Election and nomination markets are the deepest contracts either venue runs, and the 2028 nomination books alone have traded well over a billion dollars on Polymarket. Depth does not mean agreement: the nomination favourites regularly sit several points apart across the two venues, because each book has its own participants reacting to the same news at different speeds.
Political contracts also carry the most regulatory attention. Several states have challenged event contracts on elections — the current position is covered in our legal guide.
Frequently asked questions

Can I bet on the 2028 election on Kalshi?
Yes — Kalshi lists both nomination markets and party-level presidential contracts, and is available in most states. Coverage by state has been contested and keeps changing; see our legal guide.
