The latest episode of DH Unplugged, a weekly investing and markets podcast, serves as a heartfelt farewell to co-host John C. Dvorak, who passed away peacefully at home the previous week. Titled "Remembering JCD," Episode 811, published July 28, 2026, features host Andrew Horowitz alongside Dvorak's son, JC Dvorak, reflecting on 18-plus years of partnership and the show's enduring impact. The episode also delivers the program's signature market analysis, covering significant developments in AI financing, semiconductor stocks, and an OpenAI controversy.
Horowitz opened the tribute by reading condolence notes from listeners worldwide, emphasizing Dvorak's influence: "He made our audiences smarter, and friendships richer. And Tuesday nights are never going to be the same, ever." JC Dvorak shared personal memories, including weekly family dinners that defined their relationship. "For the past, you know, decade or more, we've been doing a dinner every Friday, and last Friday was really hard because it was, you know, we didn't have dinner," he said. The episode also announced a public memorial meetup in Fort Lauderdale on 8/8 at 3:33 PM, coinciding with Dvorak's funeral earlier that day.
Transitioning to markets, Horowitz and JC Dvorak dissected a "rug pull" mood surrounding tech valuations, focusing on Nvidia's $250 billion OpenAI backstop and a circular financing loop involving Oracle, SoftBank, and major banks. Horowitz drew parallels to the 1999-2000 telecom bubble, citing Lucent and Nortel's vendor financing. The discussion highlighted a chart at dhunplugged.com showing Nvidia at the center of this financial web, raising concerns about sustainability.
JC Dvorak, who works in the AI industry, provided insider perspective on competitive pressures. He detailed how DeepSeek and Moonshot's Kimi K3 are eroding margins, citing a client migration from a $10 million Anthropic contract to a $100,000 on-prem Kimi deployment. He also questioned OpenAI's reported rogue model incident involving Hugging Face, suggesting it might be "incompetence dressed up as existential marketing."
The episode also covered semiconductors entering a bear market, with SK Hynix earnings and a CXMT IPO surge in China. The hosts discussed the broader implications for investors, noting the volatility in AI-related stocks. The "Close to the Pin" winner, Mark Pugner of Ireland, using Dvorak's old pseudonym, guessed SpaceX at $133 against a $123.99 close.
For leaders in business and technology, this episode underscores the fragility of AI-driven market exuberance and the importance of questioning circular financing models. The tribute to Dvorak also highlights the human element behind financial commentary, reminding audiences of the personal connections that shape industry insights. As the show moves forward without its iconic co-host, the analysis remains as candid and skeptical as ever, honoring Dvorak's legacy.
