Why do you think you're right?

Recent years average 1090 per year, so baseline is 5450 (h/t @thsavage). But 2025 funding cuts are unprecedented. Students already enrolled will mostly complete, but new enrollments are heavily affected.

Why might you be wrong?

Pipeline protection might be stronger than expected. Funding could stabilize or improve post-2028.

Why do you think you're right?

November's strong performance ($52.2M globally) confirms Q4 seasonal patterns exist, but 2025 still tracks significantly below 2024 overall. My forecast assumes 2026 sees modest recovery as conditions stabilize, but the two-year combined total barely exceeds what 2024 achieved alone.

Files
Why might you be wrong?

November's strength could signal the start of a faster recovery than I'm projecting.
