According to Bloomberg, SoftBank disclosed its ownership of an 'unspecified amount' of Nvidia stock as part of its announcement regarding $93 billion of commitments to its technology investment fund last weekend.

Last year, SoftBank acquired ARM Holdings, the British company whose processor designs are used in a huge range of devices - from smartphones and tablets, to notebooks, networking equipment, embedded devices, wearables, and many more.

The $32.6 billion acquisition was SoftBank's largest ever, but with growing demand for ultra-efficient, low-power chips around the world, analysts started to think it made sense.

However, a large holding in Nvidia puts the company in a strong position to dictate company direction. An Nvidia/ARM alliance would be an interesting and powerful team.
