuters, Blockratize Inc, the company operating Polymarket, transferred $1 million to House Majority Forward during the summer.

House Majority Forward is a Democratic nonprofit that works to elect Democrats. Organisations operating under certain tax-exempt structures can receive political funding without being required to publicly identify their donors, a practice commonly associated with so-called dark money.

The $1 million contribution had not previously been reported, according to Reuters. Representatives for House Majority Forward and the Republican fundraising organisations either declined to comment or did not respond to requests for comment.

The donation highlights the difficulty of determining the full extent of political spending when contributions pass through organisations that are not required to disclose their financial backers.

Kalshi Founders Direct More Money Towards Republican Causes

Kalshi founders Luana Lopes Lara and Tarek Mansour have also increased their political contributions during the current election cycle.

Reuters could not identify political contributions by the founders in publicly available campaign finance records from previous election cycles. By early October, however, the pair had donated at least $1 million, with approximately 72% directed towards Republican causes and candidates.

The contributions add another dimension to the industry’s growing political involvement. While the companies themselves are seeking to influence discussions about regulatory policy, donations from their founders demonstrate that individual executives are also participating in the political process.

The overall figures suggest that prediction market operators are expanding their engagement beyond federal politics. State-level elections have become particularly relevant because state officials and legislatures can influence whether certain contracts are permitted and how event-based trading is classified under local law.

State-Level Donations Grow Amid Legal Battles

Polymarket and Kalshi are facing legal challenges from state gaming authorities, attorneys general and Native American tribes seeking to prevent the companies and other operators from offering sports-related contracts.

The challengers argue that these products constitute gambling and should therefore fall under state gaming laws and regulatory oversight. The companies maintain that their contracts are financial instruments subject to federal oversight rather than conventional gambling products regulated by individual states.

The dispute has created significant uncertainty for the industry, particularly as regulators and courts consider how existing laws apply to markets built around the outcomes of real-world events.

State-level political groups have consequently become an important destination for contributions. These organisations support candidates for offices that may influence gaming policy, enforcement priorities and the legal environment in which prediction markets operate.

According to the CPA analysis, contributions to state-level groups have accelerated over the past 12 months and have so far marginally favoured Democrats.

Kalshi has contributed nearly $1.5 million to these organisations, with its donations divided approximately evenly between the two parties. Polymarket has contributed nearly $250,000 to two Democratic groups and one Republican group, the analysis showed.

These contributions could help the companies develop relationships with political figures whose decisions may affect their business activities. However, the donations do not by themselves establish that any particular politician will support the companies’ preferred regulatory approach.

Political Access Becomes Increasingly Important

Jeanne Hanna, vice president for research at the Center for Political Accountability, said the slight preference for Democratic groups at the state level could reflect expectations about the party’s prospects in state elections.

She also noted that political organisations supporting state-level candidates can provide businesses with opportunities to build relationships with policymakers.

Hanna said political fundraising can operate through membership structures in which larger contributions provide donors with greater access to political figures.

For prediction market companies, these relationships may be particularly valuable because the legal and regulatory framework remains unsettled. Discussions with lawmakers can help businesses communicate their positions on proposed legislation and explain how they believe their platforms should be regulated.

Nevertheless, political engagement does not eliminate the possibility of stricter oversight. Regulators can continue pursuing legal action, and lawmakers from either party may support restrictions depending on their views about consumer protection, gambling rules, election integrity and financial market supervision.

Federal Scrutiny Adds to Regulatory Uncertainty

Alongside state-level legal disputes, prediction markets are facing increasing attention from federal lawmakers concerned about insider trading and potential national security risks.

One concern is whether traders could use confidential information to profit from contracts linked to political decisions, government announcements or other sensitive events. Such concerns have increased calls for clearer safeguards and stronger oversight as prediction markets expand their range of offerings.

Election betting has also become politically contentious. Supporters of prediction markets argue that trading can aggregate information and provide a real-time indication of market expectations. Critics have raised concerns about the risks of wagering on elections and whether certain contracts should be permitted.

The regulatory debate could determine how broadly prediction markets can operate in the United States and which categories of events they can offer to customers.

For Polymarket and Kalshi, the challenge is to navigate overlapping federal and state requirements while responding to political concerns that do not always align across party lines.

What the Donations Mean for the Prediction Market Industry

The increase in political contributions marks a new phase in the development of prediction markets in the United States. As the companies grow more prominent, their interests increasingly intersect with decisions made by Congress, federal regulators, state legislatures and gaming authorities.

The distribution of donations across Republican and Democratic organisations suggests that the industry is seeking relationships across the political spectrum rather than relying exclusively on one party. However, the contributions reported so far do not represent a complete picture of all political spending that may be disclosed during the election cycle.

The industry also faces an important distinction between building political relationships and securing favourable regulatory outcomes. Contributions may help companies participate in policy discussions, but the ultimate direction of regulation will depend on legislation, regulatory decisions and court rulings.

As the election approaches, further disclosures could provide a clearer picture of how prediction market companies and their founders are allocating political funding. Meanwhile, ongoing legal disputes and federal scrutiny will remain central to determining the industry’s future in the United States.

The coming months are likely to be important for Polymarket and Kalshi as they attempt to expand their businesses while defending their interpretation of the rules governing event-based trading. Their growing political spending underscores how regulatory uncertainty has become a central concern for an industry that has rapidly moved into the national spotlight.
