Nine. That is how many times Sydney Sweeney says the word "sports" in the roughly one-minute ad that Novig released on Wednesday 9 September, according to ABC News. She says it while mock-swinging a golf club, holding a hockey stick, leaning on a pool table and hanging from a basketball hoop, wearing very little beyond the equipment. The point, per Front Office Sports, is that Novig trades sports and only sports, unlike Kalshi and Polymarket, which will also sell you a contract on the Fed, the weather or the Oscars. The word landed. So did the backlash.
One day earlier, on Tuesday 8 September, Polymarket had launched its own campaign, a 60-second spot called "Polymarket HQ" fronted by LeBron James alongside Derek Jeter and Eli Manning, with Spike Lee, Sue Bird, Rajon Rondo, Reggie Bush, Richard Sherman, Alexandra Daddario, John Leguizamo and Craig Robinson filling out a fictional office building where every floor is a trading category (Northeast Times, Casino.org). Two campaigns, one week, both timed to the NFL opener, both under fire within 48 hours. If you have been wondering why every timeout during Week 1 looked like a prediction market commercial, this is the piece. If you are still working out where these apps sit next to a sportsbook, our guide to what happens when Kalshi gets switched off in your state covers the basics.
A primer for the bettor who skipped the CFTC paperwork
A prediction market is an exchange, not a book. You buy a "yes" or "no" contract priced between $0.01 and $0.99, the price is the market's implied probability, and if you are right the contract settles at $1. Nobody sets a line against you; the other side of your trade is another user. These exchanges are regulated federally by the Commodity Futures Trading Commission (the CFTC, the agency that oversees US futures markets) as Designated Contract Markets, which is why they run in states that have never legalised sports betting. Novig received its designation on 16 June 2026 and went live nationwide on 4 August, per its own press release and RotoWire. Polymarket's US entity, QCX LLC, has held a CFTC designation since 9 July 2025, per the CFTC's filings register, after Polymarket bought the exchange for $112 million (PR Newswire).
Why a bettor should care: the contract price is the whole market. A "yes" at $0.62 is the equivalent of a -163 (1.61) moneyline with zero hold, before whatever fee the exchange charges. Whether that beats your book's -110 (1.91) each way, which carries 52.4% + 52.4% = 104.8% implied and a 4.5% hold, depends entirely on the spread and the fee. Novig says it is commission-free "at the moment," in the CEO's words to RotoWire, which is a phrase worth remembering.
Two campaigns, side by side
The athletes did not laugh
Ariarne Titmus is an Australian swimmer with four Olympic golds and eight Olympic medals across Tokyo and Paris, who retired in October 2025 (Wikipedia). She posted on Instagram Stories: "I can't describe how infuriated I feel when I watch this," and then, in the line that has been quoted everywhere since, "How do we live in a world where monetising a woman's body and sexualising women's sport is still a thing?" (ABC). Front Office Sports carries the longer version: "Not only is it a kick in the face to every woman who has dedicated her life to perfecting her craft, but every woman who enjoys sports for what it really is."
She was not alone. Fellow swimmer Lani Pallister wrote she had "truly no words." Hockeyroos goalkeeper Jocelyn Bartram called it "so out of touch." British sprinter Amy Hunt used a post-race interview to say, "Sydney Sweeney, this is what women in sport look like." American gymnast Gracie Kramer posted a training reel captioned "idk what Sydney Sweeney was doing, but this is what a woman in sport looks like," which turned into its own trend. Sweeney's reply, per ABC, was wordless: she reposted images from ESPN's Body Issue, the magazine's long-running series of nude portraits of elite athletes. Novig did not respond to Front Office Sports' request for comment on the athletes, though Fortinsky told the outlet more Sweeney spots are coming.
LeBron's problem is different
Nobody accused Polymarket of bad taste. The objection is that an active NBA player is fronting a platform where users trade contracts on NBA games, including his own. Awful Announcing's Matt Yoder called the cast "a who's who of disappointing sellouts" and wrote that "prediction markets are ripe for corruption and predatory behavior" (via Yahoo Sports). The Philadelphia Inquirer noted the NBA has no policy stopping players partnering with prediction markets, unlike the NFL and PGA Tour, which prohibit such deals, and that the NBA, MLB and their players' unions had previously asked the CFTC to bar athletes from trading on their own leagues (Inquirer). Polymarket declined to give the Inquirer details of the deal. Casino.org reports LeBron's previous DraftKings arrangement expired in the middle of the summer, so the move from book to exchange took roughly two months.
Why the money is being spent now
Because Week 1 of the NFL is the biggest customer-acquisition window in American gambling, and the exchanges just proved they can fill it. Aldrin Research, cited by Covers, tracked more than $3 billion in prediction market volume across Week 1, with $2.88 billion on Sunday 13 September alone. Kalshi took $510.9 million of Sunday's total, a 76% share; DraftKings Predictions hit an all-time high of $139.8 million; Novig did $69.1 million; Robinhood's exchange did $40.2 million on NFL markets. Kalshi's CEO summed it up as "NFL week 1 is equal to a US election."
The books noticed. H2 Gambling Capital, reported by Covers, projects the first year-on-year decline in NFL handle since legalisation, 0.8%, and puts prediction market consumer handle at 8 to 11% of sportsbook handle in competitive states. Flutter's US marketing spend rose 61% to $353 million and DraftKings has earmarked $200 to $300 million for prediction markets, per Legal Sports Report. Everyone is buying the same Sunday.
The bit the ads leave out
Kalshi and Polymarket accept customers from 18, not 21, which H2 identifies as one of the main reasons volume is migrating from books to exchanges; Novig, notably, set its own floor at 21 (FishDuck). The legal map is also still moving: a Manhattan federal judge refused on 8 July 2026 to stop New York enforcing its gambling laws against Kalshi (Courthouse News), and New Jersey has asked the Supreme Court to hear its case. None of that appears in a 60-second spot with Spike Lee in it. If you want to compare a contract price against a sportsbook line before you trade, the odds converter turns cents into American odds in one step.
