SPX6900, the memecoin that literally named itself after the S&P 500 index with a higher number, just landed on South Korea’s biggest digital asset exchange. Upbit opened deposits for SPX today at 14:00 KST, with trading available against Korean Won, Bitcoin, and Tether.

What is SPX6900 and why does anyone care

SPX6900 launched in August 2023 on Ethereum with a straightforward, if slightly unhinged, thesis: it wants to “overturn” the S&P 500. The token’s entire brand identity is built around satirizing traditional finance, positioning itself as a meme-powered alternative to the most watched stock index on the planet.

The token started as an ERC-20 on Ethereum but has since expanded to Solana and Base through the Wormhole bridging protocol.

SPX6900 has a total supply of 1 billion tokens, with approximately 930.99 million currently in circulation. Around 69 million tokens, roughly 6.9% of total supply, have been burned. The 6.9% burn figure is almost certainly intentional, given memecoin culture’s affection for that particular number.

At current trading prices between $0.33 and $0.35, SPX6900 carries a market cap in the $315M to $325M range. Twenty-four-hour trading volume sits between $6M and $7M.

The listing trail that led to Upbit

This isn’t SPX6900’s first major exchange listing. Gate.io added the token back in October 2024, and Coinbase followed in September 2025. Each listing expanded the token’s accessibility and liquidity, and the Upbit addition follows that same playbook.
