OP17, The World's Strongest Warriors, is the One Piece Card Game's 4th anniversary main set, and the first one Bandai ships worldwide at the same time: August 26, 2026 in the UK and Europe and August 28, 2026 in the United States, following the Japanese release on August 22. One launch window, one global scramble for boxes.

This page is the Terminal's living hub for the set. We update it as reveals land and flip it to live market coverage the day prices exist.

The release, in brief

  • English release: August 28, 2026 (US), August 26 (UK and EU)
  • First main set with a simultaneous worldwide launch, so the usual JP-first price discovery window is gone
  • Anniversary set: expect anniversary chase treatments in the vein of the gold and silver classes that made OP11 and OP12 boxes what they are
  • Reveals are ongoing; the confirmed card list grows almost daily through August

What the anniversary label has meant for prices

Anniversary and milestone sets carry the heaviest chase classes Bandai prints, and the market prices sealed product accordingly. The pattern from recent sets: boxes command a premium at release, and the gap between a box's market price and its expected value is set by two or three cards at the top of the rarity ladder.

You can see that structure live on our box EV rankings, where every English set's expected rip value sits against its sealed price. Every box on that page is negative EV, which is what real booster boxes look like. The question for OP17 will not be whether it is positive, it will be how close to break-even the anniversary chases pull it.

Preordering: how we would read it

Preorder allocations for a worldwide simultaneous release are an open question, and scarcity stories move faster than facts in release month. Our approach stays the same as for any set:

  1. Watch the sealed market price against MSRP once listings stabilize
  2. Wait for our day-one EV computation before deciding to rip or hold
  3. Treat single-card price predictions before release as entertainment

The set pages for recent releases like OP15 and OP16 show how quickly release-week prices settle in the data.

What happens here on release day

The moment OP17 singles have market prices, the Terminal picks the set up automatically: a full card list with live prices on the set page, the box's EV verdict on the rankings, movers on the front page, and PSA population data as the first graded copies come back. This hub flips from preview to live coverage the same day.

The Terminal take

A worldwide simultaneous launch for an anniversary set is a genuinely new market setup for this game: no JP price discovery to lean on, one global demand spike, and anniversary chase classes on top. That is a recipe for a volatile first month. We will publish the numbers as they happen rather than guess at them now.
