Top money for US chain (9)

I believe the answer is:

starbucks

'us chain' is the definition.
(US coffee chain)

'top money' is the wordplay.
'top' becomes 'star' (eg a top player is a star player).
'money' becomes 'bucks' (informal term for dollars).
'star'+'bucks'='STARBUCKS'

'for' acts as a link.

I've seen this clue in The Guardian.
