⚠️ $8.3T in options expiring TODAY — biggest expiry in history.

Fundamentals don't matter for the next few hours. This is pure derivative machinery.

Here's what's actually happening:

Market makers who sold these options have been hedging by buying/selling the underlying stocks. When contracts expire all at once, they unwind those hedges simultaneously. That creates massive volume spikes and violent price swings, especially into the close.

This isn't just any expiry. It's 18% bigger than December's record ($7.1T). And it's hitting while:

- $SPX already down after Fed signaled potential rate hike before year-end

- Pension funds rebalancing end of Q1

- Positioning getting reshuffled across the board

Scott Rubner from Citadel says flows will dominate fundamentals for the next two weeks.

So is this just technical noise that clears next week, or the catalyst for a deeper correction?

Watch the tape closely today.
