The market cap of tokenized ETFs has crossed the $500 million threshold, and one platform is responsible for the lion’s share. Ondo Finance controls approximately 66.4% of the space, making it the single largest player in a category that barely existed a year ago.

Ondo Global Markets launched in September 2025 with over 100 tokenized assets available on Ethereum. By mid-2026, that number had ballooned to more than 440 tokenized US stocks and ETFs, spread across Ethereum, Solana, and BNB Chain.

Cumulative trading volume on Ondo’s platform has surpassed $9B, with tens of thousands of holders globally, the majority of whom sit outside the US.

The catalyst for the most recent surge appears to be IVVon, Ondo’s tokenized version of a major ETF, which climbed roughly 150% in May 2026 alone. That single product helped push the broader tokenized ETF category from around $430M in May to beyond the $500M mark.

Ondo introduced 24/7 mint and redeem capabilities in June 2026. That feature lets users create or destroy tokenized shares at any time, not just during New York trading hours.

The platform filed an SEC registration statement in February 2026, a move that signals its intent to operate within the existing regulatory framework rather than around it.

BlackRock and Franklin Templeton, two of the largest asset managers on the planet, have engaged with Ondo’s ecosystem.

The platform focuses primarily on non-US investors, and has pursued US compliance through its SEC filing.

Ondo’s 66-74% market share, depending on which analysis you reference, is dominant but not invincible. Regulatory uncertainty remains the biggest overhang. Ondo’s SEC filing is a positive signal, but an SEC filing is not SEC approval. If regulators decide that tokenized securities need to follow the exact same distribution rules as their traditional counterparts, the global accessibility that makes these products appealing could shrink overnight.

When one platform controls two-thirds of a category, any operational issue, smart contract vulnerability, or regulatory action against that single entity could ripple across the entire sector.
