Crypto: Polymarket, Kalshi Clash Over Groceries As Prediction Markets Boom

The grocery giveaways come as Kalshi and Polymarket lead prediction market trading volumes, which have recently exceeded $400 million per day.

Two leading prediction market platforms, Polymarket and Kalshi, have both turned to giving away groceries amid a fight for dominance in the fast-growing prediction markets space.

Kalshi offered a $50 grocery giveaway to over 1,000 people in Manhattan on Tuesday, while competitor Polymarket announced plans to open a free grocery store starting next week.

Kalshi and Polymarket have led the pack in prediction market trading volumes, which are now consistently above $400 million daily, representing about a fourfold increase from this time last year.

Kalshi banked $263.5 million from fee revenue alone in 2025, while both platforms have been marked at multibillion-dollar valuations on the back of major integrations.

The Kalshi promotion was offered at the Westside Market at 84 3rd Ave. in Manhattan between 12 pm and 3 pm local time on Tuesday, with videos on social media showing the lines stretching for multiple blocks.

According to Kalshi’s guest list, 1,795 people signed up to receive free groceries, while mainstream media reported that “thousands” attended.

Polymarket said on Tuesday that it signed a lease to open “New York’s first free grocery store” and donated $1 million to Food Bank for NYC to assist those with limited access to food across all five NY boroughs.
