Microsoft reportedly cuts off Bing data for rival AI chatbots

Renting someone else's kitchen to cook dinner is fine, until you start selling takeout across the street and competing for their lunch crowd.

Microsoft has warned at least two search engine rivals that it will completely revoke their access to Bing's search index if they keep feeding that data into their own AI chatbots, according to a report from Bloomberg.

Feeding rival bots with Bing data

Crawling the entire public web to maintain a real-time search index is astronomically expensive. Because of that hurdle, only a few players in the world do it at scale, and Microsoft has long monetized Bing by licensing its search data to other platforms.

Partners including DuckDuckGo, Yahoo, You.com, and Neeva rely on Bing's search index to varying degrees. While DuckDuckGo blends Bing data with its own crawlers, smaller upstarts like You.com and Neeva rely heavily on Bing's index to avoid the crushing computing and storage costs of scraping the web from scratch.

Trouble started when these smaller engines decided to build their own AI layers.

DuckDuckGo recently launched DuckAssist to summarize answers using Wikipedia. You.com already features an interactive AI search chatbot, and Neeva rolled out its own AI-powered summaries with inline citations.

Sources told Bloomberg that Microsoft views using its search data as fodder for conversational AI tools as a clear contract violation. Microsoft stated that it is actively enforcing its terms and working directly with partners who are out of compliance.

Why it matters

If you have been enjoying fresh AI search alternatives like You.com or DuckAssist because they feel cleaner and less ad-heavy than Google or Bing, keep an eye on them. Without access to Bing's massive web index, these independent services will either see their answer quality crater or face massive bills trying to crawl the web alone, which could force them behind paywalls.

For the AI industry, this move signals where the real moat lies. Large language models are quickly becoming commoditized, but real-time grounding requires a fresh, comprehensive web index. Right now, outside of Google, Microsoft holds the only major global pipeline in town.

We think Microsoft's defensive play is shrewd but ruthless. The company poured billions into OpenAI to make Bing Chat powered by GPT-4 its flagship comeback, and it makes zero commercial sense to subsidize rivals at wholesale rates. However, pulling the rug on smaller innovators risks drawing regulatory scrutiny and reminds everyone just how dependent the new wave of AI startups is on legacy infrastructure giants.
