I would not bet on it.

Sometimes there are gaps and holes in large-size computations, and when someone gets around to fill up the gaps - a new prime is found. This happened in one of the PrimeGrid projects before, iirc. This also happened in Gaussian-Mersenne search while closing a gap that was left undone.
