The first market-maker has to verify that a company's financials are in order. Then virtually all other market-makers are allowed to 'piggy-back' off of the validation made by the first market maker so that they too can make a market for the security without having to do all of the same validation work.
Note point 1) above, how a market maker can do that without the company's financial information being public (yet).
Also note, the amendment that allows for this has been adopted by the SEC.
