Market Radar →Nvidia Rubin Ultra reportedly pushed back to 2028
jukan05 relays a TMTBreakout report that Nvidia's Rubin Ultra has been pushed back to 2028, expressing surprise at the delay to the next-generation product roadmap.
Wait, what? Rubin Ultra has been pushed back to 2028?
A multi-year slip in a flagship GPU roadmap would defer expected performance and revenue uplift, potentially softening the AI capex cadence that underpins semiconductor and memory demand.
Watch Confirm with Nvidia roadmap disclosures or supply-chain checks; an on-schedule Rubin Ultra launch would falsify the delay.
Source →@bubbleboi flags Saudi Aramco cancelling all September European crude allocations
@bubbleboi reacts to a report that Saudi Aramco cancelled all September European crude allocations and is scrapping every cargo slated for late-September loading onward, with a European lifter saying no Saudi cargoes at all until November, per Onyx and market sources — described as a de facto force majeure taking the world's largest exporter out of Europe for the rest of September and all of October.
Saudi Aramco has cancelled all of its September European crude oil allocations and is scrapping every cargo slated for late-September
Removing the largest exporter from a major demand region is a physical supply shock that pressures European crude differentials and product cracks higher, with knock-on effects for refiners and freight.
Watch Confirmation from Aramco, Onyx, or European refiners that November cargoes are also at risk, and whether Brent/Dubai spreads and European product cracks widen further.
Source →Nvidia's $279B purchase commitments against under 10 days of DRAM inventory
tengyanAI notes Nvidia's latest 10-Q shows $279B of purchase commitments, mostly memory, while Samsung and SK Hynix hold under 10 days of finished DRAM inventory per KB Securities, framing it as a shortage visible from both ends, with Micron reporting Sept 30 as the read-through.
meanwhile Samsung and SK Hynix are holding under 10 days of finished DRAM inventory (acc to KB Securities) one side
Locked-in multi-year buyer commitments against sellers who cannot build a buffer is the classic precondition for memory pricing power, which would flow directly into Micron's pricing line and margins.
Watch Micron's Sept 30 report: whether realized DRAM pricing and inventory days confirm the thin-buffer claim.
Source →20Y auction tails 2bp at record 5.42% yield, ending stellar-auction streak
Zero Hedge argues the streak of strong Treasury auctions ended with a 2.0bp tail to the 5.400% when-issued yield, the biggest tail since December 2024, and a 5.42% high yield that is the highest on record for the 20-year tenor.
20Y prices at 5.420%, 2.0bps tail to 5.400% WI, biggest tail since Dec 2024.
A record-high 20-year clearing yield with a meaningful tail signals deteriorating demand at the long end, pressuring duration-sensitive equities and housing via higher long-term borrowing costs.
Watch Whether the 20-year yield holds above 5.40% and whether the next long-end auction shows a smaller tail or stronger indirect participation.
Source →Meta's in-house Arke silicon targets Nvidia cost displacement from H1 2027
Meta reportedly plans to deploy new in-house Arke chips in the first half of 2027 and says the chips will save money and energy compared with Nvidia, with a next-generation Astrid chip slated for end-2027.
META to deploy new in-house Arke chips in first half of 2027.
A credible hyperscaler claim of cost/energy advantage versus Nvidia is a direct challenge to the assumption that merchant GPU demand is inelastic at the accelerator layer; it pressures the Nvidia attach-rate narrative even if volumes remain small.
Watch Whether Meta discloses Arke deployment volumes, whether Nvidia data-center revenue guidance or hyperscaler capex mix shifts, and whether Meta's own silicon replaces or merely supplements purchased GPUs.
