Continue the research until the result would be self-funding.

That's how researchers work. First you pour resources into it, then it might provide you with something sellable. Eventually. Maybe. Or not.

So, no business model.

Yes, no business model. Many things don't have it. Even the Sun.

Looks at it loosely: Well it looks like cool tech, and the first to offer it might have a new market all alone and can earn money and....

puts on tin hat have you looked around lately? Being able to directly access brains and probably inject God knows what signals to maybe be able to alter behavior of people and/or literally brainwash them is a sure way to get funding in late stage capitalism. [They] just want to be on the "correct side" of this. [They] just want control!

Is the sun a business?

A research company isn't a business either. Even if the formal de jure blabbering states otherwise.

So Neuralink isn’t a commercial company?

De facto -- no. Research project.

Sell brain-computer interfaces to people. I'm not saying that Neuralink will ever get there or that it's a good idea but the goal is to improve on the way we communicate with computers. My guess is that Elon's vision is some Neuralink clinics that for small price drill a hole in your skull and implant a chip. The $9B valuation is obviously just pure fantasy at this point and the $600m invested is probably from some billionaires that don't know what to invest in anymore.

I'd rather die than let Elon Musk put shit in my brain.
