Instead of the some of the posts I have seen about the ad, I chose to ask for answers instead of speculating and making up my own. So, I asked Christopher Chu. Here is his response:

I can confirm the brief ad. It’s not a marketing blitz unlike what has been talked about online. It is a small advert meant to introduce the ticker symbol of POET to new audiences in the US. Ergo the US ticker symbol and not the Canadian.
Warm regards,
