Key Discussion Points & Insights
1. Major News Headlines & Market Moves
(00:33–06:52)
- Strait of Hormuz Plan: President Trump unveils “Project Freedom” to open up shipping in the critical oil passageway, but the plan’s lack of military escorts means oil traders remain skeptical, driving Brent crude above $109/barrel.
- “But critics point to how the plan doesn't involve naval escorts. Instead, Project Freedom allows for countries, insurance companies and shippers to coordinate in a bid to get traffic flowing.” — Daniel Bach (01:11)
- Impact on Airlines: Spirit Airlines shutters operations as fuel costs surge, unable to survive the Iran war-related price hikes. Other airlines cap ticket prices for stranded travelers.
- Aluminum Price Shock: The U.S. auto industry faces a severe aluminum shortage and 90% price spike due to supply disruptions and tariffs.
- “The automotive industry depends on aluminum because it's lightweight and the more you use, the better your fuel economy.” — Bob Teda (03:22)
- GameStop’s Bid for eBay:
- GameStop makes a bold, unsolicited $56bn offer for eBay, aiming to rival Amazon, and threatens a proxy fight if rejected.
- “If the e-commerce company isn't receptive to the proposal, he's prepared to launch a proxy fight and take the offer directly to its shareholders.” — Daniel Bach (05:10)
- Anthropic’s Big Investment: Finalizing a $1.5bn joint venture with Blackstone, Goldman Sachs, and others to sell AI tools, especially to private equity-backed firms.
2. Deep Dive: Why Most People Lose on Prediction Markets
(06:52–10:52)
The Promise vs. Reality
- Prediction markets like Kalshi and Polymarket heavily market themselves as democratized platforms where “anyone can monetize their beliefs and win.”
- “There's this one ad on Kalshi that features a young woman who said she was about to not be able to pay her rent, but then made a bunch of money on Kalshi.” — Neil Mehta (07:19)
- The reality: the majority of users end up losing money.
- “On Kalshi...there’s three losers for every single winner. And on Polymarket, around 70% of users have lost money. But on top of that...two thirds of all of the profits on the site have gone to just a tenth of a percent of users.” — Neil Mehta (07:33)
How the Odds Work Against Casual Bettors
- “Mention markets” (betting on whether specific words will be said in speeches/interviews) are popular but misleading.
- “On average, when you bet yes on an event that has a 50% probability, it'll only pay out around 40% of the time. And if you do what most casual bettors do and just put your money on yes at the first price that you see, you'll lose 11% of your money on average.” — Neil Mehta (08:21)
- The expected loss is worse than on Las Vegas slot machines.
Case Study: The Downward Spiral of a User
- John Peterson, a Detroit line cook, suffered a car accident and turned to betting after taking out a loan. Initially turned $2k into $41k on sports and weather markets.
- Lost everything on a technicality in a mention market:
- “He bet all of his money that the rapper A$AP Rocky would say the word rapper on the Tonight show...But the version of his interview that got broadcasted cut that part out. And...a mention only counted if it was actually broadcast on tv. Peterson ended up losing all of his money. When we last spoke with him, he was living in a homeless shelter in Detroit.” — Neil Mehta (09:17)
Winners Are Algorithmic Power Users
- The profits are severely skewed to high-frequency, professional traders using advanced algorithms:
- “Among them are these very large firms that have full time staff members and can pay millions of dollars for specialty data to make algorithmic trades...In fact, it's these highest frequency traders, those in the top tenth of a percent of frequency, where users are most likely to make a profit.” — Neil Mehta (09:49)
- Example: Michael Boss, former pro poker player, runs 60 trades/minute, changing orders up to 30 times/second.
Platform Responses
- Polymarket declined to comment.
- Kalshi claimed similar patterns exist in financial markets, and users are more likely to be profitable than in traditional day trading or sports betting. They’ve also dropped the controversial “pay my rent” ad.
3. BlackBerry: Reinvention Behind the Scenes
(10:52–13:24)
- While BlackBerry’s smartphone fame fizzled, its QNX operating system is now a hidden backbone for modern safety-critical tech in cars, hospitals, and factories.
- “QNX...now accounts for about 50% of the company's revenue, is the fastest growing part of BlackBerry, and it makes foundational software in cars, for hospitals, in all sorts of mission critical applications where safety is key.” — Ben Cohen (11:41)
- BlackBerry’s “turnaround” is real, but relative:
- “The BlackBerry story is now a growth story...Now it's worth saying that it's a growth story in a way. Since its all-time high...the stock is down 96%. Company used to be worth more than $80 billion. Now it has a market cap of $3 billion. But...BlackBerry is sending a message: we are back and we are in your lives even if you don't actually realize it.” — Ben Cohen (12:38)
Notable Quotes & Memorable Moments
- On misleading optimism with prediction markets:
- “But what they don't mention is that you'll probably lose.” — Neil Mehta (07:35)
- On the odds stacked against casual users:
- “Those returns are worse than what you'd see on the average slot machine in Las Vegas.” — Neil Mehta (08:31)
- On profit concentration:
- “Two thirds of all of the profits on the site have gone to just a tenth of a percent of users.” — Neil Mehta (07:46)
- On BlackBerry’s unlikely survival:
- “The idea of BlackBerry being a growth story sounded insane to me.” — Ben Cohen (12:38)

Tone and Takeaways
The episode maintains WSJ’s authoritative, brisk style, blending critical financial headlines with a sharp investigation into online betting markets. The investigation makes clear that prediction markets, often pitched as democratizing finance, predominantly benefit a select few highly sophisticated (and often institutional) players—leaving the average user at a statistical disadvantage.
Listeners are left with both cautionary tales for would-be prediction market participants, and a surprising appreciation for old tech surviving in unseen forms.
