Just last week, the FT reported that Tether’s considering a US-only stablecoin. Why? Because their current $144 billion-dollar stablecoin USDT may not comply with potential new US regulation (which is still making its way through the relevant checkpoints down in DC).

Wintermute, in its last weekly market update, noted that some of USDT’s market share had been “eroding,” thanks to both the as-of-yet nonexistent US regulation and, of course, MiCA.

Here’s why it matters: No doubt, Tether is still the biggest and — as we’ve seen Circle’s S-1 — most profitable player in the space right now. But, as I’ve been writing the past couple of months, regulation and adoption could lead to further shakeups as we get new entrants into the space and as others eat up more market share.

“The stablecoin market cap soared 15% in 2025 to a record $233 billion, with USDC fueling much of the growth by adding $16 billion compared to USDT’s $7 billion increase,” Wintermute wrote.

Then, let’s take a look at specific ecosystems.

You have Tron, which saw a $6 billion bump — from $61 billion to $67 billion — pretty much only driven by USDT.

Solana’s stablecoin market cap sits at $12 billion now, up from $5.3 billion.

And over on Ethereum, USDC’s market share has jumped to 30% while USDT slipped slightly to 52% (a 4% decline), though it held on to its $64 billion valuation.

I am in no way, shape or form rooting for any of the OG stablecoin issuers to lose their footing or profitability; that’s not why this type of data interests me. Rather, I think competition in the space is good, and it’s a win-win for consumers: force the heavyweights to keep innovating without monopolizing and make space for the new wave of entrants.

It adds a little spice to the sector. What’s wrong with a little spice?

Kinetiq Protocol: From LST Infrastructure to HIP-3 Deployer

Kinetiq has established itself as Hyperliquid's dominant liquid staking protocol, holding 82.5% of LST market share with $610M in TVL. The protocol is now expanding beyond its kHYPE staking core into higher take-rate verticals: iHYPE for institutional custody rails, Launch for HIP-3 capital formation, and Markets for builder-deployed perpetuals. We view Markets, launching Jan. 12, as the highest-potential product line given its mechanically scalable, activity-linked unit economics. Near-term revenue remains anchored by kHYPE's KIP-2 fee schedule (~$1.6M annualized), while Markets provides embedded optionality if HIP-3 economics normalize post-Growth Mode. KNTQ's setup is relatively clean: zero insider unlocks until November 2026, 6.2% buyback yield from staking revenue, and cleared airdrop overhang. Risks center on unproven Markets execution, declining kHYPE TVL despite ongoing incentives, and competition from Hyperliquid's native initiatives.
