AdTech Under Fire: Antitrust, Data Use, and Industry Shifts
Nebraska State Auditor Mike Foley has used location and purchase data — likely derived from commercial data sources — to identify and discipline state employees who used state vehicles for personal errands. Separately, the Belgian Competition Authority has opened antitrust proceedings into Google, citing concerns about the terms of certain Google intermediation services and possible differential treatment of users or competitors. A separate research note reports that ads which embrace negative reviews performed better in a Meta test, suggesting a creative tactic for brands. The roundup also flags brief industry items: reports of a large Amazon investment in OpenAI, an OpenAI employee firing for insider trading, potential FCC scrutiny of live sports rights, Paramount’s bid for Warner Bros. Discovery, and other media and M&A developments.
EU national antitrust proceedings into Google and increased regulatory scrutiny of data-brokering practices affect major platform behaviors, market competition, and privacy/data-usage norms across the adtech ecosystem.

AI Price War: OpenAI Gains Ground on Anthropic
The AI price war is intensifying, with OpenAI gaining significant ground on Anthropic among business customers. According to a Wall Street Journal report, spending on OpenAI and Anthropic models via the OpenRouter platform was nearly evenly split in September among roughly 120,000 companies using both, a shift from January when Anthropic held about 75% of that spending. OpenAI's aggressive price cuts on its GPT-5.6 lineup, including an 80% reduction on its smallest model Luna and 20% on Terra, are driving this change. Companies are increasingly prioritizing cost, combining multiple providers and using cheaper models for simpler tasks. Anthropic faces its own challenges, including capacity issues with Claude Code and data retention criticism. Both companies are preparing for IPOs, needing to demonstrate sustainable revenue to justify valuations exceeding $1 trillion.
