A confusing thing about fundraising and dilution is that the new shares don’t take away value from existing shareholders.
If each share is worth $1 at the valuation used in the raise, then an investor adding $100 million gets 100 million shares for it. The shares aren’t taken away from anyone, they're issued in exchange for the capital.
So ideally the dilution is neutral to the value of the equity. In practice this is highly variable because the valuations are fuzzy numbers used for the raise, but you get the idea.
If a company can get the same growth without raising, that would be better because the proportional ownership stays higher. However, the reason companies give equity in exchange for capital is that they need the cash for growth and can’t get it on better terms anywhere else.
