not all companies can create a big price increase like Elon Musk did this year, but there are other giants that could have the same big impact on the price and in my opinion are: Ebay, Netflix and the most important of them is without a doubt: "amazon and Jeff Bezos". if these companies adopted bitcoin publicly then the bitcoin price would be over $130,000
I think also from Asia we have big companies that if they suddenly embrace Bitcoin in a big way (the same way that Tesla did) then we will see a lot of craziness happen.
I bet you,,, if Jack Ma and Alibaba suddenly announces even 10% of their portfolio goes into BTC, it will create a huge FOMO among Chinese investors like never seen before.
