► HIP-4: Polymarket bettors vs. HL traders

#Hyperliquid bringing out HIP-4 to enter prediction markets isn’t as simple as trying to steal Polymarket / Kalshi users.
prediction markets today are already big, ~$27B volume in Jan 2026. but HL is doing ~$200B+ on the same month just on perps.
HL just needs to redirect its own flow, which is very different from the usual prediction market crowd.
the sophisticated leveraged traders who think in terms of delta, correlation, and cross-asset hedging finally has a home in HIP-4.
let me explain why this is actually a massive deal structurally.
every dollar on Polymarket or Kalshi sits in an isolated silo. you can’t cross-margin it. it doesn’t know anything about your other positions.
→ for a retail bettor, that’s fine
→ for a trader running a multi-million dollar derivatives book, that capital is dead
but on HIP-4, outcome contracts live natively on HyperCore, same matching engine and same margin account as perps.
which means the portfolio margin system can recognize that your long BTC perp and your binary YES on a rate cut are correlated exposures, and net the risk.
portfolio margin already delivers 30%+ efficiency gains over standard cross-margin on HL. add outcome contracts into the nettable universe and that compounds further.
that’s capital efficiency that doesn’t exist anywhere else in prediction markets today.
imo, the HIP-4 user base is already there, ~231K weekly active traders, and they trade way bigger size than Polymarket / Kalshi bettors.
might even pull in users who are restricted from those platforms due to regulation.
we’re probably about to see another surprise in HIP-4 volume once perp traders start betting with size.
then you know what happens next. HL generates more revenue → more flow into $HYPE buybacks.
still early to say HL will beat both giants, but the game might flip entirely once HIP-4 hits mainnet.
