If AI drives a 1990s-style productivity boom (2.5-3.5% annual productivity growth), US debt-to-GDP could bend down toward 80% instead of rising to 140%.
Philippe Laffont lays out Coatue's analysis that sustained AI-driven productivity gains comparable to the 1990s internet/PC era could meaningfully lower, not just stabilize, the US debt-to-GDP ratio. ✦ AI generated

“how important is believing this to be true in our overall kind of public uh investing today?”
we said what would it take for actually debt to GDP to stay at 100 or maybe even bend the curve and go down to 80. And what's really surprising I think if you just show maybe the next slide or or so yeah uh I think if we move forward yeah just a little bit you'll see that if productivity for the next decade or so was about 2 and a half to three and a half% per year we could achieve substantial reductions in this key ratio of debt to GDP.

32:20140. And we said what would it take for actually debt to GDP to stay at 100 or maybe even bend the curve and go down to 80. And what's really surprising I think if you just show maybe the next slide or or so yeah uh I think if we move forward yeah just a little bit you'll see that if productivity for the next decade or so was about 2
32:42and a half to three and a half% per year we could achieve substantial reductions in this key ratio of debt to GDP and I'm not saying we're there but I'm saying that at least we've been able to bookend what would productivity need to be to achieve an 80 100% instead of 140 debt to GDP. This is slide 51 just for the people uh following along which is you
33:08know again an incredibly important point. We know there are people buying bonds every day at 4.5%. So the question is why are they doing that? And one of the answers may be exactly what you're saying. What if they're right? Exactly. What if they're right and we're wrong? And in fact uh one funny part is in 1993 debt to GDP was supposed to go from 40 to uh or 60 to 80 by expert and it in
33:33fact went from 60 to 40. Yes. So experts can be wrong by a lot. Right. And so I'm not a good enough macro guy and if tech guys pretend to be good macro guides, you know, it's the beginning of the end. But at least we have a little bit of analytical thinking around what it would take. and Bill and Thomas, you guys are much better placed than me in terms of
33:57your discussions with all the privates, which I think we're leading to now, and all these amazing new products. And you're telling me that that's not going to create like massive productivity. I really think it is. And and and drawing from that, you would end up with with GDP growth way more in like the 5% plus, maybe even six, which by the way, that was the case for many of the years in
34:19the 90s. then sort of product uh you know uh and by the way the six would represent four and about real terms whereas in the past you know most recently we'd more be at like you know two or three which is more like the one in terms of real terms so you know just to wrap up your flight path for the public markets I think it's fair to
- ·Coatue modeled what it'd take to stop debt-to-GDP rise
- ·Goal: hold ratio near 100%, or bend down to 80%
- ·Key lever: sustained productivity growth, like 1990s tech boom
- ·2.5–3.5% annual productivity growth for ~a decade
- ·At that pace, debt-to-GDP could fall substantially
- ·Without it, trajectory points toward 140% debt-to-GDP
