Polymarket mails a daily news roundup that links each story to a market on it
Polymarket's daily dispatch summarises the day's news and links out to its own yes/no markets, part of a broader push by prediction markets into publishing. Kalshi says three out of four of its users never trade.

What happened
- Polymarket's daily newsletter summarises the day's top stories and links each one out to the corresponding market, where a reader can take yes or no on whether the thing will happen.
- Polymarket has media partnerships with Dow Jones and Substack, while its larger rival Kalshi has deals with CNN, CNBC and Fox Corp.
- Those agreements do not facilitate trading; they are mainly data sharing, because news outlets want to know what people are putting their money on.
- The industry is fighting a series of legal battles over whether prediction markets are financial services or gambling platforms, a question that could reach the Supreme Court.

Why it matters
- contradiction Kalshi's spokesperson cites the non-trading majority as proof of informational value, but a trading share of one in four also means an editorial product aimed at the wider public is mostly reaching the three in four who don't trade.
- constraint Since the publisher deals move data and not orders, neither side can judge them on trading volume. The case for them rests on credibility, and nobody involved has quantified it.
- exposure A newsroom that puts Polymarket's odds on its own page is lending its name to the same social operation the New York Times found publishing false and misleading information.
A subscriber opens the email, reads a short summary of the day's news, and finds a link at the bottom to the market on it. WIRED, which gets the newsletter daily, rates it below Bloomberg's Money Stuff and Emily Sundberg's Feed Me as business analysis while calling it a recognisably commercial editorial product [3]. Subject lines have included "BREAKING: Trump Unveils Green Energy Beam" and "World War I, 2.0?" [1].
The pitch is large. Boosters describe prediction markets as "truth machines" that read public sentiment more accurately than polling or traditional reporting [9]. Shayne Coplan has called Polymarket's partnership with X "News 2.0" [14], and the careers page invites applicants to "Become the new front page of the internet" [16]. What has been built is a daily roundup plus data-sharing arrangements that, per a report WIRED cites, reach a quarter of the top 20 companies in the S&P 500's Communications Services sector, or five of them [5][20].
The one usage figure in the record belongs to the competitor. "And three out of four users don't trade, which suggests the informational use case is popular enough to be taken very seriously," Kalshi spokesperson Jack Such said [11]. He offered it as evidence that the markets have informational value [10]. Turned around, it puts Kalshi's trading share at one in four [19]. Such also said the company does not consider itself a media company: "We see ourselves as a financial exchange" [17]. Polymarket declined to comment [12].
WIRED calls the move into media a notably old-school hedge for two companies associated with risk [21], and the return it documents is credibility and a straightforward introduction to the wider public [8]. The account gives the media identity no role in the fight over whether these are financial services or gambling platforms [4]. The publisher agreements do not facilitate trading [7], and I would not expect a newsletter to settle what a market legally is. Financial firms have crossed into media before: Bloomberg began with market data and analytics before adding journalism, and Robinhood ran a media subsidiary called Sherwood before winding it down [18].
There is a cost to the credibility trade running the other way. A New York Times analysis earlier this year found Polymarket's newsy social accounts had published "false and misleading information" [13]. A newsroom that quotes the odds is quoting the same operation.
Anyone attaching content to a transactional product faces the same tests. Delete the link to the buy button and ask whether the content still has a reader; if it does not, it is sales collateral and should be budgeted as such. The other test is whether you can see a reader's first transaction at all, meaning reads to first trade within 30 days and usage depth after that, because a team that cannot measure the crossing will start quoting subscriber counts instead. Polymarket recruited for an editor in chief in 2024 to lead "content and data journalism", left the role open, and brought Nate Silver on as an adviser later that year [15].
What to watch
- Whether the classification fight reaches the Supreme Court, and whether either company's media positioning is argued in it.
- Whether Polymarket fills the editor in chief role it advertised in 2024, or keeps the newsletter as an unbylined roundup.
- Whether any publisher deal moves past data sharing into something that puts a trade button inside a news product.
