How do they profit? There must be a cost somewhere? Another reply mentioned spreads - still a cost (you lose money when you trade).

AUM, managing high wealth clients, running their own funds with expense ratios (also some of the lowest in the industry), uninvested cash, etc... Retail trading is commoditized now.
Anyone who really cares about spreads will be using limit orders. Otherwise you're talking about pennies on highly liquid shares.
The fact that we're even discussing the possible spread differences between market makers shows just how commoditized retail trading has become.
Low cost brokerages mostly earn money from the interest rate differential, ie what they pay from your un-invested balances vs what interest they pay you.
They also earn some money from 'payment for order flow'.
the sell order flow to market makers who gobble up the other side of bad retail trades
I highly doubt market makers are in the business of betting against retail traders.
I suspect they're in the business of collecting the spread on lots of small trades that they can assume are largely random.
What you described is how you bet against retail traders. The bet is that they have no edge so it’s safe to run tight spreads and nice pure market making algos that assume random behavior at volume.

Which means that your cost is market maker's spreads instead of fees. Still a cost to you.
Nope, this is one of the counterintuitive things about people paying RH for order flow. Market makers can offer tighter spreads when they know it’s a pool of dumb money.
