Fermi, a U.S. startup building a large AI-focused power campus in Amarillo, Texas, said co-founder and CEO Toby Neugebauer and CFO Miles Everson have left their executive roles, a disclosure that sent the stock tumbling on April 20, 2026. Shares fell roughly in the high-teens to low-twenties percent range after the company disclosed the changes; Reuters reported an intraday low of $5.03 and an about-18% decline. Neugebauer will remain on the board and Everson has been elected to the board, while Marius Haas was named chairman. The company created an interim “office of the CEO” led by two executives (including COO Jacobo Ortiz and Anna Bofa) and has engaged a search firm to find a permanent chief executive. Short seller Fuzzy Panda Research disclosed a new short position alleging improper transfers and misappropriation by executives. Fermi, which went public in 2025 and is backed by former U.S. Energy Secretary Rick Perry, is developing “Project Matador,” a proposed multi-gigawatt hybrid power site to serve AI data centers; the business has struggled to sign anchor tenants and its market value has fallen sharply since the IPO.

On April 20, 2026 California Attorney General Rob Bonta released newly unsealed court filings that allege Amazon.com used its marketplace leverage to pressure vendors and rival retailers into raising prices. The filing, part of a 2022 antitrust suit now more than three years old, cites dozens of examples involving brands such as Levi’s, Hanes, Scotts and Allergan (now part of AbbVie) and retailers including Walmart, Home Depot and Chewy. California says Amazon asked vendors to prod competitors to lift or restore prices, remove products from rival sites, or otherwise eliminate lower offers so Amazon would not have to undercut them. The state is seeking a preliminary injunction (hearing set for July 23) to halt the conduct while the case proceeds to trial, scheduled for January 19, 2027. Amazon has denied wrongdoing, calling the filing a distraction, and points to its claim of offering consistently low prices. The filing adds to other federal and state antitrust actions against the company and comes after Amazon surpassed Walmart in revenue in 2025.

On April 20, 2026, American Airlines publicly denied any interest in a merger with United Airlines, calling a combination “negative for competition and for consumers” and inconsistent with its understanding of the administration’s antitrust stance. The denial followed reporting that United CEO Scott Kirby had raised the idea with President Donald Trump in February. The statement helped trigger a selloff in American shares, which fell roughly 3–4% in pre-market and opening trading. Lawmakers signalled scrutiny: a bipartisan group of senators expressed concerns that a merger could reduce choice and raise fares. Regulators would face major antitrust questions if talks ever resumed. The controversy comes as U.S. carriers grapple with rising jet fuel costs amid Middle East tensions — oil topped about $88 a barrel on April 20 — and operational strains at key hubs such as Chicago O’Hare, where the FAA recently ordered capacity cuts for the summer. Analysts say the industry’s cost pressures could spur consolidation pressure, but any deal between two dominant U.S. network carriers would likely require divestitures and face intense regulatory review.

Bipartisan senators Elizabeth Warren and Mike Lee on April 19 sent a letter to United CEO Scott Kirby and American CEO Robert Isom seeking answers about reports the two carriers have discussed a possible merger, and asking they explain how consumers would be affected by May 3. The lawmakers warned a tie-up of the two “Big Four” carriers could control nearly half of the U.S. market, create the world’s largest airline by revenue, reduce competition, raise fares and fees, limit gate access for smaller rivals, cut routes from major hubs and suppress wages. The inquiry follows reports that Kirby floated the idea to President Donald Trump in February and recent comments from Transportation Secretary Sean Duffy about openness to large deals. American has said it is not engaged in merger talks; United declined to comment. Senators signalled such a deal would draw intense antitrust scrutiny from federal regulators and congressional panels and could prompt network and labor changes at major airports.

Gold prices slid on April 20, 2026, after renewed U.S.-Iran tensions pushed the U.S. dollar and oil prices higher, denting demand for the non-yielding safe-haven metal. Spot gold dropped roughly 0.3%-0.7% during the session to trade around $4,800 per ounce after hitting a one-week low, while U.S. June gold futures fell about 0.8%-1.4% to roughly $4,810-$4,840. Markets were rattled by reports that U.S. forces fired on and seized an Iranian cargo vessel and by Iran’s threat of retaliation and closure of the Strait of Hormuz, which sent oil up about 5%-7% and pushed 10-year U.S. Treasury yields higher. The stronger dollar and rising yields increased the opportunity cost of holding bullion, offsetting gold’s role as an inflation hedge. Other precious metals fell in sympathy, with silver, platinum and palladium slipping. Analysts warned that further escalation or prolonged disruptions to Gulf shipping could revive inflation expectations and keep interest rates elevated, weighing on bullion’s near-term recovery.

Victory Giant Technology, a Guangdong-based printed circuit board (PCB) maker that supplies AI server components including for Nvidia, jumped about 60% on its Hong Kong trading debut on April 21 after raising HK$20.12 billion (about US$2.6 billion). Shares opened at HK$330 versus an offer price of HK$209.88, peaked near HK$336.2 and were trading around HK$305 later in the session. The company exercised an upsizing option, selling 95.85 million shares (up from 83.35 million), with the retail tranche 431.15 times subscribed and the international tranche 18.5 times covered. Victory Giant reported rapid 2025 growth—revenue of ¥19.3 billion and net profit of ¥4.3 billion—and said nearly three-quarters of proceeds will fund mainland China production expansion. Cornerstone investors included CPE Rosewood, Janchor Fund and Yunfeng Capital. The deal was Hong Kong’s largest listing so far in 2026 and the biggest global IPO since a large European debut earlier this year, underscoring strong investor appetite for AI-linked industrial suppliers despite broader market volatility.
