OpenAI is holding informal talks with Wall Street banks about a potential initial public offering in the fourth quarter of this year. 2026 is expected to be a blockbuster year for stock market debuts after a drought. Some on Wall Street are speculating that this year could be the biggest year ever for IPOs. OpenAI, Anthropic, and SpaceX are among the most closely watched tech companies that could go public.
An artificial lung system built by a team at Northwestern University successfully kept a critically ill patient alive long enough to enable a double lung transplant. The surgery involved temporarily replacing the patient's entire pulmonary system with a synthetic surrogate. The patient lived for two days without lungs. They received donor lungs after 48 hours, when their body was no longer suffering from sepsis. The patient has returned to a normal, independent life with excellent lung function.
Offline data sets don't work because robots never do exactly the same thing. These errors compound. Robots are hardware plus an algorithm, and hardware factors often matter more to task execution than the algorithm being used. Any real benchmark by necessity should look like a human competition. There are already early versions of such events, like the World Humanoid Games. However, major companies right now have too much to lose and too little to gain to bother competing.
Generative AI will make engineers better. While it may make the gap between the median and the max engineer shrink, the gap between the great and the best engineers is about to get much larger. The top engineers of the AI future will probably utilize a different skill set than the top engineers of today.
It's now possible to replace services with AI-generated code, if you know what you're doing. It's only going to get easier. SaaS businesses that don't give ongoing value are at risk of being replaced by customers. The ease of developing these tools will mean that buying and selling SaaS businesses will become less profitable.
Tesla's Q4 2025 earnings call made it clear that the company is no longer interested in being an automaker. The company has killed the Model S and Model X and has no plans for new mass-market models. It is pivoting entirely to 'transportation as a service'. Tesla will continue to focus on robotaxis, humanoid robots, and their supporting infrastructure, especially training compute.
Amazon's CEO, Andy Jassy, is leading negotiations with OpenAI CEO Sam Altman for an investment of up to $50 billion in OpenAI. The AI startup is seeking up to $100 billion in a funding round that could value it at up to $830 billion. Amazon has deep ties with Anthropic, one of OpenAI's competitors. It has invested $8 billion in Anthropic and is one of its key cloud providers. Amazon also developed an $11 billion data center campus for Anthropic.

Apple has acquired Q.ai, an Israeli startup that specializes in audio-focused AI, to advance features like whispered speech recognition and audio enhancement for products like AirPods and Vision Pro.
Amazon is negotiating a potential $50 billion investment in OpenAI, highlighting a strategic shift towards AI. Talks involve OpenAI CEO Sam Altman and Amazon's CEO Andy Jassy, with potential agreements including the use of Amazon's AI chips. This comes despite Amazon's prior investments in Anthropic, an OpenAI rival, and forms part of a broader $100 billion fundraising round spearheaded by OpenAI.
The finances of the GPT-5 bundle are worse than what Sam Altman and Dario Amodei suggest. Other labs are probably in a similar boat. However, AI models don't need to be profitable today, as long as companies can convince investors that they will be in the future. The sheer scale of value that AI could create is one reason to be really bullish about AI's long-run profitability.
OpenAI uses a bespoke in-house AI data agent that explores and reasons over its platform. It lets employees go from question to insight in minutes, allowing them to answer high-impact data questions. The agent was built specifically around OpenAI's data, permissions, and workflows. This post details how it was built to demonstrate how AI can support day-to-day work across teams. The tools used to build the AI data agent are available to all developers.
Some say Apple is behind on AI, while others say Apple is playing a different game. The gap between these two realities is where investment risk lives. Apple is likely building a moat where inference is free, privacy is structural, and the capex already happened when users bought the hardware. The next three years will tell us whether that's wisdom or complacency.
Microsoft's Q2 FY2026 earnings beat expectations across revenue, earnings per share, and Azure growth, yet the stock fell 11% after earnings. Demand is outpacing Microsoft's ability to build, so the company is accelerating its spending. Microsoft's commercial remaining performance obligation surged to $625 billion in Q2, with $281 billion coming from OpenAI, a substantial risk. Microsoft's strength indicates an insatiable demand for inference and increasing customer concentration risk for even the largest businesses in the world.
The winners in RL environments will be the teams that build real infrastructure. This has to be done in close partnership with frontier labs to industrialize replication training, verification, and long-horizon environment orchestration. There will likely be three to five significant winners. The market may end up resembling data labeling, which already has roughly three over-$1 billion-revenue players.

Building AIs that can do human-like philosophy could prove an especially subtle and hard-to-evaluate challenge. There are a variety of strategies that are now possible that could make real progress in the area. This essay looks at different angles of attack to help inspire efforts to tackle the change. Philosophy is hard, and solving it is likely to require some very sophisticated philosophical achievement.
GPT-4o, GPT-4.1, GPT-4.1 mini, and certain other older models will be retired on February 13 to streamline capabilities and transition users toward newer generations like GPT-5 and beyond. GPT-4o in ChatGPT had been restored after earlier deprecation due to user feedback, but the final retirement reflects broader adoption of more capable models. While the change affects the consumer ChatGPT experience, there are currently no simultaneous API changes, and developers relying on older models will be guided to migrate to newer alternatives as part of normal deprecation practices.

Moravec's paradox, an endlessly repeated aphorism that tasks that are hard for humans are easy for AI and vice versa, is really just a statement on what the AI community finds worthwhile to work on and doesn't have any predictive power about which problems are going to be easy or hard for AI.
ByteDance plans to release three AI models (a large language model, an image generation model, and a video generation model), and Alibaba plans to launch Qwen 3.5, a flagship AI model optimized for complex reasoning tasks.
The White House is convening a meeting between major crypto firms and traditional banks to address deadlock over digital asset market structure legislation that stalled earlier this month. The primary dispute centers on whether stablecoin issuers can offer interest-bearing features or rewards derived from reserve assets, with banks warning such products could trigger deposit flight from the traditional financial system. Wall Street institutions have successfully lobbied bipartisan lawmakers against allowing yield-generating stablecoin products, viewing them as a competitive threat, while crypto industry participants argue these features benefit end users. The White House crypto policy council and officials from the National Economic Council and Treasury aim to gather direct market feedback to resolve the impasse and advance the legislation.
Fidelity Investments is launching the Fidelity Digital Dollar (FIDD) in early February, marking one of the largest traditional financial institutions' entry into the stablecoin market. The stablecoin will be issued by Fidelity Digital Assets, a federally chartered bank, and operate on Ethereum with 1:1 dollar redeemability across Fidelity's platforms, major exchanges, and DeFi protocols for use cases including 24/7 institutional settlement and onchain payments. The launch was enabled by the recently passed GENIUS Act, which provides regulatory clarity for stablecoin reserves consisting of cash, cash equivalents, and short-term Treasuries with daily public disclosures and third-party attestations. Fidelity is entering into direct competition with Circle and Tether in the $308 billion stablecoin market, positioning FIDD as foundational infrastructure for expanding its onchain financial services ecosystem.
Wallet simulations currently depend on vulnerable RPC providers for state data. Deploying Merkle Patricia Trie proofs and multi-node consensus enables cryptographic prestate verification before execution. This trust-minimized architecture eliminates single points of failure, providing users with verifiable security when previewing transactions before signing.

Crypto is losing its position as the default destination for speculative capital, with AI attracting $35B in private investment in 2024 (up 8.5x from 2022) and robotics securing $2B in Q1 2025 alone, while institutional capital increasingly favors crypto equities and spot ETFs over altcoins. Stablecoins have emerged as the dominant use case with $304B in total supply (up 33% YoY), monthly volumes exceeding both PayPal and Visa, and stablecoin reserves now holding $133B in US Treasuries as the 19th largest holder. Value is migrating from infrastructure – which is commoditizing as data availability costs race to zero – to the application layer, with RWAs scaling rapidly from $15M in tokenized stocks in January 2025 to over $500M today, while equity perpetuals gain traction across multiple platforms.
Hyperliquid operates on a dual-chain architecture with HyperCore handling native trading execution (200,000 orders per second at 0.2 second latency via HyperBFT consensus) and HyperEVM supporting dApp development, including lending protocols, liquid staking derivatives, and yield strategies. The platform's vault system includes protocol-run HLP vaults for market making and liquidations, plus user vaults requiring leaders to maintain 5% stake and taking 10% of profits. HYPE tokenomics allocate 31% to a genesis airdrop across 94,000 users, 38.888% for future emissions, and 23.8% to core contributors with vesting through 2027-2028. HIP-3 introduces permissionless builder-deployed perpetuals, marking a significant step toward decentralizing the perpetual listing process beyond protocol control.
The stablecoin stack is fragmenting from full-stack issuers toward specialists (reserves, contracts, and onchain ops) and re-bundlers, but the biggest economic prize accrues to brands that own distribution because KYC/rails orchestration and payouts matter and scale buys leverage. Whoever re-bundles the money workflow will capture the most value.
Qash closed a $1.5 million pre-seed round led by Chaac Ventures with participation from Antler to scale its stablecoin-powered neobank. It was founded by Venezuelan-born Boris Spiwak to help Latin Americans save, spend, and invest in US dollars, with the new capital earmarked to expand product offerings, grow the team, and accelerate user acquisition amid rising stablecoin adoption after the GENIUS Act. Qash hopes to build on existing momentum as transaction volume has grown about 35x in six months.
