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)

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.

Shouldn’t this mean > $100b in charitable giving for effective altruism adjacent projects from Anthropic founders & team members alone?

Within ~2 years, there might be >0.5 Manhattan Projects worth of philanthropic $$$ to spend on the biggest challenges, like cyber or biodefense.

@nanransohoff is right: the hard part is finding enough good organizations to spend the $.

You should build one!

Excellent and important post on an underrated topic: what will AI wealth do to philanthropy?

A little nuts

Andy MatuschakAndy Matuschak@andy_matuschak

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

.@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.
