SoftBank sheds 10% as the AI slowdown call hits the tape
The pacing debate spent Saturday as an argument between CEOs. Monday, it became a price.
The slowdown call produced its first global sell-off, and the damage spread across three continents. South Korea's SK Hynix closed down more than 6% and Samsung Electronics more than 4%, while SoftBank — one of OpenAI's largest backers — fell 10% in Tokyo. Europe continued the slide: ASML dropped more than 4%, Infineon more than 6%, Nokia around 5%, with data-center suppliers Siemens Energy and Schneider Electric also lower. In U.S. premarket trading, Intel fell nearly 6%, Micron around 5%, and Nvidia more than 2%. The trigger chain runs from Anthropic researcher Jacob Coxon's resignation over "gambling with our lives", through Dario Amodei's Saturday essay demanding the industry "slow the pace", to the rare public agreement from Sam Altman and Elon Musk — the first time the pacing camp spoke with one voice, and the first time markets priced it. RBC Brewin Dolphin's Zoe Gillespie put the fear plainly: the equity rally is built on AI growth and productivity gains, and if that derails, "we may see this destabilize." Earlier this morning the story was a Tokyo wobble with oil as an alibi — see Nikkei breaks 63,000 as the AI slowdown debate hits the market — but once Europe and U.S. futures joined with the same names falling, the read changed: investors now model "pace the frontier" as a valuation risk, not a safety footnote.
Beijing answered the slowdown call, and its answer was: keep us out of it. Foreign Ministry spokesperson Guo Jiakun said Monday that spreading "various threat narratives", confrontation and malicious competition only disrupt global AI governance and "serve the interests of neither side" — a direct rebuttal of the Amodei framing, and pointed given the essay cites China's computing scale as part of the race dynamic. The same weekend, Trump dismissed the pacing push in Ireland as hype from "very negative forces" and repeated that "whoever wins AI wins everything." The practical result: the two governments the slowdown debate is nominally about have both rejected it, leaving a voluntary pact among three American labs with no counterpart abroad and no constituency at home.
Nvidia put up a product page for an 84GB Blackwell card, and the local-inference crowd treated it as a release. The RTX PRO 5500 Blackwell Workstation Edition carries 84 GB of GDDR7 with ECC at a quoted 1,398 GB/s, 21,760 CUDA cores on the GB202 die, a 600 W power limit, MIG partitioning into one 84 GB or two isolated 42 GB instances, and PCIe 5.0 — sold for rack-mounted workstation fleets, with a liquid-cooled variant promised later and pricing undisclosed; Nvidia's page still says "Coming Soon". One caveat from the spec sheet: the listed 416-bit memory bus doesn't square with 84 GB at 1,398 GB/s, which arithmetically implies a 448-bit interface. For anyone running models locally, the capacity is the point — 84 GB fits a heavily quantized 100B-plus model, or two 42 GB tenants on MIG, on a single card roughly 12 GB below the flagship RTX PRO 6000.
What to watch: the U.S. open — whether the decline survives contact with Wall Street's dip-buyers, and whether the pacing camp floats anything concrete enough to trade against this week.
