The Human Genome project took 13 years and cost $3 billion. It was completed in 2003, although some gaps took until 2022 to be filled. We have since sequenced the genomes of many other species. GOLD, the database that tracks this, reports 108,358 eukaryotic genomes. This number will keep going up, driven by massive projects like Darwin Tree of Life, which is sequencing 70,000 eukaryotic species in the UK. All of these are de novo assemblies, meaning that each of them is the genome of a different species.
If you count the number of individuals from the same species, the number of sequenced genomes is much higher. Humans are without doubt the most sequenced eukaryotic species. I couldn’t find a precise number, but my best estimate is 3 million fully sequenced people worldwide, with several million more that had the protein coding parts of the genome (exomes) sequenced.
