100-word summary
OpenAI tacked another $10 billion onto its mega-round just four weeks after closing $110 billion in February, bringing the total haul to $120 billion. The March extension pulled in Andreessen Horowitz, Abu Dhabi's MGX, and T. Rowe Price alongside earlier backers like Microsoft. The money's earmarked for data centers and compute, the unsexy infrastructure that's now burning cash faster than anyone expected. A $120 billion round used to sound like science fiction. Now it's looking more like table stakes for staying in the race to build frontier AI models that require unfathomable amounts of computing power.
