Frequently asked questions

What is the best prediction markets newsletter?
Event Horizon is our top pick. Dustin Gouker publishes most weekdays on Kalshi, Polymarket, sports event contracts, and the regulatory and court fights around them, drawing on a decade covering the US gambling industry. It is free, and there is a companion podcast for the longer interviews.
What is the best free daily prediction markets newsletter?
The PM Pulse, written by Sam Schwartz, lands every weekday at 6:00 AM ET and is designed to be read in five minutes. It pairs the day's industry news with a weekly trading-volume scoreboard and periodic founder interviews. It launched in July 2026 and is free.
What is the difference between a prediction markets newsletter and a sports betting newsletter?
Prediction markets newsletters cover event contracts traded on exchanges such as Kalshi and Polymarket, which sit under federal commodities regulation rather than state gaming law. Sports betting newsletters cover sportsbooks, odds, and the leagues. The two now overlap heavily, because sports event contracts have pulled the exchanges into the same arguments, which is why this guide carries both.
Which newsletters cover Kalshi and Polymarket specifically?
Event Horizon and The PM Pulse both cover the exchanges as an industry beat, day by day. The Prob tracks the largest price moves and most-traded contracts across both platforms each morning. The Oracle by Polymarket is written by Polymarket itself, so read it as a first-party publication.
Do any of these newsletters sell betting picks?
None of the newsletters in this guide sells betting picks. That is deliberate: tout services and the affiliate-funded odds sites that publish expert selections sit in the sports betting and fantasy guide instead, because this category is about prediction markets, the industry and the regulation around them. Hark does not evaluate anyone pick record, and nothing here is betting advice.
Which newsletters cover the legal and regulatory fight over event contracts?
Legal Sports Report Newsletter is the most consistent source on state regulators, legislation, and litigation in US betting and prediction markets. The Closing Line and Event Horizon, both from Dustin Gouker, cover the same ground with more analysis and opinion. The legal position is changing month to month, so check the date on anything you read.
Are any of these newsletters published by the platforms themselves?
Yes, two. The Oracle by Polymarket is Polymarket's own Substack, and Above The Fold is published by Manifold Markets, a play-money forecasting platform. Both are worth reading for what the platforms are building, but they are company publications, not independent coverage, and we label them that way.
Is there a newsletter that explains how prediction markets actually work?
Prediction Markets Newsletter, by Rutgers statistics professor Harry Crane, is the teaching read in this category: posts on odds, parimutuel pools, contract design, and what makes an event well defined enough to trade. Be aware that it publishes irregularly and went quiet after June 2026, so treat it as an archive to work through rather than a daily habit.
What is the best newsletter for the business of sports betting?
SBJ Betting, from Sports Business Journal, covers operators, league and media partnerships, state revenue, and gambling regulation for an industry audience. It publishes weekly. If you want the same beat daily and with more opinion, The Closing Line is the complement.
What is the most efficient way to keep up with betting & prediction markets news?
Reading every betting & prediction markets newsletter takes real time, and the biggest stories repeat across them. The efficient approach is a small set of complementary sources, summarized. That is what Hark News does: choose your newsletters inside Hark (the bundles above are one-tap starting points), and each morning it distills what they published into a concise audio newscast you can play while you get ready, commute, or walk. You get the substance of the whole list without the inbox pile, free to try at hark.news.
How does Hark rank these betting & prediction markets newsletters?
Hark’s editors hand-rank every newsletter in this guide on breadth of coverage, publishing frequency, publisher authority, original reporting, free availability, and track record; audience reach informs the research, but raw subscriber counts never decide the ranking. The picks and bundles above are curated the same way, with the reader in mind. Placement cannot be bought: publishers cannot pay to appear or to rank higher. The list is re-verified monthly and updated as the category changes.
How often is this list updated?
Hark re-checks this catalog every month: editors verify each newsletter is still publishing, confirm sign-up links work, and add or retire titles as the category changes. The “Last updated” date at the bottom of the page reflects the most recent verification pass.
