BlackRock's tokenized US Treasury fund BUIDL has retaken the lead in the race for the largest tokenized Treasury product, with a market capitalization of roughly $2.8 billion. That puts BUIDL at about 18.5% of the $15.1 billion tokenized Treasury market, narrowly ahead of Circle's USYC. The flip comes after USYC briefly surpassed BUIDL in late August, only to lose the top spot again.
The back-and-forth at the top
Neither fund has held the lead for long. USYC grew from about $600 million to nearly $3 billion over the past year, and by late August it had reached roughly $2.9 billion — enough to edge past BUIDL's $2.7 billion at the time. But the lead didn't stick. BUIDL has since reclaimed the top position, and the two are now trading places as institutions move money between them.
This isn't a static ranking. The fact that the top spot keeps changing hands suggests institutions are actively comparing the two products and shifting allocations based on yield, liquidity, or other factors. It's a sign that the tokenized Treasury market is becoming a genuine, contested category rather than a one-fund show.
What these funds actually are
BUIDL is BlackRock's USD Institutional Digital Liquidity Fund, administered by Securitize. It lets institutions hold short-term US government debt on a blockchain, with 24/7 settlement — a big upgrade over traditional bond markets that only settle during business hours.
USYC is a share in Circle's Hashnote-based fund, which Circle acquired in 2025. Circle, best known for the USDC stablecoin, has been pushing into yield-bearing products, and USYC is its answer to BUIDL. Both funds offer similar exposure to Treasuries, but they differ in structure, distribution, and the platforms they integrate with.
Why the competition matters
The fact that two major asset managers are fighting for the same slice of the market is a sign that tokenized assets are maturing. Growth has stayed concentrated in Treasuries, even as the broader real-world asset (RWA) sector expands. That makes sense — Treasuries are the safest, most liquid collateral in finance, and putting them on-chain opens up new use cases like instant collateral movement and 24/7 trading.
For now, the lead is narrow and could flip again. The next few weeks will show whether BUIDL can hold onto its position or if USYC's momentum pushes it back to the top. Either way, the competition is forcing both funds to sharpen their offerings — and that's good for the institutions that use them.
