The Revived Codex, Carrying OpenAI's Hopes for IPO

This article analyzes the intense recent development of OpenAI's Codex, positioning it as a crucial component for OpenAI's impending IPO. Over the past two months, Codex has seen a rapid series of major updates focused on integrating into real enterprise workflows. Key new features include enhanced context capture (Appshots, file previews, built-in browser), long-running task execution ("Goal Mode"), remote operation (phone control, lock-screen access), and enterprise management tools (plugin sharing, access tokens, automated risk review). These updates aim to make Codex a comprehensive AI workbench that can "see the scene, push tasks, and manage risks." The author argues that while ChatGPT proves OpenAI's massive user base and API provides foundational revenue, Codex represents OpenAI's clearest path to demonstrating tangible, high-value commercial viability. It targets developers and engineering teams—a segment already accustomed to paying for efficiency gains in costly software development cycles. This is critical because, despite higher overall revenue, OpenAI's adjusted operating margins remain deeply negative, highlighting the challenge of outrunning immense compute costs. The pressure is amplified by competitor Anthropic's success with Claude Code, which has shown that a focused approach on high-value enterprise and developer workflows can lead to a path toward profitability. Codex's aggressive evolution is thus seen as OpenAI's strategic move to capture a similar enterprise-ready, revenue-generating narrative essential for its market debut. In essence, "ChatGPT proved OpenAI has users. Codex needs to prove OpenAI is a business that can make money."

a16z: 7 Charts to Understand How Tokenization Is Changing the Nature of Assets

a16z: 7 Charts on How Tokenization is Transforming the Nature of Assets Tokenized Assets, often referred to as "real-world assets" (RWA), are altering the form, flow, and structure of the financial system. The market recently surpassed $30 billion (excluding stablecoins), driven largely by tokenized U.S. Treasuries. These offer investors digital, yield-bearing assets with efficient settlement. Growth varies significantly by asset class. Asset-backed credit leads in speed, followed by niche financial assets, while venture capital and active strategies took longer to scale. U.S. Treasuries and commodities dominate, holding about two-thirds of the current market share. Within commodities, gold tokenization dominates entirely due to its standardization and historical appeal in crypto. The ecosystem is spread across multiple blockchains. Ethereum holds over half the market, with others like BNB Chain, Solana, and Stellar holding significant shares. However, a key insight is that most tokenized assets currently lack "composability." While the total market is large, only a small fraction (e.g., 5% of tokenized bonds) is used within DeFi protocols. Many tokens are simply digital records of off-chain assets, not natively programmable financial building blocks. In contrast, smaller categories like reinsurance tokens see very high on-chain usage. Looking ahead, forecasts for the tokenized asset market by 2030 range from $2 trillion to over $30 trillion, representing immense potential growth from today's ~$340 billion base. Yet, relative to global markets (e.g., $140T+ in bonds), tokenization's penetration remains minuscule (<0.02%). The current phase focuses on digitizing straightforward assets for efficiency. The next major challenge is bringing more complex financial instruments on-chain and integrating tokenized assets into truly composable, internet-native financial infrastructure.

Data Theft at Will! Major Vulnerability Exposed in This Popular AI Programming Tool

A critical vulnerability in Anthropic's Claude Code AI programming tool allowed attackers to bypass its network sandbox for over five months, enabling potential data exfiltration. Independent researcher Aonan Guan discovered a second complete bypass exploiting a null-byte injection in the SOCKS5 proxy. This flaw, present since the sandbox's launch in October 2025, let processes inside the sandbox access any host, contrary to user-configured domain whitelists. The attack chain involved manipulating hostnames (e.g., `attacker.com\x00.google.com`). JavaScript's `endsWith()` check would pass `.google.com`, while the underlying C `getaddrinfo()` function would only parse `attacker.com` due to the null byte, creating a parser discrepancy. Combined with a previously disclosed prompt injection method, this could leak API keys, credentials, and internal data. Anthropic silently fixed the issue in April 2026 without a security advisory, CVE, or user notification. The researcher noted that Claude Code itself confirmed the vulnerability's severity when tested. This incident highlights broader industry issues, as similar vulnerabilities found in Google's Gemini CLI and GitHub's Copilot Agent also lacked public disclosures. The report criticizes the false sense of security created by a broken sandbox and emphasizes the need for defense-in-depth and transparency in AI tool security.

Under the squeeze between giants Tether and Circle, how can foreign exchange stablecoins break through?

In the face of dominance by Tether (USDT) and Circle (USDC), new entrants in the stablecoin space face significant challenges competing directly, especially in the foreign exchange (FX) market. A more viable and efficient path forward is the adoption of synthetic foreign exchange (Forex) built atop existing USD stablecoin rails. The rise of stablecoin neo-banks represents the next major growth area for mass crypto adoption, with FX becoming a core component. However, replicating the vast liquidity, distribution channels, and network effects of USDT/USDC is extremely difficult for new FX stablecoin issuers. The total market cap of all FX stablecoins is a fraction (roughly 1/700th) of USD stablecoins, leading to issues like poor liquidity, peg instability, limited acceptance, and complex compliance hurdles. Instead of issuing spot FX stablecoins, the article advocates for a model inspired by traditional finance's non-deliverable forwards (NDFs). Users would continue to hold underlying USDT/USDC, while their account balances are displayed and economically settled in their preferred local currency through MtM (Mark-to-Market) NDF structures. This approach leverages the deep liquidity and infrastructure of USD stablecoins while providing synthetic forex exposure. Key advantages include strong peg stability via oracles, retained access to USD stablecoin yields and liquidity, high capital efficiency, and easy scalability to new currencies. Primary use cases for this on-chain NDF forex include: 1. Neo-banks, custodians, and wallets offering multi-currency accounts to attract international users and increase deposits. 2. Forex carry trade strategies, potentially offering more stable and scalable yields compared to crypto-native products like Ethena. 3. Global corporate payments, allowing businesses to receive payments in local currencies while hedging forex risk on-chain, similar to services offered by Stripe in traditional finance. This synthetic forex model presents a pragmatic solution to overcome the network effects of incumbents and unlock the next wave of stablecoin utility for global consumers and businesses.
