In the example I provided, it would be those that sold their commercial real estate before the pandemic. Other winners would be pharmaceutical companies, residential builders, internet retailers, people that prefer working from home, and families that enjoy each others company to name a few.
Obama set up a pandemic preparedness office which coordinated with China. can't call it a huge win, since the other guy dismantled it in 2018, but easy to say there's a person who saw a thing that others missed.
(edit: oops, I said that already. sorry, it's been a week. only just saw this reply.)
the big win with remote work is not selling off commerical real estate but being smart enough not to buy it in the first place. or to found a screensharing and video chat company. so a big winner there is Zoom. and a whole set of winners would be the companies who were already doing remote work and didn't have to skip a beat.
other companies which saw a boost from the pandemic: literally all of e-commerce. every sketchy ad on Instagram selling a $10 product from Alibaba for $50. and the platform they ran on: Shopify. which of course overhired when it saw a huge boom in traffic, and now has had to correct that overhiring.
However, I was not addressing that.
