Reuters reports at least $5m in Kalshi and Polymarket political giving

The reported total combines company and founder contributions as prediction markets contest state and federal oversight.

Kalshi, Polymarket and their founders have contributed at least $5 million to Republican and Democratic political groups during the current election cycle, Reuters reported on 22 October. Its account draws on campaign-finance records and a private remittance document reviewed by the news agency.[4]

Republican recipients received $2.7 million, with Democrats receiving the remainder. Reuters reported that just over a third of the combined spending went to state-level groups, citing the Center for Political Accountability. The total includes a $1 million Polymarket contribution to a Democratic nonprofit that does not disclose donors.[4]

The spending accompanies litigation over whether event contracts fall under federal derivatives oversight or state gambling rules. Political contributions do not establish the outcome of those cases or show that any particular official traded a decision for money.

Kalshi told Reuters that its complete election disclosures would show donations roughly balanced between the parties. Polymarket said it engages across the debate. Those responses help explain the companies’ positions; the published totals remain Reuters’ findings rather than an independent FX Brokers reconstruction of every underlying payment.[4]
