Extended interview: Former Nebraska senator Ben Sasse has metastatic pancreatic cancer. He spoke with 60 Minutes' Scott Pelley about where America has been and where it could still go.


I've always had a dream of markets where investors can focus on core business results and ignore the noise. A focus on the KPIs that actually matter. 🎉 So excited to share that @fiscal_ai @Kalshi @Benzinga have partnered up to make this a reality. Kalshi KPI markets are now powered by the Fiscal API. 🔥 There are now 15 KPI markets live on Kalshi and will continue to grow. "Predict The Fundamentals."









I’ve always wondered how it feels to pay people to shill a product they don’t love. I hope I never have to find out.

I asked Claude Code to chart my AI reply detection As I thought it's going exponential now There was a small slowdown from July to November last year, then it went back up and with everyone running OpenClaw (I think) it's now going exponentially up again I think @X will have to either 1) detect AI replies and block them with some new tech like key detection as @nikitabier mentioned, and/or 2) default lockdown the reply section to people you follow and to people who subscribe to you or something like that Or the reply section will just become unusable

Do you think Robinhood should be regulated at the state level via casino licenses? If not, then every argument you make against Kalshi is invalid, since by your own logic, something being a gambling company does not imply it should be regulated as a casino. In other words, when you say gambling, you're talking about a cultural definition of gambling, not a legal one.

A new mark for our next chapter — introducing the new CNBC logo. Coming December 13th.


I think most people dunking on Prediction Markets / Kalshi as gambling simply do not understand the modern world. 30% of Robinhood volume in February 2025 was zero day to expiration options. One out of Three. Is Robinhood a gambling company?
