SBI Holdings just wrote Gauntlet a $125 million check, alone, the largest single-investor bet yet on the idea that DeFi needs professional risk managers as much as it needs protocols.
Tarun Chitra started Gauntlet in 2018 building simulations to stress test DeFi protocols before they broke in public. On July 9, the company announced it had closed a $125 million Series C, funded entirely by SBI Holdings through its U.S. subsidiary, SBI Holdings USA. No other investor joined the round. That detail matters: SBI didn't need a syndicate to get comfortable writing the check.
The number dwarfs Gauntlet's last raise. Back in 2022, Ribbit Capital led a $23.8 million Series B that valued the company at $1 billion, according to Bloomberg. Gauntlet hasn't disclosed a new valuation this time, but a round more than five times the size of the last one tells you the business looks different than it did four years ago.
It is different. Gauntlet isn't just modeling risk anymore. It's curating it. The company now runs vaults, non-custodial structures where institutions deposit digital assets and Gauntlet deploys the capital into yield strategies it has already vetted. Picture a mutual fund, except the fund manager is a risk-modeling firm and the shares settle on a blockchain instead of through a brokerage. Gauntlet says it curates more than $1.5 billion in supplied assets across those vaults and integrates with over 150 fintechs and institutions.
Chitra put the ambition in plain terms in the announcement. "Vaults have proven themselves to be the next major revolution in financial markets," he said, comparing the shift to how ETFs pulled ordinary investors into equities. He expects tokenization and vaults to grow the DeFi market faster than stablecoin issuance itself over the next few years.
That's a big claim from a founder with a stake in it being true. You don't have to take his word for where the money is actually headed, though. SBI has been building toward this exact thesis for a while.
SBI, worth more than $10 billion on the Tokyo Stock Exchange, was spun out of SoftBank in 1999 and now runs its own book independent of Masayoshi Son's ambitions. It already holds stakes in the crypto lender Morpho, the payments network Ripple, and the stablecoin issuer Circle. It was also the sole investor behind institutional trading platform EDX Markets' $76 million Series C. Gauntlet is another leg on a table SBI has spent years assembling: lending, payments, stablecoin issuance, and now the risk infrastructure sitting underneath all of it.
The money has somewhere specific to go: Gauntlet plans to expand stablecoin coverage beyond the dollar and the euro, adding the Mexican peso, the Japanese yen, and other fiat-backed tokens. A yen-denominated stablecoin is expected to launch in the second half of 2026, right in SBI's home market.
Frankly, that's the detail worth watching.
A firm that made its name grading the safety of lending parameters on protocols like Aave and Compound is now underwriting yield products denominated in currencies most DeFi platforms have never touched. If Gauntlet gets the yen stablecoin right, it has a working template for the peso, and eventually whatever else SBI's network reaches across Asia and Latin America.
None of this means DeFi risk management is a solved problem. Vaults still fail when the underlying strategy breaks, and no amount of curation removes that risk entirely. What's changed is who's willing to put institutional money behind the bet that someone can price that risk competently at scale. SBI just did, and at a size no single backer has matched in this corner of crypto.
