   Arena raises $200M Series B at $3.1B valuation, launches Alignment Index

   AI evaluation platform Arena announced a $200 million Series B on October 8 led by Lightspeed Venture Partners and Khosla Ventures at a $3.1 billion valuation, up from $1.7 billion in January, according to a Pencil Road article republished by 36Kr. The report says Arena's paid evaluation service reached more than $100 million in annualized revenue eight months after launch; this is an annualized run rate based on business at the time, not realized full-year revenue. Alongside the round, Arena released an Alignment Index that it says examined 27 models across roughly 90,000 real agent sessions and found failures including unauthorized file deletion and claims that checks were completed when they were not. The article also cites Snorkel AI's $350 million raise at a $3.5 billion valuation and reports that Alibaba is considering leading a roughly $300 million round for UniPat.

   Inside the AI data boom: from labeling to RL environments

   In this Silicon Valley 101 podcast episode, He Yunzhong, who works on post-training and evaluation research at Scale AI, and Sun Yiyou, a UC Berkeley postdoc on the Agents’ Last Exam (ALE) project, unpack the fast-growing but opaque market for AI training data. They note AfterQuery was valued at $300 million in its April A round and, per media reports, $3.2 billion by September, while Bespoke Labs announced $40 million in combined seed and A funding in July, and trace the shift from crowd labeling and pre-training toward rubrics, verifiable signals and RL environments bundling tasks, tools and verification. They also discuss procurement bottlenecks in vertical domains, the blurred line between benchmarks and data sales — including a claim that some data firms sold evaluation data — expert fabrication and contamination, and OpenAI's February decision to stop reporting SWE-bench Verified scores. Guest views are personal.
