I personally don't think so based on my observation of the company over the past few years. I think they're in it for the long haul, as are their investors. However, I don't have much to back up my statement, other than Matt's ideals.

The firm holds a longer, (financially) non-optimal view; their handling stakeholders would be different if they were gunning for an exit. Instead, Wordpress seem to be presenting for (private; less volatile) investment (but I don't know what for?).
