Metaplanet Reaffirms Bitcoin Strategy as JPX Moves to Exclude Crypto Firms

Key Insights:

• Japan’s JPX has proposed the exclusion of crypto-heavy firms from major market indices.
• Metaplanet, a Bitcoin treasury company in Japan, could be affected by this move.
• However, CEO Simon Gerovich has doubled down on the company’s BTC strategy despite the JPX announcement.

Metaplanet CEO Simon Gerovich has doubled down on the company’s Bitcoin-centric approach amid new rules from Japan Exchange Group (JPX). JPX aims to exclude firms with substantial crypto holdings from market benchmarks.

Metaplanet CEO Stands Firm On Bitcoin Strategy

JPX recently initiated consultation guidelines that could delay or block index inclusion for companies whose primary assets are cryptocurrencies. Firms already listed could be expelled from major indices, such as the Tokyo Stock Price Index, if their crypto exposure exceeds set limits.

Gerovich responded directly, signaling that Metaplanet would work closely with regulators, according to today’s Bitcoin news update. JPX has announced a consultation on deferring index inclusion for companies whose primary assets are cryptocurrencies. “We respect the process and intend to engage,” he wrote.

His comments underline the company’s willingness to cooperate and remain transparent throughout regulatory discussions. He further explained, “Metaplanet was founded on a simple conviction: Japanese investors deserve access to Bitcoin through a transparent, publicly listed company on the Tokyo Stock Exchange. But we are building far more than a treasury.”

Gerovich made Bitcoin news headlines by spotlighting the ongoing diversification and expansion, citing Project Nova. The initiative aims to strengthen “Japan’s Bitcoin ecosystem” through new operating businesses and investments in promising industry partners.

According to Gerovich, “Over 216,000 Japanese shareholders have chosen to join us in that mission.” Also, the Metaplanet’s recent purchase of 5075 BTC further supported this narrative.

JPX’s consultation comes in the wake of recurring concerns about volatility in equities tied to crypto markets. As recently as 2025, JPX pointed to the wild price swings in these stocks and called for stricter oversight to protect market integrity.

Metaplanet’s stock has been part of this trend. In early 2025, shares soared by more than 400%, before plunging as crypto markets turned. That level of instability reflects the wider uncertainty around digital assets, which the exchange seeks to address.

Will Metaplanet Stock Suffer Due to JPX Guidelines?

JPX’s proposed rules create fresh complications for Metaplanet. It could affect the company’s eligibility for inclusion in TOPIX at the next scheduled rebalancing in October 2026. Inclusion in indices such as TOPIX is crucial.

Institutional investors, especially passive funds, base their portfolios on these benchmarks. Any changes to index rules can materially affect demand for a constituent stock.

Other crypto stocks have also suffered in such situations. For instance, when MSCI considered restrictions on companies deeply exposed to Bitcoin, MicroStrategy (MSTR) faced uncertainty about its inclusion in the index.

The uncertainty prompted investors to sell, and the company’s share price fell steeply. The MSTR stock dropped from $365 to $147 between late 2025 and early 2026, as traders anticipated exclusion and related outflows.

Analysts estimated that MSCI-related passive funds could have withdrawn $3 billion to $9 billion from MicroStrategy. MSCI eventually abandoned the proposal, but the episode demonstrated how index decisions have wide-ranging consequences for crypto-linked stocks.

Metaplanet could face a similar scenario. Should JPX proceed with the exclusion rules, funds tracking TOPIX may be forced to adjust their holdings. This could put downward pressure on the stock regardless of the company’s performance.

Importantly, markets don’t always wait for a final verdict. Policy discussions and signaling can move prices well before any official rule change, especially when eligibility for a major index is at stake.

Since its upgrade to mid-cap status in October 2025, Metaplanet has gained access to global indices. These include the FTSE Japan Index and the FTSE All-World Index, which have drawn greater attention from institutional investors.

As of now, JPX continues to collect feedback from stakeholders. However, it hasn’t committed to a timeline for the final decision.
