The upside to GS for Tesla to issue stock 3% higher is pretty minuscule, if anything (GS probably priced their take at a 20 day trailing average price, or whatever). The downside is enormous, and compliance and the SEC are crawling over the place. Plus, the issuance is going to take place at whatever price investors think the stock is worth. If investors think there's a big conflict of interest, they'll price that in.
