The $40 you left in Venmo earns PayPal money. You get none of it.

When you leave money in a Venmo or PayPal balance, it doesn't sit in a drawer with your name on it. PayPal pools every customer's idle cash into one giant managed account. As of September 2024, that pool held $39.2 billion: wallet balances, pending transfers, money in transit. It's your money. PayPal is just holding it for you.

Your $40 works the float. The interest bends back to PayPal. Your cut: $0.: Your idle balance · $40 sitting in Venmo · Pooled customer cash · $39.2B held, not owned · Invested float · govt securities, bonds, deposits · Interest income to PayPal · hundreds of millions (9mo 2024) · Paid to you · $0

This pool is called the float. PayPal doesn't let it sit still. It invests the money in government securities, short-term bonds, and bank deposits that quietly earn interest while you wait to spend or transfer. PayPal reported hundreds of millions in interest income through the first nine months of 2024, partly driven by this float. Your balance, meanwhile, earns you nothing. The longer your money waits, the longer the meter runs for them.

Idle money is never idle. Someone always earns interest on it. If it isn't you, it's whoever holds it.
