Summary · why it matters

AI training-data startup AfterQuery has reportedly raised a round valuing it at $3.2 billion, just five months after its $30 million Series A at a $300 million valuation. That marks a more than tenfold increase in under half a year, and according to Y Combinator partner Gustaf Alströmer, it is the fastest any startup has gone from launch to unicorn status in the accelerator's history. The founders, aged 22 and 23, attended Y Combinator's Winter 2025 cohort just 18 months ago. In April, the San Francisco company reported an annualized revenue run rate of $100 million and counts Nvidia, Legora, and Korean AI lab Motif Technologies among its customers. AfterQuery trains models and agents to emulate professional workflows, distinguishing itself from peers like Mercor and Scale. Forbes first reported the round; AfterQuery could not be reached for comment.

Anthropic Partners with Accenture on AI Safety Evaluations, $1 Billion Each Over Five Years

Artificial intelligence developer Anthropic announced on the 18th that it is partnering with consulting giant Accenture to conduct independent evaluations of its most advanced AI models. Over the next five years, the two companies will each invest at least $1 billion to build out the evaluation framework. Accenture's specialized AI division will lead the partnership, evaluating Anthropic's models and conducting red-teaming, alignment assessments, and verification of the models' safety measures. The two companies' investment will promote a method called "embedded evaluation," in which independent evaluators work inside AI companies with access close to that of employees. Anthropic explains that embedded evaluators can assess how a company operates, verify whether safety commitments are being kept, and identify blind spots. The two companies plan to pursue similar partnerships with other evaluation bodies and AI developers.

SpaceX Weighs Buying Data From Failed Startups to Feed AI

SpaceX has held internal discussions about buying customer, operational and other data from troubled or failed startups to feed its AI efforts, according to Bloomberg. The talks remain informal and may not result in any transactions. SpaceX has already used information from Elon Musk's social network X, along with internal AI tutors, to help train and improve its software, and reportedly paused hiring for those tutors earlier this year. The push comes as AI becomes a larger part of SpaceX's spending: the company invested $15.8 billion in AI-related capital expenditures during the second quarter, while its AI business generated $2.56 billion in revenue during the period but posted a $1.26 billion operating loss. Investors will be watching whether that spending can eventually turn the company's expanding AI operation into a profitable business.

Nokia Expands Microsoft Partnership for AI-Driven Network Automation

Nokia Corporation is expanding its partnership with Microsoft Corporation to build an agentic, unified data foundation aimed at helping telecom providers scale artificial intelligence-driven operations. Under the agreement, Nokia Data Suite integrates with Microsoft Fabric, combining telco-specific data products with unified analytics, governance and AI capabilities across cloud, hybrid and on-premises environments. The company is initially applying these capabilities to autonomous Voice over New Radio assurance, where AI agents detect network anomalies, analyze service issues and recommend corrective actions. Nokia faces competition from Ericsson, which expanded its Intelligent Automation Platform to support automation across radio and core networks, and from Cisco Systems, which is integrating AI agents into its networking portfolio. Nokia shares have soared 123.6% over the past year compared with the industry's 20.6% growth, and the stock trades at a forward price-to-sales ratio of 2.42 versus the industry tally of 4.93.
