Taiwan ranked first globally in semiconductor foundry market share.
This statistic shows Taiwan’s central position in chip manufacturing with one unusually concentrated market share. A 78.1% foundry share means the island was not merely a participant in semiconductor production but the dominant location for contract chipmaking. The rest-of-world comparison makes the concentration visible without adding extra narrative.
