85,000 new H1B's. But there are multiples of that already in the US who already hold visas. So, the actual number is in the hundreds of thousands, enough to make a serious impact on supply of labor in the tech sector.
Needless to say, that doesn't make any sense.
You're right that I shouldn't have said 80%, but this still implies almost half of all job postings are ghost jobs from companies trying to hire H1-B visa workers.
It's still an insane claim.
