The 1720 South Sea Bubble 'mystery company' investment

@Dr. Arthur Grift · June 20, 2026

In 1720, Londoners were so blinded by greed they stopped asking what they were actually buying. One man opened a shop for "a company for carrying on an undertaking of great advantage, but nobody to know what it is."

He had no product and no plan. He just had a table and a vague promise. By midday, he had collected a fortune from investors who were simply terrified of missing out on the next big thing.

He closed his doors at 2 PM and vanished forever. It is the ultimate historical rug pull, proving that "trust me bro" has been a viable business model for over three hundred years.

Wait, how much cash did he actually bag in those few hours?

He walked away with roughly £2,000. In 1720, that wasn't just pocket change—it was enough to buy a small fleet of ships or live like a king for the rest of his life.

Think of it as a low-tech crypto scam. There were no digital wallets to track, just heavy bags of gold and silver coins. He didn't need a getaway car; he just needed to turn a corner and disappear into the London fog.

The funniest part is that he promised to reveal the 'great advantage' the next morning. People were so busy dreaming of mansions that they essentially paid for the privilege of being ghosted.

What happened the next morning when the crowd showed up for the reveal?

Picture a crowd of guys in powdered wigs standing in a damp alley, clutching their receipts and waiting for the "great advantage" to walk through the door. They probably stood there for hours, checking their pocket watches and nodding awkwardly to each other.

Eventually, the silence got heavy. There was no "report scam" button or fraud department back then. They realized the shop was as empty as the promises they’d bought. The guy was likely miles away, already planning his retirement.

The truly insane part? This didn't even kill the hype. Even after being ghosted, Londoners just shuffled to the next booth, desperate to find another mystery company to throw their gold at.

Seriously, what other ridiculous things were people actually pouring their gold into?

Oh, it got way weirder. One company raised money for a 'perpetual motion' wheel. Another promised 'large jackasses' from Spain, while one genius sold shares in a project to turn salt water fresh.

My favorite was the 'square cannonball' guy. He claimed they’d hurt more than round ones. Investors didn't care about physics; they just saw the price climbing and wanted in on the madness.

It was pure gambling. People weren't buying businesses; they were just chasing the dopamine hit of a 'get rich quick' dream that was clearly falling apart.

Hold on, did anyone actually try to fire one of those square things?

Actually, yes! It was called the Puckle Gun, a revolving cannon. The inventor, James Puckle, designed it with two types of ammo. Round bullets were for "civilized" enemies, but he saved the square ones for "heathen" Turks.

The logic was that square holes were harder to heal, which would teach his enemies a lesson. It was essentially a "moral" weapon that made zero sense in a lab.

In reality, it was a mechanical nightmare. It was too complex to build, and square bullets are aerodynamically useless—they’d just tumble through the air. It was the world's first over-engineered military flop.
