Elon Musk's Grok-4 was asked to predict the World Series. After 4.5 minutes, it chose the Dodgers.
Sports betters rely on a variety of tools for their wagers. Betting sites like FanDuel and BetMGM have their own odds, as do predictions markets like Polymarket. Grok-4, the newest iteration of xAI's large language model, may be their next resource.
During the launch of Grok-4 — just a day after its previous iteration, Grok-3, went on several antisemitic rants — Elon Musk and his xAI panel prompted the chatbot to calculate odds on the World Series.
After an over four-minute wait, the model predicted both a likely winner and a high-value edge case.
During the presentation, an xAI employee called Polymarket the "C-curve of truth" that "aligns with what reality is most of the time." They wanted Grok-4 to do the same.
"We can try to take these markets and see if we can predict the future as well," he said.
According to the demo, Grok-4 first gathered the current standing of each team and their market odds. It cited ESPN, Bleacher Nation, FOX, and BetMGM.
Grok-4 then calculated its own odds based on FanGraph data. After comparing the internally calculated odds against the betting sites, it identified an Alpha and Edge.
The Alpha — an excess return over the market — recognized the Dodgers as overvalued in Grok-4's calculations. The Edge — a bet with positive expected value — was given to the Mariners and Astros.
Ultimately, Grok-4 found the Dodgers most likely to win, with a 21.6% chance. For a potentially higher return, Grok-4 recommended betting on the underpriced Mariners.
Grok-4's predictions are not far off from the current odds on Polymarket, the popular betting site. The Dodgers also dominate there, with an even greater 28% odds. The Mariners only have 2% odds on Polymarket.
To calculate these odds, Grok-4 needs to use its "Heavy" reasoning capabilities, which cost the user $300/month for early access. This means a response may take longer than traditional chatbot responses. During the demo, it took 4.5 minutes for Grok-4 to calculate the World Series odds.
"That's a lot of thinking," Musk said.
How confident is Grok-4 in its guess? It's just a prediction, as the chatbot's own disclaimer demonstrates: "Grok is not a financial advisor; please consult one."

White House indicates Trump doesn't support federal contracts for Musk's AI company
White House press secretary Karoline Leavitt said Wednesday she does not think President Trump supports federal agencies contracting with Elon Musk's AI company. 'I don't think so, no,' Leavitt said. Asked if Trump would then want the government to cancel a recently announced contract with Musk's AI venture, Leavitt said she would talk to the president about it. The comments come roughly a week after Musk's company, xAI, scored a contract for up to $200 million with the Department of Defense, alongside three other major tech firms. xAI, Anthropic, Google and OpenAI all received contracts with the same ceiling from the Chief Digital and Artificial Intelligence Office to help boost the agency's adoption of advanced AI. That announcement came on the same day xAI unveiled a suite of AI products for U.S. government customers, which it refers to as Grok for Government. Trump and Musk have been locked in a bitter feud since the Tesla CEO departed his role as a special government employee at the end of May. Musk has criticized Trump's signature policy bill and floated the idea of starting another political party, while Trump has suggested he could harm Musk by canceling federal contracts with his businesses, like SpaceX.

Apple introduces AppleCare One subscription service to protect devices
Protecting electronic devices is a priority for most people, and Apple has come up with a plan to help its customers do just that. The tech giant unveiled its new AppleCare One service on July 23, a subscription service that allows customers to protect up to three products in one plan for $19.99 per month. Customers will also have the option to add more devices at any time for $5.99 per month for each device. Apple says the plan offers customers "one-stop service and support from Apple experts across all of the Apple products in their plan for simple, affordable peace of mind." Starting July 24, customers in the U.S. can sign up for AppleCare One directly on their iPhone, iPad or Mac, or by visiting their nearest Apple Store, the company said in a news release. "Built on the trusted foundation of AppleCare+, AppleCare One extends that same reliability and makes it easier than ever to protect the products you love and depend on like iPhone, iPad, and Apple Watch, combining simplicity and exceptional value," said Bob Borchers, Apple's vice president of Worldwide Product Marketing, in the news release. What does AppleCare One protect against? According to Apple, AppleCare One includes all of the benefits of AppleCare+, including unlimited repairs for accidents like drops and spills, 24/7 priority support from Apple experts, quick and convenient Apple-certified service and battery coverage. Apple says the plan also expands theft and loss protection beyond iPhones to also cover iPads and Apple Watches. Elon Musk fans flock to new Tesla Diner: See the opening day photos How much does AppleCare One cost? The company says AppleCare One pricing is the same regardless of the products that are covered – $19.99 per month. This means a customer can enroll their iPhone, iPad and Apple Watch in an AppleCare One plan instead of enrolling each device in separate AppleCare+ plans. Additional items can be added for $5.99 per month for each device. Are existing devices eligible for AppleCare One coverage? Apple says customers can now add products they already own that are up to four years old to an AppleCare One plan if they are in good condition. To verify "good condition," products may be required to undergo a diagnostic check using a customer's iPhone or iPad, or at an Apple Store, prior to being added to the plan, Apple said.

SpaceX Has the Nerve to Be Mad About a Competitor's Massive Satellites Littering Earth Orbit
Despite owning more than half of the satellites currently in low Earth orbit, SpaceX is complaining about AST SpaceMobile's BlueBird constellation and how it'll introduce added risks. In a letter sent to the Federal Communications Commission (FCC), SpaceX raised concerns that AST SpaceMobile poses a threat to the sustainability of low Earth orbit. Elon Musk's space venture accused the Texas startup of underestimating collision risks in space and whether its satellites pose a threat to people on the ground during reentry. To be fair, these are valid concerns, but the accusations are laughably ironic coming from SpaceX. The company operates more than 7,800 satellites—currently around 60% of all satellites in orbit—and they've had more than a few close calls with other objects. In a case of the pot calling the kettle black, SpaceX calls on the FCC to 'carefully scrutinize' AST's plan of launching its BlueBird satellite constellation to ensure it doesn't 'present untenable risks to space sustainability.' SpaceX claims that AST's orbital debris mitigation plan 'uses inconsistent and unrealistic assumptions to significantly downplay the risk of its satellites.' AST SpaceMobile is seeking to create the first space-based cellular broadband network directly accessible by cell phones, but its satellites are obnoxiously big. The company's prototype satellite unfurled its giant array in late 2022, outshining most objects in the skies except for the Moon, Venus, Jupiter, and seven of the brightest stars. Prior to unfurling its tennis court-sized array, the satellite exhibited a brightness magnitude of around +3.5, making it visible to the naked eye. However, after deploying its antenna array, its brightness increased by about 2 magnitudes. Around two years later, AST launched five more satellites into orbit, which were just as large as the prototype, but future models could be even larger. The company wants to launch 243 more of its satellites. A second-generation BlueBird is set to launch in the next few weeks following the FCC's approval. SpaceX claims that AST's proposed constellation is filled with 'critical gaps and inconsistencies' that have to do with avoiding collisions with other objects in space and preventing debris from falling to Earth. In its letter, SpaceX warns that AST launching its satellite 'without resolving these issues would be irresponsible, potentially subjecting all other operators in LEO (low-Earth orbit) to unnecessary risk.' Although SpaceX's Starlink satellites have not had an orbital collision incident, they have had a couple of close calls. In September 2019, the European Space Agency's Aeolus satellite was forced to carry out an orbital maneuver to dodge a Starlink satellite. China also reported that its Tiangong space station crew had to conduct maneuvers in orbit to avoid the satellite constellation. The risk that the satellites pose for future collisions and space debris generation is a growing concern since they account for more than half of close encounters tracked in low Earth orbit, according to space tracking experts. But there's more to the hypocrisy and the accusations that SpaceX is levying at its rival. Similar to AST, SpaceX's satellites have also been a visual orbital nuisance. Astronomers have raised concern that Starlinks are interfering with their observations of the universe, appearing as bright streaks in telescopic images. SpaceX was also involved in multiple disputes over the use of spectrum bands that interfere with other networks; the company has been accused of using its position in the industry as a main provider of rocket launches to coerce other companies, like OneWeb, to share their wireless spectrum rights. The two companies are no better than one another, and they are locked in a competitive cycle as they both race to deliver satellite connectivity to smartphones. AST has previously accused SpaceX of attempting to 'intimidate and bully' its competitors after Musk's space venture sent a previous letter to the FCC last year claiming AST is spreading misinformation to try and hamper its work. As SpaceX and AST continue to squabble, both companies are contributing to low Earth orbit's increasing congestion.
