Snap could disclose its IPO pricing plans by the end of this week, sharing how much it hopes to be worth and how much ownership it is willing to give up.

Classic calendar: Snap filed its publicly-available S-1 document with the SEC on Thursday, Feb. 2, and there is then a 15-day waiting period before it's allowed to begin its roadshow (which usually coincides with publicizing pricing terms). That would work out to this Friday, with the actual IPO possible by early March.

Caution: These timelines are minimums (i.e., if Snap moves as fast a possible), but there is no indication that the Los Angeles-based company plans to take its time.
