SoftBank Vision Fund and Alphabet are among the largest shareholders in Uber, which has filed for an offering that could value it at $100bn, a decade after it was founded.
SoftBank Vision Fund invested $1.46bn to take Grab's series H round, already backed by Toyota, Hyundai, Kia, Booking Holdings, Central Group, Yamaha, Ping An, Microsoft, Tokyo Century and KBank, to $4.5bn.
Booking Holdings has provided more funding for Didi as part of a strategic partnership, as the latter looks to spin off its vehicle services arm in an IPO sized at up to $1.5bn.
Entertainment producers like 21st Century Fox and Warner Bros have reportedly supplied $200m of an $800m round that will support high-budget, short-form video, as content continues to draw in big bucks.
The e-signature technology provider's shares have risen almost 50% since it floated on Friday, illustrating that IPOs are back with a bang for tech companies.
