Project Prometheus, an AI laboratory co-founded by Jeff Bezos, has closed a funding round of €8.7 billion at a €33 billion valuation. Investors include JPMorgan and BlackRock. Bezos returns to an operational role alongside co-CEO Vikram Bajaj, a quantum physicist. The funding round was expanded from an initial €5.4 billion due to high demand. The company is headquartered in San Francisco with offices in London and Zürich. Unlike language-focused AI labs, Prometheus develops AI systems that understand physical laws for industrial applications, including materials research, fluid simulation and robotic manipulation. The company plans to establish a holding structure to acquire industrial companies that could benefit from its AI technology, following a Berkshire Hathaway-style model. The Zürich office positions Prometheus as a competitor for talent in the DACH region's engineering sector.
Pakistan signals return to global capital markets after four years. MG News | April 16, 2026 at 09:33 AM GMT+05:00 April 16, 2026 (MLN): Pakistan signaled its intention to return to international capital markets after a gap of around four years, with plans to issue rupee-linked, dollar-denominated instruments under its Global Medium-Term Note (GMTN) programme. The move comes as part of broader efforts to strengthen external financing, alongside preparations for the country's first Panda Bond issuance supported by agreements with multilateral lenders, according to a press release issued. Federal Minister for Finance and Revenue, Senator Muhammad Aurangzeb, shared these developments during a meeting with senior representatives of JP Morgan Chase on the sidelines of the World Bank-IMF Spring Meetings in Washington, D.C. He also briefed the delegation on counter-indemnity agreements signed with the Asian Development Bank (ADB) and the Asian Infrastructure Investment Bank (AIIB), expressed appreciation for financial support from the Kingdom of Saudi Arabia, and assured that the financing proposals and market options discussed would be carefully reviewed. In a separate engagement on the sidelines of the meetings, finance minister Aurangzeb held discussions with senior leadership of Franklin Templeton, where he said Pakistan would soon initiate requests for proposals (RFPs) to appoint lead managers for potential issuances under the GMTN programme. He emphasized that any return to global markets would be "selective" in pricing and timing, reflecting sensitivity to global interest rate trends and investor sentiment. The finance minister described the planned market re-entry as a potential turning point in Pakistan's external financing strategy, aimed at rebuilding investor confidence after a prolonged period of economic strain and reliance on bilateral and multilateral support. A successful issuance, he noted, could help diversify funding sources and signal improving macroeconomic stability. He also outlined progress on a broad privatization agenda, stating that nearly 30 state-owned enterprises have been transferred to the Privatization Commission. The government is advancing plans to outsource major airports, including those in Islamabad, Karachi, and Sialkot, and is exploring the sale of electricity distribution companies to improve efficiency and reduce fiscal pressures. Highlighting a shift in policy on digital assets, the minister confirmed the establishment of the Pakistan Virtual Assets Regulatory Authority (PVARA) and the issuance of No Objection Certificates to global platforms such as Binance. He added that the State Bank of Pakistan has withdrawn its 2018 restrictions on the use of banking channels for cryptocurrency transactions, indicating a more accommodative regulatory approach. The finance minister also expressed interest in collaborating with Franklin Templeton on capacity-building initiatives, including structured training programmes for officials from the Ministry of Finance and the State Bank of Pakistan, as part of efforts to strengthen institutional expertise in managing modern financial markets.
JPMorgan has reported strong first-quarter results, with earnings of $5.94 per share beating expectations and revenue reaching $50.5 billion, up nearly 10% year-on-year. The bank demonstrated balanced growth across its operations. Net interest income rose 9% to $25.5 billion, whilst noninterest revenue, including fees and trading, increased 11% to $25.1 billion. Credit quality remains solid, with provisions for losses at $2.5 billion, lower than the previous year, and charge-offs remaining flat. The bank recorded a small reserve build, though nothing indicating significant stress. Shares rose in premarket trading following the announcement.
America's largest banks reported strong first-quarter profits driven by robust investment banking activity and a resilient economy, though executives warned about mounting risks from rising energy prices and geopolitical uncertainty. JPMorgan Chase posted a profit of $16.49 billion, up 13% year-on-year, whilst Wells Fargo earned $5.25 billion and Citigroup reported $5.79 billion. Investment banking fees surged, with JPMorgan seeing a 30% jump and Citigroup a 12% increase in advisory fees, fuelled by market volatility and corporate dealmaking. However, JPMorgan CEO Jamie Dimon cautioned about "an increasingly complex set of risks", including wars, energy prices and trade tensions. Wells Fargo noted customers allocating more spending to petrol whilst cutting discretionary purchases, signalling potential downstream economic impacts from elevated oil prices.

The gains came amid market volatility and increased merger activity. However, JPMorgan CEO Jamie Dimon cited "an increasingly complex set of risks" including wars, energy prices and trade tensions. Wells Fargo's CFO noted consumers allocating more spending towards petrol whilst reducing discretionary purchases. Dimon warned that higher oil prices' impact "will likely take some time to materialise" if they persist.
