The latest one is Vogtle's units 3 and 4, which are Westinghouse AP1000 units, which cost $36.8 billion USD for around 2.2 gigawatts of capacity.
However, recent and upcoming Canadian plants are relevant, because the US and Canada operate a shared electrical grid (excepting Quebec and Texas, and Quebec still has connections to the US and Canada). OPG is currently building GE Vernova Hitachi Nuclear Canada (what a mouthfull) BWRX-300 SMR reactors, with four of them expected to provide 1.2 gigawatts of capacity for $20.9 billion CAD (or $14.8 billion USD), and if we were to predict future costs by assuming future reactors cost the same as reactors 2-4 (as serial production) rather than reactor 1 (the first ever of its type), a similar project, four reactors plus shared infrastructure, would cost $19.2 billion CAD (or $13.6 billion USD). That is roughly two thirds the cost of the latest US reactor, per gigawatt.
Of course, the Darlington project is still fairly early on, and it's possible that costs will be over budget. However OPG does have a good track record in this regard, they recently completed a $12.8 billion nuclear refurbishment project that completed $150 million under budget and four months ahead of schedule.
