What leaked

Early listings for the next mainline booster, THE DOMINANCE OF GOD, point to a November arrival. The set carries the OP18 code, and the leak names a Franky leader alongside a Nico Robin manga-art card as the early headline pulls.

That is the entire verified surface right now: a leader, a manga rare, a month. No confirmed rarity spread, no print structure, no box configuration. Which means our OP18 page is exactly what you would expect it to be at this stage.

The OP18 page is empty, and that matters

As of 2026-08-23, OP18 carries no box market price, no expected value, and therefore no EV ratio. There is nothing to model. Anyone quoting a chase-card figure for a set that has not been officially revealed is quoting a vibe, not a print.

What we can do is anchor expectations against sets that already trade. Here is the current box EV board:

Set Box market Box EV EV ratio
OP17 $410.62 $655 1.59
OP15 $253.35 $202 0.80
OP14 $264.28 $189 0.71
OP11 $632.38 $437 0.69
PRB02 $393.01 $264 0.67

OP17 is the outlier at a 1.59 ratio, and it is also the set doing the most violent price discovery. Everything else sits between 0.67 and 0.80, which is the normal gravity of a booster box once singles settle. Full board at the EV tracker.

The recent-set warning label

If you want a preview of what OP18 singles will feel like in month two, look at the freshest set on the board. Monkey.D.Luffy (079) (Alternate Art) from OP17 is the week's worst performer at $161.16, down 44.4 percent over seven days. That is what an unsettled chase card does when supply catches sentiment.

The rest of the drawdown list is promo-heavy: Sabo (120) (English Version 3rd Anniversary Set) at $73.46, off 39.8 percent, and Portgas.D.Ace (119) (English Version 3rd Anniversary Set) at $72.01, off 33.8 percent. Tony Tony.Chopper (Gift Collection 2023) is flagged as a seaking-severity move at $183.83, down 30.5 percent.

Where money actually went this week

The upside was concentrated in older paper. Jinbe leads the gainers at $31.25, up 58.1 percent, also tagged seaking. Sabo (004) (Alternate Art) is at $47.03, up 55.8 percent. Gold DON cards ran too: DON!! Card (Donquixote Doflamingo) (Gold) at $183.49, up 23.4 percent, and DON!! Card (Sabo) (Gold) at $122.54, up 20.9 percent.

One small irony for a set leaking a Robin manga card: Nico Robin from the ST01 preconstructed line is down 29.9 percent to $24.99 this week. Character demand and card demand are not the same instrument.

The Terminal take

OP18 has a name, a month, and two leaked cards, and zero rows in our pricing tables. The useful comparison is OP17, where a 1.59 EV ratio on a $410.62 box sits next to a chase alt-art that shed 44.4 percent in seven days. New-set EV is loud early and quiet later, and OP18 will get its first honest print only when boxes crack.
