Welcome to Technology Daily, your go-to source for the latest in tech news. I'm your host, and today is June 21st, 2026. We've got a packed show for you, covering everything from fake viral betting videos to breakthrough batteries, legal battles in the skies, a critical security deadline, and much more. Let's dive right in.
Our top story today comes from The Verge, and it's one that should make you think twice before trusting those viral videos you see online. A Wall Street Journal investigation has revealed that Polymarket, the popular prediction betting platform, has been secretly paying people to film themselves placing fake bets and celebrating fake wins on social media. The WSJ identified over eleven hundred deceptive clips and even spoke to creators who confirmed the company paid them to make the content, without ever disclosing that in their videos. Some of the giveaways are subtle but telling. In one clip, a closer look shows someone visiting 'poiymarket.com' rather than the real 'polymarket.com'. Critically, according to the investigation, none of the bets shown in those videos were real. It's a stark reminder to be skeptical of what you see on your social feeds, especially when money and investment are involved.
Next up, some genuinely exciting news from the world of electric vehicles and energy storage. Researchers have found that a Chinese sodium-ion battery is performing far better than anyone expected, with production quality and design features that are actually comparable to Tesla's batteries. Why does that matter? Well, sodium is significantly cheaper and more abundant than lithium, which powers most EV batteries today. If engineers can address the remaining challenges, specifically cold-weather charging and overall energy density, sodium-ion technology could become a serious, more affordable alternative for both electric vehicles and large-scale energy storage. This is one to watch.
Speaking of batteries, there's a sobering research report out this week warning that the global cobalt supply chain is far more fragile than we thought. Cobalt is a key ingredient in many EV batteries, and researchers say a single disruption in the supply chain could trigger cascading problems across multiple countries and industries. The researchers are calling for system-wide coordination to protect against these vulnerabilities before a local shock turns into a global crisis. With demand for EVs only growing, this is a critical issue for the entire industry.
Now, let's take to the skies β or try to. The promise of electric air taxis has been one of the most exciting stories in transportation tech, but right now, some of the biggest players in the space are finding themselves grounded not by engineering challenges, but by lawyers. Joby Aviation and Archer Aviation, two of the leading air taxi companies in the US, sued each other last year. Joby accused Archer of corporate espionage, while Archer claimed Joby was hiding ties to China. And then earlier this year, Archer filed a patent infringement suit against yet another rival, Vertical Aerospace. The air taxi dream is real, but the road to commercialization is apparently paved with courtroom battles.
On the security front, there's an urgent heads-up for Windows and Linux users. The cryptographic keys that secure your computer's boot sequence are set to start expiring on June 24th. That is literally days away. These keys are fundamental to keeping your system secure when it starts up, and if yours expire without being updated, it could leave your machine vulnerable. If you haven't already, it's worth checking with your system's update tools or your IT team to make sure you're covered before that deadline hits.
Moving over to artificial intelligence, The Atlantic has done something quite remarkable for transparency. Reporter Alex Reisner uncovered four massive datasets of music that have been used to train AI models and made all of them fully searchable for the public. We're talking huge collections here β one has 12 million tracks, another has 9 million, and two more each contain over 100,000 songs. Companies like Google and Stability AI have confirmed using some of these datasets in published research papers. The move raises big questions about copyright, consent, and what artists are owed when their work is used to build AI systems.
Norway is also making waves in the AI policy space. The country is reportedly imposing broad restrictions on the use of artificial intelligence by elementary school kids. The move reflects growing concerns from policymakers around the world about the impact of AI tools on children's learning and development. Norway is joining a growing list of countries grappling with how to balance the benefits and risks of AI in education.
Let's talk space. NASA is testing an exciting new prototype rover called Ernest, and it's pretty impressive. The rover can drive faster than previous designs and, perhaps most interestingly, can actually lift its wheels to climb over obstacles. NASA shared footage of the tests, and it looks like a significant leap forward for the kind of mobility future planetary rovers will need. On top of that, NASA is also preparing to launch its Swift Boost mission later this month, a rescue operation designed to save a falling space telescope. It's a busy time at the agency.
On the quantum computing front, researchers have found a surprisingly elegant new way to control quantum emitters. By simply twisting layered sheets of a material called hexagonal boron nitride, scientists can dramatically alter the light produced by quantum emitters embedded within it. This twist technique gives researchers an unexpected new level of control over components that could eventually power quantum computers, communications systems, and sensors. Quantum computing has been tantalizingly close for years, and breakthroughs like this keep nudging the technology forward.
In gaming news, we have a sad farewell to mark. Bobby Prince, the legendary composer behind the music of the original Doom and other classic shooters, has passed away. His work defined an era of gaming and influenced countless soundtracks that followed. The gaming community is mourning a true pioneer.
On a lighter gaming note, Epic Games is working on a ground-up rebuild of its game launcher, promising it will be five times faster than the current version. The new Launcher V2 will go through a private beta before a wider public release. Anyone who's ever waited for the Epic launcher to crawl to life before playing a game will probably welcome this news.
And finally, a quick note on the smartphone market. Nothing's budget brand CMF has confirmed it will not be releasing a new phone this year. The reason? RAM prices. The so-called RAMageddon has sent memory costs soaring, making it impossible for the company to build a device that represents a genuine step forward at a price point that makes sense for the budget-focused CMF brand. It's a reminder that global supply chain pressures have very real consequences for the gadgets consumers can buy.
That wraps up today's edition of Technology Daily. From fake viral bets to real battery breakthroughs, legal air taxi tangles to a critical security deadline, it has been a fascinating day in tech. Thanks so much for tuning in. Stay curious, stay informed, and we'll see you back here tomorrow.
