Polymarket introduces mandatory KYC verification as regulators worldwide increase pressure, investigations, sanctions scrutiny, and restrictions on anonymous prediction trading.
Polymarket is the world’s largest prediction market platform. And right now, it is facing some of its biggest challenges yet. According to The Information, the platform is rolling out mandatory identity verification, also known as KYC or Know Your Customer, for all its traders. This decision did not come out of nowhere. It is a direct reaction to the increasing pressure from regulators, sanctions risks and serious legal concerns that are accumulating against the platform.

Why Is Polymarket Now Requiring Identity Verification?
Polymarket was a long time ago having very few barriers to entry. Anyone could register and begin trading on real-life events. But that open model is now causing serious issues.

Crypto prediction markets are beginning to be seen as unlicensed gambling by regulators worldwide. The label has significant legal implications. In addition, some users in certain areas have been discovering ways to use the site illegally.
The KYC rollout is also a continuation of the previous measures the platform has already implemented. Polymarket’s Market Integrity Rules were updated in March 2026 to officially prohibit wash trading, spoofing and insider manipulation. This new step is indeed a part of a larger initiative to achieve full compliance.
Which Countries Have Blocked Polymarket in 2026?
In 2026, the number of countries that have banned Polymarket has increased significantly. In late May 2026, Spain’s Ministry of Consumer Affairs banned both Polymarket and its rival Kalshi from its country’s websites. The reason cited was straightforward: No age control systems were in place and the platforms did not have proper identity verification.
However, Spain is not the only country. Other countries have also taken steps to limit or ban Polymarket this year, such as India, Indonesia, Brazil, Portugal, and Argentina. The increasing number of these shows that regulators around the world are growing impatient with platforms that enable anonymous trading on event-based markets.
How Are Some Users Still Getting Around the Restrictions?
Some users have managed to bypass the geographic restrictions and continue using Polymarket.Despite the geographic restrictions, some users have managed to access Polymarket. In restricted areas such as Russia, traders have been exploiting the platform’s restrictions by employing automated trading bots. In certain areas, like Russia, traders have been finding ways to circumvent the platform’s restrictions using automated trading bots.
This is a serious issue for Polymarket. These workarounds put the platform at risk of violating international sanctions. And that is a risk that no major platform can afford to ignore for long.
What Do US Regulators Want From Polymarket?
The pressure is not limited to overseas. The House Oversight Committee and the Commodity Futures Trading Commission (CFTC) have intensified their investigations into Polymarket in the U.S. Now, federal authorities are asking for detailed transaction records. They are interested in looking for insider trading and also want to know if the platform was complying with the KYC regulations.
It’s a very strong signal when both a congressional committee and a federal regulator are looking into your platform at the same time. It is a sign that Polymarket’s compliance is not sufficient for the US market.
What Does This Mean for Everyday Traders on Polymarket?
These changes will make a tangible difference to regular users. Traders will have to present government issued identification before they can wager on event contracts in the future. This involves proving their age, their identity and where they live.
It’s a massive change. Polymarket has always been an open access, decentralised platform. The introduction of compulsory ID checks brings it closer to the traditional financial services. That additional step will be a stumbling block for some users.
What Does This Mean for the Future of Crypto Prediction Markets?
Polymarket’s move is about more than just one platform. It marks a pivotal moment for the whole crypto prediction market sector. The era of trading without any identification, no borders, on real events seems to be over.
Platforms that fail to establish proper identity verification and sanctions screening systems in their systems have a straightforward option: comply or be banned. Polymarket is definitely opting for compliance. As more countries begin to impose restrictions, other platforms in this area will soon be forced to do the same.
