COMEX is the world’s most liquid futures market for gold and silver. As of this writing, it trades more than 400,000 gold futures and options contracts every day, making it the most active metals exchange on earth. So, what is COMEX? It’s a futures market that sets the spot price you see quoted on financial news, your dealer’s website, your IRA statement, and just about everywhere else.
This post covers how COMEX works and what that means for anyone who owns physical metals.
What COMEX stands for and what happens there
COMEX is short for Commodity Exchange Inc., which was created in 1933 from the merger of four New York commodity exchanges:
- The National Metal Exchange
- The Rubber Exchange of New York
- The National Raw Silk Exchange
- The New York Hide Exchange
Today, it operates as the metals division of CME Group, the world’s leading derivatives marketplace.
The COMEX division trades futures contracts and options on precious and base metals: gold, silver, copper, and aluminum. Gold and silver are by far the most heavily traded. Gold futures contracts alone clear more than 400,000 trades a day, with silver running second by volume.
CME Group is headquartered in Chicago, but the COMEX name carries over from its New York roots. There is no physical trading floor today. Almost all activity happens electronically through the CME Globex platform.
How COMEX sets the price of gold and silver
The price of gold you see quoted today, whether on a financial news ticker, your dealer’s website, or your IRA custodian statement, traces back to COMEX. Spot prices are calculated from COMEX futures activity, with contributions from the LBMA on the over-the-counter spot market in London.
When buyers and sellers trade enough volume on COMEX, the resulting prices become the global reference. As the most actively traded metals exchange in the world, COMEX sets the benchmark that other exchanges and dealers calibrate against. This is why a price quote from a coin shop in Phoenix and a wire transfer settlement in Singapore both move roughly in sync during the trading day.
As of this writing, COMEX is the dominant venue for gold and silver price discovery. Trading is overseen by the Commodity Futures Trading Commission (CFTC), and the role is unlikely to change soon, despite growing volume on the Shanghai Futures Exchange and other regional markets.

How a COMEX futures contract works
A COMEX gold contract is a standardized agreement. The buyer commits to receive 100 troy ounces of gold at a future date, and the seller commits to deliver it. Silver contracts cover 5,000 troy ounces. Copper contracts cover 25,000 pounds.
To enter a contract, a trader doesn’t pay the full value upfront. Instead, they post a margin deposit, which is a fraction of the total contract value. This is leverage. A small price move on the underlying metal can produce a large gain or loss on the trader’s account, which is why futures markets attract professional traders and speculators, not long-term holders. For producers and consumers of metals, the same contracts work as a hedging vehicle for managing price risk.
Most contracts are closed out before expiry by an offsetting trade or rolled forward into a later contract month. Only a small percentage of contracts are held to delivery.
Why most COMEX contracts never result in physical delivery
In a given month, less than 5% of open COMEX gold and silver contracts result in physical delivery. The rest are closed out by an offsetting trade or rolled into a later contract month before expiry.
This is not a flaw in the system. It’s how futures markets are designed to work. The contracts exist for price discovery and risk management, not for moving metal. A jewelry manufacturer might use COMEX to lock in the price of gold they’ll need six months from now, never intending to take delivery from the exchange.
A hedge fund might trade contracts to express a view on the dollar, with no interest in storing 100-ounce bars. Most individual investors who participate in COMEX do so indirectly through ETFs or brokerage accounts that trade futures, not by holding contracts themselves.
In practice, this means the price the world uses to value gold is set by a market where most participants never touch the metal. That structural fact has implications for anyone who holds the physical asset.
Paper exposure vs. physical ownership
Owning a COMEX futures contract and owning a gold coin are different things. Here’s how they compare:
| Paper exposure (COMEX futures, ETFs) | Physical ownership (coins, bars in your possession) | |
| Counterparty risk | Yes (exchange, custodian) | None |
| Leverage | Yes, margin-based | No |
| Storage | Not your problem | Yours to handle (home safe or depository) |
| Liquidation | Same-day market order | Phone call to your dealer |
| Use case | Trading, hedging | Wealth preservation, generational holding |
| Settles in metal? | Rarely | It’s already metal |
What COMEX activity means for the physical metals investor
The spot price your dealer quotes today was set by activity in a market where most participants never take delivery. That isn’t a criticism of COMEX. Price discovery has to happen somewhere, and a deep, liquid futures market is one of the more efficient ways to find a price.
For the physical buyer, the meaning is direct. You are buying the same underlying metals that all the metals trading on COMEX is priced against. You just hold the underlying instead of a claim on it.
That distinction is the difference between counterparty risk and no counterparty risk. It’s the difference between a position that depends on the exchange remaining solvent and a coin you can hold in your hand. Both are exposed to gold’s price moves. Only one is exposed to nothing else.
Quick facts about COMEX hours, location, and contract sizes
COMEX operates nearly 24 hours a day on the CME Globex electronic platform. Trading runs from Sunday evening through Friday afternoon Eastern time, with a short daily maintenance break. There is no traditional pit-trading floor today.
The standard gold contract is 100 troy ounces, and the silver contract is 5,000 troy ounces. Copper contracts trade at 25,000 pounds each. CME Group, which operates COMEX, is headquartered in Chicago, though the COMEX name reflects its New York origins.
Final thoughts on COMEX
COMEX is the engine that prices gold and silver globally. It exists to facilitate price discovery and hedging by professional market participants. Physical ownership is how you participate in that price without depending on the engine itself.
