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?

Massachusetts Supreme Court Ruling on Kalshi Now Imminent — First State High Court Decision on Prediction Markets
The Massachusetts Supreme Judicial Court heard oral arguments on May 5 in the Kalshi prediction markets case and is expected to issue a decision within weeks. The SJC appeared skeptical of Kalshi's argument that CFTC regulation preempts state gambling law, and the court's ruling will be the first state supreme court decision on prediction markets anywhere in the country. Massachusetts AG Andrea Campbell secured a preliminary injunction blocking Kalshi's sports contracts in January 2026. The CFTC filed an amicus brief supporting Kalshi; a coalition of 38 state attorneys general filed an opposing brief supporting Massachusetts.
27 States Back California Tribes Suing Kalshi Over Sports Contracts Under Indian Gaming Law
Three California tribes — Blue Lake Rancheria, Chicken Ranch Rancheria of Me-Wuk Indians, and Picayune Rancheria of the Chukchansi Indians — are separately challenging Kalshi's sports event contracts in the Ninth Circuit under the Indian Gaming Regulatory Act, a federal law distinct from the Commodity Exchange Act preemption arguments at issue in Nevada, New Jersey, and Connecticut. The Ninth Circuit refused to consolidate the tribal case with the Nevada case. A Ninth Circuit panel appeared skeptical of Kalshi in July hearings, and 27 states plus the District of Columbia have filed amicus briefs supporting the tribes. The IGRA theory, if it succeeds, could block Kalshi from operating sports contracts in any state where tribal gaming compacts exist — a category that includes most US states.
SCOTUS Review of Prediction Markets Hits 64% on Polymarket — New Jersey Files Cert Petition September 3
The probability of Supreme Court review of prediction market sports contracts jumped from around 30% to 64% on Polymarket's own platform within hours of the Ninth Circuit's August 28 ruling — with $976,000 in trading volume flowing into the contract. New Jersey, the losing party in the Third Circuit's April ruling that went for Kalshi, is filing a certiorari petition on September 3. The Ninth Circuit's 3-0 ruling against Kalshi directly contradicts the Third Circuit's 2-1 ruling for Kalshi, creating the clearest possible circuit split trigger for SCOTUS to grant review.
