Kalshi opens a new up-or-down copper window every quarter hour, Sunday 3 PM to Friday 2 PM Pacific. This page is that contract: the price to beat in dollars per pound, copper now and the gap in cents, and what a stake pays after the fee, with Agent Nelly's call. The market is thin, about a twentieth of gold's volume, so expect a wider spread.
The odds and payout on this page still update on their own.

Trading 15-minute markets moves fast. A setup can change in minutes, so I want the right information in front of me before I make a decision.
That’s why I use PM Countdown. It puts the indicators and market information I care about in one place, so I can review the setup, understand the price being offered, and decide whether it’s actually worth taking.
The reset is part of my process too. After a big win, a tough loss, or too much time at the screen, five minutes away helps me come back focused instead of chasing the next trade.
I don’t need to trade every market. I want the right setup at the right price. PM Countdown helps me stay disciplined and wait for it.

Is the next trade about getting that loss back?
Do I know today’s loss limit in dollars?
Have I reached it?
Would I size the next trade bigger than I planned this morning?
Have I moved some of it to my bank account?
Does money I just won feel easier to risk than money I put in?
Would I size up the next trade because I’m up?
Do I know when I’m stopping today?
Have I stood up in the last hour?
Have I eaten something in the last few hours?
Did I get a normal night’s sleep?
Is it later than I planned to stop?

How to read this Copper desk
Four numbers, then a decision
Every tab on this page ends in the same question: is the price you would pay below what you think this copper contract is worth, after the fee?
The copper price Kalshi publishes when the window opens: the 1-minute close on Pyth’s copper price at the open, in dollars per pound to five decimals, like $6.73534. It is set then and does not move. Up wins if the 1-minute close at the end of the window is at or above it, so a window that ends exactly level settles Up.
COPPER now and the gap
Copper from Hyperliquid's copper market, lined up with Kalshi's starting price each window: at the open it reads the price to beat, and every move after that is the market's own move. The gap reads in cents per pound. Kalshi settles on Pyth’s copper price, not on this feed. In our check of 198 settled windows the two agreed on direction 98% of the time once copper had moved about a third of a cent, and not much better than a coin flip under an eighth of a cent, so treat a gap that small as a tie.
Up and Down prices
Up is the Kalshi ask for YES on this copper window. Down is 100 minus the YES bid, which is what NO costs you. A price in cents reads as the market's chance in percent, so 44¢ is the market saying roughly 44%.
If you're right, if you're wrong
What your stake buys at the current ask, after Kalshi's taker fee. If you're wrong the whole stake is gone at the close. On a market that reopens four times an hour that is the number to decide first, not last.
15m
Real contract. Kalshi opens a fresh up-or-down copper window every quarter hour while copper trades, Sunday 3 PM to Friday 2 PM Pacific with a short daily break, and settles it on the 1-minute close on Pyth’s copper price. That one contract is what the right-hand panel reads on every chart tab.
One close, no average
How it settles. The bitcoin contract averages the last 60 seconds of its index. This one does not: it compares one 1-minute close at the end with one at the start. The last minute matters more here, so the panel says so instead of averaging it.

Copper's scale
Why copper moves in cents and the line has five decimals
Copper is priced in dollars per pound, near $6.70 this October, and Kalshi writes the price to beat to five decimals, like $6.73534. A typical 15-minute window moves about 0.6 cents, so this page shows the line and copper now to five decimals and the gap in cents.
5 decimals
The line. The 1-minute close on Pyth's copper price at the window's open, in dollars per pound. The close at the end of the window settles it and becomes the next window's price to beat.
Cents
The moves. At $6.70 a pound, a 0.1% move is about two thirds of a cent. A gap of 0.42 cents with a minute left is a real lead on copper; on gold the same share of the price would be a few dollars an ounce.
Lined up
Copper now. Hyperliquid's copper runs about half a percent under Pyth's level, 3 to 4 cents a pound. At each open this page adds that difference back, measured from Kalshi's price to beat and Hyperliquid's close for the minute that ends at the open. Copper now starts every window at the line, and every move after that is the market's own.
Ties
An exact tie. Up pays when the closing price is at or above the price to beat, so a window that ends exactly level settles Up.
Thin market
A small book. A typical copper window trades about 19,000 contracts, roughly a twentieth of gold's (the median of the last 200 windows). The spread can be wider than on gold, and a large order may not fill at the price shown.

Fees on a 15-minute copper window
A coin flip needs a real edge
Many copper windows trade near 50¢, and that is exactly where Kalshi's fee is at its worst. You pay the spread and the fee before you make anything, and this market reopens four times an hour, so the cost of trading every window adds up faster than the edge does.
Worked example: 100 Up contracts on a copper window at a 51¢ ask
These are the arithmetic, not a quote from the live copper market. Cost is $51.00 plus a $1.75 fee (0.07 × 100 × 0.51 × 0.49, rounded up to the cent), so $52.75 in total. They pay $100 if copper finishes on the right side of the target. You need to be right more than 52.75% of the time just to break even, and selling before the close adds a second fee.
Fee formula: Kalshi's taker fee, 0.07 × contracts × price × (1 − price), rounded up to the cent; resting limit orders can pay less. The arithmetic uses Kalshi's standard taker fee, the schedule the gold and bitcoin windows carry. The published write-ups were written about bitcoin: predictionmarketspicks.com calls the spread plus fees on a near-coin-flip contract "a steep, constant drag", and TheLines puts the fee at 1¢ to 2¢ per contract.
Sizing
¼ Kelly, capped at 5%
Full Kelly for a copper contract at price P when you believe the chance is q is (q − P) ÷ (1 − P). We use a quarter of that, never more than 5% of your bankroll, and nothing at all when the number is zero or negative. Four copper windows an hour is four chances to overstake.

Ignores fees, which lower it further. Your chance is a guess; if it's wrong, Kelly oversizes. Source: betstamp on Kelly, which advises never risking more than 5% on one bet.
Take a break between windows
A new copper window every 15 minutes isn't a reason to trade every one
Fast markets reward slow rules. Copper gives you up to 96 of these windows a day and you do not have to be in any of them. Decide how many you will trade and your loss limit for the session before the first one, and stop when either runs out. If you lost the last copper window, sit out the next one.
Set a money limit for the session before you start, and keep it.
Never raise the stake to win back the last window.
Skip any copper window where you can't say why the price is wrong.
Walk away after a set number of windows, win or lose.
TheLines' guide to these markets makes the same point: "Take breaks. Avoid rushing into consecutive trades."
