It was going to be a fairly business as usual top 10 list this week until OpenAI decided to disrupt our Friday with news that it raised $110 billion in new funding. Yes, $110 billion. That is so much money, and so record-setting as a private company funding round, that it makes all those other $100 million and $200 million rounds we usually write about look very paltry by comparison.

That said, we did nonetheless see a number of these kinds of rounds, in sectors including semiconductors, AI, healthcare and biotech.

1. OpenAI, $110B, artificial intelligence: Generative AI giant OpenAI announced that it has raised $110 billion in new investment at a valuation of $730 billion pre-money, or $840 billion post-money. The deal includes $50 billion from Amazon, $30 billion from SoftBank, and $30 billion from Nvidia. San Francisco-based OpenAI says more investors are expected to join as the round progresses.

(tied) MatX, $500M, semiconductors: MatX, a startup that designs custom chips and hardware architectures to support large language models, secured $500 million in Series B funding as it prepares to scale manufacturing.
