Actually, sorry to inform you
Actually, sorry to inform you that California has been in the running for weeks now. Texas and other states might have been used as a ploy to extract better concessions from California, however what's a fact is that state and local officials have been in contact with Tesla for several weeks now. California not only has the ability now to extract lithium from brine from geothermal sources, but such sources are in regions with ample and cheap land, global centers for renewable energy and with access to rail. You can be sure there will be generous incentives as well. Musk is no dolt, he would not invest in a state which is hostile to disruptor such as Tesla and does not allow it to sell cars due to corrupt state mafias which are opposed to change.
