AI Summary
5 min readIn early 2026, SpaceX went public in the largest IPO in history, debuting at a $1.75 trillion valuation. It was quickly worth more than Amazon, then briefly more than Microsoft. But veteran investor Barry Ritholtz, co-founder of Ritholtz Wealth Management, sees a problem: only 4% of SpaceX shares are publicly traded. That tiny float, he argues, is a case of "artificial scarcity" engineered by Elon Musk — and it is the most vivid signal yet that euphoria has taken over the markets. Ritholtz sat down with Scott Galloway and Ed Elson of Prof G Markets to explain why this cycle is different from the dot-com bubble, where the real risk lies, and why most investors should simply sit still.
The SpaceX IPO: Financial Engineering, Not Fundamentals
Ritholtz is blunt about the SpaceX IPO: "This smacks of engineering, which tends not to be fantastic for investors." Only 4% of shares are publicly traded — a float so small it is "walking-around pocket change." NASDAQ changed its own rules to allow SpaceX in with that tiny float, a move Ritholtz calls a transparent bid for "sexiness" by a minor index.

What you'll learn
- 1 (06:05) **Guest Introduction: Barry Ritholtz** - Co-founder, chairman, and CIO of Ritholtz Wealth Management, known as the "blog father" for his finance blog The Big Picture, joins to discuss market euphoria.
- 2 (07:18) **SpaceX IPO: "Brilliant Financial Engineering"** - Ritholtz argues the $2.5T+ valuation is driven by artificial scarcity (4% float) and index inclusion rule changes, warning it's engineered for hype, not value.
- 3 (14:47) **Index Inclusion: Demand vs. Value** - Hosts and Ritholtz debate whether forced buying from index funds (NASDAQ 100) can sustain the overvalued price, with Ritholtz pointing to the Tesla 2020 precedent as a cautionary tale.
- 4 (18:53) **Retail Frenzy vs. Institutional Skepticism** - Ritholtz says he has never had more people ask about an IPO, but he cautions that IPOs generally underperform the market a year later, and the "Elon brand" is slightly tarnished.
- 5 (23:40) **Why This Is Not the Dot-Com Bubble** - Ritholtz presents a three-part thesis: 1) All-time highs are bullish (582 from 1982-2000), 2) Earnings are at record levels and growing, and 3) AI is more comparable to the Industrial Revolution than the internet, with real products and enterprise revenue.
- 6 (31:26) **Challenging the "Real Profits" & "Circular Revenue" Claims** - Hosts push back on AI profitability and circular deal-making (e.g., Google buying chips from SpaceX), comparing it to dot-com metrics. Ritholtz counters that capital from bond markets is "real money," unlike the 1990s Cisco financing model.
- 7 (38:26) **The "Relentless Bid" and IPO Capital Absorption** - Ritholtz argues that the 401(k) "relentless bid" means new IPOs like SpaceX won't significantly drain capital from giants like Apple, as most new money flows into existing holdings.
