Kalshi · KXETH15M · ether up or down · 1m to 1W charts
Ethereum 15-minute desk
Kalshi opens a new up-or-down ether window on every quarter hour. This page is that contract: the target to beat, live Coinbase ETH-USD candles from 1 minute to 1 week, and what a stake pays after the taker fee. Changing the chart tab changes the candles only, never the ETH contract in the panel.
Dot = the Kalshi contract in the panel (15m). Every other tab charts the same 15-minute contract.

How to read this Ethereum 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 ether contract is worth, after the fee?
- To beat
The target Kalshi publishes when the quarter-hour window opens, quoted for ether in dollars and cents. It is set at the open and does not move. Read the market subtitle on Kalshi before you size: it says whether ether has to finish above that figure or at it or above.
- ETH now and the gap
The live Coinbase ETH-USD price and how far it sits above or below the target. Kalshi's ETH 15-minute contract settles on the CF Benchmarks real-time index for ether, and Coinbase is one of the exchanges inside that index, so the two track closely without ever being the same number. The gap is what you are really trading.
- Up and Down prices
Up is the Kalshi ask for YES on this ether 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.
Real contract. KXETH15M opens a fresh up-or-down ether window on every quarter hour and settles on the CF Benchmarks real-time index for ETH at the close. That one contract is what the right-hand panel reads on every chart tab.
Chart views. Longer ether candles drawn over the same 15-minute contract. Kalshi lists an hourly strike ladder for bitcoin; we have not confirmed one for ether, so this desk stays on the quarter-hour window and does not show an ETH hourly market we cannot verify.
Our layout. The final 5 minutes of the live ether window, shaded, with a countdown to when that phase starts.
Our layout. Two or three ether windows in a row. Each is a separate trade, and a window Kalshi has not opened yet has no published target, so the desk says so instead of guessing one.
Chart views. Short ether candles over the current contract. Three-minute candles divide the window into five bars exactly; two-minute candles do not, so the window edges fall inside a bar and the desk places the window box by time instead.
Also real contracts. KXBTC15M, KXSOL15M, KXXRP15M and KXDOGE15M run the same quarter-hour cadence, each settling on its own CF Benchmarks index. Bitcoin has its own page, the BTC 15-minute desk; SOL and XRP have their own desks too, and DOGE still switches in place from the coin row at the top of this one.
Fees on a 15-minute ether window
A coin flip needs a real edge
Most ether 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.
These are the arithmetic, not a quote from the live ETH 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 ether 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 published write-ups on these markets were written about the bitcoin version, and the same formula and the same fee schedule apply to the ether window: 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 an ether 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 ether 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 ether window every 15 minutes isn't a reason to trade every one
Fast markets reward slow rules. Ether gives you 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 ether 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 ether 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."
