Binance bStocks’ SPYb token accumulates $6M in DeFi liquidity

Binance’s tokenized stock platform bStocks has produced a quiet breakout hit. SPYb, a BEP-20 token that gives holders 1:1 economic exposure to the SPDR S&P 500 ETF, has pulled in roughly $6.3 million in deposits across DeFi platforms. The token, which lives on BNB Smart Chain and is fully backed by custodied SPY shares, launched alongside the broader bStocks platform in June 2026. In the two months since, SPYb has become one of the most actively traded tokens in the bStocks lineup, with DEX liquidity reaching approximately $6.5 million and an estimated market cap somewhere between $17 million and $22 million.

From zero to $624 million in two months

The platform crossed $100 million in assets under management just 15 days after launch. By early August 2026, that figure had ballooned to roughly $624 million. bStocks offers a range of tokenized US equities and ETFs, but SPYb has emerged as the flagship. Holders can withdraw their tokens to self-custody wallets and plug them into automated market makers, lending protocols, and other DeFi applications. The shares backing the tokens are held in custody by BTech Holdings Limited, which issues the bStocks instruments.

Why DeFi liquidity matters here

Traditional stock markets operate on a roughly 6.5-hour trading window, five days a week. SPYb trades around the clock on the Binance spot exchange and across DEXes. Users can deposit SPYb into lending protocols to earn yield or use it as collateral. As of mid-July 2026, tokenized stock lending had reached a total value locked of $23 million across the sector. Daily trading volumes for SPYb have been running in the millions, with on-chain metrics showing increasing DEX volume and growing deposits.

The elephant in the room: scale

The actual SPY ETF manages over $500 billion in assets. bStocks’ entire platform, at $624 million, amounts to roughly 0.1% of that. And $6.3 million in DeFi liquidity, while impressive for the tokenized stock category, would barely register as a rounding error in traditional finance. BTech Holdings Limited issues the bStocks tokens, and the platform emphasizes that each token is fully backed by the underlying security held in custody.
