What Robinhood and Kalshi actually are

Robinhood is a retail brokerage known for stocks and options; it has experimented with event-like products but is not primarily an event-market CLOB. Kalshi is a regulated exchange that lists binary event contracts under CFTC oversight. Both serve retail traders but operate under different regulatory and product models than Polymarket’s on-chain markets, settlement in pUSD, and UMA-based resolution.

Where Polymarket differs

Polymarket runs a Central Limit Order Book on Polygon with outcome tokens implemented via the Gnosis CTF and resolutions reported through UMA. Trading uses pUSD and is gasless for end users via the Polymarket Relayer. That design produces continuous order books for binary and multi-outcome markets, which is where intra-market arbitrage strategies can extract predictable edges when mispricing occurs.

How PolyArb fits your workflow

PolyArb automates intra-market arbitrage opportunities on Polymarket. It’s non-custodial, live today, and built for speed: 40ms latency vs ~800ms for common free bots.

When to prefer each platform

Use Robinhood for traditional equities and options. Use Kalshi if you need a CFTC-regulated exchange for certain event contracts.
