In the wake of earlier reports that Google would make some heavy changes to its Chrome browser concerning data-privacy protections, which would affect how ad-tech vendors operated within it, ad-tech companies stock prices were down sharply on Tuesday.

Now analysts believe these tighter restrictions won’t occur.

John Egber, security analyst for Stifel Nicolaus, according to Seeking Alpha, said: "If Google were to decimate its ad-tech competitors’ business models overnight by imposing changes as restrictive as Apple’s ITP, the company could face even more antitrust scrutiny than it is already dealing with."

In addition, Dan Salmon, an analyst at BMO, warned investors not "jump to assumptions" on any potential changes.

Investors are concerned that Google would make big changes following previous data-privacy changes made by Apple's Safari and Mozilla's Firefox.
