U.S. chip and AI infrastructure names led a global selloff on November 5 as investors extended the post-midterm repricing: the Nasdaq fell more than two percent in early trading, Korea’s KOSPI dropped over five percent with a program-trading sidecar, and Qualcomm and Arm carried overnight guide shocks into the open—the binding force is capital clearing crowded AI capex multiples, and the episode can run weeks to quarters unless evidence shifts on permits, memory supply, or hyperscaler spend.
Headline indices mislead: the Dow and swaths of consumer and industrial names held up while semiconductors, neoclouds, and Asia memory absorbed the shock. Culled mapped the setup across the sweep, the ballot moratoriums, the power-and-software barbell, and Qualcomm’s memory tax—Thursday is those lines converging, plus a question of shelf life.
New York, Nov. 5 — Thursday’s tape is not a classic crash. AP described AI chip weakness dragging the Nasdaq while much of the rest of Wall Street still responded to individual earnings. By mid-morning Eastern time, the Nasdaq Composite was down on the order of two to two-and-a-half percent, the S&P 500 roughly one to one-and-a-half percent, and the Dow had erased Wednesday’s euphoria to trade slightly negative after opening higher. South Korea’s KOSPI fell more than five percent, with the exchange triggering a program-trading sidecar—a concentrated shock in the AI and memory complex, not a uniform exit from U.S. equities.
The mechanism is the one Culled has been tracing since the blue sweep repriced magnitude, local ballots restricted buildout, power and software barbelled on gridlock, and memory rationing hit Qualcomm and Arm after the bell. Capital is marking down pick-and-shovel AI—chips, neoclouds, merchant power, DC construction—while some hyperscalers (Amazon, Alphabet) even gained on the idea that slower greenfield build makes existing capacity more valuable. Reuters quoted UBS analysts warning that perhaps 30 percent of expected U.S. data-center capacity additions in 2028 could face pause risk. That is an option-value haircut, not an instant shutdown of Nvidia shipments.
What Thursday added
Three accelerants stacked on the election read:
Regulatory shelf risk. Democratic control of Congress from January plus Texas governor Gina Hinojosa’s win fed desk notes from Macquarie and Deutsche Bank that oversight and moratorium politics could slow megawatt projects—even as veto math limits sweeping federal bans.
Earnings translation. Qualcomm fell about nine percent as handset silicon dropped 26 percent; Arm slid near ten percent on a guide that beat consensus but not whispers. AMD and Intel joined the slide. Counterpoint-style shipment weakness ties phone units to the same DRAM squeeze starving handsets while HBM lines stay sold out.
Asia price discovery. SK hynix, Samsung, Kioxia, and Japanese test and tool names sold off sharply before U.S. cash opened, forcing Nasdaq futures lower. When Seoul triggers a sidecar, global quant books notice.
The market is moving from the promise of AI to the price of AI—Incline Investment Management’s Ted Parkhill told Reuters—without every AI ticker being fairly priced at once.
How long this can last
Treat the episode as a positioning and multiple clearing, not a single-day event. Useful buckets:
Days to a few weeks (volatility band). Fast money can keep rotating within the AI stack—out of CoreWeave-type neoclouds and Vistra-linked power, into Alphabet-type owners of cash flow—as long as headlines stay hot on Congressional hearings, Texas permits, and memory guides. Nasdaq can swing two percent intraday without resolving the trend. Culled’s falsifier from Wednesday still applies: if 10-year yields rebound and AI multiples stabilize together, the story was gridlock noise; if yields stay soft and chips keep leading declines, the margin read is regulation plus duration.
One to two earnings seasons (base case for the factor unwind). Crowded AI hardware was already correcting before ballots: Goldman Sachs’ broad AI basket had fallen about 15 percent in October and sat more than 24 percent below peak pre-election. Factor unwinds with that much air in them often need two rounds of hyperscaler and memory guidance—Microsoft, Meta, Amazon, Google, Micron, TSMC—before funds know whether capex is delayed, redirected, or merely repriced. That maps roughly to late 2026 through early 2027 reports, not a single November Friday.
Quarters (tail if policy matches fear). If STATE actors deliver credible construction pauses, megawatt caps, or safety regimes that bite 2027–2028 interconnection queues—not just committee rhetoric—the clearing extends. UBS’s 2028 capacity-at-risk figure is the right order of magnitude for that tail: physical build lags politics by 12–24 months, so equity pain can front-run bulldozers.
What usually does not end it quickly. A one-line “AI is still transformative” CEO quote, or a Fed hold without softer December hike odds, rarely reverses a crowded unwind. Neither does a green Dow on industrials while SOX stays red—that is rotation, not repair.
What would turn it around
Watch for evidence, not vibes. Culled groups turnaround triggers into four tests:
1. Capex credibility. Hyperscalers explicitly reaffirm 2026–2027 AI spend plans and suppliers (Lumentum, Coherent, TSMC) guide up without blaming permit slippage. A cut—or a shift from greenfield to retrofit-only—extends the clearing.
2. Regulatory narrowing. Congress proposes oversight that targets safety and disclosure without moratoriums that freeze ERCOT-scale projects. Texas and Ohio clarify timelines instead of stacking indefinite bans. Until then, STATE keeps supplying option value to the downside for neoclouds and utilities.
3. Memory and handset relief. DRAM spot easing or Qualcomm/Arm sequential handset growth without price hikes would show the memory rationing tax peaking. Without supply relief, phone silicon keeps missing even when data-center demand is “supply limited,” as Cristiano Amon argued.
4. Macro relief that hits the discount rate, not just oil headlines. Brent bouncing back toward $97 Thursday after Wednesday’s plunge on Iran peace talk shows how fast the inflation narrative whipsaws. A sustained Treasury rally with falling Fed hike odds—not gridlock alone—helps long-duration AI multiples. Vice President JD Vance tying the midterm loss to the Iran war adds geopolitical variance: de-escalation that sticks could cool energy and rates; failure would revive stagflation fear Culled mapped in October’s oil-and-AI squeeze.

Desk playbook
Do not flatten all AI exposure because the Nasdaq screen is red; do separate owners of cash flow and installed base from sellers of marginal megawatts and wafers. Do expect Asia to lead the next gap down or snapback. Do treat KOSPI sidecars and SOX breadth as better thermometers than SPX.
The selloff can pause any session on oversold bids—Wednesday’s Dow plus three percent proved politics can still spark relief. Sustainable turnaround needs at least one of the four triggers above to show up in numbers, not press releases. Until then, CAPITAL is still asking what the AI buildout costs and who pays—not whether transformers are coming someday.
