Meta Explores Prediction Market Arena After Kalshi Deal Fails
1 Jul
Summary
- Meta CEO Mark Zuckerberg considered buying Kalshi, a leading prediction market.
- Negotiations between Meta and Kalshi reportedly stalled last year.
- Meta is now developing its own prediction market app called Arena.

Meta CEO Mark Zuckerberg explored acquiring Kalshi, a leader in the prediction market sector, last year. Negotiations with Kalshi CEO Tarek Mansour did not advance, with conflicting reasons cited for the breakdown, including Mansour's reluctance to sell and Meta's concerns over legal and ethical issues.
Despite the failed acquisition talks, Meta is pressing forward with its own prediction market app, internally codenamed Arena. This new platform will enable users to speculate on future events using virtual currency, with Meta's AI systems determining outcomes based on real-world occurrences.
Prediction markets have experienced significant growth, with combined monthly trading volume on Kalshi and Polymarket surging to nearly $220 billion by June 2026. Kalshi was valued at $22 billion in May 2026, while Polymarket is valued at $10.7 billion.
This pursuit of prediction markets aligns with Meta's established strategy of acquiring or replicating successful emerging platforms, such as Instagram and WhatsApp. However, this approach has drawn scrutiny from regulators, with the FTC alleging a 'buy or bury' tactic, although a judge previously ruled in Meta's favor regarding competition laws.
