You could have made more than half a million dollars in 71 minutes...
You just had to know in advance that the U.S. was about to take out Iran's supreme leader – or you could have made a really lucky guess.
We don't know which one applied to "Magamyman." Here's what we do know: This user placed this bet on Polymarket, a global prediction market, barely an hour before the U.S. and Israel began striking Iran. The winning bet cleared hundreds of thousands of dollars.
War in Iran is just one of many topics trading on Polymarket. On the same day Magamyman made his winning bid, more than half a billion dollars changed hands on the platform.
You can bet on just about anything nowadays...
The future price of cryptocurrencies... a city's daily temperature... or how much money people will wager on sports this year. (Yes, you can place a bet on betting.)
In December, more than $13 billion flowed through prediction markets like Polymarket. That's up from about $100 million per month in 2024.
And unlike Magamyman, few people win in the prediction markets. By some estimates, up to 90% of users lose money.
Those odds aren't for me.
I often hear folks lump the stock market right in there with prediction markets and other forms of straight-up gambling.
And it's true that many so-called investors treat the stock market like a giant casino... where they can gamble with thousands or even millions of dollars for a shot at "hitting it big." More often than not, they crash and burn.
But unlike in a casino or Polymarket, stock market investors can boost their odds of buying winning stocks.
You just need the right tools...
And you can get one of them from my friend Marc Chaikin, founder of our corporate affiliate Chaikin Analytics.
During his decades on Wall Street, Marc created proprietary stock indicators – like the industry-standard "Chaikin Money Flow" – that are used by the biggest firms and traders all over the world.
These days, he gives everyday investors access to these tools as part of an extraordinary investment strategy.
It's designed to make folks money in any market condition – including bear markets.
And if Marc's latest prediction is right, it's going to come in handy...
This past Wednesday, Marc warned that a "bear market window" is opening. And when it does, this event could usher in the greatest potential losses we've seen in years.
The gamblers will be in trouble. But investors who position themselves correctly could beat the odds.

Now, let's get to this week's Q&A... And as always, keep sending your comments, questions, and topic suggestions to feedback@healthandwealthbulletin.com. My team and I read every e-mail.
The Benefits of Berries
Q: Sorry to admit, Doc, but I don't love blueberries. Are other berries just as healthy? – F.M.
A: You're in good company, F.M. One of my researchers hates blueberries (but I keep her on the team anyway).
Overall, blueberries are a powerhouse that other berries just can't beat. But if you need an alternative, some other berries have lots of great and often similar benefits...
- Cranberries contain compounds that help prevent bacteria like food-borne pathogens (for example, E. coli and staphylococcus) from sticking to cells. They can also keep plaque from sticking to the surface of your teeth. And they are rich in polyphenol antioxidants, which have been shown to help inhibit cancer growth, particularly breast cancer.
- Blackberries help lower cholesterol and fight cancer. And they improve your immune system because they're packed with vitamin C. Their high amounts of potassium and salicylate (an ingredient in aspirin) may help protect you against high blood pressure.
- Raspberries (probably my second favorite after blueberries) are packed with flavonoids like ellagic acid. Research shows ellagic acid inhibits tumor growth in certain cancers. And it kills cancer cells without harming healthy cells.
- Strawberries are also full of ellagic acid. Like all berries, they have lots of cancer-fighting antioxidants and anti-inflammatories. They can relieve many of the symptoms of rheumatoid arthritis, especially pain.
These berries are all great for your health. But don't give up on blueberries...
If you're not a fan of their flavor or texture, try blending them in a smoothie with other berries or crushing them before adding them to yogurt or oatmeal. That way you'll still get all the benefits that only blueberries can offer.
