Robinhood adds Big Brother to entertainment prediction markets
Robinhood has added entertainment event contracts tied to the reality show Big Brother, expanding its prediction market offerings beyond politics and sports. The contracts are offered by Robinhood Derivatives, a registered futures commission merchant and swap firm. The move follows Robinhood's broader push into event contracts, including more than 100 planned markets and no-account-required access for existing users.
Robinhood's vertical expansion into entertainment contracts tests whether event markets can sustain user engagement between major political and sports cycles. The Big Brother launch gives Robinhood a recurring content calendar that Kalshi and Polymarket lack, potentially driving sticky retail volume during low-event windows. For competitors, the risk is audience capture: Robinhood's existing user base needs no new account or onboarding friction, so trial costs approach zero.
If entertainment contracts retain traders who entered during election or World Cup peaks, Robinhood builds year-round habit where rivals see seasonal churn. Kalshi and Polymarket must match the content cadence or cede the off-cycle retail layer entirely. The first quarterly volume split between sports, politics, and entertainment will reveal whether this is additive share or just noise.
