$ARB is up roughly 90% in three weeks.

Now the timing gets interesting.

It's biggest unlock of the year — 92.6M ARB, somewhere around $12–13M — lands on September 16, right in the middle of this rally.

Most people will treat that as just another unlock.

I don't.

ARB's recent move has been closely tied to Robinhood Chain fee revenue flowing back to the DAO treasury. But there's another detail worth watching: Robinhood's 90-day gas subsidy expires on September 29.

So two things are happening almost back-to-back:

Fresh ARB supply arrives.

Then the subsidy supporting the fee activity disappears.

That sets up a much cleaner test of the narrative.

If Robinhood Chain fees hold up once gas is no longer heavily subsidized, the story looks more durable.

If they drop sharply, it suggests part of this rally was built on a temporary boost.

I'm not watching the unlock in isolation.

I'm watching what happens to the fees after the subsidy ends.

That's where the real ARB story gets tested.
