Binance activated two-way 1:1 conversion between tokenized US equities and their underlying shares on October 5, 2026, expanding a product line that had grown to more than $500 million in assets under management by July 28.

Eligible users can swap supported US stocks for BEP-20 tokens called bStocks—and convert them back—without fees or settlement delays, according to a Binance post. bStocks trade on the exchange's spot markets around the clock, including weekends, sidestepping the trading-hour limits of traditional equity venues.

What bStocks are

bStocks are BEP-20 tokens issued on BNB Smart Chain, Binance's flagship smart-contract network. Each token is structured to deliver 1:1 economic exposure to a specific US-listed equity, with the underlying shares held by a regulated custodian.

Binance launched the product on June 11, 2026. Assets under management passed $100 million shortly after debut and crossed $500 million within roughly seven weeks, according to figures disclosed by the exchange.

How the conversion mechanism works

The conversion runs through the Binance wallet and operates 24/7. Once a share becomes a bStock, it can trade continuously on Binance spot markets. Users may also withdraw bStocks to compatible wallets for use in decentralized finance protocols covering lending, borrowing, and on-chain trading.

New bStock listings—ADBEB, FWDIB, and HPEB—began trading on September 30. The October 5 announcement framed the two-way conversion as the principal feature distinguishing bStocks from read-only tokenized equity products.

Where the product sits regulatorily

bStocks operate within a structure approved by the Financial Services Regulatory Authority of Abu Dhabi Global Market, or ADGM FSRA. They rank among the first tokenized securities admitted to the FSRA Official List, the emirate's regulated instrument roll.

Binance addresses collateral transparency through a Proof of Collateral page intended to document the backing behind each bStock.

What risks remain

The model's integrity rests on the custodian honoring its obligations and on Proof of Collateral data staying accurate and current. Once bStocks leave the Binance wallet, users inherit standard crypto-asset risks: smart-contract bugs, wallet security failures, and the operational reliability of any DeFi venue they route tokens through.

The 1:1 conversion path also functions as an arbitrage corridor. If a bStock's market price diverges from its underlying share, the conversion route gives traders a near-instant way back to the real equity, which should keep the two tightly aligned.

What comes next

The product now straddles three structurally separate market segments—regulated equities, crypto spot trading, and ADGM-supervised tokenized securities—each governed by different custody, settlement, and disclosure regimes. The operational test over coming quarters will be whether the conversion holds during extended US equity closures, holiday-thin trading sessions, and episodes of on-chain liquidity stress, and whether additional tokenized equities graduate from the FSRA Official List onto Binance's spot order books.
