They are talking about the radio chip that's on the Pico W. not the whole pico w.

I am asking about the radio chip. The last I checked, buying one from a distributor costs around $6. You would need to do a huge order to get the price down to $2.5 per chip. The required order quantity is so huge that distributors do not list it.

From https://octopart.com/search?q=CYW43439&currency=USD&specs=0.

Indeed the lowest price $2.551 from Arrow has a MOQ of 5000 but Newark does have it for a promotional price of $2.73 for quantities as low as 1.

It’s not $2.5 but that’s why it was quoted as ~$2.5 in my reply, since it’s in the ballpark.

Thanks. I had not known about octopart.
