are other sub- clauses that define a swap as an “option” that hinges on “1 or more interest or other

rates, currencies, commodities, securities, instruments of indebtedness, indices, quantitative

measures, or other financial or economic interests or property of any kind” or an exchange of “1

or more payments based on the value or level of 1 or more interest or other rates, currencies,

commodities, securities, instruments of indebtedness, indices, quantitative measures, or other

financial or economic interests or property of any kind.” 7 U.S.C. § 1a(47)(A)(i), (iii).

Kalshi contends that its gaming devices fit the definition of 7 U.S.C. § 1a(47)(A)(ii). ECF

fina ncial, economic, or commercial consequence,” as used in sub -clause (ii), refers to the company

it keeps in sub-clauses (i) and (iii) – consequences that directly affect “rates, currencies,

commodities, securities, instruments of indebtedness, indices, [or] quantitative measures. ” The

outcome of a sporting event does not satisfy this requirement.

Canon Against Superfluity.

Even if noscitur a sociis is ignored, calling Kalshi’s gaming devices “swaps” would violate

the canon against superfluity. Under this canon, courts are “obliged to give effect, if possible, to

every word Congress used.” United States v. Weiss , 52 F.4th 546, 552 (3d Cir. 2022) (quotation

omitted). However, if “event or contingency associated with a potential financial, economic, or

commercial consequence” were so broad as to cover events with attenuated financial, economic,

or commercial connections, then all the other sub- clauses defining “swap” would be superfluous.

For example, a contract that hinges on “currencies” or “commodities” under clause (i), is also

associated with “financial, economic, or commercial consequences” under clause (ii) . If one

considers Kalshi’s sports gaming contracts “swaps,” the remainder of the definition is rendered

superfluous.
