Financial News October 26, 2026: Brazil Markets Crash as AI Stocks Rally

Brazilian stocks and the real suffered historic losses Monday after President Luiz Inácio Lula da Silva won reelection, while Wall Street rallied behind Anthropic’s IPO filing and renewed demand for artificial-intelligence shares. Oil eased but remained above $116 a barrel as investors prepared for the Federal Reserve and a crowded earnings calendar.

Market information is current as of approximately 3 p.m. Eastern on Monday, October 26, 2026. Sunday’s election result and Friday’s U.S. market closes are completed. Monday’s European session is completed, while U.S., Brazilian, bond, commodity, currency and cryptocurrency markets remained in progress unless a settlement is specifically identified.

Global financial markets split sharply Monday. U.S. technology shares climbed as investors welcomed Anthropic’s long-awaited public filing, but Brazil experienced one of its most violent market reactions in decades after Lula’s unexpected victory over right-wing challenger Flavio Bolsonaro.

The contrast captured the central market debate. Investors remain willing to finance the artificial-intelligence boom, even as its costs rise, but they are demanding immediate evidence of fiscal discipline from governments confronting expensive debt and inflation.

Brazil Stocks Trigger Circuit Breaker After Lula Victory

Brazil’s benchmark Bovespa index fell more than 15% Monday, its largest daily percentage decline since 1998, after Lula secured a fourth non-consecutive presidential term. The exchange halted trading for 30 minutes when the index dropped 10%, activating its circuit-breaker mechanism.

The Brazilian real initially plunged more than 11% against the U.S. dollar, passing 5.6 per dollar at its weakest point. It later recovered part of the decline and traded about 8.3% lower near 5.4274 per dollar.

Government debt also sold off. Brazil’s dollar bond maturing in 2054 dropped approximately 2.5 cents, lifting its yield to 7.45%. Five-year credit-default swaps rose to 151.67 basis points from 120.21 Friday, signaling a higher perceived risk of sovereign distress.

The Brazilian Treasury canceled auctions of inflation-linked and fixed-rate bonds scheduled for October 27 and October 29. Raw sugar futures fell 5.6% because the weaker real can encourage Brazilian exporters to sell more dollar-denominated commodities.

Reuters reported Monday’s historic losses across Brazilian stocks, currency and sovereign debt.

Election Result Reverses a Month of Market Bets

Markets had positioned for a Bolsonaro victory after he unexpectedly finished first in the opening round. The Bovespa entered Friday almost 7% above its level before that vote, while the real had gained nearly 5%.

Investors expected Bolsonaro to pursue spending restraint, deregulation and closer commercial ties with the United States. Lula instead won 51.8% of the runoff vote, defeating Bolsonaro by more than 4 million votes.

Bolsonaro refused to concede and said he would seek an annulment, adding political uncertainty to the fiscal concerns. Investors are now focused on Lula’s choice of finance minister and whether his administration can slow public-debt growth while protecting social programs, wages and investment.

Lula’s team has said it wants to produce a budget surplus equal to approximately 1.3% of gross domestic product by 2030. Markets are demanding a detailed plan capable of making that target credible. Reuters documented the completed election result and Bolsonaro’s challenge.

Wall Street Rallies on Anthropic IPO Filing

U.S. stocks moved in the opposite direction. At approximately 3 p.m. Eastern, the Dow Jones Industrial Average was up about 0.2% near 52,333. The S&P 500 gained roughly 0.8% to 7,682, while the Nasdaq Composite advanced approximately 1% to 26,221.

Anthropic’s IPO filing revived interest in AI companies after two consecutive weekly declines for the S&P 500 and Nasdaq. The Philadelphia Semiconductor Index rose more than 3%, although it remained down nearly 12% for October.

Lumentum gained approximately 10%, Coherent rose about 7%, and Tesla climbed more than 6% to a three-month high after Barclays upgraded the electric-vehicle maker to overweight. Technology led the S&P 500 sectors with a gain of about 1.6%.

Reuters tracked Monday’s intraday Wall Street rally and AI-linked stock movements.

Anthropic Filing Reveals Rapid Growth and Extraordinary Costs

Anthropic’s filing showed why the potential offering is both appealing and risky. Revenue increased from $386 million in 2024 to $4.59 billion in 2025, then reached $16.29 billion during the first half of 2026.

The Claude developer posted an operating loss of $8.06 billion in 2025, although that measure narrowed to $693 million during the first half of 2026. Its reported net loss exceeded $80 billion because of a non-operating accounting adjustment tied to convertible bonds.

Anthropic has committed more than $500 billion of spending with six partners over a decade. Amazon, Google and Microsoft are simultaneously investors, suppliers and commercial partners, demonstrating how tightly connected AI financing has become.

Reuters analyzed Anthropic’s growth, losses, governance and long-term infrastructure commitments.

Meta Plans Record $95 Billion Equity Raise

Meta Platforms said it could raise as much as $95 billion to finance data centers, chips and other AI infrastructure. The plan includes approximately $35 billion in common and preferred offerings, followed by an at-the-market sale of as much as $60 billion after new non-voting Class C shares begin trading.

The fundraising underscores how the AI buildout is changing Silicon Valley finance. Meta generated negative free cash flow of $2.12 billion in the third quarter, compared with positive free cash flow of $10.63 billion one year earlier. It recently lifted its 2026 capital-spending outlook to between $135 billion and $145 billion.

Nvidia, Advanced Micro Devices and Broadcom have expressed interest in investing as much as $5 billion collectively. That possibility may deepen questions about circular financing, in which chip suppliers invest in the companies purchasing their products. Meta shares slipped about 0.4% Monday despite the broader technology rally. Reuters reported Meta’s proposed equity financing.

Oil Eases but Remains Near Six-Month High

Brent crude fell 0.6% to approximately $116.01 a barrel Monday, while West Texas Intermediate declined about 1.3% to $101.96. The retreat followed Friday’s completed settlements of $116.72 for Brent and $103.27 for WTI.

Hopes for renewed mediation between the United States and Iran reduced part of the geopolitical premium. Qatari mediators traveled to Tehran Sunday, and Saudi Arabia, Turkey and Pakistan were also preparing talks with Iranian officials.

The physical threat has not disappeared. Yemen’s Houthis said Monday that they attacked Saudi Arabia’s East-West crude-pipeline pumping stations and Riyadh airport. Continued attacks on Saudi infrastructure and shipping routes leave oil vulnerable to another sudden increase.

Treasury Yield Slips Below 5% Ahead of Fed

The benchmark 10-year Treasury yield eased to approximately 4.982% Monday. The Federal Reserve is widely expected to leave its target rate unchanged Wednesday after increasing it in September.

Futures markets placed the probability of an immediate increase at approximately 13%, but indicated an 80% chance of another quarter-point move in December. Thursday’s personal-consumption-expenditures report is expected to show core inflation of approximately 3.1% in September, while third-quarter economic growth is forecast near a 3.2% annualized rate.

The European Central Bank and Bank of Japan are also expected to hold rates this week. The Reserve Bank of New Zealand is widely expected to increase its rate, while investors are also watching the Bank of Canada.

Dollar Gains; Gold Reclaims $4,000

The U.S. Dollar Index gained approximately 0.25%. The Japanese yen weakened 0.36%, the euro declined 0.13% and sterling slipped 0.16% before Britain’s Wednesday budget announcement.

The Brazilian real was the overwhelming outlier, falling more than 11% at its weakest point as investors unwound election positions.

Gold recovered from Friday’s three-month low. Spot bullion rose about 0.6% to $4,020.60 an ounce, while December U.S. gold futures settled 0.8% higher at $4,038.40. Silver gained 0.4% to $54.11; platinum declined 1.1% to $1,533.65; and palladium rose 0.5% to $1,049.09.

Reuters reported Monday’s completed gold-futures settlement and precious-metals prices.

European Stocks Close Higher; Asia Slips

Europe’s STOXX 600 completed Monday’s session 0.77% higher, supported by corporate gains including British technology-services company Computacenter and Danish biotechnology company Genmab.

MSCI’s Asia-Pacific index excluding Japan closed 0.15% lower. Emerging-market stocks fell approximately 1%, with the Brazilian shock overwhelming otherwise constructive risk sentiment.

Bitcoin Holds Near $80,000

Bitcoin traded near $80,300 Monday, little changed from Sunday morning. Ethereum was near $2,327. Digital assets remained caught between improving technology-stock sentiment and tighter financial conditions generated by high interest rates, expensive energy and geopolitical risk.

Bitcoin’s muted reaction contrasted with the large moves in Brazilian assets and AI shares. Traders will look to Wednesday’s Fed statement for the next major signal on liquidity and borrowing costs.

Friday’s Completed U.S. Market Results

Monday’s gains followed a completed decline Friday. The S&P 500 fell 0.52% to 7,623.68. The Dow dropped 1.23% to 52,215.16, while the Nasdaq slipped 0.21% to 25,955.34.

For the week, the S&P 500 lost 0.5% and the Nasdaq declined 0.7%. The Dow gained 0.4%. Friday’s energy-sector gain and Monday’s AI rebound show that leadership remains concentrated in a small group of companies exposed to oil, chips, data centers and cloud computing.

Financial Market Outlook

Monday delivered two unusually clear demonstrations of market expectations. Brazil was punished because investors doubted its fiscal path. AI shares rallied because investors still believe enormous spending may produce extraordinary growth.

• Lula’s finance-minister appointment and any immediate Brazilian fiscal commitments.
• Whether Flavio Bolsonaro continues challenging the election result.
• Wednesday’s Federal Reserve decision and Kevin Warsh’s December guidance.
• Alphabet and Microsoft earnings Wednesday, followed by Amazon Thursday.
• Meta’s proposed $95 billion financing and its effect on technology valuations.
• Thursday’s U.S. GDP and PCE inflation reports.
• Further attacks on Saudi oil infrastructure or progress in Tehran talks.
• Whether the 10-year Treasury yield remains below 5%.

The week’s direction will depend on whether AI earnings justify Monday’s optimism and whether easing oil prices can prevent inflation expectations from rising again. Brazil’s market shock also provides a warning: when investors build a large political or policy bet into prices, an unexpected result can erase months of gains in hours.
