Saudi Aramco's annual revenue is over $300B, and their reserves are more than 260 billion barrels. Oil prices have ranged from $15-ish to $140-ish since 1990.

Saudi Aramco's annual revenue is over $300B, and their reserves are more than 260 billion barrels. Oil prices have ranged from $15-ish to $140-ish since 1990. So $2 trillion doesn't seem outlandish at all for Aramco. Early angel investors in Uber have made about 10,000x, plus or minus, so even if you're right there's no potential for shorting Aramco to be the best investment ever (Uber's seed round was at 4 millionish, and the current valuation is 60 billionish).
