California’s proposed billionaire wealth tax faces unfavorable prediction-market pricing ahead of the Nov. 3 vote. Both Polymarket and Kalshi favor rejection of Prop 40, according to Action Network.

The measure would impose a one-time 5% wealth tax on billionaires. The report, published Oct 14, 2026, at 2:54 AM ET, places passage firmly as the less likely outcome on both venues.

How the two markets compare

On Polymarket, Yes is priced at 30c and No at 71c. Kalshi assigns a lower price to passage, with Yes at 26c and No at 74c.

The venues therefore agree on the favored outcome, while Kalshi’s pricing is more negative toward the proposal. These figures describe the reported market snapshot, not a vote result.

What it means for prediction markets

• Rejection is favored on both exchanges: No prices of 71c on Polymarket and 74c on Kalshi show a consistent directional view.
• Passage remains a minority-priced outcome: Yes stands at 30c and 26c, respectively, rather than being priced out entirely.
• Nov. 3 is the key electoral date: The contracts concern whether California voters approve the proposed one-time 5% billionaire wealth tax.

The US Commodity Futures Trading Commission (CFTC) is pursuing two regulatory measures that distinguish prediction-market contracts from conventional gambling. Announced on October 9, the package combines an interim final rule excluding casino-style gambling from the definition of a swap with a proposal expressly covering event contracts, according to Sumsub.

Two measures, different legal status

The gambling exclusion becomes effective when published in the Federal Register. It removes sportsbook wagers and casino games from the swap definition, codifying what the CFTC describes as its existing view rather than announcing a new approach to those products.

The event-contract measure, by contrast, remains a proposal. It would explicitly place contracts tied to sports, politics, cultural events and weather within the swap definition. According to Sumsub, the agency says the trade already recognizes these instruments as swaps and that the proposed language would reduce uncertainty about their classification.

Selig said these contracts are commodity derivatives governed by the Commodity Exchange Act and subject to the CFTC’s exclusive jurisdiction. That is the agency’s stated jurisdictional position; the proposed classification change has not yet taken effect.

Regulatory scrutiny extends beyond the US

The CFTC is inviting written comments on both measures through Regulations.gov. For prediction-market participants, the distinction between an effective exclusion and a proposed inclusion is central to understanding the package’s current status.

Internationally, prediction markets have drawn scrutiny over illegal gambling, manipulation and insufficient consumer safeguards. According to Sumsub, platforms have encountered bans or blocking orders in Singapore, France and Argentina. Dutch authorities have also ordered Polymarket to cease offering unlicensed gambling or risk penalties.

What it means for prediction markets

• The proposal is not a final rule. Contracts concerning sports, politics, culture and weather would be explicitly included in the swap definition if the proposed change takes effect.
• The gambling exclusion has a separate trigger. Its effective date depends on Federal Register publication, not the October 9 announcement.
• Product classification is the key distinction. The CFTC is separating sportsbook wagers and casino games from event contracts it regards as derivatives.
• US developments do not settle overseas treatment. The reported restrictions abroad underscore the different regulatory approaches facing prediction-market platforms.
