3 weeks after the "as soon as Friday" news, OpenAI has followed Anthropic and confidentiality filed their draft S-1. But they sure don't sound confident about it. Whole post in full (sans legal fine print):
We recently submitted a confidential S-1. We expect it to leak so we’re just announcing it. We have not decided on timing yet; it may be a while because there are things we want to do that are likely easier as a private company. But it’s a complicated set of tradeoffs and this gives us the option to go public sooner if that ends up being best.
May, likely, if... Those are some weight-bearing subjunctive clauses.
