Wedgewood polling fraud tests Kalshi contract settlement rules

On October 20, Wedgewood polling admitted it had fabricated most of its election surveys. The admission arrived on the same day Kalshi's KXVHGCB-26OCT20 contract — a generic congressional ballot market tied to VoteHub's time-weighted average — was scheduled to resolve.

VoteHub is the designated source agency for a category of Kalshi contracts certified in September 2025. The certification document states that revisions to the underlying data made after expiration will not be accounted for in determining settlement value. VoteHub's head of data science, Zachary Donnini, confirmed that his organization graded Wedgewood a D and incorporated its polling anyway, after speaking with a Wedgewood representative.

The legal question this creates is narrower than it first appears, and also harder.

Kalshi's rulebook designates a fixed observation time — in the October series, 5:05 p.m. Eastern on the contract date. Settlement turns on what VoteHub's average reads at that moment, not on whether the underlying polling was accurate. The design is standard for event contracts: traders need a definitive reference, and post-settlement revisions would otherwise make finality impossible. The CFTC has long accepted this structure. Designated contract markets are permitted to write rules that fix a settlement methodology and insulate it from subsequent correction.

The harder problem is what the CFTC's oversight obligation looks like when the underlying source is compromised before settlement — not after. Wedgewood's fabrication was reported on October 20. The contract resolved on October 20. Whether VoteHub's average at 5:05 p.m. already reflected data now known to be false is not a hypothetical. It is the specific fact the rulebook's revision exclusion was never designed to address.

The Commodity Exchange Act requires designated contract markets to prevent manipulation and protect market participants. 7 U.S.C. § 5(b). The CFTC's core principles for contract markets, set out under 7 U.S.C. § 7, require that listed contracts not be readily susceptible to manipulation and that contract terms and conditions be based on a reliable price or value. VoteHub's own methodology document discloses that its Complete forecasting model incorporates Kalshi prices as an input — meaning the data source and the market it underlies are not fully independent.

I have seen enforcement staff reach for manipulation doctrine when a reference price is corrupted, even without evidence that any trader caused the corruption. The theory runs that a contract settled on a false input produces a transfer of value that the market's rules did not contemplate, regardless of intent. Whether that theory applies here depends on language in the current-series rulebook that has not been made public.
