Jeff Bezos, the brains behind online retail behemoth Amazon, is making headlines again with another share sale.

This time, the Amazon founder is letting go of 25 million shares in the tech giant, netting him a cool $5 billion, or roughly Sh641 billion.

Interestingly, this divestiture follows hot on the heels of Amazon's stock price reaching an all-time high.

It's also worth noting that this isn't Bezos' first foray into share sales – back in February, he announced a similar move worth around $8.5 billion.

The reasons behind these sales haven't been officially disclosed, but speculation is rife.

Some believe it could be a way to diversify his wealth, while others suggest he might be using the funds to fuel his other ventures, like space exploration company Blue Origin.

Whatever the motive, one thing's for certain: this significant share sale is sure to send ripples through the financial world.
