With their roles advising on the historic Saudi Aramco IPO, White & Case and Latham & Watkins have had a front-row seat for what may still wind up being the biggest offering in history.

But given the deal's twists, the backdrop of royal intrigue, the stakes and the secrecy involved, no one is going to mistake this one as easy money for the lawyers.

For one thing, as The Wall Street Journal reported on Friday, the changing valuation of Saudi Aramco (from about $2 trillion down to $1.6 trillion to $1.7 trillion) and the size of the listing (from 5% of the company down to 1.5%) have made for a moving target.

Then there's the shifting politics and personnel – with Prince Mohammed bin Salman gradually sidelining more cautious Saudi players during his long quest for an IPO, per the Journal's account.

For White & Case, which is advising the company, it's hard to imagine a more internecine backdrop for a major client representation – especially with so much money in the balance. Despite the slimmed-down offering, the top valuation of $25.6 billion is still expected to beat Alibaba's $25 billion IPO in 2014 as the largest of all time.

For Latham, which is advising the joint financial advisers, coordinators, bookrunners and underwriters in relation to the international offering, Saudi Arabia's about-face on who will be allowed to purchase institutional shares – tilting the IPO toward local and regional investors – transforms the scope of the representation.

The international banks are certainly going to take a hit as Bank of America, Citigroup, Credit Suisse Group AG and Goldman Sachs have all been told to submit their orders for the IPO through two local Saudi lenders, Samba Financial Group and National Commercial Bank, as well as HSBC Holdings, rather than coordinating orders themselves.

What do the individual lawyers on the deal make of all this? Not surprisingly, they aren't saying. The firms declined to identify the partners involved or to comment on their work. The IPO prospectus gives only the firms' names and general roles. The email addresses assigned to many of the advisers – variations on "project alpha" – signal how careful the parties have been about leaks.

The secrecy doesn't seem to bother some institutional investors, though. Reuters reported on Thursday that the institutional tranche of ARAMCO's offering was oversubscribed. As of Thursday afternoon, the retail portion saw $2.67 billion in orders.
