US futures rebounded despite a unanimous Federal Reserve rate hike, with Generac Holdings surging on a massive Amazon contract and Nebius Group raising GPU compute prices.

U.S. equity futures edged higher early Thursday following a unanimous decision by the Federal Reserve to raise interest rates by 25 basis points. This marks the first rate increase in three years, a move driven by persistent inflation pressures identified by Chair Kevin Warsh. As of 4:00 a.m. ET, Nasdaq futures climbed 0.9%, while S&P 500, Dow, and Russell 2000 futures all rose 0.7%. The market reaction occurred despite President Donald Trump’s sharp criticism of the board, which he labeled hostile and political, and his continued demand for 1% interest rates.

The Fed’s updated dot plot indicates that 16 of 18 officials project at least one additional 25-basis-point increase before year-end. Goldman Sachs suggests this could occur as early as October. Warsh defended the decision as necessary to remove accommodation from the economy. Retail sentiment on Stocktwits for major index ETFs such as SPY and QQQ remained bearish, highlighting a disconnect between institutional futures positioning and retail investor confidence in the current macro environment.

Generac Secures Billion-Dollar Amazon Deal

Generac Holdings (GNRC) shares surged 32% in early premarket trading after announcing a long-term supply agreement with Amazon. The contract is valued at up to $8 billion for backup generators specifically designed to power AI data centers. This development aligns with a broader legislative push in the House, where bipartisan legislation passed to mandate that large data-center operators cover the costs of required power-system upgrades. The move benefits energy infrastructure peers like Bloom Energy, FuelCell Energy, and GE Vernova, whose shares also rose in early trade.

Nebius Raises GPU Compute Pricing

Nebius Group (NBIS) saw its stock jump 8% in premarket hours following the announcement of a second major price hike for on-demand NVIDIA GPU compute services, effective October 1. This pricing adjustment comes as competitor Huawei announced two new advanced AI chips slated for 2027, along with broader interconnect solutions. Nvidia (NVDA) remains a central focus as these developments intensify competition in the AI hardware and cloud computing sectors, directly impacting the cost structures of companies relying on high-performance compute resources.

Software and Mobility Sector Moves

Snap Inc (SNAP) shares rose 3% after unveiling Specs Intelligence, a new AI assistant for its upcoming AR smart glasses. Salesforce (CRM) edged higher after presenting a fiscal 2030 revenue target of $63 billion at Dreamforce, a figure that significantly exceeded Wall Street expectations. In the mobility sector, Tesla (TSLA) faces speculation regarding a potential merger with SpaceX, fueled by comments from Ron Baron and Elon Musk’s emphasis on cross-company collaboration in AI and manufacturing ahead of the Roadster unveiling on October 1.

Fluence Energy (FLNC) plunged more than 15% in early premarket trading after slashing its FY26 revenue guidance by 20% due to ramp-up delays at its Houston manufacturing facility. Meanwhile, NIO Inc (NIO) fell toward its worst monthly performance of 2026 as retail investors feared dilution after CEO William Li reportedly ruled out share buybacks. These mixed results underscore the divergent operational challenges facing companies in the AI infrastructure, software, and electric vehicle sectors amid a tightening monetary policy environment.
