Prediction market platform Polymarket announced the official opening of "The Polymarket," New York City's first free grocery store, at 137 South 7th Avenue. Built by New Yorkers and serving the city's residents, this new store comes amidst intensified competition between prediction market platforms Kalshi and Polymarket for new users. Kalshi launched an event on February 3rd at WestSide Market in Lower Manhattan, offering customers $50 worth of free groceries, attracting long lines and many participants who said it was equivalent to several hours' wages, making it very attractive. Kalshi co-founder Tarek Mansour stated that this move was to give back to the community and expand its user base. Polymarket, meanwhile, opened "The Polymarket," New York City's first free grocery store, with all items free, requiring no purchase, open to all New Yorkers, and an additional $1 million donation to local food banks.
