Every information operation playbook already in use, from coordinated inauthentic networks to narrative laundering to targeting journalists, now has a financial payout attached when prediction markets are in the mix.
Today in @WSJopinion on what to do about it. 🔗in comments.

NEW: More bipartisan scrutiny of election betting markets. Sens. Curtis (R-UT) and Warren (D-MA) sent a letter to Kalshi and Polymarket raising concerns about insider trading that could “undermine the overall integrity of the American electoral process.” cnn.com/2026/10/29/politics/…

This is the first block trade ever recorded on US political races.
👀 Someone just bet $500,000 on Texas Gov. Greg Abbott to beat Democratic challenger Gina Hinojosa, per @betint_ai analysis of @Kalshi data. Unclear who placed the bet, but it was an institutional trader. Kalshi odds for Abbott victory currently stand at 68% cnn.com/2026/10/27/politics/…

This is the first block trade ever recorded on US political races, according to our data.
There was also a $100k block trade filed just minutes later on the Republicans to maintain control of the Senate.

In my first report for @CFR_org, I assess the promise and peril of prediction markets tied to U.S. elections and propose nonpartisan reforms to prevent insider trading, strengthen public trust, and protect retail traders.

Very soon we're going to have ETFs that track how, say, a given political party is doing in the prediction markets.
S&P Dow Jones Indices and Kalshi are joining forces to build the next generation of financial markets.
The Dow launched in 1896. The S&P 500 in 1957. The idea was simple: bring individual stocks together into a single benchmark, giving people a clearer view of the broader market.
Over time, products built around those benchmarks transformed investing. Index funds, ETFs, futures, and options gave investors ways to gain diversified market exposure and hedge broad market swings.
These indices became foundations of global finance. More than $20 trillion is indexed or benchmarked to the S&P 500 alone.
Today, this structure extends beyond stocks to bonds, commodities, currencies, and more.
The next step is to bring that structure to the events that shape everyone’s lives.
Through this partnership, S&P Dow Jones Indices and Kalshi will work together to create indices composed of Kalshi event contracts.
Think about what that opens up.
An index of political power. An index of supply chain risk. An index tracking AI’s impact on employment. An index of sports outcomes that affect broadcasters, advertisers, cities, and small businesses. An index of weather risks that shape harvests, energy demand, and business revenues.
Each would bundle event contracts into a single indicator, helping people understand how related risks are evolving.
Over time, products built around these indices could offer diversified exposure to those events and new ways to hedge their impact.
The events that shape our lives could become as easy to track and gain exposure to as the S&P 500.

A federal judge on Monday refused to throw out the insider trading indictment against Gannon Van Dyke, the US solder accused of making $400,000 by betting on Polymarket about Nicolas Maduro's ouster. Van Dyke pleaded not guilty. Trial is slated for December.

Media is changing at AI speed: the open web deteriorating, search shriveling, LLMs rising, hyper-personalization surging, old revenue models breaking.
•AI threatens to finish what the algorithms started: wholly upending journalism as we know it
