OpenAI Acquires Rockset

Don't these M&As need to be cleared by regulators? Seems premature to tell your customers you're discontinuing your product before the acquisition has actually cleared (and, for that matter, passed OpenAI's due diligence).

According to [0] the acquisition has already been completed.

Tiny acquisitions which don't affect anything don't need sign off from any regulator. They likely signed the deal and closed it in one go.

How exactly does that work? Is there a formal threshold for when a regulator will want to take a look?

Yeah, the FTC and DOJ publish guidelines with thresholds, and you basically just follow them.

There are like 10k+ mergers and acquisitions done in the US each year (ballpark). It requires real analysis to figure if something should be blocked (practically none have any real effect on anything and shouldn't be) and there are only so many folks at the regulators who can do that analysis (and honestly... they aren't good at it...).

Usually no.

I’ve been around for a few M&A that horrendously fucked customers of the “acquired” company and the regulator doesn’t care. Even if the acquirer is under regulatory observation.
