The U.S. Treasury Department said it will purchase between $40 billion and $60 billion in long-term government debt in the first operation of its expanded repurchase program, demonstrating Secretary Bessent’s resolve to curb the recent rise in borrowing costs. U.S. Treasuries extended their earlier decline following the announcement, indicating the program’s size fell short of some investors’ expectations. The success of the expanded purchase program remains to be seen. After the program was first announced last month, yields fell before rebounding later. The benchmark 10-year yield hit its highest level since 2023 last week. Economist Guha, a former staffer at the New York Fed, noted: “The challenge always lies in whether the impact of these interventions can persist without larger fundamental changes.” Moreover, the maximum size of the repurchase operation does not mean the Treasury will necessarily purchase that amount of Treasuries. However, in repurchases targeting long-term nominal debt, the department typically buys the full amount; since the program was relaunched in 2024, it has only failed to do so in two of 52 such operations.

US President Donald Trump’s second son Eric Trump reposted a post about the meme coin LAPTOP’s sharp price crash after its launch, commenting: “Hunter should go back to painting.” His remarks target Hunter Biden, son of former US President Joe Biden, who launched the meme coin LAPTOP. The reposted post notes that LAPTOP plummeted 98% within minutes of going live, adding that the project had originally planned to allocate a portion of its tokens to users who incurred losses from TRUMP-related transactions.

Solana ecosystem full on-chain prediction market World announced that its independent platform World.xyz has officially launched, with over 1 million users on its waitlist. The platform offers thousands of markets spanning sports, cryptocurrency, politics, finance, economics, and culture, covering all NFL regular seasons, 7 soccer leagues, F1 races, the 2026 U.S. midterm elections, and Federal Reserve interest rate decisions. Since integrating Phantom in July, World has launched more than 150,000 markets. Each market on the platform consists of "Yes" and "No" contracts, priced between $0 and $1, and settled using Phantom’s U.S. dollar stablecoin CASH. Technically, World leverages Chainlink Data Streams and Chainlink Runtime Environment to provide market data and automated settlements, reducing manual intervention and dispute resolution wait times. Prediction markets for stock price movements, gold, silver, oil, natural gas, computing power, and weather will be rolled out sequentially.

Bubblemaps posted that profit and loss data for LAPTOP traders shows roughly 80% of participants are in the red, describing the token’s market performance as a "bloodbath". Specifically, two traders lost between $100,000 and $1 million, 100 lost over $10,000, 700 lost more than $1,000, and around 11,000 traders posted small losses. Bubblemaps did not further disclose the statistics’ time frame or the scope of the wallet sample used.

a16z Crypto has announced the release of a new version of its open-source zero-knowledge virtual machine (zkVM), Lattice Jolt. The update switches the underlying cryptography from elliptic curves to lattice cryptography, making the system quantum-resistant, and boosts both prover and verifier speeds by 2 to 3 times. Its proof size currently stands at under 100KB, which a16z Crypto claims is the smallest proof of any post-quantum zkVM. Lattice Jolt uses a novel polynomial commitment scheme called Akita, built on the Module-SIS lattice hardness assumption, with a target 128-bit security level. Akita was developed by LayerZero’s research and engineering team in collaboration with teams from Carnegie Mellon University, the University of Southern California, and a16z Crypto. Performance-wise, Lattice Jolt can prove over 2 million RISC-V cycles per second on a CPU-only device; with Apple Metal GPU acceleration, it exceeds 10 million cycles on a MacBook. The prover’s memory footprint has also dropped from roughly 300 bytes per cycle to 200 bytes, supporting proof generation for millions of compute cycles on mobile phones. The project will add additional zero-knowledge functionality via an upcoming academic paper.
