1

Concerning Kalshi’s advertising practices, Kalshi will not suffer any legitimate hardship

2

from the issuance of a preliminary injunction halting its false and misleading advertisements.

dissemination of false statements.” Pom Wonderful Ltd. Liab. Co. v. Purely Juice, Inc. , No. CV-

07-02633 CAS (JWJx), 2008 U.S. Dist. LEXIS 55426, at *42 (C.D. Cal. July 17, 2008). Requiring

6

a defendant to refrain from using false statements “... poses little, if any, harm to [the defendant].”

Id . (internal citations omitted) (quoting Sun Microsystems, Inc. v. Microsoft Corp. , 87 F. Supp. 2d

992, 998 (N.D. Cal. 2000)).

9

Kalshi has knowingly made false statements to consumers through numerous advertising

10

campaigns. The inconvenience arising from a court order directing Kalshi to cease false

11

advertising pales in in comparison to the harm incurred by the constitutional infringement of tribal

12

sovereignty and diversion of essential gaming revenue, which the Tribes rely upon to provide

13

essential services. The balance of hardships, therefore, weighs decidedly in favor of granting a

14

preliminary injunction.

Public Interest

16

In deciding what issues affect the “public interest,” courts have given considerable weight

to the carrying out of executive functions of the government as well as the intent of Congress. See

17

Winter, 555 U.S. at 24 (“In this case, the District Court and the Ninth Circuit significantly

18

19

understated the burden the preliminary injunction would impose on the Navy’s ability to conduct

20

realistic training exercises, and the injunction’s consequent adverse impact on the public interest

in national defense.”); see also Starbucks Corp. v. McKinney , 602 U.S. 339, 362 (2024) (“When

21

22

addressing the public interest, courts must defer to Congress’s articulation of that interest in the

23

[Act] itself.” (citing 29 U.S.C. § 151 (“It is . . . the policy of the United States to . . . encourag[e] .

24

. . collective bargaining and . . . protec[t] the exercise by workers of full freedom of association,

self-organization, and designation of representatives of their own choosing . . . .”).); Virginian Ry.
