Nvidia and Amkor target a more than 300% interposer capacity increase by 2028, Nvidia and SPIL will expand optical-engine capacity in Taiwan, and Samsung Electro-Mechanics and Nvidia reported a pact on ABF substrate. @FinnStockinger put the scaling at 2.5x substrate, 4x+ advanced packaging and 15x CPO optical-engine capacity.

Nebius CRO Marc Boroditsky said 1 GW of Vera Rubin capacity is coming next year and that Nebius lacks capacity for customers' late-2027 and early-2028 needs, per posts quoting him. On the credit side, @burggrabenh said Oracle's 5-year CDS implies a 24% cumulative default probability.
