Grocery store shelves are already stocked with candy corn, pumpkin-shaped chocolates and bagged Halloween candy, months before a single porch light gets a jack-o’-lantern glow. Shoppers aren’t waiting for autumn anymore, and retailers know it.
There’s a name for this now: “Summerween,” the practice of celebrating Halloween in the middle of summer instead of waiting for October. Costumes show up at big-box stores in July, and spooky home decor fills social feeds long before Labor Day. What used to be a tight sprint toward Oct. 31 now runs for months, starting practically the moment summer begins.
A new report puts a number on it
Mars just released its 2026 Tricks, Treats and Trends report to kick off the 100-day countdown to Halloween, and the timing lines up with what shelves have been showing for weeks. Surveying more than 3,000 U.S. adults, the report found that 57% now say Halloween isn’t a single day anymore but a full season, a belief strong enough that retailers are stocking accordingly instead of waiting for fall.
This kind of early creep isn’t new
Shoppers have complained for years about holiday creep, watching Christmas trees appear in stores before Halloween candy even clears the shelves. Halloween is now doing the same thing to itself, arriving earlier every year instead of waiting to be nudged out by the next holiday.
About 66% of U.S. adults said they would buy their favorite Halloween candy year-round if they could, and Gen Z is driving that interest hardest. Nearly 60% of Gen Z is aware of or has already participated in Summerween, roughly double the rate of the general population, with early activities ranging from baking spooky treats to hosting themed parties to decorating homes months ahead of schedule.
The data behind the candy bowl
Social media is doing a lot of the legwork before anyone opens their wallet. More than half of Gen Z discovers new Halloween candy trends on TikTok, while YouTube and Instagram trail close behind. Despite all that scrolling, the purchase itself still happens the old-fashioned way, in person at big-box stores and grocery chains rather than online.
The candy bowl, meanwhile, has turned into something close to a personality statement:
- Roughly three-quarters of U.S. adults believe a shared bowl builds community.
- 71% think the candy someone hands out says something about them as a host.
- 72% call handing out full-size bars the move that makes a house the unofficial favorite on the block.
- Chocolate still tops the list nationally, though the West leans hardest into Halloween-themed treats and the South gravitates toward gummies.
New products are already rolling out to meet the demand, including TWIX Skulls, SNICKERS Pumpkins and SKITTLES POP’D Creepy Crunch, alongside returning names like M&M’S Halloween Blend, which ranked as the top Halloween candy brand in the survey.
None of this requires anyone to build a full graveyard display in July. But if candy corn is already showing up in shopping carts, that’s not early. That’s just further ahead of a curve that keeps arriving sooner every year.
