One thing's for sure, these prediction markets aren't going away.

In fact, more companies are launching them every day, like the investing app Robinhood and the sports betting apps DraftKings and FanDuel.

And even President Trump's media company announced it's launching its own prediction market that will be available on Truth Social, called TruthPredict.

That's all for today, Tuesday, February 17th.

Thanks for listening.

See you tomorrow.

More than a decade ago, Walmart brought on a new CEO.

His name was Doug McMillan, and he had his work cut out for him.

At the time, Walmart's reputation was in the gutter.

Online shopping and Amazon were on the rise, and other retailers like Costco and Discount Grocers were stealing market share.

Walmart's future wasn't totally clear.

Fast forward to today, and Walmart is doing much better.

And Macmillan set the company on a course to hit a trillion-dollar market cap, which it did just a few days ago.

Last month, after 12 years as CEO and more than three decades at the company, Doug Macmillan retired.

Our colleague Sarah Nossauer interviewed him before his last day.

Sarah, you spoke to Doug about his tenure at Walmart.

What stood out to you about the conversation?

So what would you say, like, what defined his tenure here?
