Owed a billion dollars in Nvidia stock

A former member of NVIDIA's Technical Advisory Board claims the company misinterpreted his 1993 stock option agreement in 1996, resulting in him receiving only 62.5% of his vested shares instead of the full 100% he was entitled to. When accounting for subsequent stock splits, the author asserts he is owed approximately 4.5 million shares, which would be worth roughly a billion dollars at current valuations. The dispute hinges on whether the vesting schedule was quarterly (one year) or annual (four years), with the author's original agreement specifying quarterly installments.
