Novig Sets Its Age Floor at 21 and Writes the Rules Down Before Anyone Makes It

Novig, a sports prediction market that launched last week and did $18 million in trading volume on its first day, has put a "responsible trading framework" into its exchange rulebook ^[1][2]. The substance is a minimum age of 21 rather than the 18 that Kalshi and Polymarket allow, plus marketing restrictions, and it arrives while the company is simultaneously suing four states over their gambling laws ^[3][4][9].

Three years of age floor is the whole differentiator on eligibility ^[5]. CEO Jacob Fortinsky, who is 28, told WIRED the decision responded to "valid concerns" about younger participants' susceptibility to risky behavior, including lobbying from the NCAA and other professional groups ^[6][7]. He expects "a broader reckoning coming with the younger traders," a group he describes as "particularly susceptible to irresponsible behavior and financial ruin" ^[8].

The rest of the framework is a list of things Novig will not do: no marketing to minors, no ads claiming there is no risk, no ads pitched at a prospective customer's money troubles ^[10]. Operationally this looks like using TikTok's over-21 targeting setting ^[11]. Fortinsky frames it as positioning Novig as a "serious, legitimate financial product," and says some competitors "have been seen as being a little bit more cavalier in certain regards." He declined to name them ^[12][13].

Read the cost side. Barring 18-to-20-year-olds and declining to run ads that promise no risk is a small revenue sacrifice against the alternative, which is having those rules written for you by a state legislature or a federal regulator with less interest in your unit economics. Novig only lists sports markets, so it skips the contested political territory like US elections and the Iran war ^[14]. That narrowness is also its exposure: if sports event contracts are banned, Kalshi and Polymarket lose the majority of their action, and Novig loses everything, because sports is all it does ^[15].

Which explains the aggression. Within three days of launching, Novig sued New York, Massachusetts, New Mexico and Washington, seeking to block them from applying state gambling law to what it says is a federally regulated exchange ^[4][16]. Sports betting attorney Daniel Wallach called the complaints a "great marketing strategy" and a way of announcing arrival ^[17]. So far the courts have not obliged: a New York judge denied Novig's temporary restraining order because granting it would undermine an earlier decision in a case against Kalshi, and Wallach says it is "increasingly looking more positive for the states" ^[18][19]. Dozens of these fights are running at once, with states suing Kalshi, Kalshi countersuing, and the CFTC suing several states over jurisdiction ^[20][21].

The reputational cost is real even at 21-plus. When the New York Mets announced a partnership with Novig, the team drew a flood of social media criticism, including one post reading "This is vile" ^[22].

Watch three things: whether Kalshi or Polymarket match the 21 floor once a state or Congress starts drafting, who actually audits Novig's rulebook commitments given no outside body is named as enforcing them ^[10], and how the jurisdictional question moves, since Wallach and other observers expect it to reach the US Supreme Court before anything is settled ^[23].
