July 1 (Reuters) - U.S. stocks rose sharply in early trading on Wednesday after Greek Prime Minister Alexis Tsipras signaled he was prepared to accept creditors' bailout offer with some conditions.
The Dow Jones Industrial Average, the S&P 500 and the Nasdaq Composite all rose nearly 1 percent, with financial stocks leading the gains.
Tsipras has sent a letter to the creditors outlining conditions for Athens' acceptance of a loan offer, a day after Greece defaulted on a 1.6 billion euro repayment to the International Monetary Fund.
However, euro zone officials said some governments would find it hard to accept Tsipras' conditions.
"Investors are taking a collective sigh of relief that an armageddon type of scenario did not occur with respect to Greece," said Adam Sarhan, chief executive of Sarhan Capital in New York.
"The markets are also rallying from deeply oversold level."
Contributing to the positive tone, U.S. private employers added 237,000 jobs in June, the biggest gain since December, suggesting further improvement in the jobs market.
U.S. Treasuries yields rose to session highs as the stronger-than-expected rise in jobs rekindled bets the Federal Reserve would raise interest rates later this year.
The Institute for Supply Management will release its June manufacturing data at 10 a.m. ET (1400 GMT). The data is expected to show an increase in manufacturing activity for the month.

Eight of the 10 major S&P 500 sectors rose.
