1. Brazil Presidential Election: Lula’s Historic Comeback

Incumbent leftist President Luiz Inácio Lula da Silva (nearly 81) defeated far-right challenger Flávio Bolsonaro (son of former President Jair Bolsonaro) in the runoff, securing a fourth non-consecutive term with about 51.8% of the vote to Bolsonaro’s 48.2% (a margin of roughly 4.4 million votes).[2]

This marks a dramatic turnaround—Lula lost the first round earlier in October—and is the first time since Brazil’s return to democracy that a candidate who placed second in the first round won the presidency. Lula called it a “defeat for denialism” and a win for democracy. Bolsonaro refused to concede, citing a last-minute extension of polling hours (requested by both sides due to weather/transport issues) and plans to seek annulment. Brazilian markets tumbled on the surprise result. The outcome bucks a recent right-wing wave in Latin America and is seen as a setback for U.S. President Donald Trump’s regional influence.[3]

2. U.S. Midterm Elections: Final Stretch

With about a week until Election Day, candidates are making final pitches as control of Congress hangs in the balance. President Trump and former President Obama held rallies (including in battleground Michigan). Coverage focuses on House/Senate outlooks, attack ads, spending, and issues like inflation and redistricting. Spiritual leaders have also called for peace on Election Day.[4]

3. Israeli Elections: Referendum on Netanyahu

Israelis prepare to vote tomorrow (October 27) in the first national election since the October 7, 2023, Hamas attacks and subsequent wars in Gaza and with Iran. It is widely viewed as a referendum on Prime Minister Benjamin Netanyahu’s leadership. Polls show a tight race between Netanyahu’s Likud-led right-wing/religious bloc and an opposition alliance headed by former military chief Gadi Eisenkot (Yashar party). Neither side is clearly projected to reach the 61 seats needed for a majority in the 120-seat Knesset, raising the possibility of prolonged coalition talks or a caretaker government. Key issues include security, the handling of October 7 failures, international isolation, and domestic policies. Trump has endorsed Netanyahu.[5]

4. Serbia: Student-Led Movement Ousts Longtime Leader

In a snap parliamentary election, a student-backed opposition movement defeated longtime strongman Aleksandar Vučić and his United Serbia party. Vučić conceded defeat after more than a decade in power (amid protests over corruption, surveillance, and democratic backsliding). This is described as a political earthquake and another setback for right-wing/populist leaders.[6]

5. Tech/Business: Anthropic Files for Blockbuster IPO

AI company Anthropic (maker of the Claude chatbot) publicly filed its S-1 registration with the SEC, paving the way for a potential Nasdaq listing (ticker: ANT) as soon as mid-to-late November. It disclosed explosive growth: $16.3 billion in revenue for the first half of 2026 (up ~1,300% year-over-year), with strong enterprise adoption. However, it reported a massive $80.7 billion net loss (largely accounting-related from financing) and highlighted significant AI risks (including existential ones). The IPO could raise tens or hundreds of billions at a valuation potentially in the $1.5–2 trillion range, making it one of the largest ever and a major test for AI stocks. Stocks rose on the news.
