If stocks return ~7%/yr, $500m now grows faster early. Investing $100k/day only catches up after ~14,113 days ≈ 38.7 years.
NPV at 7% says the same thing: PV of $100k/day forever ≈ $539m, so it can beat $500m… eventually.
Also: if market returns are > ~7.6%/yr, the $500m upfront wins forever.
So unless you fancy waiting ~4 decades (or expect <7.6% returns), take the $500m.
