Melbourne-based fleet management firm Netstar Australia has been hit by the Blackshrantac ransomware group in a data extortion attack, underscoring rising cyber risks in the telematics sector that handles sensitive GPS data for government and critical infrastructure operators.
The Rhysida ransomware group has targeted Harbour Town Doctors, a Queensland medical centre, threatening to leak sensitive patient data. The attack highlights the persistent threat of ransomware to the Australian healthcare sector.
One of the largest lead generation datasets ever compiled has been found exposed online, containing 4.3 billion professional records in a 16 terabyte unsecured database.
Nvidia’s Earnings Spark AI Debate as Investors Question Long-Term Value
Nvidia’s earnings highlight its AI dominance, yet an 8% stock drop signals investor jitters over tariffs, DeepSeek’s rival GPUs, and soaring costs. Despite record revenue and surging Blackwell demand, Wall Street demands proof beyond the hype in a rapidly shifting market.
Thursday’s selloff highlighted a growing concern that, while Nvidia’s latest earnings were undeniably impressive, they weren’t quite enough to sustain the recent wave of AI enthusiasm. The company’s shares initially climbed on stronger-than-expected revenue—driven by surging demand for Blackwell GPUs and strategic AI partnerships. But eventually slid 8% as investors worried about escalating costs, possible challenges from DeepSeek’s rival technology, and President Trump’s renewed tariff threats.

Still, eMarketer technology analyst Jacob Bourne sees plenty of upside, noting,
“Nvidia’s results reaffirm that it continues to lead the AI landscape, sidelining skeptics.”

Thursday’s broader market downturn underscored how quickly excitement can fade for AI-focused firms. Super Micro Computer, which narrowly averted a Nasdaq delisting, sank 16%. Nuclear power provider Vistra, despite delivering a solid earnings report, dropped 11%. Palantir, a heavyweight in enterprise AI, gave up 5%. As market sentiment weakened, President Trump’s administration ratcheted up pressure on China’s semiconductor ambitions, reportedly meeting with Japanese and Dutch officials to explore tighter curbs on the transfer of advanced chipmaking technology.
This push toward restricting China’s progress is especially concerning for Nvidia, which once depended on Chinese customers for up to 25% of its data center revenue.
Looming tariffs on TSMC-manufactured chips add another layer of tension, just as Nvidia ramps up production of its advanced Blackwell line. DeepSeek’s claims of matching Nvidia’s performance on cheaper, older GPUs have further fueled debate over whether premium hardware can remain unchallenged in a rapidly evolving sector. Though Nvidia’s leadership in AI hardware seems secure for now, these combined forces underscore just how delicate that position can be.
Nvidia’s robust fundamentals and record-breaking revenue continue to validate the company’s stature as an AI powerhouse, but a variety of factors will test that status in the coming months.
Investors have been rethinking whether sky-high valuations are justified in a market increasingly shaped by protectionism and wavering consumer sentiment. Nvidia’s leadership in advanced machine learning seems secure for now, particularly for complex “reasoning” AI models that require top-tier hardware.
Wall Street wants more than just forward-looking optimism—they’re demanding clarity on how Nvidia will handle shifting trade policies, looming tariffs, and emerging competitive threats. But analysts point to potential competition from budget-friendly solutions that handle many workloads just well enough.

While Nvidia CEO Jensen Huang exudes unwavering confidence that Blackwell will redefine the AI landscape, Thursday’s market rout revealed that investors want more than just a shiny sales pitch. With tariffs looming and cutthroat competition on the rise, Wall Street is demanding proof that all these grand AI experiments can actually deliver.
Earlier this week, talk shifted to OpenAI’s rumored pivot toward SoftBank’s “Stargate” project, a move that signals the AI infrastructure game is only getting hotter. Although Nvidia isn’t part of that realignment, the hint of diversifying compute partnerships could shake up an industry where premium pricing and reliance on hyperscalers have historically played in Team Nvidia’s favor—especially as inference costs surpass the once-dominant training expenses.
Nvidia’s earnings certainly make for blockbuster reading and confirm the company’s commanding role in AI. Yet the stock’s jittery response suggests that market watchers aren’t as thrilled about open-ended R&D budgets as they used to be. To keep its share price on an upward trajectory, Nvidia will have to tackle DeepSeek’s disruptive claims head-on, address any margin pinch around Blackwell, and look beyond its usual set of hyperscaler clients. Efficiency is now the name of the game, and investors are sniffing out any sign of runaway spending.
There’s no denying that this chip titan’s jaw-dropping numbers underscore its formidable position, but Wall Street’s collective raised eyebrow hints that not everyone is buying into Nvidia’s $3 trillion market cap as the dawn of a new era. Instead, skeptics see it as a possible omen that today’s AI enthusiasm could be tomorrow’s big letdown. Whether Nvidia sails through these challenges like a seasoned captain of industry or hits choppy waters remains to be seen, but the world is certainly watching every GPU-powered move.

By 2027 the race to become the first cosmic CEO is moving from science fiction to strategy. Starcloud has already trained an AI model in orbit on an Nvidia H100, while Google prepares Project Suncatcher. What remains missing is not ambition, but clear pricing and proof orbital compute can pay.
Oracle has become a test of how much debt markets will tolerate in the AI buildout. Rising credit costs and growing use of swaps show investors backing the AI story while seeking protection in case promised workloads and cash flows fail to arrive on time.
NVIDIA’s staggering 57 billion quarter didn’t just calm the market, it rewrote the AI story. What looked like a bubble unwind now looks like a misread. With sovereign AI deals, a Saudi megacentre and a global capex surge, NVIDIA has reset the race and reminded investors this era is only beginning.
NVIDIA’s blockbuster quarter has reset the AI narrative, turning fears of a bursting tech bubble into renewed conviction in a structural shift. With record data-centre sales and sold-out Blackwell GPUs, NVIDIA now looks less like a chip stock and more like core AI infrastructure in the AI build-out
