There's almost an "infinite" supply of RP2040 chips:

In a recent episode of Tom's Hardware: The Pi Cast, Raspberry Pi CEO Eben Upton revealed that 10 million RP2040 chips have been made since 2021 and that there could be more Raspberry Pi stores opening in the future.

Tom's Hardware Editor-in-Chief and The Pi Cast co-host Avram Piltch asked Upton "Why are there no shortage of RP2040 based products?" and Upton's answer "We took some big risks" lead to the revelation that Raspberry Pi purchased 500 wafers in 2021.

From a wafer, the yield is approximately 2000 die for 30mm. Newer chips, such as those in the Raspberry Pi Zero 2 W and Raspberry Pi 4 use a 45mm square die, respectively the BCM2710 and BCM2711 packages. From a wafer Raspberry Pi expect to make 1400 die.

Upton then does the math and from 500 wafers, each yielding around 21,000 die, there are around 10 million RP2040 chips.

[...] This "stockpile" of chips from 2021 are what many of us keen Pico users are currently consuming, be it in the form of Raspberry Pi Pico , Pico W or third-party boards. Upton then talks about what is "effectively an infinite supply [of RP2040]" based upon how many die can be created per wafer. This is a refreshing statement, given how global supply chains have been hit by the pandemic.

    That might be part of it, but the main reason from what I have been reading the last few years is that it is because nearly all of the Pico is made domestically. In contrast the normal credit card sized Raspberry Pi which still had many components made overseas where it got caught up in the supply chain fiasco that everyone else has gotten caught in too. Production is ramping up for the general purpose Raspberry Pis again [raspberrypi.com]. A possible Raspberry Pi 5 won't be around until at least 2024 [tomshardware.com] so that production can focus on the backlog demand for the 4B, 3B, 3A, etc.
