$ARB arb was on the radar 68 hours ago ripping 14% on 8x volume. today it's back with a fresh leg, up 29% now, and this time the tape actually has a reason: standard chartered slapped a bullish long term call on it and robinhood chain running on arbitrum is generating real revenue for the ecosystem.

funding's still priced for the old, quieter arb. shorts sitting on stale bets are getting run over while spot volume runs 4x normal.

smart money's been net selling arb the past week too, small size but the wrong direction for this move.

so which is it, catalyst driven repricing that's just getting started, or shorts about to get flushed into a wall smart money already walked away from?
