Doorman waits in line for hours as NYC's 'first free grocery store' opens for 4 day pop-up. How it works — and what it reveals about rising food costs

Branded The Polymarket, the pop-up is open to the public for four days, offering staples like milk, eggs, bread and produce alongside familiar brand-name snacks — no payment required, no income verification and no purchase limit.

Polymarket is a company that allows users to wager on the likelihood of future events, from elections and economic data to sports championships and geopolitical outcomes, using cryptocurrency. The platform has drawn attention for enabling large payouts tied to real-world crises, even as supporters argue it offers a novel way to aggregate public sentiment.

According to an announcement published on the company’s Substack, the opening coincided with a $1 million donation to Food Bank For NYC, which serves food-insecure households across all five boroughs (1).

“We're open to all New Yorkers. A real, physical investment in our community,” the announcement reads. “Free groceries. Free markets. Built for the people who power New York. We'll see you at The Polymarket's grand opening next week. We love you, New York City.”

Why shoppers were drawn

For Thaddeus Romero, a Brooklyn resident who works nights as a doorman and concierge, the draw was practical. He arrived shortly after 10 a.m., hoping to get a decent place in line after finishing his shift the night before.

“Every crazy idea always makes good music,” Romero told Moneywise as he waited. By mid-afternoon, with the line still stretching down the block, he described the scene as calm and orderly.

Romero was most interested in the meat options. “You go to the grocery store right now, some of the meats are very expensive,” he said, pointing to how widely prices can vary depending on where you shop. At certain stores, he noted, a ribeye can still cost between $10 and $14, but finding it at that price isn’t guaranteed.

Those costs reflect a broader strain many New Yorkers are already feeling. The average U.S. household spends about $504 a month on groceries, according to Bureau of Labor Statistics data (2). In New York City, grocery prices surged 65.8% between 2012 and 2023, according to a report released last year by the New York State Comptroller’s Office (3).

Romero said the most he’s spent on a grocery trip was about $120. While he prefers to buy chicken, beef, T-bone steaks and ribeye, he tries to keep his weekly grocery bill under $100, typically landing closer to $90. Living alone, he shops with the goal of stretching that spend across the week.

"They had really good chicken breast in there. I picked up some ground beef and, surprisingly, bison meat," he added.

Why a free grocery store now?

The pop-up followed a similar move by rival prediction market Kalshi, which hosted a $50 grocery giveaway for East Village shoppers earlier this month (4). But the timing also taps into a much bigger conversation unfolding across New York City: how expensive food has become, and who, exactly, should be responsible for making it more affordable.

Mayor Zohran Mamdani has floated a proposal to open city-run grocery stores in every borough, selling food at wholesale prices. The idea has split affordability advocates and industry groups, sparking debate over whether public grocery stores would meaningfully lower costs or disrupt private markets.

Mamdani appeared to acknowledge that tension, responding to Polymarket’s free-store announcement on X (5). He posted a screenshot of a deadpan headline that read: “Heartbreaking: The worst person you know just made a great point.”

Inside the store, however, there was little visible reference to Polymarket’s core business. No betting prompts appeared alongside the shelves of free food.
