Equity Markets

US equities extended their longest weekly winning streak since 2023, with the S&P 500 climbing to fresh records after Brent crude fell 19% in May—the steepest monthly drop since 2020. Ford Motor Co. raced toward its best monthly gain in 17 years as investors priced in the automaker's potential exposure to artificial intelligence infrastructure spending, while Dell Technologies surged 150% after securing Pentagon data-center contracts. The rally reflects growing conviction that AI investments will sustain corporate earnings growth, though Anthropic's $900 billion valuation—which now exceeds OpenAI—has sparked debate over whether public market investors can access similar returns. European equities faced mounting pressure from cheap Chinese imports, with policymakers searching for solutions as trade tensions escalate between Brussels and Beijing.

OpenAI engaged Citigroup and JPMorgan Chase about joining its banking syndicate for a potential public offering, signaling Wall Street's eagerness to participate in what could become the largest AI IPO. The sector's momentum showed signs of moderating despite the S&P 500 returning to record highs, with some strategists arguing that easy money has already been made in the two-month rally. Meanwhile, a famous math problem stumping humans for 80 years fell to AI algorithms, highlighting the technology's expanding capabilities beyond traditional pattern recognition.

The Commodity Futures Trading Commission cleared Kalshi to launch perpetual futures, giving US investors regulated access to cryptocurrency derivatives that previously traded almost exclusively offshore. Municipal bond funds attracted near-record inflows as investors embraced higher tax-exempt yields ahead of the summer reinvestment season, though short-sellers increased bets against bond ETFs anticipating further rate volatility. Citadel Securities posted record $4.3 billion in trading revenues during the first quarter, earning $1.9 billion in net income as oil prices and Treasury rates fluctuated amid Middle East tensions.

Energy and Commodities

Sugar futures jumped the most in a month on El Niño concerns threatening India's monsoon-dependent cane crop, while Asian rice prices surged 20% in May amid weather risks and energy-driven fertilizer costs. Petra Diamonds Ltd. launched restructuring at its Finsch mine as diamond prices weakened and the South African rand strengthened, reflecting broader commodity market stress from geopolitical uncertainty. One-quarter of large oil tankers escaped the Persian Gulf in a slow trickle despite ongoing military operations, easing some supply chain pressures that had supported energy prices.

Quantinuum Inc., backed by Honeywell International amid growing appetite for quantum computing exposure. Shutterfly Inc. kicked off a $1.9 billion junk bond offering to refinance maturing debt obligations, testing investor appetite for high-yield paper in the retail sector.

Banking and Financial Services

Top UK building societies prepared bids for digital bank Atom after the fintech's owners targeted approximately $600 million in proceeds, though industry executives suggested final offers may fall short of expectations. Citadel Securities lost its court challenge against IEX Group, allowing the new options exchange to launch with intentional speed bumps that favor retail investors over high-frequency traders. BlackRock Inc. trimmed equity exposure across its $220 billion model portfolio business after US stocks reached record highs, reflecting institutional caution despite strong earnings seasons.

Geopolitical Risk and Market Infrastructure
