Recent Performance and Market Context

Price Evolution

Sei’s price action has captured significant market attention in 2024–2025, reflecting a robust base amid the broader digital asset resurgence. Following a sustained period of volatility in late 2023, Sei demonstrated relative outperformance, consistently trading within its higher quartile compared to Layer 1 peers. The current price, reflecting an approximately 40% appreciation year-on-year, underscores bullish accumulation phases supported by clear incremental demand from both retail and institutional market participants.

Recent Positive Events

• Protocol Updates: Recent upgrades have drastically improved Sei’s transaction throughput, slashing confirmation times and bridging lags, particularly on cross-chain DeFi use cases.
• Major Exchange Listings: Listings on top-tier exchanges (e.g., Binance, Coinbase) in the past six months have generated notable increases in trading volume and network exposure.
• Ecosystem Funding: New ecosystem funds (> $60m) were announced in Q2 2025 to incentivise DeFi and NFT developers—expanding the talent pool and application diversity.
• Strategic Partnerships: Recent integrations with Ethereum and Solana DeFi protocols have positioned Sei as a modular interoperability layer, a catalyst for protocol TVL and user base acceleration.

Macro/Sector Context: Crypto Favourable Winds

• Institutional Flow: Large asset managers and crypto-native hedge funds have entered Sei positions, as indicated by on-chain wallet concentration and OTC flows.
• Regulatory Tailwinds: Increased jurisdictional clarity in Europe and APAC facilitated new investment flows, specifically targeting high-throughput, EVM-compatible Layer 1 platforms.
• Modular Trend: The sector’s pivot toward modular blockchain architectures (app-chains, data availability layers) means protocols like Sei—offering scalable, composable infrastructure—are at the forefront of structural upside.

Technical Analysis

Relevant Crypto Indicators

• RSI (14-day): Currently oscillating in the 58–64 band, indicating moderate momentum with upside room before overbought conditions emerge.
• MACD: Recently flipped to a bullish cross above signal line, supporting further price extension over the coming weeks.
• Moving Averages: Sei trades comfortably above its 21-day, 50-day, and 100-day EMAs. The 21/50 EMA compression signals a supportive trend structure, with clear upward slope confirmed at higher timeframes (3M, 6M).

Robust Supports and Reversal Signals

• Immediate Support: The $0.54–$0.56 zone has repeatedly acted as a floor, absorbing major sell-side pressure.
• Upside Pivot: Breakouts above $0.62 have served as triggers for accelerated buying, with order book depth confirming strong market-makers’ activity.
• Short/Mid-term Momentum: Volume surges and positive funding rates reinforce the short-term bias, while medium-term structure now points to higher highs if $0.68–$0.73 levels are breached with conviction.

Fundamental Analysis

Growing Adoption and Ecosystem Strength

• User Growth: Active wallet numbers have surged >75% YTD, outpacing Layer 1 averages; new dApps onboarding per quarter has doubled compared to 2023.
• Developer Activity: Github commits and grants data place Sei among the top 5 fastest-growing Layer 1 ecosystems since mid-2024.
• Strategic Partnerships: Collaboration with Web3 data providers, as well as enterprise DeFi initiatives, reinforce Sei's multi-segment appeal.

Attractive Relative Valuation

• Market Cap: As of June 2025, Sei maintains a market capitalisation of ~$1.3B, trailing leading L1s by a wide margin—implying room for multiple expansion.
• FDV and TVL: The Fully Diluted Valuation/TVL ratio remains below sector medians, suggesting undervaluation given the protocol’s escalating DeFi activity and asset inflows.
• Liquidity: Consistently ranks top 10 in CEX and DEX volumes for non-EVM L1s, with order book depth and slippage metrics indicating institutional-grade liquidity.

Structural Strengths

• Technology Differentiation: Sei’s parallelised execution and transaction finality (sub-second) set it apart within modular blockchains, solving scaling for orderbook-based DeFi.
• Community and Governance: Strong global community presence—AMA engagement, developer hackathons, and DAO governance votes routinely exceed sector benchmarks.
• Sustained Ecosystem Investment: Ongoing foundation support and third-party VC funding remain robust, underpinning the protocol’s next growth phase.

Volume, Liquidity, and Positioning

• High Exchange Volumes: 24h volume averages $170m+ across leading venues, a testament to rising investor confidence and market traction.
• Positioning: Sei is now firmly established among the top 35 crypto-assets by market cap, with a trajectory reminiscent of other modular success stories.

Catalysts and Positive Outlook

• Protocol Roadmap: Key scheduled upgrades (multi-chain bridge expansions, on-chain order matching engine v2) expected H2 2025.
• Major Integrations: Launch of permissionless Layer 2 settlements and cross-chain DeFi primitives could dramatically boost TVL and user activity.
• Potential Institutional Entry: Ongoing dialogue with traditional asset managers; any sign of ETF/ETP productisation around Sei could serve as an explosive catalyst.
• Regulatory Clarity: Recent moves from key Asian and EU regulators position Sei as a compliant, investable infrastructure for both DeFi and RWAs (real-world assets).

Investment Strategies (By Time Horizon)

Short-term (<3 months):

• Structural Upside: Recent breakout from consolidation supports an immediate momentum play, especially on mild technical pullbacks to the $0.57–$0.59 zone.
• Catalyst Trade: Acute price reactions are expected around protocol upgrade or major dApp launch announcements.

Medium-term (3–18 months):

• Growth Re-rating: Anticipated ecosystem growth and DeFi integrations could drive fundamental re-pricing; ideal positioning is achieved before post-upgrade unlocks.
• Scaling Impulse: Q4 2025–Q1 2026 may see surge in TVL and on-chain volume if Layer 2 deployment reaches mainnet.

Long-term (18 months+):

• Secular Winner Thesis: Sei appears architected to benefit from the multi-chain/Web3 modularisation wave. Long-term holding could benefit from compounded ecosystem network effects and capital inflows as regulatory frameworks mature.
• Staking Yield: Attractive on-chain staking APY and network participation dynamics further enhance Sei's appeal for yield-seeking investors.
• Entry Tactics: Deploy capital opportunistically during broad risk-off moves or following ephemeral negative headlines, with core accumulation before major roadmap milestones.

Sei Price Projections (2025–2029)

Is Now the Right Time to Consider Sei?

In sum, Sei’s combination of resilient technicals, rapidly advancing fundamentals, and strategic ecosystem catalysts firmly establishes it as one of the outstanding modular Layer 1 opportunities for the coming cycle. Its consistently rising adoption metrics, deepening liquidity, and differentiated architecture support the thesis for a renewed investor focus. With recent protocol upgrades, high-profile partnerships, and an expanding global community, Sei could well be set to outperform both on a relative and absolute basis over the next cycle.

Given the sector’s ongoing transition to scalable, composable modular infrastructures—and Sei’s unique execution in this field—the fundamental and technical case for fresh capital deployment seems robust. The projected growth curve, reinforced by upcoming upgrades and an increasingly favourable macro-regulatory environment, justifies a sustained interest in Sei as a dynamic portfolio engine.

Ultimately, Sei remains a high-volatility digital asset that seems to offer excellent opportunities for active and patient investors alike. Its accelerating price trajectory showcases Sei’s capacity for swift, decisive upside—but, amid evolving macro conditions, disciplined risk management is imperative. For investors seeking exposure to the vanguard of Layer 1 innovation, Sei stands out as a compelling opportunity with potential for multi-year outperformance.

How to buy Sei?

Buying Sei (SEI) cryptocurrency online is easy and secure when you use a regulated platform. In the UK, you have two main options: buying Sei directly (“spot purchase”), which means you actually own the coins, or trading it via crypto CFDs, where you speculate on its price movements without owning the underlying asset. Each method suits different investment goals and risk profiles. To help you choose the right platform for your needs, a comprehensive comparison of trusted providers is available further down this page.

Spot Purchase

Spot purchasing Sei means you acquire real SEI tokens, which are then stored in your wallet (either on the exchange or a personal wallet). This method is ideal for those looking to directly own the asset and participate in the Sei network. Platforms typically charge a fixed commission per transaction, often ranging from £1.50 to £4 per order.

Example

Suppose the current price of Sei is £0.40 per coin. With a £1,000 investment, you could buy around 2,495 SEI coins (accounting for a £5 transaction fee).
- Gain scenario: If Sei’s price rises by 10%, your holding is now worth £1,100.
- Result: That’s a £100 gross profit, or +10% on your investment.

Trading via CFDs

CFD (Contract for Difference) trading allows you to speculate on Sei’s price without actually owning SEI coins. Instead, you open a position that tracks Sei’s price movement. Fees typically include the “spread” (difference between buy and sell prices) and possible overnight financing costs if you keep positions open beyond one day.

Example

With a £1,000 stake and 5x leverage, you control a £5,000 position on the Sei market.
- Gain scenario: If Sei’s price increases by 8%, your position gains 8% × 5 = 40%.
- Result: That’s a £400 gain on your £1,000 capital (before fees).

Final Advice

Always compare all fees (commissions, spreads, overnight charges) and platform conditions before investing, as they can vary widely. Whether you opt for direct purchase or CFD trading will depend on your goals and experience level.

Our 7 tips for buying Sei

The latest news about the Sei

SEI Investments Company posted record financial results in Q1 2025, with revenue and profit growth exceeding expectations. The company reported $551.3 million in quarterly revenues, reflecting an 8% year-over-year increase, and an operating income of $157.1 million, up 25% YOY, leading to a robust net income of $151.5 million (+15% YOY). Notably, earnings and revenue surpassed analyst forecasts by 4.46% and 0.86% respectively, contributing to a positive sentiment among institutional investors and reinforcing SEI’s reputation for operational consistency, which is particularly relevant for UK analysts tracking outperforming global fintech stocks.

Technical analysis signals have turned strongly positive, with SEI maintaining a ‘Strong Buy’ rating across all major short and long-term indicators. SEI stock is trading at $85.64, near its 52-week peak, supported by buy signals from moving averages (20-day, 50-day, 100-day, and 200-day) and a bullish MACD. The 14-day RSI stands at 62.29 (neutral-bullish), and price targets range from $85.20 to $88.00, with consensus analyst ratings at Moderate Buy. This strong technical posture is of special interest to UK investors looking for momentum plays on US-listed fintech equities.

Record-breaking net sales events demonstrate continued strong demand and organic growth for SEI’s technology solutions in institutional client segments. Q1 2025 net sales reached a record $46.6 million, and trailing 12-month net sales hit $153.2 million. The growth was broad-based, with investment managers (+19%), private banks (+34%), and investment advisors (+15%) all reporting improved operating profits. These indicators of client growth and product adoption reinforce SEI’s position as a trusted provider of technology-driven financial services, which UK-based institutional asset allocators increasingly consider for diversification and operational resilience.

SEI is rapidly expanding its international footprint, notably enhancing its Luxembourg depositary services, signalling a constructive trend for UK and European clients. The company’s continued internationalisation, including within key European financial hubs like Luxembourg, bolsters its appeal for UK market participants seeking credible technology and custodial partners post-Brexit. The doubling of its Integrated Cash Program contribution year-on-year further underscores its growing cross-border platform strength, offering UK institutions new opportunities to leverage SEI's global solutions.

Ongoing capital allocation through substantial share buybacks and a sustainable dividend policy provides additional attractiveness for UK income-focused investors. SEI repurchased $192.8 million in shares in Q1 2025 and continued its quarterly dividend with an ex-dividend date on 9 June 2025 and a forward yield of 1.15%. These capital returns support shareholder value and may particularly benefit UK investors, as SEI offers a blend of capital appreciation potential and consistent cash flows from the US fintech sector, making it a compelling portfolio candidate in the current environment.
