LOS ANGELES, May 27, 2025 /PRNewswire/ -- Thumzup Media Corporation ("Thumzup" or the "Company") (Nasdaq: TZUP), a BTC accumulator and advertising industry disruptor, today announced that the Company will be included on the Russell Microcap® Index at the conclusion of the 2025 Russell U.S. Indexes annual reconstitution, on the US stock market open on June 30, 2025.

The annual Russell U.S. Indexes reconstitution captures the 4,000 largest U.S. stocks as of Tuesday, April 30th, ranking them by total market capitalization.

"We believe that Thumzup's inclusion in the Russell Microcap® Index comes at an inflection point in our growth trajectory – both TZUP and BTC recently hit all-time highs as we continue to execute our Bitcoin accumulation strategy," stated Robert Steele, Chief Executive Officer of Thumzup. "We're honored to join the Russell-indexed family of companies and applaud the recent decision to increase the frequency of rebalancing. The inclusion of Thumzup in a Russell Index is a transformative milestone, which is expected to generate index-fund driven accumulation of Thumzup and improve long-term shareholder value."

Russell indexes are widely used by investment managers and institutional investors for index funds and as benchmarks for active investment strategies. Russell's US indexes serve as the benchmark for approximately $10.6 trillion in assets as of the close of June 2024. Russell indexes are part of FTSE Russell, the global index provider.

Fiona Bassett, CEO of FTSE Russell, An LSEG business, commented, "The Russell indexes have continuously adapted to the evolving dynamic US economy, and it's crucial to fully recalibrate the suite of Russell US Indexes, ensuring the indexes maintain an accurate representation of the market. The transition to a semi-annual reconstitution frequency from 2026 will ensure our indexes continue to represent the market and maintain the purpose of the index as a portfolio benchmark."
