Election Officials Across States Highlight Risks From Prediction Markets for 2026 Midterms

Election officials in multiple jurisdictions have raised alarms about prediction markets such as Kalshi and Polymarket, where participants place wagers on outcomes including party control of Congress, and how these platforms might affect public confidence in the 2026 midterms. An NBC News analysis examined trading activity that reached nearly $200 million in volume tied to midterm results, and officials point to issues around possible manipulation, mismatched expectations when actual results differ from market probabilities, and direct conflicts with state laws that ban election betting.

Current Landscape of Prediction Market Activity

Trading on these platforms has expanded rapidly in recent months, with users betting on specific congressional control scenarios and other election-related events ahead of the 2026 cycle. Data from the referenced analysis shows substantial financial interest in these markets, and that volume has drawn attention from administrators responsible for maintaining election integrity. Officials note that participants often treat market odds as predictive indicators, yet these figures reflect betting behavior rather than verified polling or turnout data.

States maintain longstanding prohibitions on direct election wagering, and prediction markets operate in a gray area that overlaps with those restrictions. Election workers in certain counties have received explicit instructions against participating in such betting, as administrators seek to prevent any perception of internal conflicts. Those measures include reinforced policies that bar staff from holding positions in markets tied to races they oversee.

Local Responses in Key Counties

Administrators in Los Angeles County and Delaware County have documented rising skepticism among observers during ballot processing stages, and they link part of that suspicion to widespread awareness of prediction market activity. Staff in these offices have implemented additional transparency steps during counting periods, while also reminding employees of existing rules against any form of election-related wagering. The steps aim to address concerns before they escalate into broader challenges to result certification.

Similar discussions have surfaced among officials in other regions preparing for 2026 contests, where market activity intersects with state-level restrictions. Figures from the NBC News review illustrate how trading concentrates on high-profile outcomes, and that concentration has prompted reviews of how such platforms interact with local statutes. Election offices continue to monitor developments while focusing on procedural safeguards already in place.

Concerns Over Public Perception and Manipulation

Potential divergence between market odds and final vote tallies represents one area of focus, because observers may interpret such gaps as evidence of irregularities rather than normal statistical variation. Officials have noted that heavy promotion of prediction market data in media coverage can amplify this effect, leading some members of the public to question processes that operate independently of betting activity. Training sessions in several counties now include segments on addressing questions from voters who reference market movements.

Manipulation risks receive attention as well, given that concentrated positions in thinly traded contracts could shift displayed probabilities without reflecting broader sentiment. State laws already prohibit election betting in many places, and regulators continue to examine whether existing enforcement tools cover newer platform models. Administrators emphasize that these markets function separately from official tabulation systems, yet they acknowledge the need to communicate that distinction clearly during the 2026 cycle.

Implementation of Worker Betting Bans

Counties have updated employee handbooks and conducted briefings to underscore prohibitions on election betting, and these updates align with longstanding statutes that predate the rise of digital prediction platforms. Workers receive reminders that participation could create both legal exposure and public relations complications during contested counts. The approach builds on prior ethics guidelines while responding to the specific visibility that prediction markets now receive.

Officials report that early feedback from staff indicates understanding of the rules, although some express curiosity about the scale of trading volume. Training materials stress that market activity occurs outside official channels and does not influence ballot handling or result reporting procedures. Continued reinforcement of these policies forms part of routine preparation for upcoming midterms.

Broader Implications for Election Administration

Coordination among state and local offices has increased as administrators share information about market developments and their potential effects on voter trust. Discussions focus on maintaining clear separation between betting platforms and official processes, while also preparing responses to inquiries that reference market data. Resources allocated to public communication have grown in some jurisdictions to cover these topics alongside traditional election education efforts.

Analyses of trading patterns continue to inform these preparations, and officials review available figures to identify which races attract the most attention on prediction platforms. That information helps prioritize outreach in areas where market activity could generate the most questions. The emphasis remains on documented procedures that govern every stage of ballot processing and certification.

Conclusion

Election officials continue to track prediction market activity while reinforcing existing safeguards and communication strategies ahead of the 2026 midterms. The concerns center on trading volume reaching nearly $200 million, possible manipulation vectors, perception gaps when results diverge from odds, and compliance with state prohibitions on election betting. Counties including Los Angeles and Delaware have taken concrete steps such as worker bans and added transparency measures. These actions reflect ongoing efforts to preserve confidence in established tabulation systems regardless of external market dynamics.
