Largest IPO by Market Cap in 2026: SpaceX Holds Top Spot on Polymarket Despite Hawkish Fed-Driven Risk-Off Mood

The U.S. dollar hit a more-than-one-year high as markets priced in a more hawkish Federal Reserve after its first policy meeting under new Chair Kevin Warsh. That shift in macro expectations did little to dislodge the Polymarket market on the “Largest IPO by market cap in 2026?” contract, where SpaceX remained the dominant pick despite a small dip in its implied odds.

Key Takeaways

• SpaceX leads Polymarket’s “Largest IPO by market cap in 2026?” market at 85.5% implied odds.
• The repricing came alongside a broader risk backdrop tied to hawkish Fed expectations that lifted the dollar and hit equities, while the SpaceX outcome eased by 1.0 point.
• The contract is set to resolve on 2026-12-31, with odds little changed over 24 hours and 7 days in the available summary.

The U.S. dollar climbed to its highest level in more than a year as investors shifted toward a more hawkish outlook for the Federal Reserve following last week’s policy meeting, the first chaired by Kevin Warsh. Markets increased the implied probability of at least a 25-basis-point rate hike at the July meeting to 36.3% from 8.5% a week earlier, while pricing a 69.1% chance of a hike in September versus 29.1% a week earlier. The dollar index rose 0.38% to 101.39 after touching 101.42, its strongest since May 2025, as the euro fell to about $1.138 after hitting its lowest since June 2025. U.S. equities weakened, with the S&P 500 and Nasdaq falling on technology-led selling, while the dollar held near 161.55 yen with a nearby level flagged as a potential break toward the weakest yen since 1986. Investors were also focused on upcoming U.S. inflation data, including the May Personal Consumption Expenditures Price Index due Thursday.
