Polymarket news is trending after the South Korean media regulator raised concerns that the platform’s winner-take-all markets could create an illegal gambling environment. The move adds to growing pressure on prediction markets in many countries, as regulators weigh how these platforms affect users.
Polymarket News: South Korea Blocks Polymarket Access
South Korean users’ access to Polymarket has been blocked after the Korea Communications Standards Commission (KCSC) voted on August 18 to restrict the platform. The regulator said Polymarket’s markets on politics, elections, sports, and weather could encourage gambling because users take positions on outcomes and stand to win or lose based on the result.
The decision puts Polymarket under another major regulatory challenge. It also follows similar moves in other countries. France blocked access to Polymarket from July 16, saying the platform could expose users to massive losses or create a risk of betting manipulation. Australia and Germany also blocked access in August and September 2025, respectively.
The South Korean action focuses on how the platform operates its markets. Polymarket has argued that its structure is non-custodial and peer-to-peer. It also says smart contracts mean the company does not directly control user funds.

However, the regulator’s decision shows that the way a platform handles user funds is not the only issue authorities may consider. The markets offered, the rules around trading, and the possible effect on users can also draw attention.
What The Polymarket News Means
The Polymarket ban in South Korea could make it harder for users in the country to access the platform and participate in its markets. More importantly, the decision adds to the list of countries that have taken action against Polymarket over concerns linked to betting and market activity.
The dispute also raises a broader question about prediction markets. Polymarket operators manage and control the overall platform, including opening markets and setting trading rules. The platform also generates economic profits by collecting transaction fees in an environment where users deposit, withdraw, and settle funds through cryptocurrency systems.
That setup has become part of the debate over how Polymarket should be treated. While the company says users retain control through its non-custodial structure, regulators can still look at the wider platform and how its markets work.
For Polymarket, the South Korea decision therefore adds another access problem at a time when regulators in different markets are taking a closer look at prediction platforms. The effect will depend on whether other countries take similar steps.
The ruling also raises questions about how prediction markets will be treated when their trading systems cross into gambling rules.
Polymarket Faces Prediction Markets Competition From Kalshi
The South Korea Polymarket news also comes as competition in the prediction market space has become much tougher. A recent post by Wu Blockchain said Kalshi had moved from less than 10% of the crypto volume market share to more than 92% in eight months.
That shift highlights how quickly the balance between the two platforms may have changed. The post described the situation as a major setback for Polymarket, while also crediting Kalshi for making strong gains.
The competition gives Polymarket another issue to deal with beyond regulation. It now faces pressure from authorities in some markets while competing with a platform that has gained a much larger share of crypto trading volume, according to the figures shared in the post.
For now, South Korea’s decision adds to the pressure around Polymarket. The platform has defended its non-custodial, peer-to-peer model, but regulators are looking at the markets themselves and the risks they believe those markets may pose. With competition from Kalshi also growing, Polymarket faces a difficult period on both regulatory and market fronts.
