Meta Tried to Buy Kalshi. Talks Broke Down. Now Zuckerberg Is Building His Own — With Play Money.
NPR reported on 30 June that Meta's Mark Zuckerberg held acquisition talks with Kalshi CEO Tarek Mansour last year, but negotiations never advanced. Meta is now building its own prediction market app called Arena, which will use play money only. Separately, Bernstein named Kalshi and Polymarket as likely M&A targets for DraftKings, Robinhood, or Coinbase.
NPR reported on 30 June that Meta CEO Mark Zuckerberg personally met with Kalshi CEO Tarek Mansour last year to discuss an acquisition of the exchange. The talks did not progress. Two accounts explain why: Mansour would not agree to a sale, having built Kalshi toward an independent IPO; or Meta concluded that the legal and regulatory complexity surrounding a real-money prediction market — CFTC litigation, state-law exposure, gambling-regulation entanglement — was too messy for a company already navigating its own regulatory environment. Both may be accurate simultaneously. What followed was that Meta assembled an internal team to build a competing product.
That product is called Arena. Internal documents reviewed by NPR show an app for making guesses about future events across news, sports, and trending topics — 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 a prediction-market game rather than a regulated financial exchange. That avoids CFTC licensing, state gaming-law exposure, and the operator liability that comes with settling real-money contracts — but also means no trading-fee revenue and no pathway to the price-discovery function that gives prediction markets their financial legitimacy.
The Meta episode fits the M&A picture that Bernstein analysts laid out in a 29 June note identifying Kalshi and Polymarket as acquisition targets. Bernstein's thesis: the two platforms own the exchange technology stack and regulated infrastructure, but they trail on consumer distribution compared to Robinhood, Coinbase, and DraftKings. Robinhood and Coinbase are named as best-positioned: each operates regulated financial infrastructure alongside large retail audiences. DraftKings has the sports audience but would need to navigate overlap between its sportsbook licences and a CFTC-regulated prediction market. The Bernstein note describes the gap Meta tried to fill by acquisition before choosing to build.
The sector is consolidating faster than expected. Combined Kalshi and Polymarket volume hit $44.8 billion in June — up 75% on May — and every major consumer-facing financial and betting platform is now either distributing prediction-market products (Robinhood via Kalshi, Wealthsimple in Canada) or building competing ones (Meta). For UK observers, the strategic question is whether this consolidation pattern eventually forces the hand of UK-based operators — Flutter, Entain, bet365 — to either lobby for a regulatory pathway to prediction markets or watch the product category become a US-only competitor for global trading interest.

Massachusetts Supreme Court Ruling on Kalshi Now Imminent — First State High Court Decision on Prediction Markets
The Massachusetts Supreme Judicial Court is expected to rule within weeks on whether Kalshi's sports event contracts constitute illegal sports gambling under state law — the first time any US state supreme court has decided this question. The SJC appeared skeptical of Kalshi's CFTC-preemption argument at May 5 oral arguments. A coalition of 38 state attorneys general backed Massachusetts; the CFTC backed Kalshi. The outcome will be the first state apex court ruling on prediction markets anywhere in the country.
27 States Back California Tribes Suing Kalshi Over Sports Contracts Under Indian Gaming Law
Three California tribes are pursuing a separate Ninth Circuit case against Kalshi's sports contracts under the Indian Gaming Regulatory Act — a 1988 federal law governing tribal gaming rights that is independent of the CEA preemption arguments in the Nevada, NJ, and Connecticut cases. The Ninth Circuit refused consolidation with the Nevada case. A panel appeared skeptical of Kalshi in July. 27 states plus DC filed amicus supporting the tribes.
