As of last month, I've completed my transition work with Hunterbrook Media, and I’m no longer the author of The Bear Cave.

Sam Koppelman and the Hunterbrook Media team are now writing the newsletter. I am rooting hard for them from the outside!

I’m now focusing my time on Sunday’s Idea Brunch newsletter, https://t.co/Nmn2sTdBkI, @BullpenDotNews, and prediction markets. Stay tuned for a lot more to come!

Some personal news: Hunterbrook Media has acquired The Bear Cave newsletter.

I started The Bear Cave to pursue independent investigative research and am excited to partner with a team that shares that mission. Hunterbrook will invest in bringing more original reporting to The Bear Cave’s readership and together we will bring the publication to new heights.

I’d like to thank so many people for helping make The Bear Cave a reality, starting with Professor John Shoven at Stanford, my first paid subscriber Jim Carruthers, early mentors like Marc Cohodes, Andrew Left, Doomberg, Petition, Bill Martin, and many others, including Substack founders Chris Best, Hamish McKenzie, and Jairaj Sethi for making it possible for anyone anywhere to build a following and income from writing online.

I owe endless gratitude to everyone who read and shared The Bear Cave, and especially those who supported The Bear Cave with paid subscriptions.

Above all, The Bear Cave would not exist if not for all the activist short sellers who speak truth to power:

@MediaKing Is a 30% commission too low? What’s industry standard?

[Edwin Dorsey @StockJabber]

@Activ8Insights Thank you!

[Activ8Insights @Activ8Insights]

Two names you already wrote up at The Bear Cave. $DKNG is down 52.0% since your September 2025 report and $SERV is down 68.1% since your December one.

Your Bear Cave record through the Hunterbrook sale, median target from the report-day open:

1 week: -3.5%
1 month: -5.0%
1 year: -20.7%
Since report: -24.0%

61% of those stocks are lower today, and almost a third have fallen 50% or more.

A great run. Excited to see what you do next @StockJabber
