The common mispronunciation of “pro”

✗ Often said: /ˈprɑː/ — the spelling, read straight off the page.

✓ Actually: /ˈproʊ/

Why the two come apart: at least one vowel does not say what its spelling suggests — English vowel letters are not reliable here.

This is why reading English aloud from spelling alone goes wrong so often: the letters of “pro” are not a reliable map of its sounds. The IPA is — each symbol stands for exactly one sound, every time.
