A lot of people think that Apple can get to the point of being a trillion dollar company somewhere in the near future. The only reason why they think this might be possible is due to how great the company is. Currently, the market cap of Apple is somewhere above $815 billion. This suggests that it would only need about $185 more to get to the trillion dollars point. This would mark for an increase of only 23% of their value to get there.
These are approximates though, but still deliver the point. Apple could certainly become a trillion dollars company sooner or later. This prospectus took a blow with IphoneX and the decreasing sales of the Mac but Apple still has a chance if they innovate.
