Tesla (TSLA) CEO Elon Musk may not have spelled it out explicitly, but his utterances in the company's latest earnings call gave enough hints that a merger between SpaceX (SPCX) and Tesla may be on the cards sooner rather than later. In response to a question on the subject, Musk responded, "As you can tell from the many collaborations on so many fronts with SpaceX, there's more and more overlap, especially with Terafab; that's really going to be a gigantic project. But obviously, we can't talk about combining companies and that kind of thing on an earnings call. It's got to be done with the appropriate process."
So, it's just that the forum was not appropriate and maybe not grand enough for such a huge announcement from Musk.
