ICBC's market capitalization was $315 billion on Thursday, 11 percent more than Wells Fargo based in San Francisco.
According to analyst Steven Chan, of Maybank Kim Eng Securities Pte in Hong Kong, Chinese banks' gains may be supported by monetary easing lowering their funding costs and limiting bad loans, the report said.
China has cut interest rates and lenders' reserve requirements twice since November.
"The next round of the rally is likely to be related to some of the foreign institutional investors realizing that they've been too pessimistic about China's banks," Chan said.
ICBC reported a net profit rise of 5.1 percent year on year to 276.29 billion yuan ($45.29 billion) in 2014.
