CBS: U.S. Treasury Secretary and Trump Once Had Heated Debate on Tariff Policy

Beating AI News Flash: OpenAI Codex Product Lead Tibo has issued an update addressing recent quality complaints from Astra users, stating the team has identified and fixed multiple defects and will perform a reset by midnight local time (12 PM Beijing Time). Tibo noted that after collaborating with some users, the team confirmed and resolved the following issues: 1) Old model skill triggering anomalies: Skills built for previous models were triggering too frequently, or preventing the model from reviewing its own work. 2) Context management experiment disabled: An optional context management experiment could cause premature termination or outdated message responses, and has now been turned off. Rough estimates indicate approximately 4,000 to 5,000 users were affected by this experiment. 3) Misconfigured engines removed: Some engines were improperly set up, leading to measurable quality declines in tail-end traffic flowing through them, and have now been removed. Additionally, the team has made several minor improvements, saying the overall experience should see noticeable enhancements, including more consistent execution, more accurate tracking of users’ latest messages, and better result checks during workflow progression.

According to a Wall Street Journal report, a group of 19 interconnected Polymarket accounts placed concentrated bets on the financial results of KPMG-audited listed companies over the past several months. Of the 42 trades, 41 were profitable, delivering a 98% win rate and cumulative gains of roughly $22,000. Bubblemaps analysis revealed these accounts had previously wagered on 18 KPMG clients including Wells Fargo, Home Depot, DoorDash, and General Mills, with funds flowing in complex patterns between the 19 accounts, sparking suspicion they were controlled by the same individual or team. Notably, this development comes as U.S. law enforcement probes a KPMG employee suspected of insider trading via Polymarket. The WSJ previously reported the employee is under investigation for betting on whether listed companies’ quarterly results would beat market expectations. It remains unconfirmed whether the identified account group is linked to this employee, and Bubblemaps stressed that its analysis alone does not prove insider trading. KPMG said it has "zero tolerance" for trading using non-public client information and has strengthened relevant monitoring. As the prediction market expands rapidly, insider trading risks on Polymarket are drawing sustained attention from regulators and law enforcement.

According to GMGN market data, Robinhood ecosystem meme coin CATGPT briefly surged past $17 million in market capitalization, hitting an all-time high, and has since pulled back to $15.3 million. Its trading volume reached $5 million in the first three hours post-launch. CATGPT is traded in pairs with OPENAIx1L (OPENAI 1x Long tokenized position) via the Long.xyz platform. Long.xyz is a meme coin launch platform on Robinhood Chain, focusing on the innovative "crypto-stock meme" model, which directly links traditional meme coins with tokenized U.S. stocks, forming a dual-driven mechanism of "sentiment speculation + real asset anchoring". The platform allows users to issue meme tokens and pair them directly with on-chain U.S. stock tokens (such as NVDA, TSLA, AAPL, etc.), rather than pairing with traditional assets like USDT or ETH. A portion of transaction fees flows back to the community treasury to accumulate the corresponding U.S. stock tokens, creating a unique value capture model. OPENAI currently has high IPO expectations, but as it remains unlisted, traditional markets do not offer direct long opportunities. On-chain platforms like this provide speculative exposure through such tokenized long positions paired with meme coins, an upgraded iteration of the earlier model where stock tokens like NVDA were paired with meme coins. BlockBeats reminds users that related tokens are highly volatile and carry significant uncertainty, urging investors to exercise caution.

According to monitoring by Ai Yi, renowned trader @XXAntiWar closed two positions on Hyperliquid today, extending his perfect 100% win rate. He closed 4.7654 million PONS long positions worth approximately $2.943 million, generating a profit of around $87,000. Separately, he closed 3,478.95 ZEC short positions valued at roughly $4.078 million, earning an additional $27,000. The two trades combined yielded a total profit of about $114,000. The day prior, he had already pocketed roughly $660,000 from ZEC short positions. Ai Yi stated that since his recent return to trading, XXAntiWar has accumulated a total profit of approximately $774,000 on Hyperliquid. Additionally, another of his wallet addresses recently deposited around $2 million in margin, likely to open new trading positions.

CNBC crypto commentator Ran Neuner stated that regulatory uncertainty is the biggest risk currently facing Hyperliquid. Regulators have begun establishing regulatory frameworks for centralized crypto exchanges, and the next step may expand oversight to decentralized exchanges (DEXes), with significant ambiguity remaining over how to handle decentralized perpetual contract platforms like Hyperliquid. However, Neuner also noted that Hyperliquid has built strong network effects and liquidity advantages, making it difficult for competitors to replicate its technology alone to challenge its market position. Exchanges typically draw capital and users to markets with the deepest liquidity, so "the network is irreplicable". Hyperliquid remains the leading decentralized perpetual contract platform, with approximately $223 billion in trading volume over the past 30 days. Separately, the U.S. has signaled its willingness to establish a compliance path for Hyperliquid to enter the U.S. market, though no specific regulatory framework has been announced to date.

Cross-chain liquidity protocol Symbiosis announced that around 04:28 UTC on September 11, its Bitcoin bridge was attacked, with the perpetrator exploiting a vulnerability. BTC-related routes have been suspended. Symbiosis clarified that the incident only impacted the Bitcoin Bridge; the affected system has been isolated from other components, while other cross-chain routes (including EVM chains, TRON, TON) and Octopools remain unharmed and operational. The team has recovered roughly 15 BTC, now held in a multi-sig wallet controlled by the team. For the stolen funds, Symbiosis has issued a 20% white hat bounty to the attacker, with a deadline of September 13. If the attacker fails to return the funds, an equal proportion bounty will be offered to anyone who can assist in recovering the assets. The final loss amount is still being tallied, and the team will contact affected liquidity providers individually to develop a compensation plan. Separately, on-chain security monitoring firms noted that the incident involved Symbiosis BridgeV2 abnormally minting syBTC, leading to approximately $336,000 in WBTC losses; the relevant vulnerability is currently being resolved.
