Chicago officials are moving to close what they see as a growing ethical loophole by prohibiting city employees and elected officials from using confidential government information to profit on prediction-market platforms such as Kalshi and Polymarket. The proposed ordinance, which unanimously advanced from the City Council’s Ethics and Government Oversight Committee, would explicitly ban the use of nonpublic information to place or assist others in placing wagers on government actions, elections, zoning decisions, investigations, and other events that could be influenced by insider knowledge. Supporters argue the measure is necessary because prediction markets have expanded far faster than government ethics rules, creating new opportunities for public officials to monetize privileged information. From a conservative perspective, the proposal underscores a broader principle: government employees entrusted with confidential information should never be permitted to convert that information into personal financial gain, regardless of whether the vehicle is a stock trade or a prediction market. At the same time, the ordinance focuses on punishing misuse of insider information rather than outlawing prediction markets themselves, preserving the distinction between legitimate financial innovation and public corruption.

Key Takeaways
- Chicago is seeking to update its ethics code to explicitly prohibit city employees and officials from using confidential government information to profit through prediction-market platforms such as Kalshi and Polymarket.
- The proposal reflects growing national concern that rapidly expanding prediction markets present insider-trading risks similar to those long associated with securities markets, prompting both governments and private employers to tighten restrictions.
- Rather than banning prediction markets outright, policymakers are increasingly focusing on preventing conflicts of interest and protecting public trust by ensuring government employees cannot monetize privileged information.
In-Depth
Chicago’s proposed ordinance is less about gambling than it is about preserving public confidence in government. Public officials routinely have access to information that markets value long before it becomes public—from zoning decisions and contract awards to investigations and policy announcements. As prediction markets expand into virtually every corner of public life, the opportunity for abuse naturally expands with them.
The measure recognizes a simple reality: ethical standards should evolve alongside technology. Existing ethics laws already prohibit city employees from using confidential information for personal gain, but supporters contend that explicitly addressing prediction markets removes any ambiguity. That clarity matters because platforms allowing wagers on political, economic, and governmental events have grown rapidly while regulators continue to determine how they fit within existing financial and gambling laws.
The issue extends well beyond Chicago. Illinois has already imposed similar restrictions on state employees, and major financial institutions have begun limiting or prohibiting employee participation in sensitive prediction markets over concerns about insider information and reputational risk. That convergence suggests the concern is becoming a mainstream compliance issue rather than a partisan debate.
Ultimately, the proposal reflects a commonsense conservative principle: public service is a public trust. Government employees should never be in a position to profit from information acquired through taxpayers’ confidence. If prediction markets are to continue growing as legitimate financial tools, they must operate under rules that discourage corruption and reinforce the integrity of both government and the marketplace.
