AI infrastructure startup Baseten raises $1.5 billion in a Series F funding round, according to multiple outlets. The round values the company at up to $13 billion. Australian venture capital firm Blackbird VC is reported as making the largest or record bet by an Australian investor in this context, contributing a substantial single investment. The news coverage frames the valuation as arriving relatively quickly, with some reports noting the company reaches the $13 billion figure about 18 months after an earlier stage or milestone. Across sources, the core details remain consistent: the funding amount, the Series F classification, the valuation range (up to $13 billion), and Blackbird’s involvement as a standout backer. The articles do not present differing figures for the main terms, though they emphasize the prominence of Blackbird’s investment. The reports collectively position Baseten as focused on AI infrastructure, and they indicate investor confidence reflected in the scale of the round and the valuation cap or ceiling referenced by media.
