Pre-Seed Funding Ecosystem Shows Signs of Stability in Early 2026 : Research

Carta has indicated that the early-stage startup ecosystem in the United States showed notable resilience in the first quarter of 2026. This, according to the latest insights from Carta which noted that roughly 3,000 domestic companies secured pre-seed capital during this period, generating more than $2.3 billion so far. With additional deals still being recorded, the final tally is projected to approach $2.9 billion—consistent with totals observed in prior quarters.

According to the insights from Carta, this steady flow of capital points to a maturing market that has found a new equilibrium after years of volatility.

Pre-seed investments primarily rely on unpriced financing tools, with simple agreements for future equity (SAFEs) dominating the space.

Convertible notes, by contrast, hit a historic low, making up only 7% of deals and 8% of the total dollars invested.

This preference underscores SAFEs as the go-to instrument for founders and investors seeking speed and flexibility at the earliest stages.

One striking pattern is the growing polarization in round sizes. Average deal values for typical pre-seed financings are trending downward, yet the overall capital pool remains stable thanks to a handful of exceptionally large rounds.

This creates a barbell-shaped distribution: more modest checks at one end and outsized commitments at the other, with the mid-range ($1 million to $2.5 million) shrinking from 24% of rounds in Q1 2023 to just 18% in Q1 2026.

Smaller rounds below $1 million have gained ground, while those exceeding $2.5 million hold steady.

The artificial intelligence wave has intensified competition, channeling resources toward high-potential opportunities and widening this gap.

Capital volume at the pre-seed level has stabilized, with quarterly totals consistently landing between $2.5 billion and $3 billion.

This predictability offers founders a clearer sense of available resources compared to the turbulence of recent years.

The contraction in middle-tier rounds reflects broader market pressures. Investors appear more selective, favoring either lean, low-risk experiments or ambitious bets with breakout potential.

AI startups have been major beneficiaries, capturing around 50% of pre-seed dollars in Q1 2026—up sharply from roughly 30% just a few years earlier.

This mirrors trends seen in more mature venture stages and highlights how quickly AI has become central to early innovation.

Geographic shifts also stand out. The American South has strengthened its position, surpassing the Northeast in total pre-seed funding share for the quarter.

Miami emerged as a standout performer, ranking as the third-largest hub behind San Francisco and New York City, ahead of traditional centers like Los Angeles and Boston.

This momentum builds on ongoing efforts to diversify startup activity beyond coastal tech enclaves.

On the deal-structure front, valuation caps for SAFEs have continued their gradual upward trajectory.

Caps on convertible notes, however, have shown more volatility and do not always scale in line with larger round sizes.

These nuances matter greatly for founders negotiating terms, as they influence future ownership and dilution. Q1 2026 paints a picture of a pre-seed market that is more concentrated yet stable.

While AI drives much of the excitement and capital concentration, broader geographic diffusion and disciplined round sizing suggest a sector adapting to new realities. Carta concluded that  founders entering this environment should focus on clear differentiation—particularly in high-growth areas like AI—while paying close attention to regional advantages and evolving instrument preferences.
