Robinhood prediction market fees (2026)

Affiliate pages still quote a flat $0.02/contract. That is stale. Robinhood switched to a probability-weighted commission on June 1, 2026.

Robinhood commission

Commission = k × p × (1 − p) × c

• k = 5% with Robinhood Gold, k = 10% without
• Commission rounded up, max $0.01/contract
• Plus exchange fee up to $0.01/contract (partner exchange on the contract)

Bot implication

Fees alone rarely decide automation. Without a public predictions API, Robinhood remains a retail UX — not bot plumbing. Join the Bot for Robinhood waitlist for product news.
