Cerebras Nearly Collapsed Burning $8M Monthly Before $60B AI Chip IPO
Cerebras Systems, now valued at $60B after its 2026 IPO, nearly went under in its early years while burning $8 million a month developing what many considered an impossible chip. The company's survival hinged on a pivot to wafer-scale AI chips, which eventually revolutionized AI computing.
Cerebras Systems, which recently became the biggest tech IPO of 2026 with a $60 billion valuation, nearly collapsed in its early years while burning through $8 million a month. The company was developing a chip that many industry experts believed was impossible to build. At one point, Cerebras had only a few months of runway left before running out of cash entirely.
The chip in question was the Wafer-Scale Engine (WSE), a massive processor the size of a dinner plate that contained 1.2 trillion transistors. Traditional chip manufacturing produces multiple chips from a single silicon wafer, but Cerebras aimed to use the entire wafer as one giant chip. This approach required solving enormous technical challenges, including heat dissipation, manufacturing defects, and power delivery across the wafer.
Cerebras's breakthrough came when it developed a redundant architecture that could route around defective areas on the wafer, allowing the chip to function despite inevitable manufacturing imperfections. The company also designed a sophisticated cooling system using water channels embedded directly into the chip package. These innovations made the WSE viable for AI workloads that required massive parallel processing.
The company's survival was secured by a combination of strategic pivots and key investors who believed in the vision. Cerebras initially targeted scientific computing but later repositioned itself for AI training and inference, which proved to be a much larger market. The company also secured crucial funding rounds from investors like Benchmark Capital and Coatue Management.
Cerebras's wafer-scale chips are now used by major AI labs, including national laboratories and large enterprises. The chips excel at training large language models and running inference for applications like drug discovery and climate modeling. Compared to traditional GPU clusters, Cerebras systems offer lower latency and higher throughput for certain workloads.
The IPO was a landmark event for the AI hardware industry, demonstrating that alternative chip architectures could compete with Nvidia's dominant GPUs. Cerebras's success has also validated the wafer-scale approach, prompting other chipmakers to explore similar designs. The company now faces the challenge of scaling production to meet surging demand.
For users and enterprises, Cerebras's chips are not sold directly but through cloud services like Cerebras Cloud and partnerships with data center operators. Pricing is not publicly disclosed but is typically based on compute time or subscription models. The chips are available in select regions, primarily in the United States and Europe, with expansion plans for Asia.
Despite its success, Cerebras faces ongoing challenges, including competition from Nvidia's next-generation architectures and the need to continuously improve its software stack. The company is also exploring new applications in edge computing and autonomous systems. Industry watchers expect Cerebras to announce its next-generation WSE within the next year.
Nvidia Earnings and Retail Reports Set to Test Market Rally This Week
Investors await Nvidia's quarterly earnings to gauge AI demand, while Walmart and other retailers report on consumer spending amid inflation. The results will shape market direction as stocks hover near record highs.
Stock markets are scaling new peaks, but the coming week could determine whether the rally has legs. All eyes are on Nvidia's earnings report, scheduled for Wednesday, which will provide a critical litmus test for the artificial intelligence boom that has powered much of the market's gains. Meanwhile, major retailers including Walmart, Target, and Home Depot are set to release quarterly results, offering insights into consumer behavior as inflation persists and interest rates remain elevated.
Nvidia, the chipmaker at the heart of the AI revolution, is expected to report another blockbuster quarter. Analysts project revenue growth of over 100% year-over-year, driven by insatiable demand for its graphics processing units used in data centers and AI applications. The company's guidance will be closely scrutinized for signs that the AI spending spree by tech giants like Microsoft and Meta is sustainable. Any disappointment could trigger a sharp sell-off in tech stocks, which have led the broader market higher.
Retail earnings will paint a picture of the American consumer, who has remained resilient despite higher prices and borrowing costs. Walmart, the largest U.S. retailer, is expected to show steady sales growth, though margins may be squeezed by inflation and theft. Target and Home Depot will provide updates on discretionary spending, which has softened as households shift to essentials. These reports come amid mixed economic data, with strong job growth but cooling retail sales in recent months.
The confluence of tech and consumer data makes this week pivotal for market sentiment. If Nvidia delivers a strong report and retailers hold up, it could reinforce the narrative of a soft landing for the economy. Conversely, weak results could revive fears of a slowdown or excessive AI hype. The Federal Reserve's minutes from its last meeting, due Wednesday, will also be parsed for clues on interest rate policy.
For investors, the stakes are high. The S&P 500 is up nearly 20% in 2024, with Nvidia alone accounting for a significant portion of that gain. A stumble from the chipmaker could expose the market's concentration risk, where a handful of mega-cap stocks drive most returns. Retailers, on the other hand, represent the broader economy and could signal whether consumers are finally buckling under pressure.
Beyond the numbers, these reports will shape sector rotation. Strength in AI could boost tech and semiconductor ETFs, while weak retail data might favor defensive sectors like utilities and healthcare. International markets are also watching, as Nvidia's supply chain ties to Asia and Europe mean its performance has global implications.
Uncertainty remains high heading into the week. Options markets are pricing in a potential 10% swing in Nvidia's stock after earnings, reflecting the binary nature of the event. For retailers, inventory levels and holiday season outlooks will be key. Any surprises—positive or negative—could set the tone for trading into September, a historically volatile month for stocks.

Jailbreaking Older Kindles Gains Popularity After Amazon Ends Support
With Amazon ending support for several older Kindle models, users are increasingly turning to jailbreaking to keep their devices functional. While this allows continued book transfers, it carries significant risks including security vulnerabilities and voided warranties.
A growing number of Kindle owners are resorting to jailbreaking their older e-readers after Amazon officially ended software support for several models. The move comes as the company focuses on its newer devices, leaving users of older Kindles without crucial updates and security patches. Jailbreaking, a process that removes manufacturer-imposed restrictions, allows these users to continue adding books to their devices through alternative methods. However, this workaround is not without its dangers, including potential security risks and the voiding of any remaining warranty.
The jailbreaking process typically involves exploiting vulnerabilities in the Kindle's firmware to gain root access. Once jailbroken, users can install custom software, modify system files, and bypass Amazon's DRM protections. This enables them to sideload books from other sources, such as library apps or independent publishers, without relying on Amazon's ecosystem. However, the technical complexity varies by model and firmware version, and not all Kindles can be jailbroken. Older models like the Kindle Keyboard and Kindle Touch are particularly popular targets due to their simpler software.
Amazon's decision to end support stems from its strategy to push users toward newer devices like the Kindle Paperwhite and Oasis, which offer better displays, faster performance, and longer battery life. The company argues that older hardware cannot handle the latest features and security standards. Yet many users feel their aging devices still serve their primary function—reading—and are reluctant to upgrade. This has created a niche community of tinkerers who share jailbreak guides and custom tools on forums like Reddit and MobileRead.
The primary risk of jailbreaking is security: modified firmware may contain vulnerabilities that malicious actors could exploit. Additionally, jailbroken Kindles cannot receive official updates, meaning any future security flaws remain unpatched. Amazon also warns that jailbreaking violates its terms of service, potentially leading to account bans or loss of access to the Kindle Store. For users who primarily read Amazon-purchased books, jailbreaking may not be worth the hassle, as they can still download books via USB or use the Send to Kindle feature on newer models.
For those determined to keep their older Kindles alive, the process begins with checking compatibility. Devices on firmware version 5.13.3 or earlier are generally easier to jailbreak, while newer versions have patched known exploits. Users must back up their data and proceed carefully, as a failed jailbreak can brick the device. Once successful, they can install tools like KOReader or Calibre to manage books from various sources. However, battery life and performance may degrade over time due to unofficial software.
The impact is most pronounced in regions where newer Kindles are expensive or hard to obtain. In developing countries, older models remain in widespread use, and jailbreaking offers a cost-effective way to keep them functional. Amazon has not commented on the trend, but its aggressive push for upgrades suggests it may not actively combat jailbreaking as long as it does not affect its core business. Meanwhile, the community continues to develop new methods, with some users even porting Linux to older Kindles for added functionality.
Looking ahead, the future of jailbroken Kindles remains uncertain. As Amazon releases newer firmware versions, exploits become harder to find, and the pool of vulnerable devices shrinks. Some experts predict that eventually, all older Kindles will become unusable as battery cells degrade and cloud services shut down. For now, though, the jailbreak community offers a lifeline for those who refuse to let their beloved e-readers go quietly into the night.
