Mark Zuckerberg has urged Meta's senior leadership to explore partnerships with Polymarket and Kalshi, according to a New York Times report cited by The Block on Friday, days after the paper revealed Meta was building its own competing prediction-market app codenamed Arena.
The new reporting adds a partnership track to a strategy that had previously been framed as a build-it-themselves effort. The Block reported the development Friday, citing the Times. The Times reported three days earlier that Zuckerberg ordered a small team to build Arena, a standalone prediction-market app to be kept separate from Facebook, Instagram and WhatsApp. The partnership exploration is framed as exploratory, per the reporting.
Meta would not be the first major social platform to integrate prediction markets. X named Polymarket as its official prediction-market partner in June 2025, embedding live market probabilities and Grok-powered annotations alongside posts. A Meta partnership would offer a substantially larger potential audience: Meta's Family of Apps reached 3.56 billion daily active people in Q1 2026, per the company's earnings report.
Polymarket and Kalshi have expanded rapidly over the past year. Combined event-contract trading volume crossed $60 billion in 2026, drawing institutional market makers including Wintermute as liquidity providers. Kalshi closed a $1 billion raise at a $22 billion valuation in May and is now targeting a $40 billion valuation in a new round, per reports this week.
