Cursor co-founder Michael Truell said OpenAI represents just 5% of Cursor’s traffic, according to Techmeme’s summary of an Amir Efrati report in The Information. The same summary says Truell told The Information that Cursor had trusted OpenAI to be “neutral.” The provided item does not include the full context for that remark, and the feed summary is truncated before it completes OpenAI’s stated action. The headline also says Elon Musk responded that he “couldn’t care less.” The provided material does not specify the full exchange or what, precisely, Musk was reacting to. For now, the defensible takeaway is narrow: Cursor is publicly framing OpenAI as a small share of its traffic, while also suggesting it had relied on OpenAI’s neutrality. The story remains single-source in the material provided here, and a key OpenAI detail is incomplete. Who benefits: Cursor benefits if customers and partners accept that OpenAI is not a major traffic dependency. Alternative model providers could also benefit if buyers focus on supplier neutrality, but the provided item does not name them. Who's exposed: OpenAI is exposed to scrutiny over whether developers view it as a neutral platform partner. Cursor would be exposed if the missing OpenAI action materially affects users, but the provided summary is incomplete.
