Elon Musk helped start OpenAI.
Resolved true The record shows it happened or was so.
Factual: Statements about the present or the past, checked against the record: did they hold up?
What would count as true or false
True: founding records show Elon Musk was a co-founder, co-chair or initial funder involved in creating OpenAI in 2015. Mostly true: he was involved at the founding, but in a narrower role than 'helped start' suggests (for example, mainly as a funder). Mixed: his involvement started only after the founding, but early on. Mostly false: his role was marginal, or mainly a pledge he did not fulfil, with no role in creating the organization. False: records show he had no part in founding OpenAI.

E4 OpenAI and Elon Musk OpenAI · 5 March 2024 Own record
“In total, the non-profit has raised less than $45M from Elon and more than $90M from other donors.”
Reasoning
OpenAI's December 2015 founding announcement names Elon Musk as co-chair alongside Sam Altman (E1) and lists him among the donors supporting OpenAI at launch (E2). An independent account in The Conversation (E3) says Musk was part of the founding group with Altman, Brockman and Sutskever, and that the group pledged $1 billion. OpenAI's 2024 post (E4) confirms that Musk actually gave funds, putting the total at less than $45M. Taken together, these records meet the "true" criterion: he was a co-founder, co-chair and initial funder.
