Meta Tried to Buy Kalshi. Talks Broke Down. Now Zuckerberg Is Building His Own — With Play Money.
NPR reported on June 30 that Meta's Mark Zuckerberg held acquisition talks with Kalshi CEO Tarek Mansour last year, but negotiations never advanced — either because Mansour would not sell or because Meta found the legal and regulatory complexity too messy. Meta is now building its own prediction market app, called Arena, which will use play money only. Separately, Bernstein analysts named Kalshi and Polymarket as likely M&A targets for DraftKings, Robinhood, or Coinbase.
NPR reported on June 30 that Meta CEO Mark Zuckerberg personally met with Kalshi CEO Tarek Mansour last year to discuss a potential acquisition of the exchange. The talks did not progress. Two competing narratives explain why: one account says Mansour would not agree to a sale, having built Kalshi toward an independent IPO; another says Meta concluded that the legal and ethical questions surrounding a real-money prediction market — the CFTC litigation, the state-law exposure, the gambling-regulation entanglement — were too complex for a company already navigating its own regulatory environment. Both explanations may be accurate simultaneously. What followed was that Meta assembled an internal team to build a competing product from scratch.
That product is called Arena. Internal documents reviewed by NPR show an app that lets users make guesses about future events across news, sports, and trending topics — but using play money only, with no real-money wagering. The design choice separates Meta from Kalshi and Polymarket at the core product level: Arena is closer to a prediction-market game or social forecasting feature than to a regulated financial exchange. That trade-off avoids the CFTC licensing requirement, state gaming-law exposure, and the kind of operator liability that comes with settling real-money contracts — but it also means no revenue from trading fees and no pathway to the price-discovery function that makes prediction markets useful for hedging and information aggregation.
The Meta episode fits the broader M&A pattern that Bernstein analysts laid out in a June 29 note identifying Kalshi and Polymarket as likely acquisition targets. Bernstein's thesis: the two platforms own the exchange technology stack and have built regulated infrastructure, but they trail on consumer distribution compared to companies like Robinhood, Coinbase, and DraftKings, which have tens of millions of existing users. The report named all three as plausible acquirers. Robinhood and Coinbase are noted as particularly well-positioned because each already operates regulated financial infrastructure alongside large retail audiences — DraftKings has the sports-betting audience but would need to resolve jurisdictional overlap between its sportsbook licenses and a CFTC-regulated prediction market. The Bernstein note effectively describes the gap that Meta tried to fill by acquisition before opting to build.
The prediction-market sector is moving into a consolidation phase faster than most observers expected six months ago. The World Cup drove $44.8 billion in combined Kalshi and Polymarket volume in June — a 75% jump from May — and every major consumer-facing financial and betting platform is now either distributing prediction-market products (Robinhood, DraftKings, Wealthsimple) or building competing ones (Meta). The question the Bernstein note and the Meta story both raise is the same: in a sector where distribution determines winners more than technology does, which exchange survives independently long enough to go public, and which gets absorbed into a larger platform before an IPO window opens?

Pew Research: Prediction Market Volume Doubled May-July, Sports Now Largest Category
A Pew Research Center analysis published September 23 found that combined monthly trading volume on Kalshi and Polymarket more than doubled from May to July 2026 — rising from $26 billion in May to $53 billion in July — driven primarily by sports contracts. Sports is now the largest trading category on both platforms. During the FIFA World Cup in June and July, Kalshi's monthly sports volume reached $58 billion. Over the same period, Americans wagered roughly $40 billion at licensed sportsbooks — suggesting prediction market sports volume has approached or exceeded licensed sports betting in dollar terms.
Democrats Now 60% Senate, 90% House Favorites on Prediction Markets — Biggest Shift Since 2024
