MOST POWERFUL OBESITY DRUG YET: PEOPLE LOST UP TO 25% OF WEIGHT IN TRIAL

Late-stage clinical trial data on the obesity drug retatrutide showed an average loss of 25% of body weight after 90 weeks. More than a third of the participants taking the drug in the trial lost 30% or more of their weight. The drug also helped reduce knee pain and sleep apnea events, and it improved cardiometabolic measurements across the board. At the start of the trial, more than a third of trial participants had prediabetes - the condition had resolved in more than 90% of those participants by the end.

COMMIT DESCRIPTION AS A THINKING TOOL

Writing a commit description can help you reflect on the changes that AI made. It also serves as a way to check if everything is as intended. Being able to explain why you are shipping something will help you explain or fix it if it breaks later. AI can do the work - writing why is where you find out whether you understand what you are shipping.

DEEPSEEK BUILDS FOR HUAWEI ASCEND

DeepSeek plans to start rebuilding the software ecosystem around Nvidia's hardware so that Chinese chips become genuinely easier to use and capable of training frontier AI models. Nvidia's CUDA ecosystem provides developers with a mature set of tools for writing programs, optimizing performance, and getting thousands of GPUs to work together efficiently. DeepSeek is trying to create a layer of abstraction between models and the underlying GPU hardware that could potentially sit on top of either Nvidia GPUs or Huawei Ascend chips. If all goes well, the cost and difficulty of moving AI workloads from Nvidia to Chinese AI hardware could fall significantly.

GENERALIZATION DYNAMICS OF LM PRE-TRAINING

During pre-training, models can abruptly switch response patterns, a phenomenon termed MODE-HOPPING. Tests reveal this behavior in OLMo3-32B during arithmetic tasks, showing sudden shifts between pattern-following and correct task inference as training progresses. Controlled experiments suggest competing shallow and generalizable circuits within models, revealing that longer training doesn't always guarantee better generalization.

A NEW TRANSFORMER PASSES ITS HIDDEN STATE TO THE NEXT TOKEN INSTEAD OF RECOMPUTING IT

Researchers built LIFT, a transformer that feeds its internal state back into the next generation step instead of squeezing everything through the single token it outputs. Training stays parallel because the states come precomputed from an off-the-shelf model's next-token predictions, while at inference the model feeds back its own. LIFT models from 135M to 1B parameters beat token-matched standard transformers on language modeling, reasoning, and procedural tasks, so the next question is whether the gains hold at frontier scale.

KALSHI TO END LIQUIDITY INCENTIVE PROGRAM AMID WASH TRADING ALLEGATIONS

Kalshi told the CFTC it plans to end its Volume Incentive Program, which paid traders for boosting liquidity, no earlier than October 13. The decision follows reports that the CFTC was examining trades after allegations that repeated $5,500 trades inflated ether perpetual futures volume by more than $5 billion over the past month, though Kalshi says it is not under investigation and attributes the repeated prints to market makers posting fixed quotes that faster traders hit. Kalshi's monthly volume still hit an all-time high of $52.98 billion in September as of September 29, and Ark Invest announced it now holds direct exposure to Kalshi through ARKK, ARKW, and ARKF, while Reuters reported Kalshi is in advanced talks to raise about $1 billion at a $40 billion valuation.

EL SALVADOR LAUNCHES STABLECOIN APP ON BASE

Five years after mandating Bitcoin as legal tender, El Salvador is pivoting to stablecoins after BTC saw limited traction as a payment medium. The government is launching a digital dollar app built on Coinbase's Base network, targeting the remittance corridor where price stability matters more than the volatility Bitcoin carries. Remittances account for about 25% of El Salvador's GDP, making this a concrete test of whether stablecoin infrastructure can succeed where the BTC legal tender experiment stalled.

COMPUTE SOVEREIGNTY AND PROGRAMMABLE MARKETS

Simple Compute Market (SCM) introduces open-source infrastructure for programmable compute markets where sellers run sovereign storefronts, buyers negotiate prices peer-to-peer with seller nodes, and listings propagate through federated registries rather than a single controlled platform. The protocol unbundles roles that centralized marketplaces combine, enabling independent operators to run registries, storefronts, settlement services, and fulfillment systems while sharing interfaces that keep them interoperable. This design reduces compute dependency risk: high switching costs from opaque discovery and bespoke negotiation transform suppliers into structural lock-ins rather than interchangeable vendors. Arkhai is building an optional managed service layer on top of SCM while keeping the core protocol open source.

BLOCKCHAINS CREATE NET NEW MARKETS

For most of financial history, new markets were constrained by listing committees, legal frameworks, and geographic fragmentation, which throttled how fast new risk units and instruments could emerge. Blockchains remove both constraints by making issuance permissionless and distribution global, and every major crypto category, from perps and spot DEXs to prediction markets and tokenized physicals, reflects value accruing to whoever controls issuance and exchange of net new markets. Hyperliquid exemplifies the dynamic: HIP-3 and HIP-4 let users launch derivatives on a shared global venue, onchain RWA perps reached a $1.4T annualized run-rate in July, and WTI found price discovery on trade.xyz during an oil shock while CME was closed. The addressable universe extends beyond existing assets to any risk that can be oracled and made two-sided, pointing toward expansion into compute futures, macro indicator perps, and markets that traditional finance never listed.

THE PRIVACY CABAL HAS GONE ALL IN ON QUANTUM

Quantus, launched September 9, is a proof-of-work chain that mirrors Bitcoin's 21-million-coin monetary policy while replacing ECDSA with ML-DSA lattice-based signatures (NIST FIPS 204) and adding Zcash-style shielded addresses. The project raised $2.42 million across two rounds at a $100 million valuation, with Balaji leading the second round and Naval Ravikant's fund and AngelList co-founder Babak Nivi also participating. The quantum risk thesis has grown specific: Google reduced the Bitcoin elliptic curve attack to under 1,200 logical qubits in March, NIST will deprecate elliptic curve signatures after 2030, and 6.04 million BTC (~30% of supply) sit in addresses with already-exposed public keys that BIP-360 cannot protect without a coin migration. The circulating market cap is about $2 million against a $1.26 billion FDV, with 73% of coins not yet mined and 26% locked by contract until September 2027.

WHAT HAPPENS WHEN STOCKS BECOME PROGRAMMABLE?

Tokenized stocks like xStocks operate as fully collateralized tracker certificates rather than direct equity, giving holders price exposure without shareholder voting rights. The price peg relies on authorized institutions arbitraging between underlying shares and tokens. On weekends when stock markets are closed, hedging constraints cause spreads to widen. Onchain equities unlock DeFi composability: existing lending protocols like Kamino accept selected xStocks as USDC borrowing collateral, and stock tokens can settle atomically against stablecoins in a single transaction. Developers can reuse existing wallet infrastructure and smart contracts to build thematic indices, structured products, and cross-protocol collateral tools on top of these assets.
