CONCISE EXPLANATION AND ANALYSIS OF THE PRODUCT AND ITS 

COMPLIANCE WITH APPLICABLE PROVISIONS OF THE ACT, INCLUDING CORE 

PRINCIPLES AND THE COMMISSION'S REGULATIONS THEREUNDER 

Pursuant to Commission Rule 40.2(a)(3)(v), the following is a concise explanation and analysis 

of the product and its compliance with the Act, including the relevant Core Principles, and the 

Commission's regulations thereunder. 

I. Introduction 

The “Will a <hurricane_category> hurricane hit Hatteras Island?” Contract is a contract 

relating to maximum sustained wind speeds of storms hitting Hatteras Island. After 

careful analysis, Kalshi (hereafter referred to as “Exchange”) has determined that the 

Contract complies with its vetting framework. 

In the last five years, Atlantic hurricanes have inflicted over $393 billion worth of 

damage in the United States. 1 Tropical storms and hurricanes can disrupt essential 

services and utilities like hospitals, water lines, and electricity, displace individuals, 

destroy homes, and lower property values of affected areas. Climate change may, 

scientists report, both increase the frequency of tropical cyclones and increase their 

severity. “Since 1975,” a 2013 study concludes, “there has been a substantial and 

observable regional and global increase in the proportion of Cat[egory] 4-5 hurricanes of 

25-30 percent per °C of anthropogenic (human-caused) global warming.” 2 Naturally, the 

larger the size of the hurricane, the larger the economic impact. The Contract allows 

affected individuals, businesses, and other investors to hedge the risk that a hurricane or 

tropical storm poses to their livelihood. 

Further information about the Contract, including an analysis of its risk mitigation and 

price basing utility, as well as additional considerations related to the Contract, is 

included in Confidential Appendices B, C, and D.

Pursuant to Section 5c(c) of the Act and CFTC Regulations 40.2(a), the Exchange hereby 

certifies that the listing of the Contract complies with the Act and Commission 

regulations under the Act. 

General Contract Terms and Conditions: The Contract operates similar to other event 

contracts that the Exchange lists for trading. The minimum price fluctuation is $0.01 (one 

cent). Price bands will apply so that Contracts may only be listed at values of at least 

$0.01 and at most $0.99. Further, the Contract is sized with a one-dollar notional value 

and has a minimum price fluctuation of $0.01 to enable Members to match the size of the 

contracts purchased to their economic risks. The Exchange has further imposed position 

limits (defined as maximum loss exposure) of $25,000 USD on the Contract. As outlined 

in Rule 5.12 of the Rulebook, trading shall be available at all times outside of any 

maintenance windows, which will be announced in advance by the Exchange. Members 

will be charged fees in accordance with Rule 3.6 of the Rulebook. Fees are charged in 

such amounts as may be revised from time to time to be reflected on the Exchange’s 

Website. A new Source Agency can be added via a Part 40 amendment. All instructions 

on how to access the Underlying are non-binding and are provided for convenience only 

and are not part of the binding Terms and Conditions of the Contract. They may be 

clarified at any time. Furthermore, the Contract’s payout structure is characterized by the 

payment of an absolute amount to the holder of one side of the option and no payment to 

the counterparty. During the time that trading on the Contract is open, Members are able 

to adjust their positions and trade freely. After trading on the Contract has closed, the 

Expiration Value and Market Outcome are determined. The market is then settled by the 

Exchange, and the long position holders and short position holders are paid according to 

the Market Outcome. In this case, “long position holders” refers to Members who 

purchased the “Yes” side of the Contract and “short position holders” refers to Members 

who purchased the “No” side of the Contract. If the Market Outcome is “Yes,” meaning 

that the maximum sustained wind speeds are at least <speed> in Hatteras Island between 

Issuance and <date>, then the long position holders are paid an absolute amount 

proportional to the size of their position and the short position holders receive no 

payment. If the Market Outcome is “No,” then the short position holders are paid an 

absolute amount proportional to the size of their position and the long position holders 

receive no payment. Specification of the circumstances that would trigger a Market 

Outcome of “Yes” are included below in the section titled “Payout Criterion” in 

Appendix A.
