It was fraud.
It's a 40 page read but the synopsis is extreme corporate fraud. There is no intense legal wording. It's very easy for the average person to understand.
SpaceX basically found that Cuttell was funding the IHRA by over-charging 400-800% over the agreed upon subcontractor markup as well as hiding IHRA expenses in invoices for datacenter work, then started avoiding audits and eventually SpaceX started digging into how ridiculously lavish the IHRA events were given the series' historical instability and strange spending spree optics (someone did their homework).
Even the xAI/IHRA coats Cuttell can be seen wearing in some photos, were against the contract terms and xAI claims damaged the company's reputation as it made people think there was as master plan to sell tracks and turn them into data centers (there wasn't). This is mentioned specifically as damaging xAI's reputation and they link specific Reddit posts.
Cuttell was just an insane drunk/sociopathic fraudster stealing money from Elon thinking he wouldn't notice.
That's what the suit spells out.
Everyone who got paid prize money or paid for their services during IHRA events, was paid with stolen money.
