> "Well-established protocols" can result in IPO prices being systematically set too low. Yes, theoretically a bank should be able to break the ranks, but all they would get for their trouble is smaller profits, and a potential lawsuit from investors. After all, they did diverse from the "established accounting standards" when pushing the IPO price up.
Assuming a roughly competitive market with n players that do not engage in direct collusion, if IPO prices are being set too low from the perspective of the companies IPOing, there's room for an additional player (n+1) to set their prices slightly higher. Assuming their ability to predict the risk on the opening bell prices is the same as the other n players' ability to predict risk, that bank will produce IPOs that are consistently favorable for the companies IPOing, and companies will choose that bank as their underwriter. Ceteris paribus, their profits would grow, not shrink.
There are factors that impede this from happening perfectly in practice - such as barriers to entry for the underwriters - which is (part of) what explains why this disparity won't trend to exactly zero. But it's wrong to say that banks would get punished by either companies or their investors for responding to this disparity by raising prices - the exact opposite would happen. And in itself, that still doesn't point to widespread collusion between banks, or even any sort of implicit conspiracy.
Not sure how you'd get that (n+1) business off the ground. Even with the current happy-go-lucky funding climate, I don't see much success in pitching the idea. "We'll take on the giant incumbents, by accepting additional risk on behalf of our clients, in return of reduced profits".
I agree that there would be a solid market demand for this company. The same way there would be much demand for a telecom/isp that provides more speed at reduced price. Consumer demand isn't always the only thing needed for a business to succeed, despite what pg says.

This is a thought experiment, designed to illustrate that auctions (which IPOs are - an auction between underwriting banks) converge towards the maximum price that individual participants would be willing to pay. You can easily extend this logic to any individual participant.
> in return of reduced profits
You keep saying "reduced profits". If you seriously believe that banks are artificially keeping bids low, then there would be no reduced profits - any individual bank willing to outbid the rest consistently would completely sweep the entire market, capturing all profits across the market of banks which underwrite IPOs.
Of course, this won't happen, because banks aren't artificially keeping bids low, which is the whole point. You can't just point at the fact that post-opening bell prices are greater than IPO prices to show that banks are colluding with each other, because that doesn't prove anything. The current prices are completely consistent with a competitive market.
