Ondo's USDY just passed BlackRock's BUIDL

Ondo's USDY held $2,383,581,044 on October 29, according to RWA.xyz, making it the largest individual tokenized U.S. Treasury product on the leaderboard. BlackRock's BUIDL, the fund that opened this category in March 2024, sits at $2,186,463,900. The gap is about $197 million, and it has widened for three straight weeks.

The direction matters more than the snapshot. Over the past 30 days USDY grew 4.7% while BUIDL shrank 2.73%, both per RWA.xyz. USDY added 5.57% more holders over the same stretch, reaching 17,945. BUIDL counts 102, but holder counts compare badly here: BUIDL is a U.S. qualified-purchaser fund with a $5 million minimum, and USDY is a Regulation S note sold to non-U.S. individuals and institutions. Different buyers, different rails. The growth rates are what the leaderboard is actually measuring.

One caveat before the confetti. Circle's USYC, at roughly $2.37 billion as of October 29, trails USDY by less than $10 million. That is a rounding error on a money fund. USDY did not just overtake BUIDL; it sits one redemption day ahead of USYC for the overall top spot. Treat the number-one ranking as a photograph, not a trophy.

For scale, the whole distributed tokenized Treasury category held $14.59 billion as of October 28 across about 119 funds, with a 7-day market APY of 3.74%, per RWA.xyz.

The league table under the flip

Product rankings hide how concentrated this market is at the issuer level. RWA.xyz's platform table, as of October 28 and summarized by Admiral Markets, has Ondo first at about $3.1 billion across 11 products, roughly 21% of the category. Franklin Templeton follows at $2.7 billion across 4 products, then Circle with $2.4 billion in a single fund, Securitize with $2.3 billion across 4, Kinexys Digital Assets at $892.4 million and WisdomTree at $768.4 million.

Ondo's platform lead is broader than USDY, but USDY is the engine: the token runs native supply on Ethereum, Stellar, SEI, Solana, BNB Chain and Arbitrum, according to RWA.xyz. No other Treasury product is deployed across that many chains by default.

The fine print

Three things the headline skips, mostly drawn from Yahoo Finance's piece on the flip and RWA.xyz's fund facts.

First, Ondo and BlackRock are not purely rivals. In March 2024 Ondo placed the reserves of its institutional product OUSG into BUIDL, making Ondo a BUIDL client. USDY's collateral portfolio includes a tokenized version of the iShares 0-1 Year Treasury Bond ETF, which BlackRock manages. Some share of every dollar flowing into the product that beat BlackRock pays fees to BlackRock.

Second, the products do not compete for the same investor. BUIDL serves U.S. qualified purchasers; USDY cannot be sold to U.S. persons. The flip says crypto-native distribution is outrunning institutional distribution, not that a U.S. institution stopped buying BUIDL.

Third, the market's reaction was odd. The ONDO governance token fell about 9% in the week ending October 17, the same week the flip was confirmed, and ONDO holders have no claim on USDY's reserves or Ondo's revenue. Token price and product traction can decouple, and this is a clean example.

The read

Distribution explains most of this flip. When Treasury yield is 3.68% to 3.74% everywhere, the product that shows up where crypto capital already lives wins the flows. USDY settles on six chains, pays monthly, and gets accepted as collateral in crypto lending and trading venues. BUIDL grows through negotiated institutional relationships, which is a slower flywheel and, this quarter, one that went briefly backwards at -2.73% over 30 days.

The asterisk I keep coming back to is USYC. Circle runs the same playbook with a bigger brand in payments, and it is $10 million behind. The race that will still matter in six months is USDY versus USYC, with BUIDL as the institutional benchmark rather than the contested position.

Watch two things: whether BUIDL's 30-day decline develops into a second straight month of outflows, and whether USDY can hold the top spot once USYC's flows turn. The category itself keeps compounding either way.
