An extra $100M for animal welfare would be best spread across multiple years, given organizational constraints to scaling. I’d mostly have in mind outreach/​campaigns/​lobbying targeting corporations, certifiers, institutions and governments, and ballot initiatives for animal welfare policy change.
I mostly agree with Open Phil Should Allocate Most Neartermist Funding to Animal Welfare by Ariel Simnegar 🔸, as some others have already referenced. My animal moral weights are probably close to RP’s, and so higher than Open Phil’s.
Open Phil spent around $100M on animal welfare in each of 2021 and 2022.

There might be more direct ways to purchase animal welfare that would scale and still beat global health, but we could probably do much better with higher leverage policy interventions.
