Linera Launches Babbage Testnet

May 1st — According to the Financial Times, U.S. stocks face multiple hidden risks despite the S&P 500 and Nasdaq notching fresh all-time highs recently. Valuations are at historic extremes. As of April 2026, the S&P 500’s trailing price-to-earnings (P/E) ratio stands around 24x (vs. a historical average of ~16x), while the Shiller cyclically adjusted P/E (CAPE) ratio has climbed to over 37x—second only to levels seen during the dot-com bubble. This mix of lofty valuations and sky-high expectations leaves the market with little margin of safety. Moreover, the current rally rests on optimistic assumptions: AI-fueled earnings growth, cooling inflation, falling interest rates, and contained risks. Any deviation from these assumptions could spark a broad market selloff.

May 1 — Nasdaq-listed cryptocurrency miner Riot Blockchain released its Q1 2026 financial and operational highlights today.

May 1 With Kevin Warsh expected to succeed Jerome Powell as Fed Chair next month, historical patterns suggest Bitcoin typically sees a few months of price correction after each new Fed chair takes office—followed by the start of a "true bull run." The market is closely watching whether this trend will hold, or if another dip is imminent. Meanwhile, the macro environment is sending mixed signals: former President Trump has already begun pushing for rate cuts. In an interview, Trump noted he’d be disappointed if Warsh doesn’t cut rates at the Fed’s first policy meeting under his tenure in June. Markets widely expect the Fed’s final meeting under Powell (this Wednesday) to leave rates unchanged. James Lavish, partner at Bitcoin Opportunity Fund, pointed out the Fed has added roughly $200 billion in U.S. Treasuries to its holdings over the past few months—signaling the official end of quantitative tightening (QT) and the start of "lightweight QE," a potential catalyst for risk ass
