I think a better framing might be projects that Open Phil and other funders would be inclined to fund at ~$X (for some large X, not necessarily 100M), and have cost-effectiveness similar to their current last dollar in the relevant causes or better.
I think I disagree and would prefer Linch’s original idea; there may be things that are much more cost-effective than OPP’s current last dollar (to the point that they’d provide >>$100M of value for <<$100M to OPP), but which can’t absorb $X (or which OPP wouldn’t pay $X for, due to other reasons).

I think you can adjust my proposal for this:
Cost-effectiveness similar to or better than Open Phil’s last dollar.
Impact similar or better than the last $100 million Open Phil spends.
Maybe having a single number is preferable. Ben Todd recommended going for the project with the highest potential impact (with a budget constraint).
