Funding & custody

The clearest difference is funding. Polymarket settles in USDC on a blockchain, so you connect a wallet and keep custody of your own funds, while OG funds in plain US dollars held by the platform — generally the simpler route for newcomers. If “connect a wallet” gives you pause, OG is the easier start.

Markets & coverage

On coverage, Polymarket leans toward politics, world events, crypto, whereas OG centres on sports outcomes & events. If your priority is liquidity & global events, Polymarket fits best; if it's sportsbook-style on-ramp, OG is the stronger home.

Ease of use
