The IPO only sold a few percentage of their shares. Even if we assume they sold all of them at opening price, by close the company and employees still hold like 80% of their shares that are worth triple what Adobe would have paid.

We're talking about Adobe FFS, they have some crazy prices and shitty dark patterns around trials & cancellations.
