Episode 812 of DH Unplugged, titled "Rollercoaster Ride," hosted by Andrew Horowitz and John C. Dvorak, arrives August 4, 2026 with markets whipsawing on Big Tech earnings, a collapsing Korean stock market, and a SpaceX unwind that has become the talk of Wall Street. Horowitz, recovering from meniscus surgery two weeks earlier, walks listeners through Dow swings of 1,000 points up and 700 points down, oil reacting to a war that flipped off again, and a tape where names like Palantir jumped 26% while AMD dropped 8% after hours.

The hosts move quickly through a packed docket:

• Microsoft, Apple and Amazon earnings, with Amazon crossing the $3 trillion mark and Apple falling 7% on memory chip cost warnings.
• The KOSPI meltdown, single stock leveraged ETFs, and 350,000 blown out Korean retail accounts.
• SpaceX's post-IPO slide from lockup expirations, a Starlink subscriber miss, and $40 billion in fresh debt priced toward junk.
• AI "hackathon" narratives from OpenAI and Anthropic, plus Google's new selfie-based authentication push.
• Reddit's 20% plunge on weak AI licensing demand and a Meta miss tied to its Scale AI acquisition.

Dvorak remains skeptical of the AI safety marketing cycle, framing the escalating "capture the flag" breakout stories as a regulatory moat play. "Their large marketing campaign goes around the idea that their AI is going to kill us all. So buy now, don't miss out on having the evil machine work for you," he tells Horowitz, noting OpenAI has been running the same playbook since GPT-2. Horowitz counters that either interpretation, deliberate manipulation or genuine incompetence, is unsettling for investors trying to price the sector.

On SpaceX, Horowitz calls the move a rug pull, pointing to insider selling, expired lockups, and the absence of syndicate support from Goldman Sachs, Morgan Stanley and Merrill Lynch around the $135 level before shares hit $108. The hosts also dig into housing, where Miami now shows roughly 140 sellers for every 100 buyers, and compare stuck listing prices to unsold Beanie Babies on eBay. Other threads include TSMC's additional $100 billion Arizona investment, Delta's confidence in sticky higher fares, a 1.6 million dozen egg salmonella recall, cheap lamb and shrimp at the grocery store, PCE inflation stuck at 3.3% core, and a fresh 50% Trump tariff on Canadian goods.
