Mandatory Disclosure Rules for Polymarket, Kalshi Ads by X

Social media platform X is set to implement mandatory disclosure features for advertisements from prediction market platforms like Polymarket and Kalshi. This move, announced on February 21, 2026, is crucial for enhancing transparency and distinguishing sponsored content from organic posts.

What Happened

X announced it will introduce specialized disclosure features for paid promotions from prediction market platforms, such as Polymarket and Kalshi, by February 2026. Product Director Nikita Bier stated these features aim to improve transparency, allowing users to easily identify sponsored “betting odds” or “market projections.” Accounts failing to disclose partnerships or sponsored posts will face immediate suspension.

Why It Matters

This initiative follows a surge in prediction market activity, with Kalshi reporting over $1 billion in trading volume during the Super Bowl. As prediction markets grow, so do their advertising budgets, making transparency in these ads essential for compliance with federal advertising standards. This change also addresses concerns about “shadow lobbying” and manipulation of public opinion.

Investor Takeaway

Reactions and Competitive Context

Michael Selig, chairman of the CFTC, supports a permissive regulatory framework for prediction markets, likening them to traditional futures contracts. However, the close ties between these platforms and the current administration have raised political concerns. X’s standardized “Paid Promotion” tag aims to mitigate these issues.

What’s Next?

As the 2026 midterm elections approach, prediction market ads on X are expected to grow significantly. These platforms are becoming alternative news sources, with media outlets citing their odds as accurate reflections of reality. X’s new disclosure toolkit will include interactive elements for users to verify claims, aligning prediction markets with financial industry standards.

Investor Takeaway

X’s proactive approach to ad transparency could set a new standard in the digital economy, balancing rapid growth with regulatory scrutiny.
