Prof G Markets – "Why AI Needs Antitrust Intervention"

Featuring: Jonathan Kanter (Former Assistant Attorney General for Antitrust, DOJ)

Hosts: Scott Galloway (A), Ed Elson (E)
Date: October 17, 2025

Overview

This episode tackles the rising concern about how artificial intelligence (AI) is fostering dangerous market dynamics reminiscent of past monopolies and why antitrust intervention is urgently needed. Hosts Scott Galloway and Ed Elson speak with Jonathan Kanter, former head of the DOJ Antitrust Division, to explore the risks stemming from interlocking investments, circular deals, and market concentration among AI and tech giants.

Kanter explains that much like the oil and railroad trusts of a century ago, today’s tech companies wield enormous power by investing in and cross-owning each other’s ventures, threatening market resilience, innovation, and fair competition. The conversation also dives into parallels with the dot-com bubble, the pitfalls of current antitrust enforcement, and possible solutions — including earlier, targeted interventions and market modernization.

Key Discussion Points & Insights

Historical Lessons: AI Echoes the Era of Trusts

[09:33] D: Jonathan Kanter

• Antitrust laws were created to dismantle "trusts"—holding companies with tentacles across industries, stifling competition.
• Kanter compares today’s AI/tech boom to this: “A small number of companies led by modern day versions of J.P. Morgan, J.D. Rockefeller—putting their tentacles in all of these different businesses through these circular investments, creating the exact same circumstances that led to the creation of the antitrust laws in the first place.”

Today’s Power Players and the Illusion of Competition

[11:13] D: Jonathan Kanter

• Identifies tech giants—OpenAI, Google, Amazon, Microsoft, Nvidia, and Elon Musk—as the present-day “Rockefellers and Morgans.”
• These companies finance, invest in, and control putative "competitors" in AI. Anthropic, for example, lists Amazon and Google as major backers.

The Risks of Interdependence & Circular Investment

[13:14] D: Jonathan Kanter

• Resiliency risk: “If they're all interdependent and there is an issue with one of them…there can be this cascading effect…which could force us to enter into a collapse.”
• Stifled innovation & competition: When companies invest in each other instead of competing, there's little incentive to drive progress or lower prices.
• Capital recycling: Kanter warns that much investment stays in the tech sector between the dominant players (e.g., Google paying Apple ~$20B/year for search), rather than benefiting the broader economy.

Bubble Parallels: Dot-Com Lessons for AI

[19:37] D: Jonathan Kanter

• Valuation vs. Profits: “Everybody started imagining every Internet company or every good idea would…translate into a very profitable business…. And then there was the rationalization.”
• Today's AI euphoria echoes the dot-com era’s optimism—and its risks of sudden, massive corrections.

[21:20] A: Scott Galloway

• Notes that in a downturn, these concentrated tech bets could spark a global recession. Wonders if smaller, earlier interventions could lessen such systemic risk.

The Case for Early & Limited Antitrust Action

[22:53] D: Jonathan Kanter

• Advocates for “circuit breakers”:
  • Enforce bans on interlocking directorates (cross-board memberships that create conflicts).
  • Prevent concentrated cross-ownership and related party investments.
  • Increase IPOs and competition: “The path to prosperity is to build a company, then take it public…not just to be acquired.”

Drawing the Line: Competition vs. Collusion

[28:49] D: Jonathan Kanter

• Key warning signs:
  • Conflicts of interest (owning and operating the platform and the competition).
  • Circular investments and interlocking directorships.
  • “The simple rules of the road should be competitors should try to beat the crap out of each other. That’s their job.”

What Should Regulators Do?

[30:25] D: Jonathan Kanter

• “A little bit of intervention in some of these markets—a little bit can go a long way early on, but it often becomes a very messy exercise if…you’re trying to clean up a mess …with lots of dominant firms.”

Alternative Solutions: Modernizing Markets with Technology

[31:59] A: Scott Galloway

• Proposes tokenizing ownership of smaller private companies, made possible via AI compliance monitoring, allowing easier/safer public access and reducing barriers to IPOs.

[35:03] D: Jonathan Kanter

• Sees value both in technological modernization and in bringing more companies to public markets, democratizing access and better distributing gains.

Critical Ongoing Antitrust Cases

[36:59] E: Ed Elson / [37:22] D: Jonathan Kanter

• Google AdTech: Remedies are vital to ensure accountability—antitrust should go beyond "cost of doing business" fines.
• Ticketmaster/Live Nation: A rare, consumer-facing case highlighting the impact of vertical integration and monopoly (Ticketmaster controls a majority of ticket sales and venues).
• Apple, UnitedHealth & others: Enforcement should be meaningful and deterrent, not just symbolic.

Monopoly Impact on Everyday Prices

[39:55] A: Scott Galloway

• Live events: Ticket pricing has outpaced inflation, with monopoly players (Live Nation/Ticketmaster) capturing huge margins.
• [41:56] D: Jonathan Kanter
  • Other markets impacted include phone hardware (rising costs), healthcare (consolidation), and soon, energy.
  • “As data centers consume more energy, natural resources are becoming scarce…it is going to get significantly more expensive for families and businesses.”

The Popularity of Antitrust Cases and Public Confidence

[48:34] D: Jonathan Kanter

• Public support is crucial: “People want faith that their government is protecting them…. There’s a crisis of confidence in capitalism…in government.”
• Popular, tangible cases (like Ticketmaster) help rebuild trust and reaffirm the role of antitrust.

Capitalism vs. Socialism: What’s the Fix for Inequality?

[51:20] D: Jonathan Kanter

• Describes the rise of socialist-leaning proposals (like city-owned groceries) as a natural reaction to perceived market failures and inequality.
• “It’s a wonderful thing when it works…it’s worth fighting for. But we need to work to protect it.”
• Solution: “Capitalism, not socialism, but regulated capitalism.”
  • Focused on accountability, competition, opportunity, and a thriving middle class.

Notable Quotes & Memorable Moments

• On AI repeating history:

  “We have the exact same thing happening, which is a small number of companies…putting their tentacles in all of these different businesses through these circular investments, creating the exact same circumstances that led to the creation of the antitrust laws in the first place.”
  — Jonathan Kanter [09:33]

• On market resilience:

  “If they're all interdependent…there can be this cascading effect on all of the other dependent companies…could force us to enter into a collapse.”
  — Jonathan Kanter [13:14]

• On early intervention:

  “A little bit of intervention in some of these markets, not a lot—a little bit can go a long way early on.”
  — Jonathan Kanter [30:25]

• On the challenge of breaking up Big Tech:

  “They’re so intertwined now…breaking them up…would be like trying to separate Siamese septuplets. The surgery would be painful.”
  — Scott Galloway [55:09]

• On public trust in antitrust:

  “People want faith that their government is protecting them…. You give people confidence in government so that they know their taxpayers are being used to address the kinds of things that piss them off, like their concert tickets.”
  — Jonathan Kanter [48:34]

• On inequality and hope:

  “The purpose of an economy is to create a middle class. That’s the whole point…. When those billionaires garner so much political power…there’s no doubt about it, it’s not a growth agenda, it’s a transfer of wealth from lower middle-income homes to the top .01%.”
  — Scott Galloway [58:38]

Conclusion & Takeaways

• Structural issues in AI and tech markets threaten economic resilience and innovation through excessive concentration, cross-ownership, and circular investments.
• Historical antitrust lessons are relevant: Early, small interventions are more effective than drastic, late-stage “surgeries.”
• Public support is necessary for enforcement, and popular cases like Ticketmaster help rebuild trust.
• The answer isn’t socialism, but “refereed,” regulated capitalism—creating opportunity and protecting the middle class.
• Kanter’s most urgent advice: act now, not later, and use both technology and better regulation to open markets and distribute gains more widely.

For listeners seeking insight into the intersection of AI, markets, policy, and society—this episode offers both a warning and a pragmatic roadmap.
