More →Brazil’s Stock Market Crashes After Lula’s Upset Victory
Brazil’s stock market lost more than $200 billion in value at the open on Monday after President Luiz Inácio Lula da Silva beat Senator Flávio Bolsonaro in Sunday’s runoff, a result that prediction markets had priced at roughly a one in five chance. The iShares MSCI Brazil ETF, ticker EWZ, a basket of Brazilian stocks that trades in New York like a single share, fell as much as 26% from Friday’s close of about $42.60, touching $31.40 before trimming the loss to about 23% at $32.84 by 10:38 a.m. ET. That is memecoin-sized volatility for a fund built around Brazil’s biggest companies, and it leaves EWZ roughly where it started 2026 after a 34% gain through Friday. The dollar rose as much as 12% against the real on Friday, while the Ibovespa, Brazil’s benchmark stock index, fell as much as 17% to about 170,000 points. For a dollar-based investor, those moves at their worst combine to a loss of about 26%, in line with the ETF’s low. B3, the São Paulo exchange, halted trading for 30 minutes after the Ibovespa fell 10% from Friday’s close, its first circuit breaker since the COVID-19 pandemic. A circuit breaker is an automatic pause meant to slow panic selling, but the index kept sliding after trading resumed. Investors had been positioning for the opposite result since Bolsonaro unexpectedly finished first in the Oct. 4 first round, with 47.03% of valid votes to Lula’s 45.16%. The Ibovespa jumped 7.85% the next day and EWZ gained more than 10% on bets that Bolsonaro would tighten public finances and open the way to lower interest rates. Monday’s drop erased that rally and, at its lows, left the Ibovespa about 11% below its Oct. 2 close. But Lula didn’t just beat Bolsonaro, he also beat prediction markets. Polymarket gave Bolsonaro an<a href="https://x.com/Polymarket/status/2114003200017575948" target="_blank" rel="nofollow external noopener" class="sc-adb616fe-0 dJryYS">> 82% chance</a> of winning the day before the vote, and Kalshi had him near 80% on Sunday morning. Both platforms are<a href="https://decrypt.co/resources/what-are-decentralized-prediction-markets-myriad-polymarket-kalshi" target="_blank" class="sc-adb616fe-0 dJryYS" rel="nofollow"> prediction markets</a>, where a contract that pays $1 if a candidate wins trades at 80 cents when traders see an 80% chance. Polling pointed to a coin flip rather than a favorite, with the latest Datafolha survey tied at 50% each among valid votes and CNT/MDA showing Bolsonaro ahead 50.5% to 49.5% in mid-October. Lula won 51.79% to 48.21%, a margin of about 4.4 million votes, according to Brazil’s Superior Electoral Court. Bolsonaro said on Sunday night that he does not recognize the result and will ask the courts to annul the election, after pledging in August to respect the outcome. He objected to Supreme Court Justice Cristiano Zanin’s decision to extend voting until 7 p.m. at the request of Lula’s campaign, which he said changed the rules midgame. His own campaign had separately asked for extr

AI agents entered Anthropic's commercial systems within 12 hours.
CoinWorld news, researchers say AI agents found a way into Anthropic's business systems in less than 12 hours. The intrusion was not through Anthropic's AI assistant Claude, but through third-party administrative and sales software, the kind of programs typically used to track customers and manage employees. The startup Cathedral was founded by four former employees of the Department of Government Efficiency and recently raised $160 million in July at a valuation of $1.4 billion. Cathedral tested Anthropic through a bug bounty-like program, and the AI agents discovered information such as meeting notes, salaries, and job offer details. Anthropic said that before Cathedral reported its activity, it had already detected some of the activity and shut off its access the same day. Although the researchers accessed limited sales, HR, and IT systems, they did not reach customer conversations with Claude, source code, or model weights.

All seven Anthropic founders have a net worth exceeding $13 billion each.
According to a report from Bijie, Caixin reported on October 27 that the IPO filing submitted by Anthropic on Monday shows that each of the company's seven founders holds approximately 1.4% of the shares, with each person's wealth exceeding $13 billion. This places all seven individuals, including siblings Dario and Daniela Amodei, among the top 300 on the global rich list. The wealth estimates are based on Anthropic's valuation of $965 billion in its most recent funding round. If Anthropic's IPO successfully reaches the $2 trillion valuation previously proposed by investors, before accounting for equity dilution caused by newly issued shares, each of the seven founders would be worth more than $27 billion.
