There is no global semiconductor market. Saying it exists is the same thing as saying that global vehicle market exists and Boeing competes with Ford in making the best selling vehicle.
There is, however, "consumer chips foundry market", which is dominated by TSMC with 55%+ market share. And TSMC's market share is limited only because of their production capacity.
A vehicle is a finished good. A semiconductor is a semi-manufacture. Comparing it to a finished good with an end-user purpose is nonsensical. You could compare the global semiconductor market to, for example, the global steel market.
Semiconductor market is PARTIALLY finished good, if we consider creators market (gigs economy), where sell microcontrollers (RPI2040), and some other semiconductors.
It is market of small series custom devices, prototypes (like Oculus Rift), aftermarket upgrades, like cars tuning.
Yes, creators market is not too large, total number of sells just around million, but it exists.
BTW it is interest question, how large part of steel market also belong to creators market, if it is larger than semiconductor creators market.
