Market makers: who's on the other side of your options trade

When you buy an option, who sells it to you? Usually not another retail trader who happened to want the opposite. Most of the time, it's a market maker.

What they do

A market maker continuously quotes both a price to buy (bid) and a price to sell (ask) on a contract. Their job is to provide liquidity — to be willing to trade with you whenever you show up, in either direction. In exchange, they earn the spread between those two prices.

That's the deal underneath every fill: they take on the risk of holding a position they didn't necessarily want, and the spread is their compensation for it.

Why this demystifies a lot

Once you see market makers behind the quotes, several things make sense:

• Spreads widen when risk rises — in volatile conditions or thin contracts, makers demand more cushion, so the gap grows.
• Your fill quality depends on competition — more makers quoting a liquid contract means tighter spreads and better prices.
• You're not being singled out. A wide spread isn't personal; it's the price of liquidity in that particular contract.

The practical lesson

You can't change how market making works, but you can choose where you play. Trading liquid, heavily-quoted contracts means tighter spreads and better execution. Wandering into thin, neglected strikes means paying market makers a premium for the privilege.

Knowing who's on the other side turns the spread from a mystery into a cost you can see, measure, and manage.
