📊 Who’s backing crypto in 2026?

Even in a selective market, major players are still placing bets on the next wave of crypto infrastructure and products

[Castrum Istanbul @castrumistanbul]

We’re doubling down on @SwarmBase.
After leading its previous round, Castrum has made a follow-on investment in SwarmBase, reinforcing our long-term conviction in the team.

SwarmBase is building the coordination layer for autonomous AI agents, and the team’s execution made this an easy decision.

We believe SwarmBase is well-positioned to lead the next wave of agentic AI.

[SwarmBase @SwarmBase]

We are excited to announce that SwarmBase has raised $7M in total funding after closing a $4M follow-on investment from @castrumistanbul, building on our initial round backed by @castrumistanbul, @M2MCapital, @notchvc and @BeckerVentures.

SwarmBase is the agentic AI infrastructure platform where autonomous agents collaborate, build, and evolve. Deploy coordinated AI swarms that research, reason, build, and execute any task without human intervention.

From deep research and full stack development to enterprise decision workflows, SwarmBase is the coordination layer for the next generation of AI.

Agentic Intelligence at Scale.

.@Circle is in Istanbul. @jerallaire is in Istanbul. Stablecoin payments aren’t a trend anymore they’re becoming infrastructure. The market is clearly shifting toward institutional adoption, and that’s telling us where the next cycle is headed.

[Castrum Istanbul @castrumistanbul]

Interesting perspective we get what you're trying to say.

That said, I'm not sure Uber and Airbnb are the best comparisons for Binance. The regulatory and operational dynamics of crypto infrastructure are fundamentally different from those of the sharing economy. Still, I agree that regulatory challenges don't necessarily define the long-term outcome.

[Yi He @heyibinance]

Thinking about the EU and crypto, I see some parallels to the largest players in emerging tech, such as Airbnb and Uber（Try asking the AI: In which countries have Uber and Airbnb been banned? ）Many global tech giants’ regulatory setbacks but came back stronger for it.
As for Binance and Europe, we take this market seriously. It's a small part of our business, but an important one, and we're committed to the EU and our customers there.
Building trust with regulators takes time—through engagement and better communication. We're committed to doing that work.
It is my expectation that Binance, and other crypto providers, will become the strongest gatekeepers of the financial system, far more than TradFi given the underlying technology and market forces driving adoption. We've made real strides in recent years and we're not slowing down.
We intend to get this right, and we are working hand in hand with EU and national regulators.

FUNDS ARE SAFU. https://t.co/NlVhsUO5Da

任何一个新兴行业在发展过程中，都会遇到不同程度的监管挑战和竞争挑战，就像Airbnb和Uber（试试问AI他们曾经被哪些国家禁止过？）但这不影响他们成为移动互联网时代最伟大的互联网公司。
Binance始终将遇到的问题视为提升我们团队能力和标准的机会。在过去几年，我们建立了行业用户资产透明度的标准，我们在合规上建立了行业的最高标准；对于欧盟地区的监管部门对于Binance建立有效的��通与信任也许还需要时间，但我们不会放弃。并将继续遵循全球加密行业合规的黄金标准。
合规是近期大家非常关注的话题，我认为这是行业的进步，说明行业从草莽期逐渐转型开始自我约束与自律。但这次我得到的经验与教训是：拿到牌照的公司并不一定合规也不一定自律，而币安遵循黄金标准的合规也不一定能会拿到牌照，但我们的目标是星辰大海，不是和同行在泥坑打滚，我们会以行业的最高标准要求自己。

Perp DEXs are quietly winning the most important battle in DeFi.
On-chain perps already do billions in daily volume and they're capturing it without custody risk, without KYC walls, and without a CEX deciding what you can trade.

The infrastructure finally caught up: low-latency orderbooks, deep liquidity layers, cross-margin, sub-second execution. The "CEX UX, DEX trust" gap is closing fast.

The next cycle won't be about whether perp DEXs can compete with centralized venues. It'll be about how much share they take.

Self-custody + leverage + permissionless markets is a hard combination to bet against.
