Prices during normal trading hours would count.
A single fat finger trade might be discounted but if it remains as being shown as a 52 week high on google after a week then it will count.
Update 2025-10-29 (PST) (AI summary of creator comment): Creator will use Google's displayed market cap as the source for determining when a company reaches $5T. Creator will wait for Google to update/stabilize its displayed value before resolving.
@deagol Thanks, I had looked there and seen that. Google was showing me 4.90T 5 mins ago but now shows 4.89T. Do we know why there is a difference? I would prefer to be sure before resolving.

We have a $5T company!
@Luxeed Thanks. For some strange? reason Google is showing me 4.90T but I expect it will sort itself out and I will be able to resolve soon.
