Groq has closed a $350 million Series A at a $3.5 billion valuation, led by Disruptive with planned Nvidia participation, following a $650 million raise in June.

The new capital is earmarked to support customer workloads on Nvidia accelerated computing clusters, with Groq targeting more than 200 megawatts of capacity by end of 2027 from a current 54-megawatt footprint.

Reddit began a limited test on August 17, 2026, converting selected English-language text posts into audio and video formats, with at least one documented example using AI-generated voices to narrate an r/boardgames post and its top replies.

Reddit has not disclosed which communities are included, how posts are selected for conversion, any creator payment terms, or the metrics it will use to decide whether to expand the test.
