- Options — same-day and next-day calls and puts on the biggest US stocks and ETFs. Pick “Above X”, pay the premium, and get paid by how far the stock finishes past your strike at the 4:00 PM ET close.
- Interval markets — Up or Down on whether a stock or crypto price closes a 5-, 15-, or 60-minute window above where it opened. Every winning contract pays $1.00.
