Google's Starlink Competitor Won't Trash Space With Thousands Of Satellites
Satellite communications constellations today could be compared to highways or nuclear weapons in the 1950s. Every major player on the international stage, including Apple, can't envision a future without it despite the massive investment for development and the potential to destroy large swaths of the planet. Taara's approach would remove the need to constantly replenish a decaying satellite fleet like Starlink.
Taara came to fruition in Google X's Moonshot Factory, the same incubator that birthed Waymo. The project aimed to affordably fill the connectivity gaps in the planet's high-speed internet network. Taara's efforts center around silicon photonic chips, technology that can send and receive data through the air. The system, called Lightbridge, shoots very narrow, invisible light beams between terminals to transmit data at speeds up to 20 gigabits per second over 12 miles.

The Taara Lightbridge is envisioned as a much cheaper alternative to laying fiber optic cables. If it's cheaper than laying a cable, it must be pennies compared to a reusable rocket launch. According to the Verge, the project trailed the system in two densely-populated places where traditional networks would be cost-prohibitive: Kinshasa, the Congolese capital, and the Coachella Festival.
The issues with Starlink, Taara's largest competitor, are becoming evident as its satellite constellation scales up. The fleet has around 6,000 satellites with aspirations of 42,000 boxes swirling around our blue marble. At full scale, there could be as many as 8,000 Starlink sats burning up in the atmosphere every year, which could spew over 1,000 tons of aluminum oxide into the atmosphere. The absurdly high levels of aluminum oxide pollution would deplete the ozone layer, the crucial barrier protecting the planet from the Sun's ultraviolet radiation.
However, Taara wouldn't be able to completely supplant Starlink. Governments see military value in having a satellite communications constellation. The People's Republic of China is developing its own constellation to match the capabilities that Starlink offers the American military. A ground-based system can't provide the same instant global connectivity. For Taara's network to expand, new Lightbridge terminals need to be installed by connectivity is need. Those towers would also quickly become targets during an armed conflict, like airports or bridges.

Elon Musk Threatens to Sue Apple Over Claims It Favors OpenAI
Elon Musk claimed late Monday that Apple gave preferential treatment to OpenAI, a prominent competitor of his artificial intelligence company, and he threatened to sue the consumer tech giant for 'an unequivocal antitrust violation.' Mr. Musk's A.I. company, xAI, released a new version of its chatbot, Grok, last month. Mr. Musk has recently posted on his social media platform X about how well his chatbot was doing with rankings in Apple's App Store. But on Monday, Mr. Musk started posting that Apple was intentionally favoring OpenAI instead. Apple has a partnership with OpenAI to integrate its chatbot, ChatGPT, into Apple products. 'App Store, why do you refuse to put either X or Grok in your 'Must Have' section when X is the #1 news app in the world and Grok is #5 among all apps?' Mr. Musk wrote. 'Are you playing politics?' Hours later, Mr. Musk posted that 'Apple is behaving in a manner that makes it impossible for any AI company besides OpenAI to reach #1 in the App Store.' 'xAI will take immediate legal action,' he added. Mr. Musk frequently turns to legal threats against competitors and critics over perceived injustice, sometimes resulting in lawsuits and other times fizzling out after a few social media posts. As of Tuesday afternoon, xAI did not appear to have filed a lawsuit in federal court. Representatives for xAI and Apple did not respond to requests for comment. A fact-checking feature run by X users, called Community Notes, added a note to Mr. Musk's post that said chatbot apps made by companies other than OpenAI have reached the number one spot on the App Store. Mr. Musk has feuded with OpenAI and Apple before. Mr. Musk previously criticized Apple in 2022, when he said the company had threatened to remove his social media app from its App Store altogether after he relaxed content moderation rules. Apple's policies prohibit apps that include hateful speech or content. Mr. Musk later met with Tim Cook, Apple's chief executive, and clarified it was a 'misunderstanding.' Mr. Musk co-founded OpenAI, but left the company in 2018, citing disagreements with the other co-founders over the company's direction. He sued OpenAI last year, claiming that the company and two of its founders, Sam Altman and Greg Brockman, had breached its founding contract by putting commercial interests ahead of the public good. (The New York Times has also sued OpenAI for copyright infringement. The company has denied wrongdoing.) Mr. Altman, who remains the chief executive of OpenAI, has denied the allegations.

Sign Up Now! Zooming in further, the wireless infrastructure provider stock's underperformance becomes more evident when compared to the Real Estate Select Sector SPDR Fund's (XLRE) marginal decline over the past 52 weeks. Shares of American Tower fell 4.2% on Jul. 29 after the company slightly lowered its 2025 organic tenant billings growth outlook for the U.S. and Canada to about 4.3% and cut its leasing forecast by roughly $5 million. Management also reduced its 2025 net income forecast to $2.3 billion - $2.4 billion, citing weaker foreign currency impacts. Additionally, Q2 2025 net income dropped 58.1% year-over-year to $381 million, pressuring investor sentiment despite stronger-than-expected quarterly revenue of $2.6 billion. For the fiscal year ending in December 2025, analysts expect American Tower's AFFO per share to decline 3.1% year-over-year to $10.21. However, the company's earnings surprise history is promising. It beat the consensus estimates in the last four quarters. Among the 22 analysts covering the stock, the consensus rating is a 'Strong Buy.' That's based on 16 'Strong Buy' ratings, two 'Moderate Buys,' and four 'Holds.' This configuration is slightly less bullish than three months ago, with 17 'Strong Buy' ratings on the stock. On Jul. 30, BMO Capital's Ari Klein cut American Tower's price target to $245 but maintained an 'Outperform' rating, citing mixed results with strong international, data center, and services performance, and noting that a 50% year-over-year rise in U.S. carrier applications and near-record services revenues. As of writing, the stock is trading below the mean price target of $246.45. The Street-high price target of $281 implies a potential upside of 36.1% from the current price.
