In reference to this reddit, I'd like to mention, that the Large Bitcoin Collider LBC has recently passed the 1000 tn mark of searched private keys.

As both uncompressed and compressed addresses are searched, a total of over 2000 trillion addresses was searched and checked against the ~11 million addresses with funds on them.

While these numbers may seem large, compared with the search space of BTC addresses, it's a negligible amount of search space – but it demonstrates what a small group of enthusiasts is able to achieve.

The trophies page lists what the pool has found so far: the first 50 addresses of the puzzle transaction plus two addresses with funds on them.
