Episode summary
Wall Street Week | AI Debt, Austin Housing Test, Student Loan Reckoning, Canada Weighs US Tariffs
Wall Street Week
· · 57 min · Guests: Steven Rattner
Summary
Artificial intelligence remains the market’s central story, but Steven Rattner argues the next phase is less about whether AI matters than which companies capture the value. He says investors have probably been too exuberant about borrowing tied to the buildout, and that higher rates and rising debt costs could eventually pressure valuations, especially for long-dated growth bets and debt-heavy private equity deals.
The episode also looks at housing affordability through Austin, Texas, where local zoning and permitting changes helped unleash a surge of new supply. The result, according to the host and local market participants, has been sharply lower rents and a test case for whether building more can cool prices without freezing development altogether.
A second policy debate centers on graduate student lending. With Grad PLUS ending and annual caps now in place, the program’s critics say unlimited federal loans inflated tuition and debt, while university leaders warn the new limits will shrink enrollment and reduce the supply of teachers, counselors and social workers. The show closes on trade, with Chrystia Freeland warning that fresh Canadian tariffs could escalate a contentious USMCA fight, even as Steven Rattner says tariffs have done little to revive manufacturing or fix the U.S. deficit.
Key takeaways
- Steven Rattner says AI will matter enormously, but the market still does not know who the winners and losers will be.
- Rattner says higher interest rates can hurt AI and other long-duration growth stocks by raising discount rates.
- Austin’s supply-side housing reforms helped drive down inflation-adjusted rents 19% from the 2021 average to 2025, according to the episode.
- The end of Grad PLUS creates a funding gap for many graduate students and could reduce enrollment in teacher, counseling and social-work programs, the guest and university leaders warn.
- Rattner says tariffs have had almost no meaningful effect on shrinking the U.S. deficit and have not reversed the manufacturing downtrend.
Notable quotes
“The movie's going to end with a lot of artificial intelligence. In my opinion, it's going to be a huge contributor to society, to the economy, to our lives”
“I think the market got caught up in a little bit of irrational exuberance, to borrow a phrase, when... when Google and others financed all that debt”
“The market is much more focused on other things than tariffs at the moment”
“-The government can do what they want to do, but if you add supply, rents will drop”
“Education is infrastructure as much as roads and highways are”
How the episode opens
David Westin: This is "Wall Street Week. I'm David Westin bringing you stories of capitalism. Affordable housing is a problem pretty much everywhere across the United States.
We go to Austin, Texas, to look at one city that's actually doing something about it. Plus, giving grad students a way to finance their education seemed like a good idea at the time. Now, cutting back on the support is creating problems for students and universities alike.
And tariffs are back with a vengeance, as President Trump threatens 50% levies on a range of Canadian imports, with more to come. What will they mean for trade and for the U.S. economy?
But we start once again with artificial intelligence. In a week, when the Chinese came forward with yet another model that they claim is cheaper than the U.S. alternatives and can do just about as well.
Steven Rattner is chairman and CEO of Willett Advisors, which invests the personal and philanthropic assets of our founder and majority shareholder, Michael Bloomberg. So, Steven, artificial intelligence has been all the talk of the markets for some time now, both the investment in it and the promise of it. There are some questions being raised right now.
What do you think of those questions? Are they serious questions? -Oh, they're definitely serious questions, David.
Let me step back just for a second and say that every technological innovation that I've seen happen has always occurred with sort of a swirling of the cosmos effect, where the stars are forming and you don't quite know how it's all going to shake out for a while. And that was certainly true, for example, when we had computers came in. There were many different computer manufacturers, many different systems and so forth, and all the way through the internet.
