On May 30, citing sources, Bloomberg reports that an Iranian ballistic missile struck a U.S. military base in Kuwait, leaving several American personnel with minor injuries and causing severe damage to two MQ-9 "Reaper" drones. Kuwait’s air defense system intercepted the incoming missile, but debris from the interception still impacted Ali Al-Saleem Air Base.

On May 30, BitMEX co-founder Arthur Hayes took to social media to share his bullish outlook for Hyperliquid’s ecosystem token HYPE, predicting the asset will hit $150. In his post, Hayes wrote: “HYPE to $150. Against Traditional Finance (TradFi), against the Clarity Act, long live Caesar.” HYPE has emerged as one of the strongest-performing mainstream crypto assets recently. Even as broader market pressure weighs on the crypto sector, HYPE has rallied nearly 20% over the past week, with public endorsements from several key industry figures. Notably, Intercontinental Exchange (ICE) CEO Jeffrey Sprecher previously praised Hyperliquid in public, stating its potential scale “may be larger than Nasdaq.” Driving HYPE’s continued prominence are two key catalysts: the U.S. is expected to approve its first batch of perpetual contract products for the asset soon, and market attention remains focused on progress regarding Grayscale’s Hyperliquid ETF. As a result, HYPE stands as one of the most

May 30 – xAI has been rolling out consistent updates to its AI coding tool Grok Build, and with the latest release at version 0.2.11, it’s added new features and performance optimizations, evolving rapidly from an early CLI tool to a full-fledged Agentic Coding environment. On the feature front, Grok Build now integrates X Platform and faster web search, plus new commands like /export, /login, /usage, and /config-agents.

May 30: Fueled by optimistic expectations of a potential U.S.-Iran ceasefire extension, U.S. stocks and oil markets rallied this week. The S&P 500 notched its ninth straight weekly gain, marking the longest weekly winning streak since 2023, while Brent crude held steady around $92 a barrel. Crypto markets, however, failed to track broader risk asset gains. Bitcoin dipped 2.6% to $73,445 over the past week, Ethereum dropped 2.5% to $2,011, Solana fell 2.2%, and TRX plummeted 5.6%—making it one of the weakest-performing top-10 tokens by market capitalization. Analysts cite cooling inflows into spot Bitcoin ETFs as a key headwind pressuring Bitcoin’s price. By contrast, some small and mid-cap tokens stood out. Hyperliquid’s native token HYPE surged 19.4% to roughly $65 this week, emerging as the market’s standout performer. The rally got a lift after Intercontinental Exchange (ICE) CEO Jeffrey Sprecher called Hyperliquid a “bigger opportunity than Nasdaq” at the Bernstein Conference

May 30 — Andrew Gault, founding partner of deep-tech investment firm 7percent Ventures and CEO of networking company ZeroTier, says the market is far too focused on quantum computing’s threat to Bitcoin wallet private keys, while overlooking a more imminent risk: encrypted communications data currently being transmitted between financial institutions. Gault points out attackers are employing a “collect now, decrypt later” strategy, mass-storing encrypted data such as interbank communications, payment authentication records, and digital signatures — waiting for future quantum computers with sufficient power to decode them. He argues the real danger lies not in static stored data, but in the daily authentication and signature info flowing between crypto exchanges, custodians, cross-chain bridges, and financial firms. In March, Google’s Quantum AI team released a study stating a fully capable future quantum computer could derive Bitcoin private keys from public keys in roughly 9 minutes
