Date: March 24, 2026 | Host: Ed Elson | Guests: Justin Wolfers (University of Michigan), Alex Heath (Sources newsletter & Access podcast)
OVERVIEW
This episode dives into two of the week's biggest stories driving headlines and markets:
- The extraordinary $1+ trillion swing in capital markets following reports of supposed US-Iran “talks”—which Iran then denied.
- OpenAI’s major business pivot as competition in AI heats up against Anthropic, and the company’s controversial new investment strategy.
The show features wide-ranging analysis, skepticism, and urgent lessons for investors about how market narratives are shaped—and misleading.
Key Segment 1: Iran “Talks,” Market Volatility & Presidential Credibility
Guests: Justin Wolfers (Economics Professor, UMichigan)
Background
- [02:18] US markets rallied after President Trump announced "very strong talks" with Iran to de-escalate conflict. Oil prices and Treasury yields fell.
- [02:56] Iran's Parliament swiftly denied that any talks had taken place.
Main Insights & Analysis
- Markets now move trillions of dollars “on fog and ambiguity,” unable to trust official statements.
- Justin Wolfers [03:58]: “It's the most extraordinary thing that the most critical issue facing American financial markets is whether to believe the American president or the Iranian leaders… That right there tells you that markets believed that our president is slightly more credible than the Iranian leadership, but not substantially so.”
- Enormous Wealth at Stake Over Words
- Wolfers [04:40]: “1% on the S&P 500 is $600 billion. Maybe it rose about one and a half percent... about a trillion dollars. That says whether the President was telling the truth or not makes a difference in the wealth of the average American household of plus or minus $10,000.”
- Deep Uncertainty & Feedback Loops
- Markets aren’t “crazy”—they’re responding rationally to massive unknowns.
- Wolfers [07:20]: “It's not a statement about financial markets necessarily being temperamental. It's more a statement about the President's inability to convince anyone that what he's saying he means… One profound sense is I don't think we've ever been in a situation like this where the word of the present about what his intentions are is so uninformative about the future.”
- In comparison, past Presidents’ statements were far more reliable signals to markets (e.g. G.W. Bush).
- “Taco” Theory—Presidential Backtracking’s Market Effect
- Ed Elson [08:29]: “Are we in the same position again, where we're basically just hanging onto his every word, making decisions…which often just don't pan out to be even true?”
- Wolfers [09:23]: “If your simple model was the President will do what he wants until markets don't like it, then he'll undo it… Maybe, you know, all of this comes back to…how do you rewrite the rules of the game when you have an unpredictable president?”
Key Quotes
- “We are sailing through fog at midnight with a blindfold on while listening to the sweet, sweet tunes of our President telling us what may or may not be happening.” — Justin Wolfers [05:12]
- “Yes, he tacos sometimes, except when he doesn't…it's not even clear that the President has. So, mate, if I look a little bit lost, it's because this is very confusing.” — Justin Wolfers [10:20]
Real-World Implications
- With the Iran Strait of Hormuz conflict unresolved, the stakes are massive:
- Oil at $150–$200/barrel could spark global inflation
- Future market swings are inevitable on ambiguous news
Takeaway for Investors
- “If you want to stop losing money, it's quite simple. Stop listening to the President and for one simple reason. Meaning cannot be made out of that which has no meaning at all.” — Ed Elson [27:23]
Key Segment 2: OpenAI’s Strategic Shift
Guest: Alex Heath (AI Reporter)
Background
- OpenAI is moving away from “side quests” to focus on enterprise products.
- An internal memo signals a push for a “super app” (combining ChatGPT, Codex, Atlas browser), doubling headcount, and competing with Anthropic’s Claude.
Insights & Industry Context
- Consumer vs. Enterprise AI
- OpenAI won in consumer markets (900M+ users), but most users cost more than they generate.
“OpenAI went square for consumer…They have 900 million users…Meanwhile, what Anthropic did is…focused almost entirely on enterprise.” — Alex Heath [17:45]
- Anthropic focuses on profitable enterprise deployments; OpenAI is now following, especially in coding.
- “Where is the money in AI? It’s in enterprise applications…That’s the way to do it.” — Heath [18:35]
- OpenAI won in consumer markets (900M+ users), but most users cost more than they generate.
- Revenue Challenges & Opportunities
- Consumer AI is “hard to monetize”—OpenAI now hiring Meta ad executives and exploring advertising.
“The super app idea makes a ton of sense and as does growing the enterprise push…This is just the beginning.” — Heath [19:43]
- The real competitive edge may be “figuring out the ads piece,” which would bring Google/Facebook-like margins (Heath, [21:10]).
- Consumer AI is “hard to monetize”—OpenAI now hiring Meta ad executives and exploring advertising.
Noteworthy Moments & Quotes
-
On OpenAI’s catch-up in enterprise:
“I think they view not focusing on coding and coding model progress earlier as a mistake, as a huge strategic mistake that they're now catching up on.” — Heath [21:10]
-
On the prospect of advertising in AI products:
“If you bought the theory from Sam Altman that superintelligence ... is just around the corner ... would you be doing a concerted ads push?... There's no, I think ChatGPT is going to be around for a long time... it's like the Kleenex of AI for a lot of people.” — Heath [23:34]
-
On OpenAI’s 17.5% guaranteed private equity returns:
"That's like a ridiculous return…someone has been picking up the bill constantly…OpenAI right now is contingent on Sam's ability to convince another large pool of capital that he has somehow not already tapped to invest more money until they become profitable." — Heath [25:53]
Market & Business Implications
- There’s investor skepticism about the sustainability of current AI development and compensation models.
- OpenAI’s guarantee of such high returns signals either immense confidence—or risk.
Memorable Moments & Quotes
- “We are sailing through fog at midnight with a blindfold on while listening to the sweet, sweet tunes of our President telling us what may or may not be happening.” — Justin Wolfers [05:12]
- “If you want to stop losing money, it's quite simple. Stop listening to the President and for one simple reason. Meaning cannot be made out of that which has no meaning at all.” — Ed Elson [27:23]
- On OpenAI’s strategic rethink: “Turns out most of their users cost them money to serve...Now they’re trying to build out an ads business—just hired a top exec from Meta.” — Alex Heath [21:10–23:00]
- On the market swings: “This time we're betting not on trade policy, but on all out war.” — Ed Elson [27:23]

Takeaways & Lessons

- Investors (and the public) should recognize the historic level of uncertainty—and avoid overreacting to the “fog” of official statements.
- In AI, leading players (OpenAI, Anthropic) are still racing to find sustainable business models, with strategic pivots and high-risk investments as common features.
This episode offered not just coverage of headline news, but deep skepticism, practical investor wisdom, and a front-row seat to how modern markets are shaped by both real and illusory narratives.
