Anthropic’s IPO boosts AI hype, with chip stocks leading the rebound, Bitcoin trading sideways amid volatility, and oil prices pulling back.

Overnight to early this morning, Anthropic filed for an IPO, reigniting short-term AI hype in the market. The Philadelphia Semiconductor Index rose around 3% in a single day, driving the S&P 500 up 0.70% and the Nasdaq up 0.82%, both ending their two-day losing streak. On the other hand, ahead of the Federal Reserve's policy decision, the U.S. Treasury market remained calm. Oil prices edged lower, but Middle East risk premiums persisted. Additionally, market turmoil in Brazil has drawn global attention. With Lula's surprise election victory, Brazil's stock market, bonds, and the real all slumped simultaneously; multiple stocks dropped over 30% in a single session, with some falling more than 50%. Investors worry the new government will expand fiscal spending, stoking inflation expectations, leading to a sharp spike in Brazil's 5-year credit default swap (CDS) spreads. For equities, per data from BIT Stock Platform, star stock Nvidia rose 2.4%, Micron gained 2.98%. CoreWeave reversed its pre-market decline to close up 1.76%. The optical communications sector stayed strong: LITE rose over 8%, AAOI over 6%. Neocloud, which was bearish on by Musk, showed relative resilience; only NBIS fell 3.48%, while other major stocks closed higher. The storage sector was flat: SNDK rose 1.42%. Crypto-related stocks fell broadly: MSTR dropped 4.21%, the previously standout NEAR Treasury Company fell 10.48%, BMNR down 6.52%, CRCL down 7.07%. Separately, per HTX market data, ahead of the Federal Reserve's interest rate decision, market sentiment was cautious, with Bitcoin trading in the $80,000 range, currently at $80,094.20.
