Not nothing, for sure, but low enough that you can buy it back in a couple of months.
By purchasing OAI shares now, Softbank will probably be able to sell them to Nvidia at inflated prices later.
Also, I highly doubt they sold those 5bn of shares in any exchange. Most likely they did it over several weeks on a dark pool. Because again 5bn is massive and it would cause a crash in any open exchange.
But hey, maybe the market crashes tomorrow and this is seen as the best piece of timing ever seen, maybe it doubles in the next year.
In any case, you never lose by taking profit.
Until it wasn’t. Then it was again.
Either way, cash flow != stock price, not that SoftBank is in a ‘business’ that likely needs a lot of cash.
Maybe they just needed a new yacht?
Or need to bail out one of their investments?
