Why do you think Stripe will get acquired (and soon)?

I personally think it'll stay a standalone company because its founders already have plenty of money (from Auctomatic and presumably from taking money off the table during Stripe's funding rounds) and seem intensely motivated to change the world by having a pivotal role in increasing the GDP of the internet (as stated in the article).

That, coupled with its (both the company and its founders) integrity, culture, and care & empathy for people (employees, investors, customers, partners, underserved and underestimated people and markets, and really almost anyone) seems to indicate to me that its core values and objectives will be best served and achieved as an independent entity.
