S&P Dow Jones Indices has partnered with prediction market platform Kalshi, allowing the exchange to offer event contracts settled on official values of S&P DJI's benchmarks, and making Kalshi a preferred platform for such contracts. The two will also explore building indexes from Kalshi's prediction market data, which could track expectations on economic, political and sporting events, though no timeline was disclosed. The deal follows moves by traditional market operators into prediction markets, including Intercontinental Exchange's commitment of up to $2 billion to Polymarket in October 2025 and Nasdaq's August partnership with Kalshi on market surveillance technology. Separately, S&P Global said it completed its acquisition of blockchain security firm OpenZeppelin, with financial terms undisclosed.

- Utah AG sues Kalshi, pursues profits from prediction market company
Utah Attorney General Derek Brown sued Kalshi, its affiliates and two Susquehanna trading companies, alleging the prediction market platform has facilitated illegal betting in the state since 2024. Utah asked the court to compel the companies to return about $30 million to $60 million in profits and to stop sports, election, politics and culture bets in Utah. The lawsuit alleges Kalshi illegally served more than 32,000 users in the state, causing significant losses. A judge had earlier ruled for Utah in August, and an appellate court denied Kalshi's injunction request in September. The case is one of many filed by states against prediction market platforms such as Kalshi and Polymarket, as the U.S. Supreme Court considers New Jersey's case.
- Kalshi CEO says state-led oversight of U.S. prediction markets would push them out
Kalshi CEO Tarek Mansour said at DC Fintech Week that the legal fight over prediction markets is really a choice between federal oversight in the U.S. and the industry moving offshore. He said he feels “pretty good” about the company’s legal standing and rejected the argument that sports event contracts lack economic consequences. States accuse prediction markets of illegal sports wagering, while Kalshi and the CFTC argue the federal agency should be the sole watchdog; federal appellate courts have split, with one ruling for Kalshi and two for the states, and New Jersey has asked the U.S. Supreme Court to take the case. Mansour also rejected accusations of inflated trading volume in bitcoin and ether perpetual-futures markets, attributing recurring trade sizes to fixed-size orders from market makers. The CFTC recently issued a rule and proposed another to place event contracts under the swaps definitions it polices.

These are market prices showing the distribution of priced outcomes, not a forecast, survey, or central bank commitment. Kalshi is a US exchange regulated by the Commodity Futures Trading Commission.

- The Unexpected Chairman of Vietnam's State Securities Commission and the Journey to 'Founding' a Market from Zero
In late 1987, Lê Văn Châu, then working at the State Bank, held a meeting lasting until 10 p.m. with top leaders including General Secretary Nguyễn Văn Linh, focused on how the US economy, government bonds and capital markets worked, which sparked the idea of building a capital market in Vietnam. In early 1991, Châu formally proposed researching a stock market amid surging demand for medium- and long-term capital for infrastructure, a sharp decline in credit aid from the Soviet Union and Eastern Europe, and heavy pressure on commercial banks. The proposal faced concerns about securities being associated with “capitalism”; in response to questions from adviser Phạm Văn Đồng and General Secretary Đỗ Mười, Châu argued that securities are a product of human civilisation that could operate under state management in a socialist system, and the Politburo approved the research. In 1992, the State Bank gathered a temporary research group of well-trained young officials, even though no one truly knew how the market would operate.
- Why Petroleo Brasileiro SA Petrobras ADR Crashed Today
Petrobras ADRs (PBR) fell 16.63% and PBRA 18.27% on Monday, joining a rout in Brazilian stocks after President Luiz Inácio Lula da Silva beat conservative challenger Flávio Bolsonaro 51.8% to 48.2% in the runoff, a result that surprised investors who had expected a Bolsonaro win. Bolsonaro is refusing to concede and alleges the administration suppressed votes in key districts, while nearly all other Latin American leaders have congratulated Lula, with only Argentine President Javier Milei holding back. The article notes that since 2023 Lula has placed government control at the center of energy policy, imposing price controls on domestic fuel sales, ending privatization of Petrobras's assets, and ordering the company to expand production and favor capital investment over dividends. These moves may look negative in the short term but could pay off over the longer term, and Petrobras shares trade at 6.6x trailing earnings.
- Can Pinterest Stock Jump 50%?
Pinterest (PINS) stock trades 44.2% below its highest close of the past two years, $40.00 on February 7, 2025, and cash generated over the last twelve months equals 10.2% of its market value, versus 4.3% for the median S&P 500 company. Free cash flow rose to $1,280 million in the twelve months to June 2026, from $1,047 million a year earlier and $370 million in the twelve months to June 2023, while sales grew 16.6%. Pinterest held $1,275 million of cash and short-term investments at June 30, 2026, roughly matching its $1,197 million of debt, which stood at $137 million a year earlier. Costs have outpaced sales: the fiscal Q2 2026 operating margin was -3.5% versus -0.4% a year earlier, and management guided fiscal Q3 revenue growth of 13% to 15%, down from 18%, while raising its full-year adjusted EBITDA margin expectation to about 30% from about 29%. The article says the share price appears to assume slower growth and higher costs will erode cash, and points to the fiscal Q3 report expected on October 29, 2026 as the next test.
- Dogecoin Is Finally Getting Serious About Offering Real Utility to Users. Here's What That Could Mean for the Price of DOGE.
Dogecoin Labs is an independent organization formed by the teams behind a Dogecoin wallet, an application network and merchant payment tools, partnered with the Dogecoin Foundation, while House of Doge contributes intellectual property and development operations in exchange for an equity stake. Its three products are MyDoge, a wallet and app that Dogecoin Labs says has more than 500,000 users without paid acquisition; DogeOS, an EVM-compatible application layer whose public testnet opened on Sept. 30; and Such App, a merchant point-of-sale and invoicing tool still in beta. The author calls the effort welcome news but says execution is the challenge, since active wallet users have not been disclosed and Dogecoin competes with Ethereum, Solana and stablecoins such as USDC and Tether. DOGE trades at $0.08, down 89% from its 2021 peak of $0.74 as of Oct. 23, and the author is skeptical the initiative will have much effect on the price until Dogecoin Labs delivers tangible results.
- Netflix Drops 4% as Engagement Worries Outweigh Earnings Beat; Disney and Spotify Slip
Netflix shares fell 4% to $63.54 in afternoon trading, even though the company beat Q3 2026 earnings expectations with GAAP EPS of $0.87. Revenue matched estimates, but full-year revenue guidance landed at the low end of the outlook and slightly below consensus, and the 2026 advertising revenue forecast was cut to $2.7 billion from $3 billion. The main worry is engagement: Netflix reported no growth in watch hours for the quarter, and co-CEOs Greg Peters and Ted Sarandos acknowledged the need for better execution in the U.S. Supporters point to improved churn and $4.8 billion of Q3 repurchases funded by free cash flow, while the Q4 2026 content slate is seen as the next test. The company also trimmed its full-year free cash flow outlook to $12 billion from $12.5 billion due to a Q4 real estate transaction.
- Is Bitcoin the Best Cryptocurrency You Can Buy Right Now?
The author notes that Bitcoin's price is often treated as tied to daily news and cites widely different forecasts: Ark Invest (Cathie Wood) projects nearly $800k by 2030, while JPMorgan Chase says it could theoretically go to zero, with a base case of 10% returns per annum. The author cannot guarantee Bitcoin will outperform other cryptocurrencies over 1, 5, or 10 years, but judges it the safest crypto investment at present, given its stability, institutional trust and track record across market cycles. Solana and Ethereum are both in major network upgrades, while the author sees integrating quantum-safe encryption as a key future milestone for Bitcoin. The author says that if only one cryptocurrency were chosen in the final quarter of 2026, it would be Bitcoin.
