BTCK8 expiry: May 26, 2028

When BTCK8 stops trading

Trading terminates at 4:00 p.m. London time on the last Friday of the contract month. For BTCK8 that falls on May 26, 2028.

Senzoukria stops offering BTCK8 as the default contract on May 22, 2028, 4 calendar days before that last trading day, and keeps it selectable with a badge. The date is computed from the exchange rule rather than stored. The engine counts Monday to Friday and holds no CME holiday table, so a date that falls next to a public holiday can be one day off the exchange calendar. Check the exchange calendar when the date sits close to a holiday.

When the volume actually leaves

Crypto futures at CME expire monthly and settle against a reference rate rather than a physical asset. Liquidity concentrates in the front month and thins quickly once the roll has passed.

For BTCK8 the next listed delivery is BTCM8, whose last trading day is June 30, 2028. That is the contract the volume moves into, just as it moved out of BTCJ8 on April 24, 2028.

What one tick is worth on BTCK8

The minimum price fluctuation is 5, which is $25.00 per contract on a multiplier of 5. A full point is therefore $5.00. On a footprint chart one row is one tick, so the same vertical space holds a different number of rows depending on the product: a tick of 5 sets how finely the bid and ask volume of BTC can be read.

These are the values the app itself trades on, taken from its contract table rather than retyped, so the P&L shown on a BTCK8 position and the rows of its footprint come from the same numbers.

Every BTC delivery listed in 2028

BTC lists 12 delivery months a year (F, G, H, J, K, M, N, Q, U, V, X, Z). BTCK8 is number 5 of 12 in 2028.

BTCK8 and MBTK8 side by side

BTC and MBT track the same underlying, but BTC is 50 times the size of MBT: $25.00 a tick against $0.50. Both quote on the same 5 tick. BTCK8 and MBTK8 share the same last trading day, May 26, 2028, so a position in either rolls on the same date.

The practical difference is position sizing rather than behaviour. MBT lets a 50-contract position carry the same exposure as one BTC, which makes partial exits possible on a small account; BTC carries the deeper book, so its footprint and its depth of market are the ones to read even when the position is held in MBT.
