Polymarket implements new fees and tightens insider trading protocols
The prediction market platform Polymarket has announced a profound restructuring of its business model, set to take effect on March 30, 2026. The main change lies in the expansion of its trading fees, which will no longer be limited exclusively to sports and cryptocurrency events but will encompass virtually all categories on the site, including politics, finance, technology, culture, and meteorology. This decision seeks to stabilize the company's revenue at a time of high volatility and international scrutiny of prediction platforms.
The new fee structure will maintain a probability-based pricing system, but with notable variations depending on the sector. While cryptocurrency markets will face the highest rates, reaching up to 1.8 percent for intermediate odds, the sports segment will retain a more competitive structure with a maximum of 0.75 percent. To incentivize liquidity, Polymarket will maintain its maker-taker model, offering rebates to users who provide depth to the market. Additionally, the platform will strengthen its loyalty program through daily USDC rewards, calculated based on the volume executed by each participant.
Alongside the fee changes, a referral program aimed at high-volume users will be launched. Those who trade a minimum of $10,000 will be able to generate links to earn 30 percent of the commissions generated by their direct referrals and an additional 10 percent for second-level referrals. This aggressive growth strategy is being implemented in parallel with a series of much stricter ethical controls, designed to clean up the platform's image after several controversial episodes linked to geopolitical conflicts.
Market integrity and the fight against leaks
Betting integrity has become a priority for Polymarket, which now explicitly prohibits three types of conduct to prevent unfair advantages. Any operation based on stolen or confidential information, the use of illegal leaks, and, fundamentally, the participation of individuals with the ability to directly influence the outcome of events will be restricted. These protocols attempt to mitigate criticism that arose after suspicious correct predictions on contracts regarding tensions between the United States and Venezuela, or recent attacks against Iran, where some users achieved millionaire profits by anticipating exact dates of military interventions.
The regulatory siege in Europe
This tightening of internal rules also responds to the strong pressure Polymarket faces on the European continent. During the first quarter of 2026, countries such as Hungary, Portugal, and Ukraine have blocked or banned its operations by classifying the activity as unauthorized betting intermediation. The most critical case is in the Netherlands, where the national regulator has threatened the company with weekly penalties of 420,000 euros if it does not cease its service offering immediately.
With these new compliance controls, the platform is trying to demonstrate that it can operate under standards similar to those of regulated financial markets. However, the technical challenge of blocking digital addresses in real-time and the decentralized nature of many of its processes remain points of friction with the gambling authorities of each country. The transition beginning at the end of March will define whether Polymarket manages to consolidate itself as a legitimate financial instrument or if it ends up operating exclusively in jurisdictions with more lenient regulations.
