What Is the Biggest Gold Bar in the World?

On December 10, 2024, a factory in Dubai poured a single bar of gold that weighs more than an adult lion. It stands 300.12 kilograms, about 661 pounds, and Guinness World Records sent an adjudicator to confirm it was the largest ever made. That’s roughly twenty times the size of the 400-ounce “good delivery” bars that central banks stack in their vaults.

The company behind it, Emirates Minting Factory, didn’t melt down 661 pounds of gold to sell it. They did it to plant a flag. Dubai has called itself the City of Gold for decades, and now it owns the proof. As the company’s chairman, Essa Al Falasi, put it, the bar is “not just a record; it’s a gift to the UAE.” At gold’s mid-2026 price, that gift is worth close to $39 million, and every ounce of it is 999.9 fine.

Dubai’s 300-kilogram bar dethroned Japan’s twenty-year record

Before Dubai, the crown sat in a small museum on the coast of Japan, and honestly it’s the better story of the two.

On June 11, 2005, Mitsubishi Materials Corporation cast a 250-kilogram bar of 99.99% pure gold. Yes, that Mitsubishi, the one on the cars. The company’s materials arm refines the gold, silver, and platinum that go into all sorts of manufactured parts, so pouring the biggest bar on earth was, in a way, just a very large day at the office. The bar is about 8,000 troy ounces, which comes to somewhere north of $32 million today, and it held the Guinness title for nearly two decades until the Emirates broke it by 50 kilograms.

Here’s the strange thing about a bar that big. Gold is so dense that it doesn’t look the part. The Mitsubishi bar measures just 45.5 centimeters long and 22.5 wide, about the size of a briefcase you could tuck under one arm, if you happened to have the strength of a forklift.

Japan’s 250-kilogram bar is the only giant you’re allowed to touch

The Mitsubishi bar lives at the Toi Gold Museum, on Japan’s Izu Peninsula, and the museum does something almost no one else on earth dares to do with $32 million of gold. It lets you reach out and put your hand on it. There’s a worn spot on the bar where thousands of visitors have done exactly that.

The museum earned the right to hold it. It sits on top of the old Toi Gold Mine, and this stretch of coast has been giving up gold since the 1370s. When the shogun Tokugawa Ieyasu ordered the development of the Izu mines in 1601, the town grew so fast that people called it “Toi Senken,” Toi of a thousand houses. By the time the mine finally ran dry and closed in 1965, it had produced an estimated 40 tons of gold and 400 tons of silver, making it the second biggest gold mine in all of Japan, behind only the legendary Sado.

Today you can walk the real Edo-period tunnels, pan for actual flecks of gold in warm spring water, rinse your coins in a spring that’s supposed to multiply your luck with money, and buy an ice cream cone dusted with edible gold leaf. It is a museum about gold that could not resist covering itself in the stuff.

Nations and companies keep competing to build the biggest gold objects

Once a country or a company gets the itch to build the biggest gold something, it turns out they rarely stop at bars.

Bangkok is home to the largest solid gold statue on earth, a three-meter Buddha made of about 5.5 tons of gold that sat hidden under plaster for almost 200 years before a crew accidentally chipped it in 1955 and found the treasure underneath. A Chinese jeweler forged an 82-kilogram gold ring in 2016. A Japanese resort built a gold bathtub that reportedly took eight months and four million hammer strikes. And in 2010, a hotel in Abu Dhabi installed the world’s first ATM that spits out gold bars instead of cash.

America had its own era of showing off. In October 1882, a hydraulic mining company in Nevada County, California, poured a promotional bar of 6,127.78 troy ounces, and a group of Montana mines later combined a season’s haul into a single 6,995-ounce slab. These weren’t for spending. They were proof, cast in metal, that the mine paid, meant to be photographed and paraded in front of investors.

Bigger bars carry smaller premiums, which is why size matters when you buy

You are never going to own the Dubai bar, and neither are we. But those giants make a point that matters for anyone buying real gold: the bigger the bar, the smaller the premium over the metal’s actual value. That’s why banks hold 400-ounce bars and why a serious buyer will often size up rather than collect a drawer full of one-ounce pieces.

For most people, a one-kilogram bar is about as large as it gets before storage and resale turn into a headache, and there’s nothing wrong with a stack of one-ounce coins either. If any of this has you curious where you’d start, you can check live spot prices, look through our gold bars and coins, or call one of our commission-free brokers and just ask. We can’t pour you a 661-pound bar, but we’ve been putting gold in Americans’ hands since 1973, one manageable piece at a time.
