A new analysis describes a third wave of American philanthropy fueled by AI equity stakes including the OpenAI Foundation's 26% holding valued at roughly $220 billion

Projected annual inflows of $35 billion could fund new universities.

One of the most important and under appreciated trends in the world right now.

1. 100s of billions of dollars will soon be available to solve big problems (making the world resilient to ASI, ending factory farming, etc). 2. The projects and organizations which will turn billions of 2027/28 dollars into impact need to be started NOW. 3. We need really talented people to start and run and work for these new projects. What @nanransohoff calls general managers, who feel personally resposible for solving one of the world’s important problems.

What is especially scarce are detailed visions about what making AI go well looks like. These will help inform what problems these new projects ought to work on.

One of the most important opportunities to do good in the near term! The scale of philanthropy will increase radically and the scale of some individual philanthropies - like the OpenAI Foundation - could allow them to operate unprecedented public benefit programs.

My own back-of-the-envelope math - if you trust in the bull case for AI - is that the OpenAI Foundation could wind up with trillions in valuation, spending tens to hundreds of billions per year. It might be more like a small country than a traditional philanthropy.

This is pretty mind-bending stuff. Private institutions now far outpace government in developing technology - the underlying basis of national power - and could soon meet government scale for pure public benefit distribution. This is not normal!

@ben_j_todd Helpful to distinguish "from Anthropic" and "from Anthropic employees", they're going to act very differently

Benjamin ToddBenjamin Todd@ben_j_todd

We're on track for ~$30bn/year of philanthropic funding from Anthropic and OpenAI foundations, enough to pay 150,000 salaries. Now, more than ever, our brightest young people should focus on solving the world's biggest problems, not PowerPoints at PwC.

This should enable to build big things again and faster: the largest particle collider, next-gen telescopes, space-based observatories, most powerful gravitational-wave detectors, supersonic jets, new measurement instruments, etc. CERN moves too slowly and America abandoned its own collider. super exciting times, especially doing it with AI!

The answer to this strikes me as obvious: “yes.”

Presumably OP is not saying, “this wealth should be spent on Porsches and Pateks instead of being spent on philanthropy!” Rather she seems to be hinting that the government should expropriate this wealth and spend it on <?????>. That’s what “in a democracy” is usually code for in contexts like this, by the way. It’s code for giving the government more money and power. Ironic, given the origins of American democracy.

Anyway, no, the government would have no idea what to spend this money on. Statistically speaking, this fortune, in the hands of the state, would most likely be squandered on old people’s retirement benefits, interest on debt, and weapons. “In a democracy.”

There are a ton of important things we will need to invest in to “make AI go well.” Long-range, bold, ambitious investments made by prudent and wise people. I do not know what species of delusion one must have to believe that the US government is well positioned to serve that role. America is fortunate to have a private sector and civil society that at least has a fighting chance of being up to the task.

There are many things I hope government will do during the AI transformation, but the expropriation gestured at below needs much more thought and justification than “in a democracy”-style sloganeering.

I like this! Noting, however, that depending on who says something like this and in which room, I may interpret it very differently.

Version 1: "Tax the rich, give to the poor" Version 2: "We need more AI4good nonprofits" Version 3: "We need to invest more in 'ai4good' for-profits"

I'm all for 1-2, just not 3. And based on how you say this would cost billions, I imagine we're on the same page.

Capitalism is literally a democratic allocation of capital.

The people have way more bits of control over allocation of capital towards solving problems.

In this case, all this philanthropy will be way more democratic than letting a few in power have the decision monopoly

yes, the bottleneck if you go the org building route is mostly just talent (there are not another 5 CG's worth of good capital allocators in philanthropy, nor is the equivalent number of founders available to run orgs that these allocators could grant to)

this is partly because the non-profit ecosystem is just much less compelling to top talent than the for-profit one.

therefore, you need to figure out how to use this capital some other way...

This is a good point well made. An earlier age of philanthropy created many public goods that people still enjoy today, and manifested a sense of reciprocity that helps sustain stable societies through rapid social and technological change. I don’t think many people still believe that reciprocity exists; the consequences of it fading out are easy to predict.

New blog post: The third wave of American philanthropy Hundreds of billions of dollars in new philanthropic capital will soon become liquid. The OpenAI Foundation holds 26% of OpenAI, worth about $220B at today’s valuation. Anthropic’s seven co-founders have pledged to give away 80% of their wealth and have instituted the most aggressive donor matching program for employees in tech history. How much does this all add up to? And how meaningful is that in the context of philanthropy today? I was doing some simple napkin math to wrap my head around the scale of what’s coming, and radicalized myself in the process. I had dramatically underappreciated the scale of the philanthropic capital that’s about to become available and the corresponding gap in talent and organizations that will be needed to make the most of it. This piece aims to directionally sketch the scale of what’s coming, the gap in operational capacity needed to absorb it, and what we can do to fill it. (Link to full post in reply)

I'd maybe deprioritize, checks notes, 5000 thinktanks or the nth nonprofit "alignment" "research" institute but, really, what do I know

A little nuts

Intense vertigo thinking about @nanransohoff's numbers. Based on current pledges/valuations, AI philanthropic giving would saturate an additional 300+ Arc Institutes, i.e. an extra 80K employees. Or 5,000 Institutes for Progress, demanding 200K employees! https://nanransohoff.substack.com/p/the-third-wave-of-american-philanthropy

@jessicadai_ Where are you quoting the “make sure AI goes well” from?

.@nanransohoff's framing is better than mine, but worth noting that again, if you wanted this take 6 months ago, subscribe to my blog.

This article has some good content, but it feels like it's asking 'other people' to do things.

I suggest spending 3 minutes thinking if you should run an org, or solve a problem and if not, then forget about it until next time you ponder.
