Teens outperform Gemini, ChatGPT at top international math Olympiad
Held in Queensland, Australia, the 2025 edition of the global competition consisted of 641 young mathematicians under the age of 20 from 112 countries, five of whom achieved perfect scores of 42 points, something neither AI model could replicate, a report in Popular Science stated.
Google announced that its advanced Gemini chatbot managed to solve five of the six problems presented at the competition, earning a total of 35 out of 42 points, a gold-medal score.
'We can confirm that Google DeepMind has reached the much-desired milestone, earning 35 out of a possible 42 points — a gold medal score,' IMO president Gregor Dolinar stated in a quote shared by the tech giant, the report said.
'Their solutions were astonishing in many respects. IMO graders found them to be clear, precise, and most of them easy to follow,' he added. OpenAI, creator of ChatGPT, also confirmed that its latest experimental reasoning model achieved a score of 35 points, the report added.
According to OpenAI researcher Alexander Wei, the company evaluated its models using the same rules as the teen competitors. 'We evaluated our models on the 2025 IMO problems under the same rules as human contestants. For each problem, three former IMO medalists independently graded the model's submitted proof,' Wei wrote on social media, as per the report.
This year marks a significant leap for AI in math competitions. In 2024, Google's model earned a silver medal in Bath, UK, solving four out of six problems. That attempt took two to three days to solve. In contrast, the latest Gemini model completed this year's test within the official 4.5-hour time limit.
The IMO acknowledged that technology firms had 'privately tested closed-source AI models on this year's problems,' which were the same as those faced by the human contestants.

Sundar Pichai Net Worth: How much does the Google CEO earn and where does he rank among the world's richest
There's no stopping Sundar Pichai! Pichai Sundararajan, better known as Sundar Pichai, the soft-spoken CEO of Google and Alphabet, has recently stepped into the club of the rich. Which club is it? Well, it's the much-coveted billionaire's club! In 2024, Pichai received a total compensation package of approximately $10.73 million, which includes his base salary, stock awards, bonuses, and company perks. While this is far less than the massive one‑time $226 million stock grant in 2022, his annual income remains solid. So, what is his net worth in 2025? Sundar Pichai: Net worth in 2025 As of July 2025, Sundar Pichai's net worth is estimated at $1.1 billion, according to the Bloomberg Billionaires Index. Pichai has been Google's CEO since August 2015. He was appointed to the role on August 10, 2015. In December 2019, he also became the CEO of Google's parent company, Alphabet Inc. So, it took him nearly a decade to finally become the billionaire CEO. Pichai holds roughly 0.02% of Alphabet, which translates to about $440 million in equity value. Over the years, he has sold $650 million worth of shares; if he had kept them, they might now be worth over $1 billion more. How much did he earn in 2024: A detailed breakdown Alphabet's 2025 proxy filing reveals that Pichai made $10.73 million in total in 2024, up from approximately $8.8 million in 2023. This drop from the extraordinary $226 million compensation in 2022 is largely because he didn't receive the large triennial stock grant this time. Base salary: $2 million Stock awards, bonuses, and perks: the rest of the total pay Security expenses: Alphabet spent $8.27 million ensuring his personal protection, a 22% rise over the prior year, due to his extensive global travel. Why the big dip compared to 2022 In 2022, Pichai received a massive $226 million stock award, part of Alphabet's once-every-three-years performance-based grant. This explains why his 2024 pay looks much lower. It's a reminder that top executive income often depends heavily on long‑term equity awards rather than annual salary. Building the wealth, bit by bit Pichai's wealth reflects consistent performance, strategic leadership during Alphabet's AI and cloud expansion, and steady stock appreciation. Though his 2024 paycheck was lower than peak years, that didn't affect the steady incline of his wealth over the years. Here's how: Equity stake: Though modest, his small share in a mega‑valued company grew significantly as Alphabet's stock soared. Smart stock sales: Over the past decade, he sold about $650 million worth of shares; if retained, those would now be worth well over $1 billion. Company growth: Alphabet's pivot toward AI and cloud pushed its market cap above $2 trillion, doubling investor returns and boosting Pichai's net worth. Where does he stand In 2024, some tech leaders earned far more: Apple's Tim Cook reportedly made $74.6 million, Netflix co-CEOs over $60 million, and Adobe's chief $52.4 million. At $10.7 million, Pichai's cash compensation is modest, though his net worth from Alphabet equity makes him a billionaire. In the realm of non-founding tech CEOs reaching billionaire status, he is joined by figures like Eric Schmidt. On the other hand, while Elon Musk, Mark Zuckerberg, Jeff Bezos, Larry Ellison, Larry Page, and Sergey Brin dominate global rich lists with net worths in the hundreds of billions, Pichai is not among the top 10 richest people in the world. Indeed, he does not appear in many top billionaire rankings, given his net worth is just over $1 billion, far below the threshold where most tech founders reside. However, Pichai's story speaks for a different arc altogether: While he sits far behind founder billionaires on global rich lists, he still shines among Indian-origin tech leaders in the US, a living example of how leadership, patience, and equity can build true wealth.

Why Nvidia is the biggest risk to the stock market—not tariffs
Nvidia has lost half its market value seven times since going public in 2000. While worries persist over the impact of shifting trade policy and higher tariffs on markets, the bigger risk may be the hundreds of billions invested in artificial U.S. stocks have forged new highs despite rising geopolitical risks. For Louis Gave, head of investment and research firm Gavekal, the worry is how dependent markets have become on AI spending—and one of its main beneficiaries, Nvidia. Since the release of ChatGPT in 2022, U.S. total market cap has expanded by $23 trillion—more than the market caps of Japan, Europe, and the U.K. combined, Gave wrote in a note to clients Monday. Though the capital spending on AI—about 11% of GDP—isn't as extreme as the tech boom in 1999, Gave sees parallels. Over seven years in the 1990s, capital spending rose from 8% to 11.5% of GDP. The consensus view had been that growth was structural and companies would have to buy computers and spend on broadband and e-commerce. But the spending did eventually stall, causing stocks to tumble. This time the surge in AI-oriented spending is shifting the traditionally asset-light businesses of Microsoft, Meta, and Alphabet into being asset heavy. Nvidia has been the biggest sees the possibility that the hundreds of billions of dollars invested in artificial intelligence turns out to be a dud as the bigger risk for markets. He posits the recent disappointment in semiconductor-equipment manufacturing stocks could foreshadow trouble ahead. While Tokyo Electron last week said the outlook for cutting-edge chips—such as Nvidia's—remained strong, Gave notes the company's warning that demand from logic manufacturers had markedly weakened. ASML in mid-July offered a similarly sober outlook and warned it couldn't guarantee 2026 growth amid tariff uncertainty. Gave sees a couple reasons behind these warnings, including the impact of higher tariffs and threats making Asian companies hesitant to spend billions of dollars when they are unsure if the rules of the game will change on them, Gave says. It is possible consumers could be rethinking spending, with Tokyo Electron noting softness in global sales of mobile phones, laptops, and personal computers. It could also be the semiconductor capex cycle is starting to feel the weight of the China embargo, Gave says. China has spent aggressively in recent years to build its own semiconductor supply chain and reduce its reliance on foreign inputs, but now in many subsectors, China is pushing ahead faster than most anticipated, Gave says. While the stocks of other companies have suffered, Nvidia has continued to forge higher. Gave is concerned what happens to the market when Nvidia, with its $4.2 trillion market cap, disappoints. He notes Nvidia has lost half its market value seven times since going public in 2000. The fallout from a repeat could be far-reaching. Gave notes the aggregate wealth of consumers everywhere has burgeoned amid the boom in large-cap tech, U.S. megacap stocks, crypto, and gold—and a not insignificant part of that wealth creation is reliant on the premise AI ushers in a new era of productivity gains. If those gains don't materialize or venture capital and big tech companies rethink the their expanding AI capital spending, Gave says the market could suffer a pullback in valuations that triggers a nasty negative wealth effect. It could also fuel investor concerns about what could replace AI as a driver for both earnings and economic growth. 'The recent rollover in what had been a strong momentum trade for the tech boom feels like it could be a proverbial canary in the coal mine," Gave cautions. Write to Reshma Kapadia at
