Pa. lawmakers weigh ethics rules for political prediction market bets

Better Markets' Schiffrin says Kalshi and Polymarket risk rigging elections

Schiffrin's broadcast attack gives progressive lawmakers a ready-made soundbite for hearings on event-contract regulation. The election-rigging framing is sharper than the usual gambling critique and harder for platforms to rebut, since it alleges harm to democratic process rather than mere moral hazard. Kalshi and Polymarket now face three simultaneous narrative threats: CFTC branding rules, state gambling enforcement, and this new electoral-integrity line. The latter is the most dangerous in Congress, where both parties compete to protect election legitimacy. Platforms with heavy political contract volume — especially Kalshi's congressional and State of the Union markets — cannot easily pivot away. The next legislative hearing on prediction markets will likely feature Schiffrin's clip, forcing platform lobbyists to defend election contracts on substance rather than process. That raises the political cost of keeping them live.
