Who writes Deep Markets?

Deep Markets is written by Cavin and published on Substack. The publication has been running for about four years and has hundreds of subscribers. Its stated focus is "AI x Business," so if you are deciding whether to subscribe, the practical question is whether Cavin's writing on the intersection of AI and business matches what you want to read.

What the publication page tells you

The available information about Deep Markets is limited to its Substack landing page. The page identifies the author as Cavin, gives the publication name, and describes the subject as "AI x Business." It also shows that the publication launched four years ago and has hundreds of subscribers.

The page does not list individual article titles, a publishing schedule, or a detailed author biography. It also does not state pricing for a paid subscription. The only subscription signal on the page is a "Subscribe" prompt, which is standard for Substack publications and does not by itself confirm whether paid tiers exist.

How to check the author and content before subscribing

If knowing the writer matters to you, use the publication page itself rather than secondhand descriptions.

1. Open deepmarkets.substack.com in a browser with JavaScript enabled. The page notes that it requires JavaScript to run correctly, so a blocked script may leave it blank.
2. Look at the publication header and description to confirm the author name and topic.
3. Scroll the archive or post list, if one is displayed, to see actual article titles and dates. This is the most direct way to judge whether the "AI x Business" framing matches your interests.
4. If you want email delivery, enter your email in the subscribe field. Substack's terms and privacy notice are referenced at the point of subscription, so review those if data handling matters to you.

A reasonable expectation from the page alone: you will get a Substack newsletter by Cavin about AI and business, with a multi-year archive and a subscriber base in the hundreds. You should not assume a specific cadence, a free-versus-paid split, or a particular depth of coverage, because the page does not state them.

Common sticking points

• Blank page or missing content. The site explicitly requires JavaScript. If the page will not load, check script blocking or try another browser before concluding the publication is inactive.
• Confusing "subscribe" with "free." Substack uses one subscribe flow for both free and paid options on many publications. The page here does not show pricing, so confirm any paid terms during the signup flow rather than assuming access is free.
• Judging quality from the description alone. "AI x Business" is broad. Reading two or three recent posts is a better test of fit than the tagline.

Bottom line

Deep Markets is Cavin's Substack publication on AI and business, active for roughly four years with hundreds of subscribers. To decide whether to follow it, open the site with JavaScript enabled, skim the archive for topic fit, and check the subscription terms shown at signup, since the landing page does not specify pricing or posting frequency.
