• Talks about investment is not enough.

• Statements beyond 2025 deadline applying retroactively don't count

• Future purchase is not enough, must be a confirmed (official communications from either party) state of the world.

• If Apple or OpenAI change name, the question applies to the new entities.

• If paid with something else than cash, e.g. a share swap, it counts as an investment as long as Apple gets share stakes in OpenAI.
  

Let me know if further clarifications are needed.

I might trade in this market, seems straightforward enough.
