The H1 2026 Seed Deal Terms Report

Seed deal terms in 2026 cluster around a tight default: post-money SAFE (81% share), cap-only structure (72%), median $20M cap, 1x non-participating preferred if priced, and pro-rata reserved for major investors only. SAFEs now make up 90% of pre-seed financings. Pay-to-play is the term that's actually moving, jumping to 42% of down rounds.

Most "guides to seed deal terms" you'll read in 2026 are clause-by-clause definitions of words. This one is a benchmark. The data below is what's actually closing in 2025–H1 2026, sourced from Wilson Sonsini, Carta, Cooley, AngelList, and Atomico, so you can walk into a term-sheet conversation knowing what's market and what isn't.

The seed deal terms landscape did move in 2025. Caps drifted up. The post-money SAFE locked in as the default. Discounts almost disappeared from SAFEs. Pay-to-play, dormant for three years, came back. Knowing the direction of travel matters as much as knowing the median, because every term you accept today is also a signal about what your next round will look like.

The mid-2026 default term sheet, at a glance

If you want the answer in one screen, this is it.

Read this table as the baseline. Anything an investor proposes that's harsher than these defaults is a negotiating ask, not a market norm. Anything more founder-friendly is a gift, take it.

SAFE terms 2026: caps, discounts, and the post-money lock-in

SAFE terms 2026 are simpler than they were two years ago, and the simplification is consistently in one direction.

The post-money SAFE, introduced by YC in 2018, has now decisively beaten its pre-money predecessor. Per Wilson Sonsini's FY2025 Entrepreneurs Report, 81% of SAFEs in 2025 were post-money. The remaining 19% are mostly legacy templates, founders re-using old YC docs, or specific situations (very small friends-and-family rounds) where pre-money still makes sense.

Why investors prefer post-money: dilution math is fixed at the time of the SAFE, not at conversion. They know exactly what percentage they're buying. Founders take more risk on stacking, because each new post-money SAFE you sign dilutes you on top of the existing ones, not alongside them.

Cap-only is the dominant economic structure. The FY2025 breakdown:

The takeaway: discount-only SAFEs are nearly extinct. If an angel proposes one, push for a cap. The market has moved.

The other quiet move: Carta's Q1 2025 data shows SAFEs were 90% of all pre-seed deals in the quarter, a record share. The convertible note is now a niche instrument used mostly when the parties want interest accrual or a maturity date. Of 4,611 pre-seed financings tracked by Carta in Q3 2024, 88% were SAFEs and just 12% were notes.

Valuation cap 2026: the numbers by stage and geography

The single most-asked question on a seed deal: what's a normal valuation cap 2026?

It depends on round size and geography. Here are the medians.

The WSGR $20M median is skewed upward by larger rounds; the Carta data is closer to what most founders actually see if they're raising under $500K. Use $7.5M–$10M as your floor on a pre-seed SAFE, $15M–$25M on a seed.

Caps also rose year-over-year. WSGR's FY2025 report showed the median SAFE cap climbing from $16M in 2024 to $20M in 2025, on a roughly $1M median SAFE raise. That's a 25% jump in 12 months, mostly driven by AI deal pricing pulling the median up.

Don't anchor on a number you read in a 2023 piece. The market for caps has moved up materially, and it moves up further every time an AI seed prices at $40M post.

Pro rata seed: why "standard" is a misleading word

Pro rata at seed is not standard. It's selective. This is one of the most miscommunicated terms in early-stage fundraising.

CRV's 2026 Pro Rata Rights guide is unambiguous: the NVCA model term sheet grants pro-rata only to "major investors" meeting a specific ownership threshold, typically 1–2% of fully diluted equity. That excludes most angels, most micro-VCs writing $50K–$100K checks, and most party-round participants.

YC's documents page reinforces this. YC's post-money SAFE templates (Cap-only, Discount-only, Uncapped MFN) do NOT include pro-rata. Instead, YC publishes a separate, optional Pro Rata Side Letter that founders can grant on a case-by-case basis. The two documents are deliberately decoupled so founders aren't forced to grant pro-rata as a default.

AngelList's Education Center confirms the same pattern: pro-rata is "typically awarded to select (not all) investors," and some investors "make receipt of these rights a prerequisite for investing." Read that twice. The expectation is negotiation, not assumption.

Why founders should care about this: every pro-rata you grant compresses the available allocation in your Series A. If 20 SAFE holders each have pro-rata on a $5M next round, your lead VC may find $1.5M of the round pre-committed to insiders before they even start sizing. That makes the round harder to syndicate and gives your lead less ownership for the same dollars.

CRV explicitly warns that granting pro-rata to many SAFE holders complicates Series A fundraising, and recommends restricting it to the largest check-writers and the next round only. This is the rule to follow.

The pro-rata side-letter shape that works

Use a YC-style Pro Rata Side Letter only when:

• The investor wrote a meaningful check. Define this with a dollar floor ($100K, $250K, $500K depending on round size) or a percentage floor.
• The pro-rata applies only to the next equity round, not all future rounds. Open-ended pro-rata is a future-Series-B problem you don't need yet.
• The investor must affirmatively exercise it. No automatic conversion if they don't fund.

That's the founder-friendly default. Anything broader is the investor asking for a favor, not a market term.

MFN, side letters, and where the real negotiation happens

The most leveraged terms on a seed deal are rarely in the SAFE itself. They're in the side letter.

CRV's 2026 term-sheet guide puts it directly: on SAFEs, "side letters are where most of the real negotiation occurs." The clauses to watch:

• Information rights. What financial data you owe the investor and how often. Quarterly investor updates and an annual cap table are reasonable. Monthly P&L for a $25K check is not.
• Pro-rata rights. Covered above. Restrict to major investors, next round only.
• Board observer seats. Avoid at seed unless the investor is a meaningful lead. Observer seats slow board meetings down and create awkward dynamics when you eventually price a Series A and need a real board.
• Future Major Investor status. This grants the holder the right to be classified as a "major investor" in the next priced round, which then auto-triggers all the major-investor protections (pro-rata, info rights, sometimes consent rights). It's a back-door to terms the SAFE didn't explicitly give.

MFN clauses are the under-discussed default. An MFN ("Most Favored Nation") clause lets a SAFE holder automatically swap their terms for the better ones you give a later investor. YC offers the "Uncapped MFN" SAFE as one of three standard post-money templates, so MFN is now genuinely baseline.

The reason MFN matters: it lets an early angel write a check without forcing the cap conversation, on the promise that they'll get whatever cap you eventually set for the priced lead. That's founder-friendly if you're raising before you know what your market price is. It's investor-friendly because they don't bear pricing risk.

The MFN clause to push back on is the "single-trigger" MFN that resets on every subsequent SAFE. Limit MFN to the next priced round only. Otherwise you're locking yourself into a cap ratchet for the entire SAFE life.

In our read of the 2025 SAFE market, the cap is almost never where founders lose. They lose in the side letter, on terms they didn't even know they were signing.

Priced seed term sheet trends: what's in the box if you skip the SAFE

If your seed round is priced (~10% of pre-seed deals, ~30% of seed deals), the term-sheet shape is more elaborate, but the defaults are remarkably founder-friendly heading into 2026.

Cooley's Q1 2025 Venture Financing Report shows the priced-round baseline across all stages:

Source: Cooley Q1 2025 Venture Financing Report; WSGR FY2025.

If your priced term sheet has 2x participating preferred with full-ratchet anti-dilution, that's a 2015 term sheet someone forgot to update. Push back, hard. You have the data on your side.

The Series Seed pre-money number worth knowing: WSGR's Q4 2025 data shows the median Series Seed priced pre-money at $29.0M on a median raise of $6.0M, up from $4.4M in Q3 2025. The median seed pre-money on Carta in Q1 2025 was $16M, so WSGR's higher number reflects a sample skewed toward larger and AI-heavy deals. Use the Carta number as your reality check.

Which seed round terms are tightening, and which are loosening

Most takes on "the market" treat all terms as moving together. They aren't. Some are loosening (good for founders), some are tightening (good for investors). Reading the direction of travel is how you anticipate what's coming on your next round.

Tightening (in investors' favor)

• Pay-to-play provisions. Per WSGR FY2025, pay-to-play appeared in 42% of down rounds in 2025, up from 27% in 2024. Cooley's Q1 2026 data shows pay-to-play at 7.3% of all deals. Translation: existing investors are increasingly being asked to put more money in to keep their full economics in a down round, which is mechanically rough on smaller seed investors who can't follow on.
• SAFE caps creeping up. Median SAFE cap rose from $16M to $20M in one year. On the surface that's founder-friendly, but it pulls forward dilution: a $20M cap at pre-seed is harder to grow into for a Series A than a $12M cap was three years ago. The implied Series A pricing required to keep dilution rational is now $40M+ pre, not $25M.
• MFN is now standard. YC's Uncapped MFN template normalized the MFN clause across the seed market. Most investors expect it. That's a constraint on founders' pricing flexibility on follow-on SAFEs.

Loosening (in founders' favor)

• Participating preferred is nearly dead. WSGR FY2025 showed participating liquidation preferences fell to 6% in 2025, the lowest share since 2021. Non-participating 1x is the universal default. Three years ago, a chunk of seed-stage rounds still saw participating preferred; today, it's a red flag.
• Discount-only SAFEs disappeared. Down from 14% in 2024 to 7% in 2025 per WSGR. The cap is now the locked-in mechanism for setting investor economics, which gives founders cleaner negotiating ground.
• Redemption and accruing dividends are minor. Cooley Q1 2025 shows redemption in only 2.8% and accruing dividends in 4.4% of deals. Both terms have effectively been written out of the seed market.

The two-line summary: economic terms loosened, structural terms (pay-to-play, MFN) tightened. If you're raising in H2 2026, expect to win on the economics and concede on the structural defaults.

Europe vs US: the gap is smaller than you think

One of the most outdated assumptions in seed fundraising is that European seed term sheets are a stripped-down version of US ones. They're not anymore.

Atomico's 2024 State of European Tech report shows median European seed round size hit $1.4M in 2024, up from $300K in 2015. That's nearly a 5x increase in a decade, and it puts European seeds within striking distance of US seed medians. The implication for terms: investor expectations have converged.

What's similar:

• SAFE-equivalents dominate. UK uses ASA (Advance Subscription Agreement); EU uses local SAFE variants. The economics are the same shape: cap, optional discount, MFN.
• Liquidation preferences mirror US. 1x non-participating is the standard. Full-ratchet anti-dilution is rare.
• Pro-rata is also selective. Major-investor thresholds apply in EU term sheets too.

What's different:

• Tax-advantaged schemes (SEIS/EIS in the UK) constrain instrument choice. SAFEs often don't qualify for SEIS/EIS relief, so UK founders frequently take ASAs or priced rounds even at very small sizes.
• Notary requirements in Germany, France, and the Nordics. Some EU jurisdictions require notarized signing for equity issuance, which adds cost and time to priced rounds and pushes founders toward convertibles.
• Cap medians run lower. A European seed cap at €6M–€10M is common where a US seed cap at $15M–$20M is the equivalent norm.

If you're a European founder pitching US investors, the playbook is to come in with a US-shaped term sheet and let local optimization happen in side letters. Don't lead with the SEIS reasoning. Investors don't care.

The push-back map: what to actually negotiate

You've seen the defaults. Here's what to push on if an investor proposes worse, and what to accept if they propose worse but it's a deal-breaker for them.

Walk-away terms are non-negotiable for a reason. Participating preferred and full-ratchet anti-dilution turn a moderately bad outcome into a disastrous one for founders. Redemption rights give investors a put option on your company that limits your strategic flexibility forever. The data shows fewer than 10% of 2025 deals had any of these. If an investor insists, they're either inexperienced or they don't actually want to invest, they're stress-testing your resolve.

If you're sending term-sheet-shaped messages to investors at scale (40+ outreach contacts, multiple parallel conversations), platforms like Causo handle the personalization and follow-up so you can spend negotiation time on the actual terms instead of the inbox.

FAQ

What are standard seed deal terms in 2026? Standard seed deal terms in 2026: a post-money SAFE (81% of SAFEs in 2025 were post-money) with a valuation cap only (72% are cap-only), 1x non-participating liquidation preference if priced (95% of priced rounds), weighted-average anti-dilution (100% of priced seeds), and pro-rata limited to major investors via side letter. Median US SAFE cap sits at $20M; median European seed round is $1.4M.

What is a typical SAFE cap for a seed round in 2026? The median SAFE valuation cap in 2025 was $20M on Wilson Sonsini deals, up from $16M in 2024. Carta shows tighter ranges by check size: $7.5M median cap for SAFEs under $250K and $10M for $250K–$500K SAFEs in Q2 2025. Caps cluster by round size, not by founder negotiating chops.

Are pro-rata rights standard at seed? No. Pro-rata at seed is selective, not universal. The NVCA model grants pro-rata only to "major investors" meeting a 1–2% fully-diluted threshold, and YC packages it as an optional Pro Rata Side Letter rather than baking it into the SAFE. Expect to negotiate, not assume.

What discount rate is normal on a seed SAFE? Discounts are increasingly rare on SAFEs. In 2025, 72% of SAFEs were cap-only with no discount, 21% combined a cap with a discount, and just 7% were discount-only (down from 14% in 2024). When discounts do appear on convertible notes, 40% of 2025 note deals used exactly 20%.
