Three Numbers That Will Define Markets This Week: GDP, PMI, and the Supreme Court Tariff Ruling
Today is one of the most data-heavy days of 2026 for US markets. The Bureau of Economic Analysis releases its advance estimate of Q4 2025 GDP, flash PMI readings give a real-time pulse of manufacturing and services, and the US Supreme Court may finally deliver its landmark ruling on the legality of President Trump's sweeping IEEPA tariffs. Every one of these events has the potential to move markets significantly — and all three land on the same Friday.
