The empire's concentration play, assembled from pieces other threads carry singly: the $40B OpenAI-stake loan (21 lenders), the 10GW Ohio Stargate campus (the one Nvidia may guarantee $250-500B against), Arm's 87.1% pledged as loan collateral ($5B sought + a $20B margin loan with an unresolved Dec-25 deadline), the $2B Intel stake, a renewed $10B OpenAI-collateral loan. Everything Son owns now collateralizes everything else. Track: the loan stack's health vs the AI-credit repricing, any forced Arm monetization, Stargate milestones.
