According to Forbes, driven by gains in SpaceX and Tesla’s share prices, Elon Musk reclaimed his spot as a trillionaire on October 21.

Musk confirmed during SpaceX’s Tuesday evening earnings call that the two companies are exploring a merger. Musk became the world’s first trillionaire on June 12 when SpaceX went public, and has since fallen below and reclaimed the threshold multiple times; he most recently lost the status last week amid a decline in SpaceX’s share price.

According to Bloomberg, prediction market platform Kalshi has struck a new deal with crypto asset custodian BitGo, allowing select clients to borrow funds using their custodied crypto assets as collateral, with the loan proceeds serving as margin for leveraged perpetual futures trading on Kalshi’s exchange. The arrangement is targeted at clients of Kalshi Prime, Kalshi’s U.S.-registered futures commission merchant, and adopts a tri-party collateral management structure. Loans are provided by Kalshi’s affiliated lending firm Kalshi Katalyst, while collateral assets are held at BitGo Bank & Trust. Eligible collateral includes Bitcoin, Ethereum, and stablecoins compliant with the GENIUS Act, with plans to integrate additional custodians in the future. Jeff Bandman, CEO of Kalshi Prime, stated that the setup enables clients to participate in trading without liquidating their crypto holdings, which may attract crypto-native trading firms and large digital asset holders (whales).
