Kalshi published an advertisement on January 23, 2025, with the headline that asserted:

11

“Sports Betting Legal in all 50 States on Kalshi,” which included the statement: “Breaking News:

You can now bet on sports in all 50 states with Kalshi.” Gouker article, supra page 2. These

12

13

statements are not susceptible to more than one reasonable interpretation; the only reasonable

14

interpretation is that Kalshi offers “sports betting” and that sports betting is “legal in all 50 states.”

15

These statements are literally false. First, states either criminally prohibit or strictly regulate sports

betting activity. See e.g. , Cal. Penal Code § 337a(1). Thus, on its face, sports betting is not legal

16

17

in all fifty states and is not legal in California. Second, at the federal level, IGRA and the Wire

18

Act, 18 U.S.C. § 1084, prevent such conduct. Kalshi’s assertion that its “sports betting” is “legal

19

in all 50 states” relies on the presumed preemptive force of the CEA, a caveat that cannot be

20

reasonably ascertained from the plain language of the advertisement. Significantly, Kalshi’s

21

contracts are not legal in all fifty states because, as shown above, Kalshi’s contracts do not comply

22

with the CEA, as they are presumptively contrary to the public interest and, pursuant to 17 C.F.R.

23

§ 40.11, Kalshi was prohibited from offering its gaming contracts to consumers.

24

Even if Kalshi’s advertisements were not facially false, they are false by necessary

25

implication. Under “the false-by-necessary-implication doctrine, ‘[i]f the words or images,

26

considered in context, necessarily imply a false message, the advertisement is literally false[,] and

no extrinsic evidence of consumer confusion is required.’” Suzie’s Brewery , 519 F. Supp. 3d at
