· · Hosts: Carol Massar, Tim Stenovec · Guests: Erik Larson, Ed Zitron, Wendy Stewart, Carina Kern
Summary
The episode opens with the guilty verdict for short seller Andrew Left, whom the host says was convicted of using “disingenuous social media post to manipulate stocks.” A guest explains that prosecutors argued Left traded opposite to his public commentary across more than a dozen companies, including Twitter, Facebook and Nvidia, and says the case could chill short selling because it leaves the line unclear between legitimate bearish research and manipulation.
The conversation then turns to artificial intelligence skepticism, where a guest argues that the market is confusing a semiconductor rally with a profitable AI business. He says major model makers lack a clear path to profitability, that customers may be unable to measure AI’s true cost, and that public markets could be shocked when these companies eventually file.
Later segments shift to Bank of America’s view of the middle market, where a guest says clients are using M&A to grow, manage supply chains and expand globally, and that AI adoption is focused on customer experience, frontline productivity, process improvement and efficiency. The final interview explores a longevity biotech developing a drug aimed at necrosis, with the founders saying they hope to move into clinical trials for kidney disease as a “gateway” indication.
Key takeaways
- A guest says the Andrew Left verdict may chill short sellers because it could create new enforcement lines without clear regulations.
- The guest on AI argues that OpenAI, Anthropic and similar firms are being valued ahead of any proven return on investment.
- Wendy Stewart says middle-market clients are using M&A, supply-chain changes and AI to drive growth and efficiency.
- Dr. Karina Kern says Longevity is targeting necrosis as a root mechanism of aging and plans a kidney-disease clinical trial first.

This is one of the most read stories on the Bloomberg terminal in the past day. It crossed late yesterday. We got more details on it overnight.
It's about the famed short seller Andrew Left. He faces the possibility of decades behind bars. He was found guilty of using disingenuous social media post to manipulate stocks.
In a landmark case, it threatens to chill a broader trading strategy that's just loathed by corporate executives. We've got Eric Larson with us. He's US legal reporter for Bloomberg News.
He joins us from Los Angeles. Eric, just just remind us who Andrew Left is, what Citron Research made a name doing.
Sure. As you said, he uh he he grew a big following on Twitter actually is where he got so many followers tracking everything he was saying about companies that he was researching through his Citron research. Um he made some good calls back in the day on a few companies that gained him extra followers and really this this group that was following him is who he tried to manipulate here according to the justice department.
So you mentioned this trading strategies that's loathed by companies. It has to do with building a short position on a company and then trashing it in a research report or tweets in Mr. Left's case.
And so the government said that Mr. Left went a little beyond just doing that. So, it's a it's a really, like you said, it's a landmark case and the short selling industry is really wondering what it means.
