They're spending $480k an hour. They're earning $331k an hour. Therefore, they're losing about $150k an hour.
Let's say they continue to lose $150k an hour until August 6 2018. Let's further assume they make $5k on every Model 3. If they can build 30 Model 3s an hour they're golden.
Unfortunately that's 260,000 model 3s per year. Tesla's own goals are 100k per year. Meanwhile, Tesla claims they're making 25% on every Model 3, while UBS thinks they'll lose $6k on each and every one.
100,000 model 3s at $6k loss each is a $600m loss. 100,000 model 3s at 25% profit is an $875m profit. There's a fair amount of slop in there, which is why Tesla stock is so volatile.
You don't need to wonder how much other companies spend per hour. Take their quarterly expenses and divide by 2190. GM, for example, spends $9.7m. Ford spends $2.25m. It's perhaps more useful to look at net income - Despite spending $9.7m per hour, GM profits $2.4m per hour.
If you're General Motors, you're profiting $663 per second. If you're Tesla, you're losing $42 per second. There's a $700 delta there and it's heavily in GM's favor... But Tesla is "worth" $52 billion dollars while GM is worth $62b.
Thus the Tesla hate.
