Kraig Biocraft Laboratories Inc (KBLB)

Bolt Threads Inc. did capture VC interest and is targeting 2016 as their commercialization date, so they obviously have something, but I have not seen anything that shows what it is that they do have. Usually by now, you could find some sort of patent in progress, but I have not seen anything, so it is hard to tell what they do have.

One thing I did find is that they have a trademark in progress called BOLTSPUN™ and have registered the domain BOLTSPUN.COM, so that is what they will likely be calling their silk.

The only thing that I found that they cited was that their silk is stronger than steel. If this is in reference to common structural steel, it has a yield strength of 250 Mpa. This means that it likely rivals the properties of Monster Silk® which was cited in the NIAS article of having a Max Stress of around 300 Mpa. That would still not in the Gpa range that KBLB’s Dragon Silk™ and Spiber Inc.’s QMONOS™ fibers seem to be in which is likely why they are aiming for the mundane silk market. I would not be surprised if they come out with a stronger fiber in the future, though. They do seem to have a lot of talent working with them.

If they have succeeded in lowering the cost of creating these fibers to less than the cost to harvest them from silkworms, then they just might eclipse KBLB, at least until Dragon Silk™ comes out, but I would wait until they cite actual figures on cost and properties before I state that they will be the leader of the next generation of textiles.
