Polymarket, the prediction-market platform, rolled out a broadened fee model on March 30, expanding taker fees beyond crypto and sports to a wider array of categories. In the days that followed, metrics tracked by DefiLlama show a sharp rise in on-platform activity monetized through fees, with daily trading fees crossing the $1 million mark on Wednesday and Thursday. Revenue after incentives climbed to as high as $995,000 on Wednesday before easing to roughly $899,000 on Thursday. The shift underscores how Polymarket is recalibrating its economics to lock in ongoing investor interest amid intensifying regulatory scrutiny.

The broadening of the fee schedule coincides with a deliberate push to monetize activity more aggressively. Polymarket expanded taker fees to categories such as finance, politics, economics, culture, weather and tech, while keeping geopolitical and world events free of fees. The core idea appears to be extracting more value from routine trading activity, a move that aims to sustain liquidity and growth even as jurisdictions around the world tighten oversight of prediction markets. Data from DefiLlama illustrates the immediate impact: daily fees surged from about $363,000 on Monday to more than $1 million on midweek days, with revenue after incentives peaking at near $1 million on Wednesday before settling lower on Thursday.

Key takeaways

• DefiLlama data show Polymarket’s daily fees jumped from roughly $363,000 to over $1 million in the days after the March 30 fee overhaul, signaling a dramatic monetization shift.
• Revenue after incentives rose to as high as about $995,000 on one day, then moderated to around $899,000 on the following day, reflecting how the new fees translate into platform economics.
• The fee expansion added taker charges across more categories—finance, politics, economics, culture, weather and tech—while keeping geopolitical and world-events fees free.
• Regulatory pressure remains a core driver of strategy, with ongoing limits on access in multiple jurisdictions and actions by U.S. states, even as investor interest persists.

Regulatory pressure tightens across borders

The surge in Polymarket’s fees arrives amid a broader regulatory crackdown on prediction markets across Europe, North America and beyond. In Europe, the platform has faced mounting restrictions as regulators argue that it operates as an unlicensed gambling venue in several jurisdictions. Hungary and Portugal, for example, moved to block or limit access in January over licensing concerns and, in Portugal’s case, questions around political betting. These frictions complicate user acquisition and liquidity, even as demand for event-based markets remains visible among certain trader cohorts.

Other notable developments illustrate the global regulatory tension. In Argentina, a court order issued on March 17 ordered a nationwide ban on Polymarket, contending that the platform allowed users to place bets without sufficient identity and age verification, raising concerns about accessibility for underage users. Polymarket’s own geoblock information indicates the platform is currently blocked in 33 countries, a figure that underscores the cross-border compliance challenges faced by the operator. Kalshi, a competing prediction market, reports even broader restrictions, stating it is banned in 52 jurisdictions.

Across the United States, the regulatory environment remains unsettled. At least 11 states have taken legal action against prediction markets such as Polymarket and Kalshi, with cease-and-desist orders or new legislative proposals under consideration in several states. Despite these crackdowns, both platforms have signaled an ability to pursue expansion, with reports of potential large-scale fundraising rounds that could value each platform around $20 billion. The tension between growth ambitions and regulatory risk continues to shape the trajectory of the sector.

In late March, Polymarket and Kalshi introduced new trading restrictions aimed at curbing insider trading after criticism about well-timed bets and concerns about market integrity. The reform push signals a desire to bolster trust in event markets while navigating a landscape where regulators are increasingly vigilant about preemptive positions and information asymmetries.

Investor interest persists amid a risk-laden backdrop

The interplay between monetization, regulatory risk and investor sentiment remains delicate. The private investment narrative around Polymarket received a high-profile boost when Intercontinental Exchange, the parent of the New York Stock Exchange, reportedly invested about $600 million in Polymarket last week. The move underscores a sustained interest from large financial players in the potential of structured prediction markets, even as the sector contends with licensing, anti-gambling, and consumer-protection concerns in key markets.

On the funding side, both Polymarket and Kalshi are rumored to be exploring new rounds that could push their valuations into the tens of billions of dollars, highlighting a long-term belief among some investors that event-based markets can scale beyond their current regulatory envelopes. The ongoing push for expansion, paired with legal scrutiny, creates a dynamic where monetization levers, compliance, and user protection must co-evolve to maintain liquidity and participation.

As a matter of policy and practicality, March 24 saw explicit steps to address market integrity concerns through tightened trading rules, setting a precedent for how similar platforms might balance rapid growth with stronger oversight. The broader market will continue to watch how regulators respond to these shifts, whether geoblocking efforts intensify, and how exchanges balance revenue opportunities with responsible operator practices that protect users and maintain fair markets.

Readers should stay attentive to regulatory updates, particularly in Europe and the United States, where the legal status of prediction markets remains unsettled in several jurisdictions. The evolution of Polymarket’s fee model, alongside liquidity dynamics and enforcement actions, will likely shape how users engage with event-based markets in the coming months and whether investor appetite for large-scale funding rounds sustains the sector’s momentum.

What to watch next: regulatory clarity in key jurisdictions, the sustainability of elevated fee-driven revenue, and whether the ongoing confluence of large-cap investment and stricter market rules will redefine how forecast markets operate at scale.

Prediction market Polymarket’s recent fee expansion has started to affect its numbers, with daily fees and revenue climbing sharply in the days following a March 30 price overhaul. 

According to DefiLlama data, daily fees rose from about $363,000 on Monday to over $1 million on both Wednesday and Thursday, while revenue (the portion retained after incentives) reached as high as $995,000 on Wednesday before easing to about $899,000 on Thursday. 

The jump follows the rollout of a broader fee model on Monday, when the platform expanded taker fees beyond crypto and sports to categories including finance, politics, economics, culture, weather and tech, while keeping geopolitical and world events fee-free. 

The spike shows how aggressively Polymarket is monetizing trading activity to maintain continued investor interest amid regulatory scrutiny in the US, Europe and other countries worldwide. Last week, Intercontinental Exchange, the parent company of the New York Stock Exchange, invested $600 million in Polymarket.

Prediction markets face growing regulatory scrutiny

The fee and revenue spike comes as prediction markets, including Polymarket, face growing regulatory scrutiny across multiple jurisdictions.

In Europe, Polymarket has faced mounting restrictions, with Hungary and Portugal moving to block or limit access in January over concerns that the platform operates as unlicensed gambling. Regulators in both countries cited licensing issues and, in Portugal’s case, concerns around political betting.

On March 17, a court in Argentina ordered a nationwide ban on Polymarket, arguing that the platform allowed users to place bets without sufficient identity and age verification. The court said this meant that even children and adolescents could access the platform and place bets without any control. 

According to Polymarket’s website, the platform is currently blocked in 33 countries. Kalshi, on the other hand, reports that it’s banned in 52 jurisdictions. 

In the United States, at least 11 states have taken legal action against prediction markets such as Polymarket and Kalshi, with several issuing cease-and-desist orders or considering new legislation.

Despite regulatory crackdowns, Polymarket and Kalshi are looking to expand, with both reportedly exploring new funding rounds that could value each platform at around $20 billion.

On March 24, Polymarket and Kalshi introduced new trading restrictions to curb insider trading following criticism over well-timed bets and growing concerns around market integrity.
