The Irrationality of Markets (on Steroids)
With almost no time to write today, I did want to comment briefly (albeit mostly via other writers) on the current madness in US financial markets. In case anyone has missed it, several huge companies are “going public” this summer, which will make the superrich superricher. The first such market splash has been playing out for the last few days.
None of it makes sense, but that should surprise no one. Here are a few examples of sane analyses of the financial markets' recent insanity.
(1) Hype and Glory: The SpaceX frenzy continues, Paul Krugman, June 17, 2026, an excellent analysis that demonstrates that SpaceX's financial "fundamentals" are completely insane. Krugman includes this gem:
Robin Wigglesworth, editor of the Financial Times blog Alphaville, memorably described Elon Musk’s company as a
"very successful but fairly small satellite launch company, bolted onto a stagnant money-losing social media company [X, formerly Twitter] and a money-incinerating AI company [xAI, operator of the widely despised model Grok], and then sprinkled with a lot of hype about humankind going interplanetary."
Krugman also links to this on CNET:
(2) SpaceX IPO Live: Elon Musk Is a Trillionaire, and the Rest of Us Aren't, Jon Reed, Laura Michelle Davis, Joe Supan, and Katelyn Chedraoui, June 12, 2026
That article includes plenty of fascinating (and depressing) information, including this eye-opener:
It's worth a reminder that SpaceX, which has over 22,000 full-time employees worldwide, is known for its treacherous workplace conditions -- long hours, crunch conditions and lax safety protocols -- and its stance against unionization. A 2023 Reuters investigation documented at least 600 previously unreported injuries at SpaceX facilities, which represent only a portion of the total case count -- this includes crushed limbs, amputations, electrocutions, head and eye wounds and one death.
And we must not forget that it is not only tech fads that can drive financial traders to make incomprehensible decisions:
(3) How Naive Are Oil Traders? Michael C. Dorf, June 04, 2026
Professor Dorf's piece includes this:
What we are observing is a kind of naïveté among enough oil traders to affect market prices. And to be clear, that must mean a lot of such traders, because a small number of traders who naively believe what Trump claims about an imminent deal cannot move markets. More savvy investors would see these MAGA-traders selling oil futures on news of an imminent deal and take advantage of these fools by buying low, thereby driving the price back up. All of that should happen so quickly as not to register in daily closing prices.
Finally, I also recently weighed in on how these things matter, but also noted how impossible they are to understand:
(4) It Doesn't Matter That Nobody Understands Stock Market Swings (Even Though Stock Markets Matter), Neil H. Buchanan, April 16, 2026.
This passage seems especially relevant today:
[I]t is always worth going back to one of my favorite quotes from my favorite economist. John Maynard Keynes (the bête noire of the right for most of the last one hundred years) is perhaps most famous for saying "In the long run, we're all dead," or perhaps "When the facts change, I change my mind. What do you do, sir?" (The latter quote is possibly mis-attributed to Keynes). He also, however, once wrote that the movements of financial markets and other transactions "can only be taken as a result of animal spirits ... and not as the outcome of a weighted average of quantitative benefits multiplied by quantitative probabilities."
Keynes was an especially reliable observer in that regard, because he was an active speculator who had real success (along with some disastrous failures) managing the endowment of King's College, Cambridge University. If he says that humans make decisions based on instinct and uninformed overconfidence, I tend to believe him.
And this week's frenzy proves Keynes right yet again.
