JPMorgan Chase, Bank of America, Wells Fargo, and PNC Financial are in preliminary discussions to acquire Fiserv’s STAR debit payments network, a piece of infrastructure valued at roughly $15 billion that processes around 3 billion transactions annually. The talks, first reported by The Wall Street Journal, signal that America’s biggest banks want to own the rails their money already rides on.
Fiserv inherited the STAR network when it bought First Data in 2019. Fiserv shares have cratered from above $200 in 2025 to the $50-$53 range, making the math suddenly more interesting for potential acquirers.
Why the STAR network matters
The strategic prize here isn’t just transaction volume. It’s the Durbin Amendment, a 2010 regulation that caps interchange fees on debit transactions for banks with more than $10 billion in assets. Those caps have been a persistent thorn for large banks, limiting the revenue they can extract from each swipe.
Owning the STAR network could give these banks a way to restructure how debit transactions are routed and priced. By acquiring a proprietary network such as STAR, these institutions could gain autonomy over transaction routing and move toward potentially charging higher fees, akin to the advantages enjoyed by prominent credit card networks.
