Market maker Citadel Securities has disclosed a 5.5% stake in Silvergate Capital (SI) worth about $25 million.

According to a Form 13G filed with the Securities and Exchange Commission (SEC), Citadel Securities is now the owner of roughly 1.73 million shares or a 5.5% stake in Silvergate, valued at $25 million based on Monday's closing price of $14.71.

A person familiar with Citadel Securities told CoinDesk that the filing is a result of the firm's options market making activities rather than a directional investment or stake in Silvergate. Citadel Securities makes markets in more than a million individual options at any time. For 13G filings, options positions are calculated based on long call positions, regardless of any offsetting short calls or puts, explained the person.

Meanwhile, trading firm Susquehanna also reported in a filing that it bought about 2.37 million shares, or a 7.5% stake, in Silvergate. The investment would be valued at about $35 million, based on Monday's closing price.

Alongside a modest rally in the price of bitcoin, Silvergate shares are higher by just over 5% on Tuesday at $15.53. Shares are down about 87% over the past year.

The moves come after BlackRock said it boosted stake in Silvergate last month. A filing showed that the asset management giant had a 7.2% stake in Silvergate Capital as of Dec. 31, as oppose to a 6.3% stake, reported a year earlier.

KuCoin Hits Record Market Share as 2025 Volumes Outpace Crypto Market

16:9 Image

KuCoin captured a record share of centralised exchange volume in 2025, with more than $1.25tn traded as its volumes grew faster than the wider crypto market.

What to know:

  • KuCoin recorded over $1.25 trillion in total trading volume in 2025, equivalent to an average of roughly $114 billion per month, marking its strongest year on record.
  • This performance translated into an all-time high share of centralised exchange volume, as KuCoin’s activity expanded faster than aggregate CEX volumes, which slowed during periods of lower market volatility.
  • Spot and derivatives volumes were evenly split, each exceeding $500 billion for the year, signalling broad-based usage rather than reliance on a single product line.
  • Altcoins accounted for the majority of trading activity, reinforcing KuCoin’s role as a primary liquidity venue beyond BTC and ETH at a time when majors saw more muted turnover.
  • Even as overall crypto volumes softened mid-year, KuCoin maintained elevated baseline activity, indicating structurally higher user engagement rather than short-lived volume spikes.

Coinbase’s Base faces builder backlash over creator coin push

Builders on Base are pushing back against the network’s close alignment with Zora, arguing the creator-coin narrative sidelines established projects.

What to know:

  • Base has seen a surge in creator-coin issuance via Zora, with daily token mints surpassing Solana in August, boosting onchain activity and attention.
  • Some Base-native projects say marketing and social support has become narrowly focused on Zora-linked initiatives, leaving other established communities without recognition.
  • While Base continues to process more than 10 million transactions per day, critics warn that deteriorating builder sentiment could push projects toward rival chains like Solana or Sui.
