US Market Recap: A Prospectus Lifts Chip Stocks, an Election Result Sinks Brazil

I. Indexes: five benchmarks up, in almost a mirror image of Friday

II. Sectors: seven up four down, a 2.92-point spread, the narrowest in a week

III. Semiconductors: all 30 constituents rose, yet October is still down 12.2%

The S-1 was able to lift the whole chain because it delivered auditable revenue rather than a narrative: 16.3 billion dollars in the first half, 11.6 billion in the second quarter alone, more than double all of 2025, and about 131 billion dollars of cash and equivalents on the balance sheet. DA Davidson's read is that the company is making money, which forces a correction to the assumption that both Anthropic and OpenAI were burning cash. The SOX rose 2.82% with all 30 constituents higher, its best day in about a month, but it is still down 12.2% in October, and Morgan Stanley warned the same day that semis could see another 10% to 15% of downside before bottoming in mid-November.

IV. Storage and optics: more than two points of dispersion inside one chain

If the total size of AI capex is being questioned, which link of the chain captures the money is a separate question. Monday's answer was storage and optical connectivity: the pricing and tight-supply thesis in memory was unchanged, while optical modules were repriced as an unavoidable part of compute expansion. Lumentum rose 8.19% and Coherent 5.83%, both among Reuters' top S&P 500 gainers; the whole optical chain moved from chips to components to systems, with AAOI +6.56%, Ciena +4.89%, Corning +3.27%, Fabrinet +3.27% and Arista +2.83%. SK Hynix had separate news: the Seoul Economic Daily reported the company is preparing 50 to 60 trillion won of additional shareholder returns, possibly including a special dividend and further buybacks, equal to roughly 35 to 42 billion dollars.

V. Big Tech: hardware up, platforms down

VI. Meta's $95 billion: AI capex starts being paid by shareholders

Meta's financing deserves its own section because it shifts the cost of AI capex from interest expense to equity. The company launched two concurrent underwritten offerings totaling about 35 billion dollars: 22.5 billion of Class A common stock executed through forward sale agreements, which deliver no initial proceeds, plus 12.5 billion of depositary receipts on mandatory convertible preferred stock. It also plans an at-the-market program of up to about 60 billion dollars once the Class C non-voting shares begin trading, a condition no earlier than the first quarter of 2027. Nvidia, AMD and Broadcom have indicated interest in subscribing to up to 5 billion dollars of the Class A shares in aggregate, non-binding.

Add the three pieces and the ceiling is roughly 95 billion dollars. Set that against the prior quarter: third-quarter capex of 34.9 billion dollars already exceeded operating cash flow of 32.8 billion, and free cash flow was negative 2.1 billion dollars, the first quarterly outflow since 2012. In other words, internal cash flow no longer covers the bill, so the funding has to come from equity. The stock fell 1.88%, not a large move, but it sits on the heaviest weight in communication services and dragged the sector to -1.42%.

The other compute financing of the day was a lease. SpaceX signed a roughly 40 billion dollar binding financing lease with entities managed by Apollo Global: the counterparties buy GPU clusters and related equipment and lease them back to SpaceX, with closing expected before year-end and the lease term starting when equipment is delivered in the first half of 2027. Musk also made a remark that traveled widely: debt markets are unwilling to finance companies whose revenue depends almost entirely on AI data centers, and more than two hundred neoclouds face consolidation and mass failure. SpaceX itself already carries 40 billion dollars of debt financing for Nvidia GPUs, but it also has Starlink and launch revenue.

VII. Brazil: Lula's reversal unwinds the Bolsonaro trade in one session

Sunday's second round delivered a reversal: President Lula defeated Flavio Bolsonaro, the right-wing candidate who had led the first round, and secured a fourth term. In the October 4 first round Bolsonaro led with 47.03% against Lula's 45.16%, and the market had broadly bet that a right-wing government would tighten fiscal policy, cut spending and bring rates down, which drove a sharp rally in Brazilian risk assets. Monday's selling was the other side of that position, concentrated in the banks, fintechs and utilities that had run the hardest.

XI. The week ahead and other events

• Wednesday: the Fed decision, with the market pricing only a 12.7% chance of a hike

  CME FedWatch puts the odds of a hike at this meeting at just 12.7%, with a hold as the consensus. The harder event is the press conference: Alphabet and Microsoft report the same afternoon, and strategists surveyed by Bloomberg expect attention to rotate wholesale from macro to those two prints after 4:30 pm on Wednesday.
• More than a third of the S&P 500 reports this week, 179 companies in all

  Alphabet, Microsoft and Amazon lead, and the four items the market is watching are cloud growth, AI-related revenue, data center capex and free cash flow. Those numbers will decide which side of the "AI capex is a credit or a cost" debate the Street sits on next month; Meta's swing to negative free cash flow already set one price.
• Thursday and Friday: third-quarter GDP, September PCE and the employment cost index

  Three releases at the tail of the same week, along with Monday's ISM and Friday's ECI, make up the last batch of hard data before the November meeting. With the 10-year pinned at 5.00%, this data matters more for the direction of rates than for growth.
• OpenAI releases GPT-6.1 Terra and halves API pricing

  Unlike previous launches, the emphasis here is price: API calls were cut by half. Read against the revenue growth disclosed in Anthropic's filing, competition among frontier labs has shifted from capability to unit cost, and falling costs eventually feed into the bargaining over compute purchases.
• Asia split: Korea down 1.46% while Hong Kong and the mainland rose

  The Hang Seng added 0.51% to 23,211.81, the Shanghai Composite 0.19% to 3,697.52, the Shenzhen Component fell 1.19% to 11,534.38, the Nikkei lost 0.80% to 62,189.65 and Korea's KOSPI fell 1.46% to 5,469.47. Taiwan was closed for an exchange holiday, so TSMC traded only through its ADR.

XII. Views

• A prospectus can rescue a day, not a month
  The SOX rose 2.82% with all 30 constituents higher, retaking less than half of the 6.72% drop from October 22, and it is still down 12.2% in October. Advancers outnumbered decliners by only 1.36 to 1, volume of 16.7 billion shares ran below the 20-day average of 17.2 billion, and the index gain was concentrated in a handful of names. Morgan Stanley said the same day that semis have another 10% to 15% of downside before bottoming in mid-November. Put together, Monday delivered a sentiment repair from a single document, not a change in the structure of flows. Confirmation would require volume back above its average first.
• Pricing power in AI financing has moved from debt to equity, and Meta is the first sample
  Meta's third-quarter capex of 34.9 billion dollars already exceeded operating cash flow of 32.8 billion, free cash flow was negative 2.1 billion, and it has now layered on an equity program with a 95 billion dollar ceiling, 60 billion of which cannot start until the Class C shares trade in the first quarter of 2027. Choosing equity over more debt implies debt pricing is no longer attractive. The cost is dilution, which is why the stock fell and dragged communication services to a fifth straight loss. Nvidia, AMD and Broadcom are willing to subscribe to as much as 5 billion dollars, which is both an investment and a prepayment on orders: chipmakers are now backstopping their customers' financing, something the last cycle never produced.
• The divergence between hardware and platforms is widening, not converging
  On a single day, the SOX was up 2.82% and technology 1.50%, while communication services fell 1.42%, Alphabet -1.06%, Meta -1.88% and Apple -1.10%. All four mega caps that rose are tied to compute supply; all three that fell are platforms. The same split appeared last Thursday in reverse, with hardware sold and platforms resilient. Two reversals within a week says money is being shuttled between two baskets without forming a new position structure. Which side holds will be settled by Alphabet's and Microsoft's capex commentary this week, not by the share prices themselves.
• Brazil is the year's cleanest case of policy being priced
  The first round had Bolsonaro at 47.03% and Lula at 45.16%, and the market bet that a right-wing government would tighten fiscal policy, which lifted Brazilian risk assets. The second round reversed it, and the same positions were unwound within a day: EWZ -19.82%, EWZS -31.60%, XP -48.34%. What matters is not the size of the losses but how far they spread: the S&P 500 rose 0.70% and financials added 0.21%, so this was a country allocation adjustment that never became an emerging-market systemic event. The lesson for next time is that trades betting on election outcomes lose far more than expected on settlement day, because liquidation and stop-losses arrive together.
• Three variables for the week, in order of importance
  First, the capex commentary from Alphabet and Microsoft, both on Wednesday afternoon: the market has already priced one warning via Meta's negative free cash flow, and these two numbers decide which way the line breaks. Second, Wednesday's decision and press conference, where a 12.7% hike probability means a hold is fully priced and a surprise can only come from language. Third, whether the 10-year holds 5.00%, which it did on Monday as the 2-year and 30-year each fell 1 to 2 basis points and the curve steepened slightly; if Thursday's GDP and PCE push the long end higher again, pressure returns to the expensive end of the market.
